North Dakota's Salty Fracked Wells Drink More Water to Keep Oil Flowing  

Posted by Big Gav in , ,

National Geographic has an article on the water demands of North Dakota's shale oil wells - North Dakota's Salty Fracked Wells Drink More Water to Keep Oil Flowing.

It's well known that water has been key to the shale oil and gas rush in the United States. But in one center of the hydraulic fracturing boom—North Dakota—authorities are finding that the initial blast of water to frack the wells is only the beginning.

The wells being drilled into the prairie to tap into the Bakken shale need "maintenance water"—lots of it—to keep the oil flowing.

So while the water first pumped down the hole to crack rock formations and release the underground oil and natural gas typically totals 2 million gallons (7.5 million liters) per well, each of North Dakota's wells is daily drinking down an average of more than 600 gallons (2,300 liters) in maintenance water, according to recent calculations by North Dakota's Department of Mineral Resources (DMR). Without water, salt buildup forms and restricts the flow of oil.

A Convergence Of Interests ?

SP at TOD ANZ has an interesting conspiracy hypothesis about the Chinese purchase of Cubbie Station cotton farm and the massive need for water the booming coal seam gas industry has (invoking the ghost of Russ Hinze along the way) - Sinogetically stuffing the basins?.

Pulling a few strands months apart together, is there a link between Paul Sheehans story (below) about how the expansion of Coal Seam Gas production is going to impact water availability for downstream food producers with last years agreement to sell Cubbie station to a Chinese consortium (now completed).

Energy And Water  

Posted by Big Gav in

The SMH has an article on water and energy - Energy use sucking up a precious resource .

Australia's future growth is predicated on the expectation that China and India will continue to emerge as economic behemoths. But the explosion in energy use on which Australia's current boom is based is accelerating the water debt in both China and India.

The link between energy and water is rarely discussed, yet is of huge consequence. The problem was encapsulated in Steven Solomon's book, Water: The Epic Struggle for Wealth, Power and Civilization (2010). He later updated the dilemma in the Journal of Energy Security:

''Pumping, conveying, and treating water is extremely energy-intensive. Water is very heavy - 20 per cent more than oil - and massive volumes are required to sustain modern society . . . each day every person living in an industrialised nation personally consumes about [US]1000 gallons [3785 litres] embedded in the food we eat . . . ''

Think of that cup of coffee and its 140 litres. Or a single steak, which requires almost 10,000 litres of water to produce.

Solomon continues: ''While the 13-fold increase in energy use in the 20th century is often heralded as the signature factor in the unprecedented prosperity of a world population that has quadrupled to over 6 billion, it has been accompanied and also leveraged by a nine-fold increase in freshwater use . . .

''The largest single water user in the industrialised world is the energy industry. Prodigious amounts are needed to produce nearly every type of electricity and transport fuel across the energy value chain . . .

''But scaling up alternative technologies on a sustainable, massive level faces serious water scarcity hurdles. Getting additional oil out of existing wells through enhanced oil recovery techniques uses 15 to 1000 times more water. Potentially game-changing new coal, gas, and oil shale-based unconventional fuels that are shaking up world oil and gas markets are almost all roughly three to five times more water intensive . . . ''

It may seem counter-intuitive to be discussing water shortages in Australia after two of the wettest years in a century. The dams are high, Queensland and Victoria have had record floods, even the desert inland is awash. Last year was the third-wettest since we began keeping national records in 1900, following the second-wettest year on record. Both years were dominated by La Nina.

It was too much of a good thing. For the previous 10 years Australia suffered a long dry. The soil lost moisture. Thousands of hectares were also cleared for wheat and cotton. For soil conservation, the worst possible event with so much dry topsoil was for a sustained period of torrential rain. The erosion would be fearsome. That is exactly what happened. Today the land looks healthy, but thousands of square kilometres have seen topsoil eroded. We reached peak soil in eastern Australia a long time ago. The slow exhaustion of the soil has been hidden by the use of fertilisers. That is why the major food basket of Australia, the Murray-Darling Basin, is officially listed as ''at risk'' by the United Nations Food and Agriculture Organisation. ...

Insurance Australia Group, which owns NRMA, among other brands, predicts that floods, fires, heatwaves and drought will grow more extreme and Australia will be one of the countries most affected by climate change.

Our great emerging trading partners, China and India, will be no better off, because of water stress.

China's groundwater reserves are already over-exploited, and water tables are dropping. China has a strategic water shortfall. It has almost four times the population of the United States but only the equivalent of one-third of America's water resources.

India is worse off. It depends on the monsoons and flows from the Himalayan glaciers, which are retreating. India must sustain 20 per cent of the world's population with just 4 per cent of the world's freshwater. The strain is showing. In 1980, there were 2 million wells in India. Today there are 23 million. If wells are dug too deep, saltwater seeps into the aquifer causing irreparable damage. This is happening.

The Ganges is polluted and threatened by the loss of flow from the Himalayan glaciers. Water volume on the Indus - a river crucial to both India and Pakistan - is down 30 per cent.

As India's middle-class grows rapidly, its food and energy consumption leads to soaring water consumption. Something will have to give. Wealth or water.

Move Over, Electricity: Gas and Water Meters Are Getting Smart  

Posted by Big Gav in , ,

Greentech Media has a report on the expansion of smart metering to water and gas - Move Over, Electricity: Gas and Water Meters Are Getting Smart.

For all of the chatter about smart meters, the conversation rarely wanders far from the realm of electricity. But action is starting to heat up in the smart gas meter market, and water isn’t far behind.

Last week, consulting group Capgemini announced it was chosen by Southern California Gas Company (owned by Sempra) to install more than six million smart meters in the next five years, the largest gas-only utility smart meter project in the U.S. SoCalGas’s project is part of a nearly three-fold increase in the penetration of smart gas meters worldwide estimated by Pike Research between 2010 and 2016.

“The gas grid is certainly a different animal,” said David DuCharme, vice president of Utility and Smart Energy Services at Capgemini. “The largest issue is safety and management.”

In Europe, there is already more activity in the gas market; the U.K. government has mandated dual gas and electric smart meters for every home and business by 2020. Italy will install smart meters for all of its commercial gas customers and most residents by 2016.

Yet in the U.S., gas metering has not received as much attention -- or as many federal dollars -- as electric smart metering. However, the challenge of managing gas smart grid data can be less complex than electric meter data management, according to DuCharme. As prices continue to drop for the smart meter market, this will benefit the gas market, as well.

Like their electric brethren, gas utilities have struggled with integrating IT and OT when implementing the new metering systems. Capgemini, which has doubled its accounts in the smart energy space to 40, is finding increasing success with gas utilities. In the case of SoCalGas, about 30 different vendors will provide the meters; Aclara is providing the MDM system.

Water is also on the horizon. “The cost of efficiently managing infrastructure in the gas and water industry is extremely important,” said DuCharme. For those who think the electric grid in the U.S. is aging, the water infrastructure in much of the world is downright elderly. One study from Frost & Sullivan estimates the European smart water meter market will be worth $20 billion by 2020 and will see double-digit growth in the next decade.

City of Sydney plans recycled water network  

Posted by Big Gav in , ,

Clover Moore's Sydney city council seems to be plotting a slow secession from the electricity and water grids. The SMH has a report on an interesting plan for storing recycled water in local aquifers - City of Sydney plans recycled water network.

THE City of Sydney council is finalising plans for a recycled water network to be established throughout much of the city. It will include use of the Botany aquifer which extends from Redfern and Surry Hills, through Centennial Park and on to Botany Bay.

The rethink of the city's water supply comes as the council finalises plans to decouple the electricity network from the statewide supply grid, instead using a new network of power generators throughout the CBD which will provide cheaper and more reliable power to the city. ''If you're digging up the streets to put in the new trigeneration [electricity, heating and cooling] system, that's the golden opportunity to put in a recycled water network,'' the council's chief development officer for energy and climate change, Mr Allan Jones, said.

''Sixty per cent of the cost of the infrastructure is in the trenching and traffic management. That's why we're also looking at automated waste collection.''

The council recently outlined plans for an automated waste collection system, which remains under study. ''Piping water into the city and only drinking 2 per cent of that is just crackers,'' Mr Jones said. Taking into account cooking, and any possible way of ingesting water, no more than 20 per cent of the city's water needed to be of drinking quality, he said.

Central to the plan will use of recycled water and stormwater at new developments such as Barangaroo and Green Square.
Barangaroo will generate a surplus of recycled water which is expected to be used in water cooling towers and similar structures in other parts of the CBD.

Queensland Farm to use coal seam water for irrigation  

Posted by Big Gav in ,

The ABC has a report on an experiment in Queensland to use waste water from coal seam gas extraction for irrigation - Farm to use coal seam water for irrigation.

A project using treated coal seam gas water for irrigation and beef production has kicked off in Roma in southern Queensland. Gas company Santos says it's the first partnership between a coal gas producer and a family-owned agribusiness in Queensland.

President of Santos GLNG project, Mark Macfarlane, says the water goes through a vigorous process to ensure it's safe. "Processes called reverse osmosis and also water amendment, and it absolutely guarantees that we have the very highest quality of clean water that can be used to irrigate crops on their property," he said. "We'll be providing around about 700 megalitres of clean water over a four-year period."

EcoImagination: Water Recycling

Water reduction options for solar thermal technology  

Posted by Big Gav in , , ,

CSP Today has a look at water consumption in solar thermal power plants - Cooler, smarter options for hot CSP technologies.

NREL's study found that dry cooling would generally achieve a 90-92% decline in water consumption, with an increase in cost for generating electricity of 3-8%, depending on the climate.

“I think that 3-8% range is much smaller than what other people thought the actual impact would be (of dry cooling)," Macknick said. “In past years I had heard talk of 15-20% increases in cost, but that's not what we found."

Non-traditional water sources are the other option with the best potential for applicability at low cost, analysts say. Shallow brackish water and recycled wash water collected from mirror washing are the two options furthest along.

Squeegee clean

NREL has been working with researchers at the University of Colorado-Boulder on ways to reduce the amount of water used to wash CSP mirrors. Current practice usually involves spraying the mirrors with a hose, but a high-pressure spraying system with a squeegee involved could reduce washwater by 90% if it's automated, Macknick says.

While washwater reduction is great, in context it's a drop in the bucket compared to the daily water demand for wet cooling. About 20 to 30 gallons of washwater are used for every Mwh generated, compared to 700 to 900 gallons per Mwh used now for wet cooling.

“I think you definitely will see developers try all options, from using recycled wastewater or shallow brackish water, but there will still be issues with using those," Macknick said. “You may have a performance penalty to pump or treat that water, so I think development will be very site-dependent, and a lot of developers will start trying to locate themselves closer to those sources."

Non-water liquids could become feasible as a cooling source but would add considerably to capital costs, requiring another stage to cool down that liquid, which couldn't simply be evaporated like water. Some researchers are reportedly testing high-pressured carbon dioxide gas or ionized air.

Smarter siting?

Finding further cooling efficiencies may also drive CSP developers to choose sites more carefully. Basic thermodynamics of a CSP plant are based on the steam cycle, with thermal dynamic efficiency defined by inlet and exhaust temperatures. The ideal CSP locale would have clear, sunny skies but cold ambient temperature.

“The high desert area could be more attractive, or areas in Colorado that are 6,000 to 7,000 feet in elevation," Patel said. “But those areas are few and far between, or don't have easy access and grid connection. CSP also likes flat land, and the higher you go the tougher it is to get 200 acres of flat land."

When compared to water usage at coal-fired energy plants in the American southwest that includes water used during the coal mining, transport and cooling at the plant, CSP's wet-cooling system uses less water. And compared to biofuels based on corn or soybean, CSP wet cooling waters less per acre than those agriculture systems. With those points made, CSP uses more water per MW than a combined-cycle gas-fired plant.

“I think there will be some developments in hybrid-cooled systems," Macknick said. “There has to be a clever way we can utilize just a small fraction of the amount of water the wet-cool model uses now to achieve similar results. That's where the potential is at."

Victoria Government Rules Out Water Smart Meters  

Posted by Big Gav in , ,

Smart Meters.com reports that the Victorian government doesn't have the courage to rollout smart meters for water, following resistance to their electricity smart metering program - Victoria Government Rules Out Water Smart Meters, Despite Test.

Victoria, Australia will not be introducing water smart meters for household use after receiving a voter backlash against smart electricity meters, even though it conducted a test program in the southeastern suburbs. "Our Government will not be rolling our smart water meters for households in Victoria," stated Water Minister Tim Holding.

The State Government was looking to expand the bungled smart electricity meter system to cover water use as well, even though there were concerns that the system is useful for retail companies but causes household bills to rise.

Before ruling out the meter deployment, the Government conducted a trial by offering South East Water’s residential customers a $50 Myer voucher to participate, according to the Herald Sun.

Before the scrapping of this plan, there were revelations that residential smart electricity consumers will have to pay up to $285 per year just for having the meter. Electricity distributors have permission to recover smart meter installation costs directly from residential consumers.

To counter the customer concerns about bills, the Government-hired consultants gave the cynical suggestion of having a monthly billing period instead of a quarterly.
According to the Marchment Hill Consulting report for the Government, implementation of the water smart meter system will help water companies to reduce costs but it may not be able to reduce water price.

The smart meter system will give more control to households regarding water use management, however, it may cause "bill shock," says the report.

The water bill that an average household pays annually is already expected to reach $1000 this year with recovery process starting for the $3.5 billion Wonthaggi Desalination Plant.

Smart Water Meters Catch On in Iowa  

Posted by Big Gav in , ,

Todd Woody at The New York Times has an article on smart water meters in the US midwest - Smart Water Meters Catch On in Iowa.

While some California cities move to ban smart electricity meters over fears about their impact on human health, residents of Dubuque, Iowa, are embracing smart water meters.

Like smart electricity meters, smart water meters measure consumption and wirelessly transmit the data to utilities. In Dubuque, 311 households have volunteered to have smart water meters installed as part of a pilot project between the city and I.B.M. to see if giving residents information on their water use in real time will prompt them to conserve. The project is also intended to help city officials spot and repair leaks in the water system as they happen.

“The more frequently water use is monitored, the more quickly things like leaks can be detected and addressed,” Milind Naphade, program director for I.B.M.’s smarter city services, said in an e-mail. “Also, we’ll be able to better identify trends and patterns over time more quickly with this frequency.”

Many water bills are issued quarterly, so residents may not notice a spike in consumption as a result of leaks or other problems for months. The smart meters in Dubuque, on the other hand, will transmit data on a home’s water use to I.B.M. computers every 15 minutes.

Residents can go to a Web site to monitor their water use. ...

Cutting water use also saves the city energy costs as less electricity is needed for pumping, city officials noted. “What our volunteer households are accomplishing is the first step to understanding waste and ultimately the conservation of valuable resources to sustain life quality for generations to come,” Dubuque’s mayor, Roy D. Buol, said in a statement.

The pilot project began in September and will continue until December, I.B.M said. In the longer term, the city of 60,000 plans to roll out smart water meters to all of its households as part of a sustainability initiative called Dubuque 2.0.

Innovative Indian Desalination plant opens in Madras  

Posted by Big Gav in , ,

The BBC has a look at a new, energy efficient desalination plant in Madras - Innovative India water plant opens in Madras.

A desalination plant which begins operating in Madras on Saturday will provide some of the cheapest drinking water in India, backers say. They say that the plant will supply 1,000 litres of drinking water for just over $1 and could well be a "template" for other coastal Indian cities.

The company behind the plant says that it is the biggest in South Asia. It will provide 100 million litres of water a day to the city by filtering sea water under high pressure.

In comparison, the government-run water board supplies about 650 million litres of water to the city's seven million residents.

"We are using the advanced reverse osmosis technology. We are purifying the water by filtering it under high pressure. Unlike other desalination plants we are not boiling the water and as a result we are saving a lot of energy," Natarajan Ganesan, Joint General Manager of the Chennai Water Desalination company told the BBC.

Mr Ganesan said that because the plant used "energy recovering technology", electricity consumption was reduced - making water produced there arguably the most competitively priced in India. "It can be competitive even when compared to supplying water from natural sources like lakes. One has to spend lot of money on transport water from lakes," he said.

The plant will process 237 million litres of sea water per day. An initial treatment will remove solids present in the water, before it is passed through a membrane under high pressure.

The plant - which cost $140m - is the joint venture between an Indian company IVRCL and Befessa of Spain. It is built under the "deboot" system - design, build, own, operate and transfer.

US Company Set to Ship Billions of Gallons of Water from Alaska to India  

Posted by Big Gav in ,

TreeHugger has a post on a bizarre plan to ship fresh water from Alaska to India - US Company Set to Ship Billions of Gallons of Water from Alaska to India.

India is hurting for water. With rapidly growing populations of people and a rising middle class that is mimicking the wasteful water consumption habits well known here in the United States, coupled with poor water management practices, India is set to be one of the first parts of the world hit by a major water crisis. Still, does that mean shipping water from Alaska all the way to India is a smart solution? One Texas-based water supply management company, S2C Global Systems, thinks it is -- at least, it's smart for their bottom line, if not for the environment. They're all lined up to ship billions of gallons of water annually from an Alaskan city to India, and other parts of Asia and the Middle East.

Circle of Blue brings our attention to a press release on the company's website.

Sitka, Alaska will sell water from its Blue Lake Reservoir for a penny a gallon to Alaska Resource Management, a company formed by S2C and True Alaska Bottling, will export as much as 2.9 billion gallons each year, providing the city with as much as $26 million annually. It could earn as much as $90 million annually if it can sell off the rest of its maximum water right of 9 billion gallons.

According to Circle of Blue, "This will be the world's first large-volume exports of water via tanker: companies have tried unsuccessfully for more than two decades to break open the bulk water export market. Past attempts have been thwarted by daunting logistics, concerns about natural resource sovereignty and commodification as well as the availability of cheaper local sources."

Fresh water is set to be the next "big oil" of the world, with supplies in some areas growing exceedingly tight. Technologies from smart metering to irrigation management to purification all seem to be slower to reach areas like India than tankers of exported water. However, while businesses are dashing to find a profit in water exportation, water management will need to become far more popular globally if we're to avoid a worldwide water shortage.

S2C is set to start shipping water within eight months, using tankers that have a "Ozonating" system onboard to keep the water clean. The shipping of the water alone sounds incredibly energy intensive.

Water Adds New Constraints to Power  

Posted by Big Gav in

The NYT has an article on how water availability is becoming a constraining factor for the development of new power generation capacity (except for solar PV and wind power, which don't require any) - Water Adds New Constraints to Power.

In the Mojave Desert, solar developers are scrambling to secure permits to build vast expanses of new generating capacity. But they are discovering that cost and carbon emissions are not the only limiting factors in new energy decisions in California. They are bumping up against water scarcity.

In the United States, thermoelectric power generation — mainly coal, nuclear and natural gas — accounted for 41 percent of U.S. freshwater withdrawals in 2005, U.S. Geological Society data show.

“Typically, project developers have wanted to use water for cooling because it’s more efficient and capital costs are less,” said Terry O’Brien, the California Energy Commission’s deputy director for power plant licensing. “That makes the project more economic.”

But there is a growing awareness in California and throughout the United States that the use of water for energy generation may be reaching its limits.

California has extensive experience with water shortages, resulting in its adoption of a policy, included in the energy commission’s 2003 Integrated Energy Policy Report, that discourages freshwater use for power plant cooling. The commission’s regularly updated reports provide current data and set the parameters for state energy and conservation policies.

“It’s just not possible anymore in California, and increasingly anywhere, to find unlimited water for the old water-intensive cooling systems,” said Peter Gleick, president of the Pacific Institute, which researches water issues and advises on policy. “If you want to build a big central power plant, whether it’s oil, gas or nuclear, you can’t take the water for granted.”

In the past decade, water availability has increasingly had an effect on the reliability of power supplies in many countries, with droughts leading to temporary closings of nuclear plants in Australia, France, Germany, Romania and Spain. Similar shutdowns have been threatened in the United States.

For a thermoelectric plant, the cooling technology used is the biggest factor in its water needs.

Once-through cooling, an inexpensive, energy-efficient and therefore widely used process, sucks up huge quantities of river, lake, or sea water. A typical 500-megawatt power plant takes in almost 19 million gallons, or 72 million liters, an hour, according to a 2005 report from the U.S. Department of Energy.

After running through the plant, almost all of this is returned to the river, lake or ocean. The used water, however, may be polluted, and the heat that it has absorbed can be lethal to fish, while the intake can kill wildlife and microorganisms. Research of the environmental consequences has led to tighter regulations in recent years, making it nearly impossible to get permits for new plants using once-through cooling anywhere in the United States.

The California state water board, going further, adopted rules this month tightening environmental protection requirements for existing coastal once-through plants — a step toward phasing out the technology at 19 plants. The U.S. Environmental Protection Agency is evaluating whether to follow California’s lead.

As once-through cooling has fallen out of favor, wet cooling, which exploits the chilling effect of evaporation, has become more common. It uses only about 3 percent of the water needed for once-through cooling — but it loses 90 percent of that to vapor. Wet-cooling systems are more expensive to build than once-through and consume as much as 3 percent of the energy generated by the plant. But a point in their favor is that they can use non-freshwater sources, like wastewater or mine pools.

Recent government data show that 56 percent of U.S. thermoelectric generating capacity is now wet-cooled, against 43 percent using once-through systems.

A newer process, dry cooling, which uses fans to push waste heat into the atmosphere instead of into water, is still more expensive and less efficient. On hot days, as much as 15 percent of the energy generated by a plant may be expended on cooling, according to the Electric Power Research Institute, a research body funded by the energy industry.

Tainted Nuclear Power Plant Water Reaches Major New Jersey Aquifer  

Posted by Big Gav in , ,

MSNBC has a report on one of the side effects of "clean, green" nuclear power - radioactive wter - Tainted Nuclear Power Plant Water Reaches Major NJ Aquifer.

Radioactive water that leaked from the nation’s oldest nuclear power plant has now reached a major underground aquifer that supplies drinking water to much of southern New Jersey, the state’s environmental chief said Friday.

The state Department of Environmental Protection has ordered the Oyster Creek Nuclear Generating Station to halt the spread of contaminated water underground, even as it said there was no imminent threat to drinking water supplies.

The department launched a new investigation Friday into the April 2009 spill and said the actions of plant owner Exelon Corp. have not been sufficient to contain water contaminated with tritium.

Tritium is found naturally in tiny amounts and is a product of nuclear fission. It has been linked to cancer if ingested, inhaled or absorbed through the skin in large amounts.

“There is a problem here,” said environmental Commissioner Bob Martin. “I am worried about the continuing spread of the tritium into the groundwater and its gradual moving toward wells in the area. This is not something that can wait. That would be unacceptable.”

The tritium leaked from underground pipes at the plant on April 9, 2009, and has been slowly spreading underground at 1 to 3 feet a day. At the current rate, it would be 14 or 15 years before the tainted water reaches the nearest private or commercial drinking water wells about two miles away.

But the mere fact that the radioactive water — at concentrations 50 times higher than those allowed by law — has reached southern New Jersey’s main source of drinking water calls for urgent action, Martin said.

iMeter Smart meters save energy, water, and dollars  

Posted by Big Gav in , , , , , ,

Todd Woody has an article at Grist talking about the benefits of expanding the smart meter / smart grid idea from the electricity grid to the water supply network - Smart meters save energy, water, and dollars.

The other day I came home to find a colorful flyer on my front door proclaiming, “Your meter just got smarter.”

While I was out and about in Berkeley, a worker from my utility, PG&E, slipped in the side gate and gave my old gas and electric meter a digital upgrade. So-called smart meters allow the two-way transmission of electricity data and will eventually let me monitor and alter my energy consumption in near real-time. I’ll be able to fire up an app on my iPhone and see, for instance, a spike in watts because my son has left the lights on in his room and a laptop plugged in.

Now I only learn of my electricity use when I get my monthly utility bill, long after all that carbon has escaped into the atmosphere. The situation is even worse when it comes to water consumption; my bill and details of my water use arrive every other month.

“When you tell people what total bucket of water they used in the past 60 days, the barn door is open and the animals are long gone,” says Richard Harris, water conservation manager for the East Bay Municipal Utility District, my local water agency.

EBMUD is currently testing smart water meters in 30 households and plans to expand the pilot program to 4,000 homes and businesses later this year.

“It’ll give us better knowledge of where our water is going,” says Harris. “We also thought if we’re going to ask people to use water more efficiently, especially when we’re coming out of a drought and have imposed water restrictions, customers need to have an idea of what their current use is.”

EBMUD’s smart meters take readings every hour and participants in the pilot program will be able to go online to check their consumption and set up an email alert if their water use rises above a certain level. The agency also plans to offer a social networking feature to allow people to compare their water consumption with other households in the area. Nothing like a little peer pressure to get you to turn off the tap.

Given that many states expect to face water shortages in the coming years, one would think we’d be seeing a roll out of smart water meters akin to the national effort being made to smarten up the power grid.

The payoff could be enormous. Water agencies and consumers would be able to detect leaking pipes and toilets in real-time and fix the problem before the water literally goes down the drain.

Smart grids continue to be the one area of the cleantech world that is really booming this year, so I'll do a little roundup of recent articles.

EETimes points to a recent report predicting their will be over 200 million smart meters deployed by 2014 - Report: Smart meters rise to 212 million in 2014.
Deployments of smart electricity meters worldwide will rise from 76 million in 2009 to reach about 212 million in 2014, according to a new report from ABI Research. The report provides forecasts of the wired and wireless communications options used to connect meters as well as profiles of some of many smart meter makers.

The move to smart grids and two-way meters to enable new services to the home got a $3.4 billion boost from economic stimulus grants in the U.S. this year, noted Sam Lucero, a practice director at ABI and author of the report.

For its part, the European Union enacted a so-called Third Energy Package in September which aims to migrate every European electricity meter to a capability for two-way communications by 2022. China is said to be ramping up its own smart grid programs, Lucero added.

Smart Grid News has a look at some possible changes to the energy market configurations as a result of smart grid implementation - Why Today's Utilities May Soon Be Obsolete (and What May Replace Them).
The potential for implementation of a Smart Grid depends upon the paradigm or paradigms that are eventually implemented, as well as on the quantity and quality of information being exchanged. ... Two major questions are paramount across all models:

* Who makes the decisions?
* How is control exercised?

These crucial questions determine who applies the smarts to the grid and how efficiently those smarts realize the promise of Smart Grid technologies.

Attempting to create a taxonomy of market structures risks over-simplification, but the resulting clarity can be insightful. This said, I argue that there are four market models that capture the critical elements of what will emerge when the Smart Grid is fully implemented. While elements of the four can be mixed and matched, at the core they represent extremes that require dramatically different deployment strategies in information and data flow, as well as end user decision and control.

These are:

* Pure Market
* Intermediated
* Microgrid
* Centrally Controlled



Reuters has a look at the smart grid investment landscape - How to make a play in the smart electrical grid: executives.
The privately-held Silver Spring Networks is smart grid networking company and is often cited as a candidate for an initial public offering.

The smart grid will allow two-way communications between utilities and their customers. Analysts have said it will marry clean power, electric vehicles, advanced meters, and power storage into a seamless network, modernizing thousands of miles of outdated power lines and allowing for more efficient energy use.

Increased momentum for smart grid technology helped push power storage and energy efficiency stocks to perform the best on the WilderHill New Energy Global Innovation Index in 2009, which tracks the performance of 86 global clean energy stocks.

The sector also has seen a boost from the Obama administration, which announced a $3.4 billion package in 2009 to help build a smart electric grid meant to trim utility bills, reduce blackouts and carry power generated by solar and wind energy.

"The scale is even bigger than the Internet ... but the speed of adoption is still going to be slow," said Adrian Tuck, chief executive at Tendril, a Boulder, Colorado-based smart grid company that GE recently acquired a stake in. ...

"Demand response is the killer application in this market, at least the first killer app," said Robert W Baird analyst Michael Horowitz. "These guys already have built fairly good business momentum over the last couple of years, as consumers and utilities alike are looking for better ways to manage delivering electrons," he added.

While bigger players are moving into the sector, they may not be the fastest way to profit from the smart grid. Google has invested in smart grid player Silver Spring Networks while Cisco and Microsoft are seeking to leverage their existing networking and software expertise in the emerging sector.

"Our view is the pure play companies are going to give a lot more bang. This is going to be very small to incremental for a company like Cisco and Microsoft," said RBC Capital Markets analyst Stuart Bush.

Back at Smart grid News, a look at some of the issues that are cropping up as utilities try to phase out jobs like meter reading as smart meters are rolled out - Is the Smart Grid Inducing Labor Pains?.
It seems that there is a bit of wire crossing happening amid the hardworking folks who are actually many of the hands and feet creating and managing the Smart Grid. In spite of very positive initial reactions to the federal investment of billions into the creation of the Smart Grid, the law of unintended consequences is introducing some consternation among the ranks of organized labor as Smart Grid programs move from philosophy to reality.

While the introduction of the Smart Grid Investment Grant (SGIG) program was applauded by many in the labor community as the beginnings of a new market for skilled technicians, such as in this AFL-CIO blog post, or this IBEW promotional video, some actual deployments are not being greeted as positive changes.

Most recently, on Jan. 19 the Kennebec Journal reported that IBEW Local 1837 was "speaking out against" a new smart meter installation project by Central Maine Power (CMP) that had been funded to the tune of $96M through the SGIG, and which had a total cost of roughly $190M. Seems that the project would likely eliminate, over time, some 141 positions, and that did not sit well with the union.

The tension at CMP, however, is not unique. In October, a plan by the board of Memphis Light, Gas and Water Division (MLGW) received similar criticism from the IBEW, which noted that roughly 400 meter reading jobs would be lost in that plan.

The Smart Grid is comprised of much more than just smart metering. It involves redundancy, and resiliency, and quality of power, and ease of integrating renewables, and storage, and on and on and on. Today's unfortunate reality, however, is that investment has been increasingly targeted to smart metering. Smart meters, and the improvements in automating, and "remotifying" the reading, turn-on, and cut-off of power, are seen as early wins. They do not appear to jeopardize the delivery of power, and can very quickly demonstrate cost efficiency by decreasing truck rolls. This is both a reaction to the government's emphasis of "shovel-ready" projects to fund, and to the ease with which a utility can justify the project to regulators as a cost-saver, paying off the capital cost in short order through a reduction in labor costs. As a result, the union teams, originally anxious to generate skilled labor to drive the construction of the next generation of transmission and distribution, is left, instead with a short-term need for installers that will be wiring up the elimination of hundreds of jobs for their meter reading brethren.

Greentech media has a look at the top 10 smart grid news stories from 2009 - The Past and Future of Smart Grid.
8. Distribution and Transmission Up Next: Not all smart grid systems are visible to the untrained eye. Upgrading distribution and transmission grids with communications and controls could help utilities squeeze up to 10 percent more efficiency out of their existing generation capacity, according to the Electric Power Research Institute. Those savings can come from preventative maintenance and replacement, shortening outage times, and optimizing grid voltages, among other sources.

At the same time, managing the massive growth in renewable solar, wind and geothermal energy that will be needed to cut the nation's carbon emissions will put new pressures on the grid. Hundreds of billions of dollars will need to be spent on new transmission lines to carry Midwest wind power and Southwest solar power to load centers, according to studies - which opens up new business models for startups.

And at the neighborhood level, distribution grids will need a whole host of new technologies to manage the increase in rooftop solar panels, demand response-enabled homes, and future plug-in hybrid and electric vehicles that will soon place unprecedented new pressures on utilities built on the model of delivering power from central generation stations to millions of customers.

9. Smart Grid 2.0: All of these emerging smart grid technologies will be a lot more useful if they can be linked together. That's the idea for the next surge in the industry – a whole ecosystem of smart architectures, stretching from generations sources and transmission lines to the wireless and wired networks in utility customers' homes and businesses.

GridPoint, one of the more prominent – and well-funded – of the smart grid startups out there, is centered on delivering this kind of integrated offering to utility customers. Its approach has included buying up a host of startups offering vehicle charging, home energy monitoring and industrial and commercial energy management, indicating the breadth of functions it hopes to provide.

What will the smart grid of the future look like? Duke Energy CEO Jim Rogers speaks of a utility-managed system that orchestrates smart meters, solar panels, batteries, demand response systems and plug-in vehicle chargers to serve as "virtual power plants" scattered throughout a utility service territory.

CNet has an article on a in-house energy usage display that is combined with a thermostat (I suspect we'll see a trend for convergence in home based control devices over time which mirrors that of hand held devices) - CES: To save energy, thermostat becomes mini computer.
There are dozens of companies making in-home displays designed to help consumers shave energy use at home. But SilverPac is packing many of those features into a high-tech thermostat. SilverPac, which makes digital picture frames and other media electronics, on Monday introduced the SilverStat 7, a sleek device that combines the heating and cooling controls of a programmable thermostat with a real-time energy display. ...

The thermostat is built around a 7-inch touch-screen display that runs Windows CE on Intel's Atom processor. It has a Wi-Fi interface that will allow it to get electricity usage information from smart meters and talk to network-aware appliances on a home wireless network. It has built-in speakers to play FM radio or music streamed from a home network. People can also use the device as a calendar.

According to the company, SilverPac's in-home energy display will rely on getting information from a smart meter, which means that it won't be accessible to everyone. Even with millions of smart meters expected to be installed over the next three years, many utilities will not be making meter information available over home wireless networks, in part because of security concerns.



Smart meter programs in Australia are still in their infancy - Western Australia recently announced the first step in a local smart meter rollout - IBM nabs WA smart meter deal .
RESIDENTS in parts of Western Australia will soon be able to tell exactly how much power each electrical appliance consumes.

Western Power hopes to roll out 10,500 smart meters as part of its smart grid project, aimed at helping customers identify consumption patterns. As a result, households and businesses could lower their power bills as smart meters make usage monitoring more transparent.

IBM bagged a key contract with energy supplier Western Power to provide systems integration and project management services for the smart grid trial, due for completion in June 2012. ...

IBM is involved in almost 50 smart grid projects worldwide, including local utilities Energy Australia and Country Energy.

The federal government has pledged up to $100m towards the nation's first national smart grid. A government-backed smart infrastructure conference, ThinkFuture, will be held at Parliament House in Canberra on March 12.

SmartMeters.com has an article on some turbulence being encountered by a smart meter rollout in New Zealand - Second thoughts about smart meters in New Zealand.
A question has been raised in New Zealand whether the primary motivation for smart meter installations is so power companies can recoup funds from customers where were undercharged previously.

Three major utilities – Contact, Genesis, & Meridian – are all installing smart meters throughout New Zealand claiming the devices will conserve energy and save money for customers. The devices allow for remote meter reads so human meter readers don’t have to be sent out. The smart meters also use information technology to record and display power usage.

The New York Times has a look at consumer unhappiness with smart meter rollouts in the US as well - ‘Smart’ Electric Utility Meters, Intended to Create Savings, Instead Prompt Revolt.
Millions of households across America are taking a first step into the world of the “smart grid,” as their power companies install meters that can tell them how much electricity they are using hour by hour — and sometimes, appliance by appliance. But not everyone is happy about it. Leo Margosian of Fresno, Calif., said his meter put July use at three times as much as last July's.

Customers in California are in open revolt, and officials in Connecticut and Texas are questioning whether the rush to install meters benefits the public.

Some consumers argue that the meters are logging far more kilowatt hours than they believe they are using. And many find it unfair that they will begin to pay immediately for the new meters through higher rates, when the promised savings could be years away.

Power companies say the meters will allow utilities to vary the price charged to their customers by the hour to correspond to what those utilities are paying for energy in the wholesale market. This can help consumers save money, they say.

They also say the meters will be crucial to remaking the electric system to handle intermittent power sources like wind turbines and solar cells while continuously meeting customers’ needs. ...

In response to a wave of complaints from the Bakersfield area in the Central Valley, Pacific Gas & Electric has been placing full-page advertisements in newspapers in the area promising benefits from the new meters. It says customers will save money not only by paying rates based on hourly fluctuations in the wholesale market, but also eventually by displaying real-time rates.

To reduce their bills, customers could cut back at pricey peak times and shift some activities, like running a clothes dryer or a vacuum cleaner, to off-peak periods. Utilities will then have lower costs, the argument goes, because the grid will need fewer power plants as demand levels out.

Customers will become “structural winners,” said Andy Tang, senior director of the company’s Smart Energy Web program.

Someday utilities hope to use the meter to control consumption by major appliances like air conditioners. But experts are still debating what technical standards the meters and appliances should use to communicate.

The Energy Collective has an article on the need to educate consumers about the long term benefit of smart meter rollouts (though I think the fact that some smart meters just aren't that smart, or they help utilities adopt a utility centric model rather than a customer centric one - like the horrible example above of utilities controlling customer air conditioners rather than customers configuring their own response to high power prices, needs to be addressed - many of these programs are far from perfect) - Connecting the Smart Grid Dots One Meter at a Time.
There are more signs that the brouhaha over PG&E’s smart meter rollout may do damage to other utilities’ plans for similar deployments. News reports indicate that utilities and regulatory agencies in other states are closely watching the legal tangle devolve in California. Consumer advocacy groups in California are concerned that smart meters are expensive, inaccurate and increase their bills, and only benefit utilities by eliminating meter reading jobs. This clearly demonstrates that they and the consumers they represent see the immediate impacts of the rollout of smart meters – a highly visible and disruptive new technology – as negatives. To them, the smart meter is an unwelcome revolutionary technology with no benefits to average ratepayers. They don’t know about its evolutionary role in the Smart Grid and how it will help ratepayers save money AND the environment.

And why should they? It’s the responsibility of utilities, and maybe the Department of Energy (DOE) as well to educate consumers better about what Smart Grid technologies can do today and in the future. The DOE has developed a series of booklets that explain the benefits of the Smart Grid to various groups, including consumers, but clearly there need to be much more aggressive and coordinated campaigns to enlighten consumers.

Does Joe Ratepayer understand that smart meters enrolled in utility programs will reduce or eliminate the need to build more power plants to address peak electricity load requirements? Does Jane Ratepayer understand that new power plant construction translates into higher electricity bills to recover costs? Could Joe or Jane intuitively understand how a smart meter saves them money and saves the environment too?

Those of us in the business understand that smart meters will save consumers money on their utility bills as the grid evolves to residential Time of Use (TOU) electricity rates and Home Energy Management Systems (HEMS) are deployed. (Note: The Smart Grid Dictionary defines TOU as “A rate structure with different unit prices for electricity use in a 24-hour timeframe, generally to encourage use during periods of lower demand. This price applies to a time-of-use price, rate, or tariff and is a dynamic price scheme typically used with non-dispatchable demand response programs. It is also known as time-of-day pricing.”)

Analogies can help explain the Smart Grid rollout process and the role that smart meters play. For instance, let’s say that I am building a new house with the kitchen of my dreams. I won’t get the benefits of that kitchen’s output until foundations to fixtures are installed.

The smart meter is like my house’s foundation. There’s no home without a foundation. There’s no Smart Grid without smart meters. In building my new home, I understand that there is a start and a finish to the project. I have a blueprint to visualize the goal. I have a project plan to understand the process of achieving that goal.

It is vital for utilities to connect the dots between current smart meter rollout activities and long term Smart Grid objectives. Ratepayers and consumer advocacy groups need equivalent blueprints and project plans to understand the long-term objectives in terms of what it means to their bills and the environment.

The New York Times also has a look at experiments investigating the psychology of electricity consumption - Will 'Smart' Electric Meters Lead to Smarter Consumers ?.
In conjunction with utilities, tech companies and state and federal agencies, Stanford University is doing a number of experiments to see how psychology affects people's energy consumption.

Researchers say that when it comes to demand-side management, the field of psychology has been lying fallow for far too long, particularly in the residential sector.

"California has huge amounts of money to put toward marketing campaigns, and they spend it all on media marketing campaigns that we know don't work," said Carrie Armel, a research associate at Stanford University's Precourt Institute for Energy Efficiency. "Tens, hundreds of billions of dollars are going to be spent on installing smart meter technology. How much is being spent on behavioral research? Nothing. That's mind-blowing."

Economists and policymakers have long advocated real-time pricing as a way to reduce consumption and smooth demand at peak times. California's 2001 energy crisis might have been avoided had customers had a direct incentive to conserve power; the state Public Utilities Commission has experimented with at least three different pricing mechanisms since 2003, and is currently aiming to install smart meters in the majority of consumers' homes by 2011.

Stanford researchers are working on a dozen different studies on how behavioral patterns can create barriers to adopting new technologies and practices. The projects target four categories -- policy, technology, community and media -- with the aim of creating tools to tap into people's natural proclivities.

Coal seam gas deal promises water boost ?  

Posted by Big Gav in ,

Somehow I don't think will turn out well. The ABC has a report that a Queensland town is looking to reinject water from coal seam gas fields into the towns aquifers - yet one of the key environmental problems with CSG is what to do with the contaminated water produced as a by-product - are they plannming on filtering this stuff before putting it into the water supply ?. Mine deal promises water boost.

The Maranoa regional Mayor says a deal with a mining company could solve Roma's water problems. Rob Loughnan says Santos will start injecting water from its coal seam gas fields into the town's underground aquifers.

The project is expected to start within the next six months and councillor Loughnan says the company also plans to sell water to the district's farmers. "But recharging the aquifer is assisting the whole community. It's certainly something I'll be promoting as a great win for south-west Queensland out of all this activity," he said.

Osmotic power plant to debut in Norway  

Posted by Big Gav in , ,

Cleantech.com has an article on a Norwegian power plant demonstrating power from osmosis, quoting some large potential numbers for global power generation (I'd love to see an EROEI calculation for this - could it be positive ?) - Osmotic power plant to receive royal debut in Norway.

The world’s first osmotic power plant is expected to open next month at Tofte, outside of Oslo. And the facility will be getting an imperial unveiling from the Crown Princess Mette-Marit of Norway.

The plant, being developed by Norwegian state-owned electricity company Statkraft, is expected to generate power from energy retrieved from the difference in the salt concentration between seawater and river water, Statkraft said today.

With the technology, saltwater and freshwater are funneled into separate chambers, divided by an artificial semi-permeable membrane, according to Statkraft. The salt molecules in the seawater pull the freshwater through the membrane, increasing pressure on the seawater side. The pressure comes in the form of a 120-meter water column or waterfall that can be utilized in a power generating turbine.

Statkraft said today it has been researching the renewable and emissions-free energy source for the past 10 years.

In theory, osmotic power plants can be located wherever rivers meet the sea. The plants are quiet and can be integrated into existing industrial zones, such as the basements of industrial buildings, the company said.

The prototype—which has been under development for more than a year in cooperation with research and development organizations from various countries—is expected to open Nov. 24, with limited, undisclosed production capacity. It will be used for testing and development. Financial details were also not disclosed.

Within a few years, Statkraft plans to construct a commercial osmotic power plant.

Statkraft said the global potential of osmotic power is estimated at 1,600-1,700 terrawatt hours per year, or the same as 50 percent of the European Union’s total power production.

Water shortage threatens two million people in southern Iraq  

Posted by Big Gav in , , ,

The Guardian has a report on the impact of falling water levels in the Euphrates river in Iraq - Water shortage threatens two million people in southern Iraq.

A water shortage described as the most critical since the earliest days of Iraq's civilisation is threatening to leave up to 2 million people in the south of the country without electricity and almost as many without drinking water.

An already meagre supply of electricity to Iraq's fourth-largest city of Nasiriyah has fallen by 50% during the last three weeks because of the rapidly falling levels of the Euphrates river, which has only two of four power-generating turbines left working.

If, as predicted, the river falls by a further 20cm during the next fortnight, engineers say the remaining two turbines will also close down, forcing a total blackout in the city.

Down river, where the Euphrates spills out into the Shatt al-Arab waterway at the north-eastern corner of the Persian Gulf, the lack of fresh water has raised salinity levels so high that two towns, of about 3,000 people, on the northern edge of Basra have this week evacuated. "We can no longer drink this water," said one local woman from the village of al-Fal. "Our animals are all dead and many people here are diseased."

Iraqi officials have been attempting to grapple with the magnitude of the crisis for months, which, like much else in this fractured society, has many causes, both man-made and natural.

Two winters of significantly lower than normal rainfalls – half the annual average last year and one-third the year before – have followed six years of crippling instability, in which industry barely functioned and agriculture struggled to meet half of subsistence needs.

"For thousands of years Iraq's agricultural lands were rich with planted wheat, rice and barley," said Salah Aziz, director of planning in Iraq's agricultural ministry, adding that land was "100% in use".

"This year less than 50% of the land is in use and most of the yields are marginal. This year we cannot begin to cover even 40% of Iraq's fruit and vegetable demand."

During the last five chaotic years, many new dams and reservoirs have been built in Turkey, Syria and Iran, which share the Euphrates and its small tributaries. The effect has been to starve the Euphrates of its lifeblood, which throughout the ages has guaranteed bountiful water, even during drought. At the same time, irrigators have tried tilling marginal land in an attempt for quick yields and in all cases the projects have been abandoned.

Electricity From Salty Water  

Posted by Big Gav in , ,

Physics Central has an article on generating power using salinity differentials between different bodies of water (which I once dubbed "The Power Of Osmosis") - Electricity From Salty Water.

A device that gleans usable energy from the mixing of salty and fresh waters has been developed by University of Milan-Bicocca physicist Doriano Brogioli. If scaled up, the technology could potentially power coastal homes, though some scientists caution that such an idea might not be realistic.



Extracting clean, fresh water from salty water requires energy. The reverse process?mixing fresh water and salty water?releases energy. Physicists began exploring the idea of extracting energy from mixing fresh and salty waters, a process known as salination, in the 1970s. They found that the energy released by the world?s freshwater rivers as they flowed into salty oceans was comparable to "each river in the world ending at its mouth in a waterfall 225 meters [739 feet] high," according to a 1974 research paper in the journal Science. But those who have chased the salination dream have collided with technological barriers.

Brogioli has developed a new approach to salination, a prototype cell that relies on two chunks of activated carbon, a porous carbon commonly used for water and air filtration. Once he jump starts the cell with electric power, all that is required to produce electricity are sources of fresh and salty water and a pump to keep the water flowing. When the separate streams of salty and fresh water mix, energy is released.

A typical cell would require about three dollars worth of activated carbon, and, given a steady flow of water, the cell could produce enough electricity to meet the needs of a small house. It's the equivalent, in hydroelectric power, of running your appliances from a personal 100 meter (338 feet) high waterfall.

Salination would be an ideal technique for places where fresh and salty waters naturally mix, such as estuaries, according to Brogioli. He said that a coastal community of about a hundred houses could set up a plant with minimal damage to the ecosystem. "A salinity difference plant will be much smaller than a solar plant," he said. The only waste product is slightly brackish water that can be poured directly into the sea or, Brogioli suggested, into ponds that support estuary-friendly flora and fauna.

Instead of using fresh water, an increasingly scarce global resource, a salinity power plant could use water that is polluted or slightly contaminated with salt, giving new life to unusable water, Brogioli said. Seawater could also be mixed with high-salinity water, obtained by evaporating seawater?perfect for a desert community with little fresh water but sunshine to spare.

"Preliminary evaluations confirm that the setup can be scaled up to very big plants suitable for powering whole cities," said Brogioli.

Scientists agree that Brogioli's concept is sound but are cautious to declare it practical on a large scale.

"I don't see any reason why it should not work," said Yury Gogotsi, director of the A.J. Drexel Nanotechnology Institute at Drexel University in Philadelphia. "Capacitor desalination has been demonstrated and commercialized, and this can be called reverse capacitance desalination. It appears to be a logical approach. Of course the challenge is the practical implementation."

George Crabtree, a senior scientist at Argonne National Laboratory in Illinois, said he likes that the device extracts the energy as immediately usable electricity. But he sees difficulties in scaling up from a lab experiment to megawatt plants that could compete with wind turbines or other clean energy sources. Crabtree thinks the water requirements might limit the technology to large river deltas, like the mouth of the Mississippi. The energy it could potentially generate, he said, "is significant ... [but] not enough to solve everyone's problems."

Solar Thermal Power And Water Constraints In The US  

Posted by Big Gav in , , ,

MSNBC has an article about concerns about water availability slowing progress on solar thermal power development in the western US - Desert clash in West over solar power, water.

A westward dash to power electricity-hungry cities by cashing in on the desert's most abundant resource — sunshine — is clashing with efforts to protect the tiny pupfish and desert tortoise and stinginess over the region's rarest resource: water.

Water is the cooling agent for what traditionally has been the most cost-efficient type of large-scale solar plants. To some solar companies answering Washington's push for renewable energy on vast government lands, it's also an environmental thorn. The unusual collision pits natural resources protections against President Barack Obama's plans to produce more environmentally friendly energy.

The solar hopefuls are encountering overtaxed aquifers and a legendary legacy of Western water wars and legal and regulatory scuffles. Some are moving to more costly air-cooled technology — which uses 90 percent less water — for solar plants that will employ miles of sun-reflecting mirrors across the Western deserts. Others see market advantages in solar dish or photovoltaic technologies that don't require steam engines and cooling water and that are becoming more economically competitive.
