ClearEdge natural gas powered fuel cells CHP option for homes, small commercial

ClearEdge Power produces and maintains its natural gas powered distributed power fuel cell as a combined heat and power solution. Small and efficient, the system is an alternative to solar PV is size and cost. The downside is its dependence on natural gas.
Below are a few FAQs from their website

www.clearedgepower.com

Will the CE5 interfere with the building design?
In many situations, efficiency often trump looks when it comes to being green. With the CE5, you can offer clients both. The sleek design, compact size and color options of the unit will add, rather than deter from a building’s installed systems. Measuring 2’ (D) x 3’ (W) x 5’ (H), the CE5 fits either in an inside mechanical room or outside the home or business, discreetly sited to fit any building's design.

How much does the CE5 cost?
The list price for the CE5 is comparable to residential solar PV systems on a dollar per watt-installed basis. One advantage over solar, the CE5 generates eight times more energy than the same size solar installation. So, for the same capital investment, the CE5 gives you 80 MWh of annual combined electricity and heat, compared to approximately 10MWh generated by a 5kW solar system.

Operating costs for the CE5 are as low as 6.0¢ per kWh based on $1.20 per therm for natural gas, assuming full electrical and heat load utilization. The purchase price of the CE5 also includes a five-year EnergyPlus™ Service Agreement for all installation, parts and maintenance.

What are the long range benefits?
Po
wer represents a fundamental shift in the sourcing of energy. Ultimately, networks of micro-CHPs will be deployed within communities and business parks to provide self-generated base load energy, centrally controlled to send unused electricity back into the overtaxed grids as peak power on demand. This "distributed" approach secures and increases power generating capacity without adding new power plants and transmission lines.

ClearEdge Power applauds the City of Palm Desert, which Thursday becomes the first city in the country to provide residents with low-cost loans for energy-efficiency home improvements. The groundbreaking financing program is good news for homeowners, and for a number of companies throughout Southern California which provide alternative, clean energy technologies.
“The City of Palm Desert has essentially made it much easier for a larger number of residents and businesses to begin saving energy and money immediately, with very little investment up front,” says Bill Sproull, ClearEdge Power Senior Vice President, Business Development.

ClearEdge Power, a leading provider of ultra-clean and efficient on-site energy generation systems for homes and small businesses has been working with the City of Palm Desert, and supported the passage of Assembly Bill 811 (AB 811), which offers California cities a new way to help their citizens finance energy improvements. ClearEdge Power's CE5, a compact energy system that efficiently converts natural gas or propane into both electricity and heat, using clean fuel cell technology, will qualify for the Palm Desert Energy Independence Loan.

“ClearEdge Power has been working closely with the city of Palm Desert to understand and respond to the City's energy reduction goals. Alternative energy technologies, like the residential fuel cell energy systems, will go a long way toward helping the City achieve those goals,” says Pat Conlon, Palm Desert Energy Office Director. Conlon leads the City's ‘Set-to-Save' program, one of the most aggressive energy reduction initiatives in the country.

Home and business owners in the Coachella Valley currently pay some of the highest electricity rates in the country. Palm Desert's Energy Independence Loan Program and AB 811 will help in two significant ways: first, the initial capital cost investment for a new alternative energy system, like the CE5, will be spread over a multi-year loan term. Second, home and business owners will realize the cash and environmental savings from efficient energy systems from day one.

“We're essentially putting cash directly back into the pockets of homeowners and businesses while helping them reduce their overall energy consumption,” Sproull added.

The City of Palm Desert waived permitting fees, earlier this year, to encourage the installation of fuel cell systems. ClearEdge Power is working with architects, builders, home and business owners in the Coachella Valley and plans to begin the first local CE5 installations this fall.

About ClearEdge Power:
ClearEdge Power is a pioneer and leading provider of ultra-clean and efficient on-site energy generation systems for homes and small businesses. With operations throughout the West Coast of the United States, the company is positioned at the center of clean energy technology innovation and market adoption. Today, the company manufactures and markets the highly efficient CE5, a new energy solution that helps homes and businesses save money, reduce C02 emissions and maintain a comfortable lifestyle.

Precourt Institute for Energy Efficiency, Stanford Univ researches behavior, buildings, etc to improve energy efficiency

The Precourt Institute for Energy Efficiency
PRECOURT INSTITUTE FOR ENERGY EFFICIENCY
link to PEII website
Aug 15, 2008

PIEE was founded in October 2006 at Stanford University by a generous gift from Stanford Alumnus Jay Precourt.

As a Stanford University research institute, PIEE draws upon intellectual resources from the entire university. At the core of the Precourt Institute is an increasing number of faculty-led research teams including graduate and undergraduate students and post-doctoral fellows. Research teams include researchers and analysts from across the university, bringing expertise from many different disciplines.

What is the Precourt Institute's mission?
The mission of the Precourt Institute is to promote energy efficient technologies, systems, and practices, emphasizing economically attractive deployment. PIEE works to understand and overcome market, policy, technology, and human behavioral barriers to economically efficient reductions of energy use and to inform public and private policymaking. Energy Efficiency is vital for the U.S. and world economy, for environmental protection, and for energy security.

How will PIEE do this?
EducationThrough the funding of graduate students either as research assistants or to support their dissertation research, PIEE is facilitating the education of graduate students who choose to work within energy efficiency.

ResearchPIEE has six focus areas of energy efficiency research that we believe will help create workable options to promote energy efficiency. These clusters are:
» Buildings: commercial and residential building design, construction, operations, and embedded technologies, including building energy models and other design tools
» Transportation: technology and regulation of passenger cars and light duty trucks; transportation systems analysis; vehicle electrification
» Systems: systems analysis; electric generation/distribution systems, storage/distribution options, vehicle/building interactions
» Behavior: behavioral and decision making research, analysis, and intervention
» Energy Modeling: economic modeling of the energy system, institutions, and economic impacts, including process modeling of energy use
» Energy Policy: policy design, policy analysis, individual faculty advocacy; pricing policies, policy interventions, R&D policy

Conferences and WorkshopsPIEE convenes the annual Behavior, Energy, & Climate Change Conference, jointly with the California Institute for Energy Efficiency and ACEEE; the annual Energy Summit jointly with the Silicon Valley Leadership Group; an annual affiliates conference jointly with the Woods Institute for the Environment; and various workshops. These help assure that energy research is communicated broadly and that PIEE remains closely linked with industry, government, NGOs, and other research organizations.

Geothermal Power Erupts Worldwide, new tech expands options

WORLD GEOTHERMAL POWER GENERATION NEARING ERUPTION

Plan B Update
For Immediate Release


http://www.earthpolicy.org/Updates/2008/Update74.htm
Jonathan G. Dorn
With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth’s heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total electricity. In the first half of 2008, total world installed geothermal power capacity passed 10,000 megawatts and now produces enough electricity to meet the needs of 60 million people, roughly the population of the United Kingdom. In 2010, capacity could increase to 13,500 megawatts across 46 countries--equivalent to 27 coal-fired power plants.
Originating from the earth’s core and from the decay of naturally occurring isotopes such as those of uranium, thorium, and potassium, the heat energy in the uppermost six miles of the planet’s crust is vast--50,000 times greater than the energy content of all oil and natural gas resources. Chile, Peru, Mexico, the United States, Canada, Russia, China, Japan, the Philippines, Indonesia, and other countries along the Ring of Fire (an area of high volcanic activity encircling the basin of the Pacific Ocean) are rich in geothermal energy. Another geothermal hot spot is the Great Rift Valley of Africa, which includes such countries as Kenya and Ethiopia. Worldwide, 39 countries with a cumulative population of over 750 million people have geothermal resources sufficient to meet all their electricity needs. (See data at
www.earthpolicy.org/Updates/2008/Update74_data.htm.)
Typically, power generation using the earth’s heat required underground pockets of high-temperature water or steam to drive a steam turbine. Now, new technologies that use liquids with low boiling points in closed-loop heat exchange systems allow electricity to be generated at much lower temperatures. This breakthrough is making geothermal power generation viable in countries such as Germany that are not known for their geothermal resources and is one reason why the number of countries using the earth’s heat to generate electricity could almost double by 2010.
One advantage of geothermal power plants, beyond the benefit of producing electricity from a low-carbon, indigenous energy source with no fuel costs, is that they provide baseload power 24 hours a day. Storage or backup-power is not required.
The United States leads the world in generating electricity from the earth’s heat. As of August 2008, geothermal capacity in the United States totaled nearly 2,960 megawatts across seven states--Alaska, California, Hawaii, Idaho, Nevada, New Mexico, and Utah. California, with 2,555 megawatts of installed capacity--more than any country in the world--produces almost 5 percent of its electricity from geothermal energy. Most of this capacity is installed in an area called the Geysers, a geologically active region north of San Francisco.
Thanks to the Energy Policy Act of 2005, which made geothermal power generation eligible to receive the federal renewable energy production tax credit, electricity generated from geothermal resources now costs the same as fossil-fuel-based electricity in many markets in the western United States. With favorable economics, the geothermal industry is experiencing a surge in activity. As of August 2008, some 97 confirmed new geothermal power projects with up to 4,000 megawatts of capacity were under development in 13 states, with some 550 megawatts of this already in the construction phase. Expected to create 7,000 permanent full-time jobs, the new capacity will include numerous large-scale projects such as the 350-megawatt and 245-megawatt projects by Vulcan Power near Salt Wells and Aurora, Nevada; the 155-megawatt project by CalEnergy near the Salton Sea in southern California; and the 120-megawatt project by Davenport Power near the Newberry Volcano in Oregon.
Current development is only scratching the surface of what is possible. The U.S. Department of Energy estimates that with emerging low-temperature technologies, at least 260,000 megawatts of U.S. geothermal resources could be developed. A study led by the Massachusetts Institute of Technology indicates that an investment of roughly $1 billion in geothermal research and development over 15 years (roughly the cost of a single new coal-fired power plant) could lead to commercial deployment of 100,000 megawatts by 2050.
In Europe, the top countries in geothermal energy development are Italy with 810 megawatts and Iceland with 420 megawatts. Italy is expected to nearly double its installed capacity by 2020. Iceland, with 27 percent of its electricity needs met by harnessing the earth’s heat, is number one in the world in the share of its electricity generated from geothermal energy. Germany, with only 8 megawatts of installed capacity, lags behind but is beginning to see the effects of a feed-in tariff of €0.15 (US $0.23) per kilowatt-hour that was implemented in 2004. Almost 150 plants are now in the pipeline in Germany, with most of the activity centered in Bavaria.
Ten of the top 15 countries producing geothermal electricity are in the developing world. The Philippines, which generates 23 percent of its electricity from geothermal energy, is the world’s second biggest producer behind the United States. The Philippines aims to increase its installed geothermal capacity by 2013 by more than 60 percent, to 3,130 megawatts. Indonesia, the world’s third largest producer, has even bigger plans, calling for 6,870 megawatts of new geothermal capacity to be developed over the next 10 years--equal to nearly 30 percent of its current electricity generating capacity from all sources. Pertamina, the Indonesian state petroleum company, anticipates building most of this new capacity--adding its name to the list of conventional energy companies that are beginning to diversify into the renewable energy market.
The geothermal development potential of the Great Rift Valley in Africa is enormous. Kenya is the frontrunner in the effort to tap this potential. In late June 2008, President Mwai Kibaki announced a plan to install some 1,700 megawatts of new geothermal capacity within 10 years--13 times greater than the current capacity and one-and-a-half times greater than the country’s total electricity generating capacity from all sources. Djibouti, aided by Reykjavik Energy Invest’s commitment to provide $150 million for geothermal energy projects in Africa, aims to tap the earth’s heat to produce nearly all of its electricity within the next few years. Further stimulating development is the African Rift Geothermal Development Facility (ARGeo), an international organization partly funded by the World Bank that seeks to increase the use of geothermal energy in the Great Rift Valley by protecting investors from losses during early stages of development.
Industry, which accounts for more than 30 percent of world energy consumption, is also starting to turn to reliable, low-cost geothermal energy. In Papua New Guinea, a 56-megawatt geothermal power station owned by Lihir Gold Limited, a leading global gold company, meets 75 percent of corporate power demand at a notably lower cost than oil-fired power generation. In Iceland, five geothermal power plants planned near Reykjavik, which are slated to have a total capacity of 225 megawatts when completed in 2012, will provide electricity to new aluminum refineries.
Despite development potential measured in the hundreds of thousands of megawatts, tapping this renewable source of power is still in its infancy. But as more and more national leaders begin to see renewable energy as a cost-effective, low-carbon alternative to price-volatile, carbon-intensive fossil fuels, geothermal power generation is expected to move rapidly from marginal to mainstream.

Hundreds sign up for Palm Desert energy financing

Hundreds await energy loan program
K Kaufmann • The Desert Sun •
August 18, 2008
Link to original article

Palm Desert has 43 million kilowatt hours down, only 171 million more to go.

As of July, the city is one-fifth of the way toward its ambitious five-year goal to cut energy use by 30 percent.
And with officials working out the final details of a ground-breaking program to provide residents with low-interest loans for big-ticket energy savers, such as high-efficiency air conditioners and solar panels, those 171 kilowatt hours could be well within reach.
“I'm thrilled with the passage of (Assembly Bill) 811,” said Jim Hodge, project manager for Southern California Edison, which is partnering with Palm Desert on the five-year campaign.
“Once this loan program is officially introduced to the community, we're going to see a spike in our results, a sustained spike,” said Hodge, who announced the July figures on Friday.
AB 811 is the Palm Desert-sponsored bill, signed into law last month by Gov. Arnold Schwarzenegger, that will allow cities across the state to offer residents low-interest loans for energy-efficient home improvements, with a long-term payback plan tied to their property taxes.
The law, and Palm Desert's program — which will be the first in the state to take advantage of it — are drawing intense interest and anticipation from residents, businesses, and city and state government officials.
The Palm Desert City Council won't be voting on a resolution to set up its loan program — dubbed the “Energy Independence Program” — until Aug. 28, but that hasn't stopped about 235 residents from joining the waiting list for applications.
“It's a great idea,” said Maggie McLennon, who lives on California Street in one of the first houses built at Palm Desert Country Club in the 1960s.
McLennon wants a loan to replace an old clunker of an air conditioner that keeps her summer electric bills around $400 a month, she said.
“I wanted to finish upgrading the house, and if the city is willing to help with those things, why not?” she said.
Local and national businesses also are lining up to cash in on the program.
SunWize Technologies, a New York-based solar company with offices in Palm Desert, has beefed up its staff in anticipation of a sales surge sparked by the loan program, said Dave Holt, the company's marketing manager.
“It will allow more homeowners the ability to add solar electric to their homes,” Holt said. “The issue of having solar sometimes is the financial constraint. This will ease that and make it a lot easier for average homeowners to have solar.”
SunWize is planning weekend forums where homeowners will be able to get information on solar and the loan program, he said.
Vincent Battaglia, president of Renova, a Palm Desert solar company, also believes consumer education will be key and is moving fast to establish an AB 811 Web site that, he said, will be a clearing house for information on the law and Palm Desert's loan program.
“Nobody, no other state or federal entity, has ever taken this kind of step to bring in private money and marry it to citizens' interest in renewable energy,” Battaglia said. “Residential installation for solar and for new air conditioners is going to go through the roof.”
Palm Desert will also have a Web site for its loan program where other cities will be able to download model resolutions, application forms and other documents to customize for their own use.
“We wanted to give them a head start,” said Patrick Conlon, director of energy management.
They'll have “the ability to download Word files that can be altered” for their needs.
“I think it's a win-win-win for everybody,” said Gary Calhoun, recycling coordinator for Palm Springs, where officials are reviewing the law and waiting to see how Palm Desert sets up its program.
“It's a win for the residents; it's a win for the community at large and society because of the savings you would realize in consequent improvement in greenhouse gases,” he said.
“I think it has potential,” said Carol-Ann Coates, a building engineer with the city of Burbank, which like Palm Desert has a significant stock of older houses.
“It's a possibility to help people make these new green building' improvements, Coates said. “We'll keep an eye on it.”
State energy officials like Michael Peevey, president of the California Public Utilities Commission, would like to see AB 811 programs go statewide, with the Coachella Valley becoming an incubator.
“I hope they can proselytize and it can become a very active statewide program,” Peevey said. “The communities can join together through joint powers (so) you don't have to have each small community trying to do it own their own.”
The Coachella Valley Association of Governments is ready to step in as a potential coordinator for that effort, helping other desert cites set up programs, said executive director John Wohlmuth, who recently returned from an international energy conservation conference in Norway, where AB 811 was a major topic.
Wohlmuth sees a big pay-off for the valley, with energy financing programs creating a market that will draw still more clean, green business to the desert.
“Whether it's a pool pump or an air conditioner or a solar system, the penetration rate on getting these on homes (will be) higher in Palm Desert and the Coachella Valley,” he said. “If the penetration rate is there, it could be an economic development opportunity for the valley.”
How it works
Under Assembly Bill 811, cities can finance low-interest loans to residents for energy-efficient upgrades on their homes. The loans could be used only for improvements such as solar panels or air conditioners that stay with the house.A hypothetical case provided by EcoMotion, the consultants helping Palm Desert set up its Energy Independence Program: A resident with a 2,000 square-foot home wants to replace a low-efficiency, SEER 6 air conditioner with a high-efficiency, SEER 17 unit, which costs around $12,000.The resident can get a $1,000 rebate from Southern California Edison under Palm Desert's Set to Save Program and gets a $11,000 loan from the city's Energy Independence Program. The term on the loan is 6 percent for 10 years. Loan repayments are $740 every six months, or about $123 per month, but projected savings on electric bills are about $187 per month — a net saving of $64 per month.Once the loan is paid back, savings on energy bills over a 25-year period are estimated at $100,000.

Gov. Schwarzenegger Signs “Berkeley Bill” Enabling California Cities to Offer Solar and Energy Efficiency Loans

From - Flex Your Power Energy News
August 6, 2008
With passage of AB 811, California cities and counties have the green light to offer low-interest loans for solar panels and energy-efficiency improvements (Photo: Flickr)

Gov. Schwarzenegger recently signed Assembly Bill 811, giving all California cities and counties the ability to offer low-interest loans for energy-efficiency projects and solar panels to homeowners and small businesses. Residents would pay back the loans through assessments on property tax bills; if they move, the outstanding loan balance is taken over by the new owner. Without the law, some California cities might not have been able to offer the loans for solar panels and efficiency improvements such as insulation, double-paned windows and efficient HVAC systems. While “charter cities” such as Berkeley and San Francisco have supreme authority over municipal affairs, California’s 370 “general law cities” are bound by state laws that might have been prohibitive.

AB 811 was inspired, in part, by a program proposed by Cisco DeVries, chief of staff for Berkeley Mayor Tom Bates, in October of last year (e-Newswire, 10/31/07). For cities interested in developing a loan program, there are a variety of funding options, including using their general fund, issuing municipal bonds or partnering with a utility to get financing, Alex Traverso, a spokesperson for Assemblyman Lloyd Levine, author of AB 811, told Greentech Media. California cities are already racing to be the first to issue the low-interest loans. Berkeley’s effort, called “Berkeley FIRST,” is in the pilot stage. Palm Desert, meanwhile, which is working toward a goal of reducing citywide energy consumption by 30% by 2011 (Power Plug, 4/04/08), has already started a list of interested residents. The city plans to provide loans for as little as $5,000, with no upper limit, for energy-efficiency measures and installation of solar panels.

Berkeley to Finance Solar Installations
August 7, 2008

The city will pay upfront costs, which property owners will pay back in taxes. Will the program compete with companies that make a business of bankrolling installations in exchange for power-purchase agreements from customers?
Bullet Arrow November 8, 2007

Berkeley, Calif., this week approved a loan program to pay the upfront costs of installing solar power in businesses and residences in the city.

In exchange, property owners -- who also would own the solar-power systems -- would pay back the loan over 20 years as part of their property taxes, but in the meantime should be paying lower electric bills.

Although the Berkeley City Council approved the program Tuesday evening, city staff is still figuring out how the program will work, and the City Council will have to approve the financial and legal details before it takes effect.

"Berkeley actually is taking action and doing something that everybody thinks about," said John Woolard, CEO of BrightSource Energy, a company developing technology that uses the sun's heat instead of its light to produce electricity in utility-scale projects. The company has no apparent stake in Berkeley's plan.

"There is a different model than just the utilities buying power, and it's going to be fascinating to watch. Berkeley has been bold in taking the first step."

The city claims it's the first in the nation to approve such a program.

While that may be true, the idea behind the program isn't a Berkeley original.

Companies such as SunEdison, MMA Renewable Ventures and Recurrent Energy have been paying installation costs in exchange for agreements that commercial customers will buy the power. And companies such as Sun Run Generation do the same for residential customers.

Such companies coordinate financings with major corporations that can take advantage of the tax benefits of owning solar installations.

But government agencies have the advantage of being able to tap into tax-exempt, low-interest financing such as bonds, potentially cutting costs in half compared to commercially financed installations, said Paul Fenn, CEO of Local Power, which helps government agencies set up renewable-energy programs.

"It's such a huge advantage," he said. "The cost of capital is dramatically lower. If you capture the 20-year payback of a bond, it has a dramatic effect on the cost of a facility."

Some companies think Berkeley's program might not be such a good idea.

"I'm unsure if the program in Berkeley is a good deal at all, considering that solar systems are not subject to property tax in California and that accepting this proposal seems to void that benefit to homeowners," said MMA Renewable Ventures CEO Matt Cheney, who added it's unclear if the property tax will drop after the solar-power system is paid off.

"While we applaud the efforts to support solar, I think a better approach might be for the city of Berkeley to support clean-energy options for its residents that are readily available today from its local financial institutions through providing property tax relief or loan guarantees."

In any case, Fenn said other cities are already trying ideas similar to Berkeley's.

San Francisco and several cities in Massachusetts and Ohio already are working on programs to pay upfront solar-power costs for their residents using bond money, which residents pay back as part of their electric bills, Fenn said.

San Francisco has raised bond money for such a system, and in June, the city said it planned to roll out 360 megawatts worth of solar-power, wind-power and energy-management projects as part of the program.

Fenn said municipal financings of renewable-energy technologies have been growing over the past seven years as cities try different ways to encourage cleaner energy.

He gave an example: Berkeley already has set a goal of getting 51 percent of its energy from renewable sources by 2017. As part of the plan to reach that goal, the city plans to partner with nearby cities Oakland and Emeryville to buy renewable energy using money raised in bonds.

All these community-choice aggregations also will offer residents the opportunity own solar-power projects essentially on layaway, with no money down, and then pay back the installation costs as part of their electricity bills, Fenn said.

And renewable-energy installations also are exempt from federal taxes, so residents that agree to pay the extra charge -- both on electricity bills, in the case of aggregations, and on property taxes, in the case Berkeley's new program -- would be able to then exempt those charges from federal taxes, he said.

Fenn and Woolard both said they expect to see more programs like Berkeley's catch on.

But if they do, it also could mean the role of companies that finance projects in exchange for power-purchase agreements will shift, Fenn said.

"It influences them in terms of how they should plan for future markets," he said. "Public financing could be viewed as competition because the government is coming in, but I believe that would be a strategic mistake.

"Those companies that adapt to the market and shift to [add value by] participating in those programs will win; those that try to compete against them will lose."

CAMBRIDGE, Massachusetts (Reuters) -
A U.S. scientist has developed a new way of powering fuel cells that could make it practical for home owners to store solar energy and produce electricity to run lights and appliances at night.
A new catalyst produces the oxygen and hydrogen that fuel cells use to generate electricity, while using far less energy than current methods.
With this catalyst, users could rely on electricity produced by photovoltaic solar cells to power the process that produces the fuel, said the Massachusetts Institute of Technology professor who developed the new material.
"If you can only have energy when the sun is shining, you're in deep trouble. And that's why, in my opinion, photovoltaics haven't penetrated the market," Daniel Nocera, an MIT professor of energy, said in an interview at his Cambridge, Massachusetts, office. "If I could provide a storage mechanism, then I make energy 24/7 and then we can start talking about solar."
Solar has been growing as a power source in the United States -- last year the nation's solar capacity rose 45 percent to 750 megawatts. But it is still a tiny power source, producing enough energy to meet the needs of about 600,000 typical homes, and only while the sun is shining, according to data from the Solar Energy Industries Association.
Most U.S. homes with solar panels feed electricity into the power grid during the day, but have to draw back from the grid at night. Nocera said his development would allow homeowners to bank solar energy as hydrogen and oxygen, which a fuel cell could use to produce electricity when the sun was not shining.
"I can turn sunlight into a chemical fuel, now I can use photovoltaics at night," said Nocera, who explained the discovery in a paper written with
Matthew Kanan published on Thursday in the journal Science.
Companies including United Technologies Corp produce fuel cells for use in industrial sites and on buses. Automakers including General Motors Corp and Honda Motor Co are testing small fleets of fuel-cell powered vehicles.

POTENTIAL FOR CLEAN ENERGY
Fuel cells are appealing because they produce electricity without generating the greenhouse gases associated with global climate change. But producing the hydrogen and oxygen they run on typically requires burning fossil fuels.
That has prompted researchers to look into cleaner ways of powering fuel cells. Another researcher working at Princeton University last year developed a way of using bacteria that feed on vinegar and waste water to generate hydrogen, with minimal electrical input.
James Barber, a biochemistry professor at London's Imperial College, said in a statement Nocera's work "opens up the door for developing new technologies for energy production, thus reducing our dependence on fossil fuels and addressing the global climate change problem."
Nocera's catalyst is made from cobalt, phosphate and an electrode that produces oxygen from water by using 90 percent less electricity than current methods, which use the costly metal platinum.
The system still relies on platinum to produce hydrogen -- the other element that makes up water.
"On the hydrogen side, platinum works well," Nocera said. "On the oxygen side ... it doesn't work well and you have to put way more energy in than needed to get the (oxygen) out."

Current methods of producing hydrogen and oxygen for fuel cells operate in a highly corrosive environment, Nocera said, meaning the entire reaction must be carried out in an expensive highly-engineered container.
But at MIT this week, the reaction was going on in an open glass container about the size of two shot glasses that researchers manipulated with their bare hands, with no heavy safety gloves or goggles.
"It's cheap, it's efficient, it's highly manufacturable, it's incredibly tolerant of impurity and it's from earth-abundant stuff," Nocera explained.
Nocera has not tried to construct a full-sized version of the system, but suggested that the technologies to bring this into a typical home could be ready in less than a decade.

The idea, which he has been working on for 25 years, came from reflecting on the way plants store the sun's energy.
"For the last six months, driving home, I've been looking at leaves, and saying, 'I own you guys now,'" Nocera said.

~ JFF - AB 811 Implimentation: Berkeley - Short status from Modern Earth

Spoke with Nils Moe of Berkeley mayor office. In their pilot they will focus on solar pv only but require homes to meet RICO(?) standards. In the general rollout they will offer a bundle of solar, energy efficiency improvements and solar water. They are in negotiations with lenders to front the funds for the projects.
