Honda Introduces Fuel Cell for Below-Freezing Temperatures
Honda Motor Co., Ltd. has tackled one of the largest technical barriers for fuel cell vehicles, producing a fuel cell with advanced electrolyte membranes that can operate at temperatures as low as 4 degrees Fahrenheit below zero (negative 20 degrees Celsius). Honda announced last week that the new fuel cell uses a simplified structure to cut the number of components by nearly half, while more than doubling the power output per pound of fuel cell, compared to Honda’s previous-generation fuel cell. Incorporating the new fuel cell into Honda’s fuel cell vehicle, the FCX, yields a 10-percent increase in fuel efficiency and a 20-mile increase in range, to more than 180 miles. Honda delivered the first of five FCX vehicles to the City of Los Angeles in December 2002; last month, Honda also agreed
to deliver two FCX vehicles to the City of San Francisco by year-end.
Honda has also developed an experimental “Home Energy Station” that converts natural gas into hydrogen, which is then purified, compressed, and stored. The hydrogen can be used either to fuel a fuel cell vehicle or to supply a stationary fuel cell — incorporated in the unit — to produce electricity and hot water. In addition, Honda has developed a new Ruthenium-based catalyst that allows water to be converted into its components, hydrogen and oxygen, more efficiently. Honda has built a water electrolysis unit that uses power from an advanced solar cell to generate hydrogen and has added the unit to its hydrogen production station in Torrington, California.

For the record, General Motors Corporation (GM) announced a similar cold-start fuel cell achievement back in September 1999, although it is not clear if the company ever incorporated that fuel cell into a vehicle. See the GM press release: [sorry this link is no longer available]
Other car companies continue to make progress on fuel cell vehicles. In late September, Toyota delivered two more fuel cell vehicles to University of California campuses — one to Irvine and one to Davis. Mitsubishi Motors Corporation has also built a fuel-cell vehicle based on a minivan and using a fuel cell from Ballard Power System Inc. Closer to home, Ford Motor Company is planning to test its Ford Focus fuel cell vehicle on the streets of Vancouver, British Columbia, next year.

California and Ohio Support Distributed Generation Projects
Two recent actions in the states of California and Ohio will help groups and individuals generate their own power on-site, a concept known as “self-generation” or “distributed generation.” The actions bode particularly well for solar power installations in the two states.
In California, outgoing Governor Gray Davis signed legislation on Sunday that will extend the state’s Self-Generation Incentive Program through the end of 2007. The program has been critical to the growth of solar power in the state, and was set to expire at the end of 2004. The new legislation, Assembly Bill 1685, also sets emissions standards
and requires a minimum conversion efficiency of 60 percent for any fossil-fueled distributed generation that seeks to qualify for the incentive payment. Combined heat and power projects can earn credits against the emission standards based on how much heat they recover. See the governor’s October 12th press release, titled “Legislative
Update — Part III,” by selecting “Press Releases” on the governor’s Web site at:

Governor Davis faced a deadline of midnight on Sunday to either sign or veto 282 bills that awaited his signature; any bills that he didn’t sign or veto would automatically become law. For detailed information about Assembly Bill 1685, enter “AB 1685” in the search box on the Official California Legislative Information Web site at:
In Ohio, the Department of Development has awarded a total of $924,019 in grants to 26 distributed generation projects throughout the state. The projects cover a wide range of technologies to be installed in both homes and business, including solar power systems, solar thermal systems, wind turbines, a biomass-to-energy system, a gas turbine, and a reciprocating engine. Many of the projects involve “hybrid” systems that combine two or more of the technologies, and several make use of waste heat produced by the electrical generators. But perhaps the most
interesting award is to the City of Cleveland, which plans to install a 530-kilowatt solar power system at one of its water treatment plants. If built, it will be the largest solar power system in
the Midwest. See the Ohio Department of Development press release: [sorry this link is no longer available]

Aside from financing, the trickiest parts of installing distributed generation usually involve agreements with the local utility, including agreements on how to connect to the grid — referred to as “interconnection” — and on how the utility will credit the owner for any power fed into the grid. Advocates of distributed generation prefer a “net metering” agreement that credits power fed into the grid against power drawn from the grid, requiring the owner to only pay the
net difference. To help advance distributed generation, the Interstate Renewable Energy Council (IREC) recently released new model rules to help guide policymakers considering net metering or interconnection rules in their states.

Solar-Powered LED Lamps Help Guide Air Force Jets in Iraq
Solar power may still conjure images of hippies and hot tubs among some people, but its current use by the U.S. Air Force adds a level of machismo that should help to dispel that image. Solar-powered lights are now marking runways at the U.S. Air Force base in Kirkuk, Iraq, and will soon be used to mark obstructions and a helipad perimeter at the base. Carmanah Technologies Corporation, which had already provided 400 solar-powered lights to the base, announced in early October that it received an order for 120 more lights. The second order is a vote of confidence for the solar technology, which uses energy-efficient light-emitting diodes, or LEDs, as a light source.
More than 2,600 of the solar lights are now being used at military airfields throughout the world. See the Carmanah press release: [sorry this link is no longer available]
Companies continue to make advancements in LED lighting, opening up new opportunities for their use in everyday applications. Lumileds Lighting, for instance, has just released the Luxeon III light source, which uses LEDs to produce up to 80 lumens of white light while consuming about 3.9 watts of power. That’s still fewer lumens per watt
than most compact fluorescent lights, but more energy-efficient than an incandescent light. For instance, a 60-watt incandescent bulb typically produces about 900 lumens, or about 15 lumens per watt, compared to 20.5 lumens per watt for the Luxeon III LED light. Lumileds has recently seen its lights used for concert and dance-floor lighting, headlights in concept cars, and even headlights and taillights on Amish buggies. See the Lumileds Luxeon Web page and press release page: [sorry this link is no longer available]

Universal Display Corporation is taking an alternative approach, forming LEDs from organic materials. The company announced last week that it received a $750,000 award from DOE to advance its development
of a 6-inch square panel made of thin films of organic LED materials that emit white light. See the company’s press release: [sorry this link is no longer available]
Australia’s “World Solar Challenge” Car Race Starts Sunday
The seventh annual “World Solar Challenge” kicks off in Darwin, Australia, on Sunday, October 19th. Race organizers announced on Tuesday that 23 solar cars from 10 countries have entered the race, which runs 1,870 miles (3,010 kilometers) down the center of the Australian continent, ending in Adelaide on October 28th. Unlike the
American Solar Challenge, which is divided into four stages, the World Solar Challenge is run in one stage. That allows the teams to travel as far as they can each day, although they must stop by 5 p.m. Apart from compulsory stops at seven checkpoints, the teams are on their own in the Australian outback.

Tests of Tidal Energy Turbine Underway in the United Kingdom
Sea Power International AB announced in September that it was starting tests of its prototype tidal energy turbine near the shore of Shetland, in the far northern reaches of the United Kingdom. The turbine will be attached to a ship that will be anchored at 10 sites in the Bluemull Sound, located between the islands of Yell and Unst. The test will determine the best site to locate a full-scale tidal power station. According to the company, the prototype tidal energy
turbine is based on an existing wind turbine design. See the Sea Power press release at: http://www.seapower.se/presseng.htm
Meanwhile, the Wave Dragon wave energy system continues to press ahead at its test site in the Danish fjord called Nissum Bredning. In September, Wave Dragon added six turbines to the wave energy system, bringing the total to seven. So far, there’s no word from the company on the amount of power being produced by the prototype system. See the Wave Dragon press release: [sorry this link is no longer available]
Seattle Bank Offers Mortgage Financing for Energy Efficiency
Energy-efficient products nearly always pay for themselves — often in a short period of time — but when new homeowners are out buying appliances, the price premium on the high-efficiency models often leads them to buy the less-expensive model that will cost them more in the long run. In an attempt to overcome that shortsighted view,
HomeStreet Bank and the Efficiency Services Group (ESG) are now offering homeowners a way to use their mortgage to finance energy efficiency improvements. Through the “Mortgage Options for Resource Efficiency” (MORE) program, homeowners can add $4,000 to their mortgage, which is placed in an escrow account. An energy specialist from ESG, a division of Portland General Electric, will then perform an energy analysis to determine which upgrades make
the most sense. The homeowner can then choose from a menu of energy-efficiency options, including lighting, appliances, water-saving devices, and weatherization measures. Unused funds are applied to the pay the principal on the mortgage. See the September 11th press release on the

EIA Statistics: Newer Homes Tend to Use More Energy
Despite an ever-expanding menu of energy-efficient building technologies, including better methods of sealing out air leaks, improved insulation, high-tech windows, and other advances, DOE statistics show that newer U.S. homes still tend to use more energy than older ones. According to a recent tabulation of residential energy use statistics by DOE’s Energy Information Administration (EIA), homes built between 1990 and 2001 consume, on average,
92.7 million Btu (British thermal units) of energy per year, which is higher than the average energy use in homes built in the previous three decades. Only homes built before 1960 show a higher average energy use than their 1990s counterparts. Two factors may help explain the trend: first, newer homes tend to be larger than older homes, and second, the owners of the newer homes tend to have higher incomes than owners of older homes, which may lead them to conserve less or to buy more energy-using devices. See the EIA’s 2001 Residential Energy
Consumption Survey: [sorry this link is no longer available]
How much energy should we expect a new home to use? How about zero? It may sound far-fetched, but DOE’s Zero Energy Homes research initiative is proving it can be done. See the initiative on the DOE Building Technologies Program Web site: [sorry this link is no longer available]
