GreenFuel Technologies Corporation: 2004 spinoff from a space technology company, attempting conversion of emissions to usable biomass (i.e. algae) in novel bioreactors: "Depending on customer specifications, GreenFuel will reduce up to 90% of NOx and 40% of CO2, generating biomass, emissions reduction credits, and public goodwill, for far less than the price of current Selective Catalytic Reduction systems or CO2 sequestration methods, and with no toxic byproducts." Innovations are outlined. Field test is underway on MIT's cogen power plant. 11:02:26 PM
Intelligent Energy Demonstrates Fuel Cell for Rural Electrification in Latin America: "Intelligent Energy Inc. says it has completed trials of its ethanol-based fuel cell technology system, showing that sufficient electricity can be generated for a rural home from equipment little larger than a shoebox, using fuel derived from sugar cane. ..
Intelligent Energy is engaged in a partner program in Argentina, Brazil and Mexico which is focused on providing rural and urban electricity solutions. Dr. Eduardo Torres Serra of CEPEL, Brazil's premier energy research laboratory, which is currently engaged in research aimed at rural and peri-urban electrification, witnessed the operation of Intelligent Energy's fully integrated ethanol-in to electricity-out system. He commented: "The Intelligent Energy system is at the cutting edge of technology, it is very compact and extremely impressive."
Making the announcement today, Intelligent Energy's Chairman, former Chairman of Shell, Sir John Jennings, said: "This successful demonstration is an important part of our expanding strategy to accelerate market acceptance of fuel cell technology as an alternative power source. " The company has interesting people from the conventional energy business, and materials that emphasize developing countries. They appear to proceed by acquisition of companies with promising technology, from fuel source to power output. 10:47:40 PM
CO2 bioreactors: Mix power plant CO2 with water and feed it to algae. "As the carbon dioxide exhaust moves toward the smokestacks, it would pass through tubes of running water, creating bicarbonates that would bubble in the water like soda pop. The water then flows through a bioreactor that contains a series of screens on which algae grow. "The algae basically drink the bicarbonates," says David Bayless, who also serves as associate director of the [Ohio U]'s Ohio Coal Research Center. "They get carbon through this system much quicker than trying to get it out of the air." .. He estimates that an average-size plant using this technology could process 20 percent of its carbon dioxide emissions and produce 200,000 tons or more of algae per year for a secondary market." News story online. Most info dates from 2001, including a technical paper. 10:22:20 PM
Jatropha plant yields biodiesel: "DaimlerChrysler is launching a new public-private joint enterprise in India for the production of environment-friendly biodiesel that can be used to power Mercedes vehicles. .. The project is setting out to test the production of biodiesel from Jatropha plants on eroded ground and its preparation for subsequent use in internal combustion engines.
With the establishment of this plantation, wind erosion will be alleviated and the roots of the plants will help reduce water erosion. The biscuits created as a byproduct of the oil extraction make an excellent organic fertilizer that helps improve the quality of the soil. It is envisaged that the plantations will later be operated by the municipal authorities.
Jatropha biodiesel is characterized by particularly favorable ignition performance. It also contains no sulfur and is thus a clean, low-emission fuel. .. Jatropha grows wild in many areas of India and even thrives on infertile soil. A good crop can be obtained with little effort. "
The Austrian Biofuels Institute provided a note on a field test of the fuel in 2004, with some into on its development since 1996. 9:54:27 PM
New Solar Tent Prototypes for US Army (June 16, 2004)
: "Iowa Thin Film Technologies, Inc., has completed the development of integrated solar technology for three Army tent prototypes. The tents integrate the company's PowerFilm® flexible solar panels directly with the tent fabric. Iowa Thin Film Technologies says that it is the only company in the world that has developed this fabric integration solar technology." Could be equally useful during disasters or in refugee camps. 9:47:55 PM
New Transmission Line for CA Wind: "A new transmission project designed to carry wind energy from California's Tehachapi and Antelope Valley area to customers throughout California met with swift approval from the California Independent System Operator Board of Governors. The new line is needed to carry power from an expansion of wind turbine generators planned for the area. The Tehachapi range already is home to more than 600 MW of wind generation, making it California's largest concentration of wind turbines. As much as 1,100 MW worth of new wind projects are planned for the region.. California utilities [must] meet the state's Renewable Portfolio Standard, which requires 20 percent of the energy the Investor-Owned Utilities deliver to their customers to come from renewable resources by the year 2017. .. The 25-mile Antelope-Pardee line will cost about $94 million to build. It could be energized as early as December 2006. " 8:34:23 PM
