* German, Japan carmakers tout hydrogen fuel at D.C. summit
Washington,DC,USA -The Detroit News, by David Shepardson -June 19, 2012: -- German and Japanese automakers expressed optimism Tuesday about the prospects for hydrogen fuel-cell vehicles as the long-term solution to replacing vehicles that run on oil... At the Washington Fuel Cell Summit in Washington, advocates said the key issue is ensuring enough hydrogen fueling stations, and making sure they serve enough vehicles in a single day... Some stations currently can only fill six vehicles before they need to be refueled. But some stations can get larger tanks that could fuel up to 100 vehicles before needing to refilled... Automakers also must bring costs down for the technology dramatically... By the end of the year there should be eight stations in the Los Angeles area, up from five... By contrast, there are about 180,000 gas stations nationwide...
* New York / USA - Carbon is Key for Getting Algae to Pump Out More Oil

The findings — published online in the journal Plant and Cell Physiology on May 28, 2012 — may point to new ways to turn photosynthetic green algae into tiny “green factories” for producing raw materials for alternative fuels... “We are interested in algae because they grow very quickly and can efficiently convert carbon dioxide into carbon-chain molecules like starch and oils,” said Brookhaven biologist Changcheng Xu, the paper’s lead author. With eight times the energy density of starch, algal oil in particular could be an ideal raw material for making biodiesel and other renewable fuels...
