Algae: Lean, Green Biofuel?

(NEWSER) - Once considered a win-win for the environment and energy independence, America’s biofuel industry is sputtering to a halt, the Wall Street Journal reports. Thanks to the recession, lower oil prices, and government delays, two-thirds of American biodiesel refineries—dozens of plants—are idle, and companies across the country are shutting down. The crisis could scare investors away from newer technologies more promising than much-maligned corn-based ethanol. More»

From sawdust to agricultural waste, scientists drive toward new fuels

(NEWSER) - After decades of dreaming, schemes to turn waste into fuel are finally getting traction in the US, with some 28 plants in the works and a handful even up and running, the New York Times reports. They consume everything from wood chips to garbage, as once-prohibitively expensive processes become competitive with $4-a-gallon gasoline. “American innovation is going to come up with the solution,” one researcher tells the Times.

Next hurdle: bringing it to market

(NEWSER) - Algae-based fuel is a step closer to reality. Scientists in California have genetically modified a microbe so that it can convert seaweed into biofuel, the Guardian reports. "Natural seaweed species grow very fast—10 times faster than normal plants—and are full of sugars, but it has been very difficult to make ethanol by conventional fermentation," says a researcher. The microbe breakthrough is a "critical step" toward an alternative form of ethanol, but there's still a long way to go. More»

Corn-based fuel does little to help environment, he admits

(NEWSER) - Al Gore regrets supporting subsidies for corn-based ethanol when he was in office, he revealed during a speech in Athens yesterday, confessing that he’d done it more to bolster his presidential ambitions than to help the planet. “First generation ethanol I think was a mistake,” Gore said, according to Reuters , arguing that “it is not good policy to have these massive subsidies.” More»

Will partner with famed genome expert Craig Venter

(NEWSER) - Exxon Mobil, the biggest oil company in the world, will invest $600 million in turning algae into fuel, the New York Times reports. Known for blowing off concerns about global warming and dismissing biofuels—its CEO famously called ethanol “moonshine”—Exxon Mobil has in fact been researching alternative fuels for years, says a VP. The current plan involves a partnership with a biotech company founded by Craig Venter, known for his work on the human genome. More»
