Hydrogen is the most abundant element in the universe, but turning it into a practical renewable fuel has long been a challenge for researchers. Producing it through the process of water-splitting has shown promise, but it requires finding a way to do so efficiently and inexpensively. One obstacle to this has been finding the right catalyst for the water-splitting process. Platinum has proved to work well, but it’s prohibitively costly, and researchers have been on the hunt for something cheaper.(more…)
*JBEI Researchers Develop a New Candidate for a Cleaner, Greener and Renewable Diesel Fuel*
A class of chemical compounds best known today for fragrance and flavor may one day provide the clean, green and renewable fuel with which truck and auto drivers fill their tanks. Researchers at the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI) have engineered Escherichia coli (E. coli) bacteria to generate significant quantities of methyl ketone compounds from glucose. In subsequent tests, these methyl ketones yielded high cetane numbers – a diesel fuel rating comparable to the octane number for gasoline – making them strong candidates for the production of advanced biofuels.
“Our findings add to the list of naturally occurring chemical compounds that could serve as biofuels, which means more flexibility and options for the biofuels industry,” says Harry Beller, a JBEI microbiologist who led this study. “We’re especially encouraged by our finding that it is possible to increase the methyl ketone titer production of E. coli more than 4,000-fold with a relatively small number of genetic modifications.” (more…)
EAST LANSING, Mich. — Many people are willing to pay a premium for ethanol, but not enough to justify the government mandate for the corn-based fuel, a Michigan State University economist argues.
Soren Anderson studied the demand for ethanol, or E85, in the United States. He found that when ethanol prices rose 10 cents per gallon, demand for ethanol fell only 12 percent to 16 percent on average. (more…)
