...fake IDs—it is through these techniques that most Harvard students gain their appreciation and understanding of beer. But one group of freshman is taking a more scholarly approach to their alcohol education in the new freshman seminar, “Principles of Industrial Fermentation: Beer, Wine, Bioethanol, and Beyond...
Whatever the future of the electric car and bioethanol, the notion that America must end its oil habit is gaining currency in Washington. George W. Bush, the former Texan oilman, has begun talking up corn ethanol and clean diesel and has endorsed a $4,000 tax credit for purchases of hybrid cars. That has not gone unnoticed by energy's new coalition of convenience, even if the President hasn't yet mentioned plug-in hybrids or bioethanol. "We drive to high-tech jobs today in cars built with 100-year-old technology, using 100 million-year-old fuel," says Podesta...
...anti-oil coalitions talk about ethanol fueling the future car, they aren't talking about the brew distilled from cornstarch. What they are referring to is a more fiscally and environmentally defensible alcohol, brewed from prairie grasses or agricultural waste, like straw. Trouble is, the technology required to commercialize bioethanol is in its infancy...
Enzymes that help transform cornstarch into ethanol are fairly run-of-the-mill in biotech terms. The same can't be said of those needed to brew bioethanol from indigestible plant fibers. Making enzymes efficient and cheap enough for that has long been an obstacle to a viable bioethanol industry. Canada's Iogen is the only biotech firm to have shipped a batch of commercial bioethanol (see main story). But Novozymes is making waves as well. It announced in March that with $17 million in U.S. Department of Energy (DOE) funding, it had reduced the cost of enzymes for making...
...involved in this because we believe there is a market," says Riisgaard, though he thinks a large bioethanol industry is still years away. With more funds from the DOE, Novozymes will supply enzymes for a bioethanol plant to be built in Nebraska next year by a subsidiary of the Spanish firm Abengoa. More than a few people in Washington will be watching. --By Unmesh Kher. Reported by Ulla Plon/Copenhagen
