Blending more ethanol into fuel to cut air pollution from vehicles carries a hidden risk that toxic or even explosive gases may find their way into buildings, according to researchers at Rice University.

MIT chemical engineers have devised a cheaper way to synthesize a key biofuel component, which could make its industrial production much more cost-effective. The compound, known as gamma-valerolactone (GVL), is attractive because of its versatility, says Yuriy Román, an assistant professor of chemical engineering and leader of the research team. It has more energy than ethanol and could be used on its own or as an additive to other fuels. GVL could also be useful as a “green” solvent or a building block for creating renewable polymers from sustainable materials.

In the search for renewable alternatives to gasoline, heavy alcohols such as isobutanol are promising candidates. Not only do they contain more energy than ethanol, but they are also more compatible with existing gasoline-based infrastructure. For isobutanol to become practical, however, scientists need a way to reliably produce huge quantities of it from renewable sources.

Researchers seeking to improve production of ethanol from woody crops have a new resource in the form of an extensive molecular map of poplar tree proteins, published by a team from the Department of Energy's Oak Ridge National Laboratory.

A new study from the University of Illinois concludes that learning-by-doing, stimulated by increased ethanol production, played an important role in inducing technological progress in the corn ethanol industry. It also suggests that biofuel policies, which induced ethanol production beyond the free-market level, served to increase the competitiveness of the industry over time.

Almost 80 percent of current farmland in the U.S. would have to be devoted to raising corn for ethanol production in order to meet current biofuel production targets with existing technology, a new study has found. An alternative, according to a study in ACS’ journal Environmental Science & Technology, would be to convert 60 percent of existing rangeland to biofuels.
