    Taiwan's Feng Chia University has succeeded in boosting the production of hydrogen from biomass to 15 liters per hour, one of the world's highest biohydrogen production rates, a researcher at the university said Friday. The research team managed to produce hydrogen and carbon dioxide (which can be captured and stored) from the fermentation of different strains of anaerobes in a sugar cane-based liquefied mixture. The highest yield was obtained by the Clostridium bacterium. Taiwan News - November 14, 2008.

Fuel testing shows biobutanol performance similar to unleaded gasoline

New fuel testing results shared today by DuPont and BP indicate that biobutanol has proven to perform similarly to unleaded gasoline on key parameters, based on ongoing laboratory- based engine testing and limited fleet testing.

At the Society of Automotive Engineers (SAE) world congress in Detroit, BP Biofuels program manager Frank Gerry and DuPont Biofuels venture manager David Anton told automotive industry value chain participants about the opportunities for biofuels to provide sustainable mobility solutions. They also addressed the science behind biobutanol, an advanced biofuel being jointly developed by BP and DuPont.

In 2006, the companies announced their joint strategy to deliver advanced biofuels that help meet increasing global demand for renewable transportation fuels, leveraging DuPont's advanced biotechnology capabilities and BP's fuel marketing and technology expertise. The first product targeted for introduction will be biobutanol (earlier post).
"Biobutanol addresses market demand for fuels that can be produced from domestic renewable resources in high volume and at reasonable cost; fuels that can be used in existing vehicles and existing infrastructure; fuels that offer good value to consumers; and fuels that meet the evolving demands of vehicles." - Frank Gerry, BP Biofuels program manager
Gerry spoke about results of tests that confirm biobutanol is a desirable fuel component. According to Gerry, biobutanol formulations that meet key characteristics of a "good" fuel include high energy density, controlled volatility, sufficient octane and low levels of impurities. He described early phase testing data that indicate that biobutanol fuel blends at a nominal 10 volume percent level perform very similarly to unleaded gasoline fuel. Additionally, the energy density of biobutanol is closer to unleaded gasoline (table, click to enlarge):

Fuel testing also has proven that biobutanol does not phase separate in the presence of water, and has no negative impact on elastomer swelling.

Anton spoke about DuPont's development of the new biobutanol technology. "Over 100 DuPont scientists and engineers are committed to making advanced biofuels and new energy-efficient biofuels processes a reality," he said. "Our researchers are working with BP scientists and are on track to deliver a higher yielding biobutanol technology." Anton outlined DuPont's three-pronged biofuels strategy which includes biobutanol, cellulosic fuels and seed/crop protection solutions.
