Biodiesel auf dem Vormarsch

2004 fast ein Drittel mehr verkauft

Die hohen Treibstoffpreise lassen immer mehr Verbraucher zum günstigeren Biodiesel greifen. Mit 476 Millionen Litern seien bereits im vergangenen Jahr 32 Prozent mehr als 2003 verkauft worden, teilte die Arbeitsgemeinschaft Qualitätsmanagement Biodiesel (AGQM) am Mittwoch in Berlin mit. Der Fiskus erhebt keine Mineralölsteuer auf Biodiesel, an der Tankstelle ist er derzeit im Schnitt um zehn Cent billiger als herkömmlicher Diesel-Treibstoff. Der Anteil am gesamten Dieselmarkt liegt nach AGQM-Angaben bei vier Prozent.

Mehr als die Hälfte des 2004 verkauften Biodiesel-Treibstoffs sei in Bayern gezapft worden. Die AGQM befragte 758 der rund 1950 deutschen Biodiesel-Tankstellen.

Academic Study Discredits Ethanol, Biodiesel
July 15, 2005


Ithaca, New York [RenewableEnergyAccess.com] We regularly report on biofuels -- from industrial ethanol facilities to home-brewed biodiesel -- because they're a big slice of the renewable energy pie. A new study from Cornell University and University of California-Berkeley directly challenges that, saying that turning plants such as corn, soybeans and sunflowers into fuel uses much more energy than the resulting ethanol or biodiesel generates.

"There is just no energy benefit to using plant biomass for liquid fuel,"

- David Pimentel, professor of ecology and agriculture at Cornell "There is just no energy benefit to using plant biomass for liquid fuel," says David Pimentel, professor of ecology and agriculture at Cornell. "These strategies are not sustainable."

Pimentel and Tad W. Patzek, professor of civil and environmental engineering at Berkeley, conducted a detailed analysis of the energy input-yield ratios of producing ethanol from corn, switch grass and wood biomass as well as for producing biodiesel from soybean and sunflower plants.

Their report is published in Natural Resources Research (Vol. 14:1, 65-76). In terms of energy output compared with energy input for ethanol production, the study found that: corn requires 29 percent more fossil energy than the fuel produced; switch grass requires 45 percent more fossil energy than the fuel produced; and wood biomass requires 57 percent more fossil energy than the fuel produced.

In terms of energy output compared with the energy input for biodiesel production, the study found that: soybean plants requires 27 percent more fossil energy than the fuel produced, and sunflower plants requires 118 percent more fossil energy than the fuel produced.

In assessing inputs, the researchers considered such factors as the energy used in producing the crop (including production of pesticides and fertilizer, running farm machinery and irrigating, grinding and transporting the crop) and in fermenting/distilling the ethanol from the water mix. Although additional costs are incurred, such as federal and state subsidies that are passed on to consumers and the costs associated with environmental pollution or degradation, these figures were not included in the analysis.

"The United State desperately needs a liquid fuel replacement for oil in the near future," says Pimentel, "but producing ethanol or biodiesel from plant biomass is going down the wrong road, because you use more energy to produce these fuels than you get out from the combustion of these products."

Although Pimentel advocates the use of burning biomass to produce thermal energy (to heat homes, for example), he deplores the use of biomass for liquid fuel.

"The government spends more than $3 billion a year to subsidize ethanol production when it does not provide a net energy balance or gain, is not a renewable energy source or an economical fuel," Pimentel said. "Further, its production and use contribute to air, water and soil pollution and global warming."

He points out that the vast majority of the subsidies do not go to farmers but to large ethanol-producing corporations.

"Ethanol production in the United States does not benefit the nation's energy security, its agriculture, economy or the environment," Pimentel said. "Ethanol production requires large fossil energy input, and therefore, it is contributing to oil and natural gas imports and U.S. deficits."

He says the country should instead focus its efforts on producing electrical energy from photovoltaic cells, wind power and burning biomass and producing fuel from hydrogen conversion.
