Sentences with phrase «than the ethanol yields»

• Biodiesel production using soybean required 27 % more fossil energy than the biodiesel fuel produced (Note, the energy yield from soy oil per hectare is far lower than the ethanol yield from corn).

Not exact matches

Now, the first large - scale study shows that switchgrass yields more than five times the energy needed to grow, harvest, and transport the grass and convert it to ethanol.

That result contrasts sharply with a controversial study published just over a year ago in Science that suggested that a mixture of prairie grasses farmed with little fertilizer or other inputs would produce a higher net energy yield than ethanol produced from corn (Science, 8 December 2006, p. 1598).

Sunlight - illuminated particles can also drive H2O - ethanol distillation, yielding fractions significantly richer in ethanol content than simple thermal distillation.

However, the ethanol concentration yielded from a cellulosic ethanol process tends to be significantly lower than the concentration obtained in a conventional ethanol production.

Projects must demonstrate economically competitive yields and lower GHG potential than Low Carbon Fuel Standard (LCFS) pathways for corn ethanol or soy biodiesel.

The process is able to yield more than 100 gallons of ethanol per ton of dry biomass.

A new study shows that burning crops such as corn and switchgrass to create electricity to power electric vehicles would actually yield more transportation miles than turning those crops into ethanol.

Switchgrass ethanol, though, can yield 540 percent more energy than is required to produce it, the new study says.

Yes, we did recently report on a study which showed that switchgrass could potentially yield 5 times more energy than was used to grow it and, yes, there are several companies that are working hard to bring cellulosic ethanol to market.

A longer growing season and superior photosynthetic efficiency contribute to Miscanthus» high yield The two principal reasons why Miscanthus yields more ethanol per acre than corn, Long explains, are that it makes green leaves 6 weeks earlier in the growing season and keeps them until late October.

Switchgrass a better biofuel source than corn (1/7/2008) Switchgrass yields more than 540 percent more energy than the energy needed to produce and convert it to ethanol, making the grassy weed a far superior source for biofuels than corn ethanol, reports a study published in Proceedings of the National Academy of Sciences (PNAS).
