Sentences with phrase «switchgrass yields»

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).

The National Commission on Energy Policy reported in December that, if fleet mileage in the U.S. rises to 40 mpg — somewhat below the current European Union fleet average for new vehicles of 42 mpg and well below the current Japanese average of 47 mpg - then as switchgrass yields improve modestly to around 10 tons / acre it would take only 30 million acres of land to produce sufficient cellulosic ethanol to fuel half the U.S. passenger fleet.

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.

After crunching the numbers, Vogel and his colleagues found that ethanol produced from switchgrass yields 540 % of the energy used to grow, harvest, and process it into ethanol.

Previous studies on switchgrass plots suggested that ethanol made from the plant would yield anywhere from 343 % to 700 % of the energy put into growing the crop and processing it into biofuel.

Switchgrass and hybrid poplars would produce relatively high ethanol yields on marginal lands, but it likely will be another decade before cellulosic ethanol can compete with corn - based ethanol.

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.
