Green Gasoline: A Renewable Petroleum Alternative From Plants
First-generation biofuels have been hampered by a range of factors, from incompatibility and lower energy yields to concerns about their potential impacts on food prices. A new, second-generation biofuel known as cellulosic gasoline, or "green gasoline," is positioned to bridge those gaps and eventually provide gasoline, diesel and jet fuel identical to petroleum counterparts. Derived from non-food plants and agricultural waste, green gasoline has the same performance and functionality as petroleum-derived fuels yet it fits into existing infrastructure.
On Sept. 23, 2008, three leading experts from academia and industry hosted a panel discussion at the National Science Foundation (NSF) to highlight how far researchers have come, and how far they still need to go, to bring plant-derived gasoline to market. Samples of energy-dense plants, such as switchgrass and poplar, from the U.S. National Arboretum's Power Plants--Farming Energy garden exhibit was also on display.
