Hybrid grass may prove to be valuable fuel source

...eaton said. In contrast, the ratios exceed 0.8 for ethanol and biodiesel from canola, which are other plant-derived energy sources. Besides being a clean, efficient and renewable fuel source, Miscanthus also is remarkably easy to grow. Upon reaching maturity, Miscanthus has few needs as it outgrows weeds, r...

Green diesel: New process makes liquid transportation fuel from plants

..." About 67 percent of the energy required to make ethanol is consumed in fermenting and distilling corn. As a result, ethanol production creates 1.1 units of energy for every unit of energy consumed. In the UW-Madison process,...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort

...ry and a lead on the project. While many think of ethanol when they think of biofuels, the group recommends a much broader spectrum of possible materials including agriculture wastes such as corn stovers and wheat stalks, fast-growing trees such as poplar and willow and several perennial energy crops such a...

Corn waste potentially more than ethanol

...fessor of Environmental Engineering. "You can make ethanol from exploded corn stover, but once you have the sugars, you can make electricity directly." Logan's process uses a microbial fuel cell to convert organic material into electricity. Previous work has shown that these fuel cells can generate electr...
