Cellulosic ethanol can be derived from inedible crops like switchgrass, but the technology is still largely confined to the laboratory.

«One of the reasons for interest in these second - generation cellulosic feedstocks is that if they can be grown on low - quality soil, they wouldn't compete for land with food crops, such as corn.

The amount of biomass available from corn and food crops is very small; for biofuels to have a large impact, we must harness energy from nonedible plants, also known as cellulosic biomass — wood and wood waste, agricultural waste, and energy crops.

As it stands, such cellulosic biorefineries get their materials either from the residue of conventional crops, such as corn stover, or from harvesting trees.

Cellulosic ethanol will allow ethanol production from lands not suitable for crops.

In their quest to make cellulosic biofuel a viable energy option, many researchers are looking to marginal lands - those unsuitable for growing food - as potential real estate for bioenergy crops.

I saw your support for cellulosic ethanol, but no statement on the logic (or lack thereof) of the United States diverting some 40 percent of its corn crop to fuel while world grain prices soar.

Others have further elaborated on the carbon implications of various forms of bioenergy, from corn ethanol to crop residue cellulosic fuels to wood bioenergy.

Tennessee has the potential to produce billions of gallons of cellulosic ethanol by using 4.5 million acres of land identified by the Oak Ridge National Laboratory as ideal for energy crop cultivation.

If current levels of crop waste were used to produce biogas, 500 million gallons of cellulosic ethanol could be produced every year.

Because so little energy is required to cultivate crops such as switchgrass for cellulosic ethanol production, and because electricity can be co-produced using the residues of such cellulosic fuel production, reductions in greenhouse gas emissions for celluslosic ethanol when compared to gasoline are greater than 100 per cent.

Many of the corn ethanol plants can be easily modified to produce cellulosic ethanol from the waste of farm crops.

It is unlikely that crops grown specifically for the production of cellulosic biofuels will be developed in significant quantities as technology gains and bioethanol prices are unlikely to favour production over alternative crops.

The proposed changes included revising registration, recordkeeping and reporting provisions for compressed natural gas and liquefied natural gas; a lifecycle greenhouse gas emissions analysis for renewable electricity, renewable diesel and naphtha produced from landfill biogas; changes to deal with issues related to crop residue and corn kernel fiber when determining volumes of cellulosic feedstocks; a lifecycle analysis of advanced butanol; and changes to the E15 misfueling mitigation regulations.

Cellulosic ethanol proponents have pushed the idea of using farm waste as a way to boost biofuel production without impacting food crops, but such conversion may carry a hidden cost in areas with insufficient rainfall or lacking irrigation, warns a soil scientist from Washington State University.
