US study shows switchgrass is a promising ethanol biomass

An on-farm study by the University of Nebraska – Lincoln has shown that switchgrass can produce 540% more energy than that needed to grow, harvest and process it into cellulosic ethanol.

Switchgrass

The five year study of switchgrass fields was conducted on farms in Nebraska, North Dakota and South Dakota. It is the largest switchgrass study to date and has examined the following from switchgrass that has been grown and managed specifically for biofuel biomass:

  • the net energy output;
  • greenhouse gas emissions;
  • biomass yields;
  • agricultural inputs: and
  • estimated cellulosic ethanol production

According to Dr Vogel, Adjunct Professor in Agronomy and Horticulture:

This clearly demonstrates that switchgrass is not only energy efficient, but can be used in a renewable biofuel economy to reduce reliance of fossil fuels, reduce greenhouse gas emissions and enhance rural economies.
