Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Maize and other annual crops are easier to manage with traditional farming, but they are tougher on the environment. The researchers conducted ecosystem-scale comparisons of carbon, nitrogen, water, and energy fluxes of Sorghum bicolor with maize and Miscanthus x. Energy sorghum falls somewhere in between.

GM and US Army to demonstrate extreme off-road hydrogen fuel cell Chevrolet Colorado

Green Car Congress

Fuel cell propulsion has very high low-end torque capability useful in off-road environments. What’s more, fuel cells generate water as a by-product, something extremely valuable in austere environments. It also offers exportable electric power and quiet operation, attractive characteristics to both commercial and military use.

Enzymatic Process Converts Cellulosic Materials and Water into Hydrogen at Low Temperature; Close to Theoretical Yield of H2 From Glucose

Green Car Congress

Hydrogen production from cellodextrin and water by a synthetic enzymatic pathway. Researchers at Virginia Tech, Oak Ridge National Laboratory (ORNL), and the University of Georgia have produced hydrogen gas in a spontaneous, “one-pot” process using an enzyme cocktail, cellulosic materials from non-food sources, and water.
