Virginia Tech team develops process for high-yield production of hydrogen from xylose under mild conditions

Green Car Congress

A team of Virginia Tech researchers, led by Dr. Y.H. Percival Zhang, has developed a process to convert xylose—the second-most abundant sugar in plants—into hydrogen with approaching 100% of the theoretical yield. Support for the current research comes from the Department of Biological Systems Engineering at Virginia Tech.

Volvo Group’s New River Valley plant in Virginia achieves zero landfill status

Green Car Congress

Waste generated by the facility, which manufactures all Volvo trucks sold in North America, is now recycled, composted or converted to electricity. NRV began in 2003 by first identifying and evaluating all solid and liquid waste streams within the plant. Volvo’s New River Valley (NRV) assembly plant in Dublin, Va.

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.
