Energy - Switchgrass to hydrogen

Topic: Clean Energy

August 3, 2015 — Biorefineries could benefit from a new process developed at Oak Ridge National Laboratory that produces hydrogen from plant sources such as switchgrass. The method converts biomass waste streams into hydrogen through heating and processing in microbe-based electrochemical cells. This approach reduces the use of natural gas during biofuel production, which could help biorefineries lower their greenhouse gas emissions. “The production of renewable hydrogen from biomass is a long-sought technology for moving away from fossil fuels and toward a low-carbon economy,” said ORNL’s Abhijeet Borole. The team’s prototype set-up, which yields more than four liters of hydrogen per day, is detailed in Bioresource Technology.
