Gas from cow manure provides renewable fuel for vehicle, new energy study shows

摘要

San Francisco, Calif. - Methane gas derived from dairy manure offers a substitute for natural gas that can power motor vehicles, according to a study released by a collaboration of energy, dairy and environmental groups. Known as biomethane. the gas is entirely renewable and environmentally friendly, and can be produced locally. "There are 8.5 million cows in the United States, each producing enough manure to potentially generate about 30 cubic feet of biomethane per day, which could replace significant amounts of natural gas at today's prices," said Allen Dusault, Biofuels project manager for Sustainable Conservation. "If used as vehicle fuel, biomethane could power a million cars."
