SAN FRANCISCO, CA - Methane gas derived from dairy manure offers a substitute for natural gas that can power motor vehicles, according to a study released today 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."
Manure can also be used to produce renewable energy through the process of anaerobic digestion. Minnesota dairy farmer Dennis Haubenchild reports, "My methane digester is producing enough electricity to run my operation plus another 80 residential homes." If installed on all U.S. dairies, methane digesters could generate enough electricity to power approximately 600,000 homes and provide an additional income stream for dairy farmers. At the same time, the technology reduces greenhouse gas emissions, which contribute to global warming, and reduces odors and pathogens.
