Biofuels: Biomethane

Biomethane is a renewable natural gas produced from decaying organic matter such as waste water treatment sludge, food waste, animal manures, landfill gas, dead trees, and municipal solid waste through a process called anaerobic digestion.

Combining biomethane and natural gas technology is an effective way of supporting the state’s clean air and climate change goals. Use of biomethane to fuel natural gas trucks with certain emissions-reducing technologies can reduce criteria pollutant and greenhouse gas emissions to levels near those of zero-emission battery electric vehicles and hydrogen fuel cell electric vehicles.

Through the Alternative and Renewable Fuels and Vehicle Technology Program (ARFVTP), the California Energy Commission is supporting the production of sustainable, low-carbon biomethane for transportation use within California. The program is also supporting development and demonstration of the technologies that use this fuel to power vehicles.
