The RFS provides a market-based monetary value for renewable fuels, including RNG.
Congress created the Renewable Fuels Standard (RFS) program in 2007 to expand the nation’s use of renewable fuels while reducing reliance on imported oil.
įederal and state programs for renewable fuels have provided incentives for projects to convert biogas into RNG. Use of RNG can provide benefits in terms of fuel security, economic revenues or savings, local air quality and greenhouse gas emission reductions. The number of farm-based AD projects generating RNG is increasing in California alone there are over 50 projects planned or under construction.Renewable Fuel Standard Program and the California Low-Carbon Fuel Standard (LCFS) and Oregon LCFS programs. Federal and state public policy initiatives have helped kickstart the RNG market by incentivizing renewable, carbon-negative energy.RNG is different than fossil-based natural gas because it comes from renewable sources. RNG can be produced from the degradation of manure and organic matter in an anaerobic digestion (AD) system.RNG is essentially indistinguishable from natural gas but is derived from biological materials rather than from fossil fuel deposits. It can then be injected and transported via natural gas pipelines and used as a substitute for natural gas. To upgrade biogas to RNG, the methane content is increased by removing water vapor, carbon dioxide, hydrogen sulfide and other impurities. RNG can be used for thermal applications, electricity generation, bio-plastic feedstock or vehicle fuel. The biogas used to produce RNG comes from a variety of sources including livestock farms, municipal solid waste landfills, water resource recovery facilities (wastewater treatment plants), waste products from food and beverage production, and organic waste management operations.
that has been upgraded for use in place of conventional natural gas. The principal constituents are methane and carbon dioxide. Renewable Natural Gas, often called RNG or biomethane, is a term used to describe biogas biogasGas resulting from the decomposition of organic matter under anaerobic conditions.
