The policy landscape is changing for renewable natural gas, and market opportunities for the domestic, renewable, clean fuel and energy source are expanding as well. Under the leadership of one of BCSE’s partner organizations, the Coalition for Renewable Natural Gas, states are advancing policies that promote the use of renewable natural gas (RNG). These policies are needed to create market certainty, which is necessary to drive greater development, deployment and utilization of RNG.
Thirty-seven states and DC have Renewable Portfolio Standards (RPS) programs, which can be met in part by producing renewable electricity from RNG. Many states and regions are also adopting policies that facilitate the use of RNG for transportation fuel. The Low Carbon Fuel Standard (LCFS) is the California regulation that requires a 10% reduction in transportation fuel carbon intensity by 2020. Governors of CT, DE, ME, MD, MA, NH, NJ, NY, PN, RI, and VT signed a 2009 memorandum of understanding committing to develop a regional low carbon fuel standard. Many states are considering new policies to create new markets for RNG, such as California’s Senate Bill 1440, which would establish a biomethane procurement goal for gas corporations.
As the policy landscape continues to evolve, states and the federal government should continue to support policies that promote the use of renewable natural gas, and result in longer term market certainty for this renewable energy and ultra low-carbon fuel.
RNG has many applications that make it a valuable and flexible resource. It can be blended with or substitute for conventional natural gas in vehicles as well as in commercial, industrial and residential end-use applications. RNG can be used to power your home or business’ natural gas appliances. It can also be converted to Compressed Natural Gas (R-CNG) or Liquefied Natural Gas (R-LNG) to fuel natural gas vehicles; many cities have transitioned their diesel bus fleets to natural gas engines fueled by renewable natural gas.
The Renewable Fuel Standard (RFS) is a federal program administered by the US Environmental Protection Agency requiring transportation fuel sold in the United States to contain a minimum volume of renewable fuel. Renewable Natural Gas meets the highest standards of RFS2 for lifecycle GHG emissions reduction, and currently comprises greater than 95% of all the cellulosic biofuel under the RFS program.
Many are familiar with natural gas, and with renewable resources, but what exactly is renewable natural gas?
Renewable Natural Gas (RNG, Biomethane) is an ultra-low carbon alternative to traditional natural gas. When organic waste breaks down naturally, it emits methane gas, also called biogas, a mixture of carbon dioxide and hydrocarbons. Renewable natural gas is biogas that has been upgraded to transportation fuel grade specifications or natural gas pipeline quality standards such that it may blend with, or substitute for, geologic natural gas. Large amounts of biogas (the raw, freshly emitted and untreated gas) can be collected at local landfills, wastewater treatment plants, commercial food waste facilities and agricultural digesters (dairies, etc.).
