Across the United States and Canada, interest is accelerating in the potential for renewable natural gas (RNG), otherwise known as biomethane, to decrease transportation fleet emissions. RNG generates further interest for its potentially lower price point than competing fuels, as well as minimal friction to incorporate into existing operations. Yet, concerns with RNG’s emissions and supply security remain.
According to industry leaders, the findings are clear. "Renewable natural gas can be used in nearly every application that gasoline and diesel vehicles can be. ... Operationally, there is no limit," noted Ashley White, director and head of corporate sustainability of Clean Energy Fuels, which sells RNG.
