Renewable Natural Gas Gains Momentum as Trucking Fuel

Progressively tougher clean air mandates and the increasing corporate focus on environmental sustainability could signal a larger role for natural gas — especially renewable natural gas — as a trucking fuel, experts said.

Although much of the industry’s conversation about alternative fuels has turned to electric-powered trucks in recent years, advocates for renewable natural gas, or RNG, point out that the fuel is capable of reaching net negative emissions of greenhouse gases by removing more carbon from the air than it creates.

RNG projects, unlike fossil fuel natural gas production, capture methane from existing food waste, animal manure, wastewater sludge and garbage, then repurpose it as a clean, green energy source, according to the Coalition for Renewable Natural Gas.
