NGVAmerica has pledged that by 2030, 80% of natural gas vehicle (NGV) on-road motor fuel in the US will be derived from renewable sources, rising to 100% by 2050.
In 2020, RNG collected at local landfills, wastewater treatment facilities, commercial food waste plants, and agricultural digesters displaced conventional fossil-derived natural gas sources as the dominant on-road NGV fuel source nationwide.
The carbon intensity (CI) of RNG continues to drop. California fleets that fuelled with bio-CNG in 2020 achieved carbon negativity for the year, with an annual average CI score of -5.845 gCO2e/MJ. The latest data puts the CI of bio-CNG in California’s system at -16.57 gCO2e/MJ (Q1 2021).
“NGVAmerica recognises that climate change is real and immediate investment is needed to clean and decarbonise all transport sectors,” said NGVAmerica president Dan Gage.
“The RNG motor fuel solution addresses two very real climate change concerns by capturing a waste liability, turning it into a green energy asset, and then using the resultant biofuel to displace diesel, cleaning up and decarbonising those sectors that are the dirtiest and hardest to abate.”
Investing in commercially available NGVs fuelled by RNG is the most cost-effective and immediate climate positive change policymakers can affect, said the association. The recently approved Senate Bipartisan Infrastructure Investment and Jobs Act of 2021 includes multiple opportunities to advance RNG motor fuel usage for clean school buses and ferries, transit buses, port operations and heavy-duty freight hauling.
According to NGVAmerica, there are currently 190 RNG production facilities in operation in North America with a further 232 facilities under construction or under substantial development (e.g. at the permitting stage).
