NGVAmerica has released its Fuel a Greener Future report, outlining the significant benefits of RNG-fuelled fleets.
RNG-fuelled medium and heavy-duty vehicles are commercially available, proven, and affordable, the organisation said. Depending on the feedstock, they can be carbon-free or carbon-negative.
Commercial pickups and vans, refuse trucks, transit buses, and Class 8 short-haul freight trucks cost-effectively run on RNG or biogas produced from methane emitted through the decomposition of animal manure, food waste, forest management waste, wastewater sludge, and municipal waste.
“Unlike other renewables, RNG is easily stored, distributed, and replenished,” said NGVAmerica president Dan Gage. “It is transmitted through existing refuelling infrastructure and when utilised as a motor fuel, RNG holds the lowest carbon intensity of any on-road vehicle fuel, including fully renewable electric from solar or wind.”
According to Q3 2020 data from the California Air Resources Board, the energy weighted carbon intensity value of California’s RNG vehicle fuel portfolio in the Low Carbon Fuel Standard (LCFS) programme is below zero – at 17.95 gCO2e/MJ – marking the first time in the history of the LCFS programme that any low carbon fuel portfolio has achieved a carbon negative status.
The report outlines the importance of utilising all available low carbon heavy-duty transport options available today to ‘dramatically lower’ overall transport-related greenhouse gas emissions and shares important information about the availability, resiliency, and sustainability of domestically sourced RNG vehicle and fuelling technology.
Natural gas vehicles are a ‘one-to-one’ replacement for diesel in terms of performance, torque, range, and capability, with immediate clean air and carbon reduction results, according to NGVAmerica.
“Climate change is cumulative,” added Gage, “the longer we wait, the harder it gets to solve. Investing in commercially available natural gas vehicles fuelled by RNG is the most cost-effective and immediate climate positive change policymakers can affect in 2021.”
