SoCalGas White Paper on Cleaning Up Heavy Duty Vehicles
Advocates Technologies Successfully Used in Light Duty Sector

Ultra-low-emission heavy-duty natural gas engines can help California achieve its air quality, climate protection and petroleum-displacement goals – if policymakers and manufacturers emulate the success of smaller vehicles, states a new report from Southern California Gas.

Pathways to Near-Zero-Emission Natural Gas Heavy Duty Vehicles was drafted for the utility by Fleets & Fuels publisher Gladstein, Neandross & Associates.

“We must accelerate the commercialization and deployment of ultra-low emission heavy-duty vehicles – in addition to all that is being achieved with light-duty vehicles – to clean up California’s air, particularly in the hard hit South Coast Air Basin and San Joaquin Valley,” says GNA president Cliff Gladstein, one of the authors of the report.

‘Regulators Can Expand the Menu of Options’

The GNA-authored paper identifies near-zero-emission, natural gas-fueled heavy-duty vehicles as a key strategy that can significantly enhance California’s efforts to achieve its challenging air quality and climate goals.

“Regulators can expand the menu of options available to the market,” Gladstein said. “Heavy-duty natural gas engines are on a trajectory to achieve ultra-low-emission levels that will provide air quality planners with a crucial tool in their efforts to restore clean air to California sooner.”

Technologies now in development promise to reduce emissions from heavy-duty natural gas engines to the equivalent of electric vehicles getting their power from modern combined-cycle natural gas power plants. They include

  • advanced after treatment and waste heat recovery,
  • lean-burn plus lean-NOx emissions traps,
  • integration of zero-emission miles technologies,
  • further refinements in reducing friction and parasitic energy losses, and
  • widespread utilization of renewable and natural gas and hydrogen blends.

Integration of these technologies will increase the likelihood that California can meet smog reduction requirements, and also help heavy-duty natural gas engines meet the 2050 goal to reduce GHG emissions by 80%, GNA says.

“By combining advanced, near zero emission natural gas technologies in the heavy-duty sector with innovations already being deployed in the light-duty sector (electric drive, plug-in hybrids, fuel cells, and near-zero emission natural gas vehicles),” Gladstein said, “a strategy becomes available to bring California more expeditiously towards achieving ambient air quality standards.”
