CARB Awards Grant for Ultra-Low NOx Truck Demonstration Project

California's ultra-low NOx emissions standard is 0.02 grams per brake horsepower-hour. This program will demonstrate the first diesel engine to comply with this state standard.

The California Air Resource Board (CARB) recently announced it is awarding a $7 million dollar grant to CALSTART for a Class 8 truck that will achieve a 90 percent reduction in NOx and a 15 to 20 percent fuel efficiency improvement.

The project is part of CARB's Low Carbon Transportation and Fuels Investments and Air Quality Improvement Program. CALSTART is the project grantee and administrator. The project will build and install Achates Power Opposed-Piston Engines into Class 8 demonstration trucks that will operate in fleet service in California in 2020.

CALSTART, based in Pasadena, Calif., is a member organization dedicated to the growth of a clean transportation technologies industry.

California's ultra-low NOx emissions standard is 0.02 grams per brake horsepower-hour (g/bhp/hr). This program will demonstrate the first diesel engine to comply with this state standard; the engine will emit 10 percent less CO2 than the 2027 federal greenhouse gas requirement.

The project team includes a heavy-duty truck manufacturer and leading suppliers in the powertrain and emissions industry. California's South Coast Air Quality Management District, the San Joaquin Valley Air Pollution Control District, and the Sacramento Metro Air Quality Management District are investing in the project.

Funding for the grant comes from California Climate Investments, a statewide program that puts billions of cap-and-trade dollars to work reducing greenhouse gas emissions, which improves public health and the environment.
