Diesel generators will back up new electric bus capacity…

There are about 950,000 commercial trucks registered in California, and the vast majority are powered by diesel engines.
State law says that in 2023 and after, only trucks meeting or exceeding 2011 diesel emissions standards will be able to be registered in California, but today only about a quarter of registered trucks meet that criteria, said Allen Schaeffer, executive director of the Diesel Technology Forum. The trade group advocates for continued use of — and incentives for — diesel trucks using emission-reducing “clean diesel” exhaust treatments and cleaner fuels, including biodiesel.
Schaeffer believes California’s policies promoting electric and low-emission natural gas over clean diesel are counterproductive.
“Fleets are waiting to invest” because of uncertainty about which clean truck technologies will prevail, he said. “The result is that older trucks (that don’t meet the 2011 standards) are staying on the road longer.”
