California regulators have approved new rules that would see a massive shift from conventional gas and diesel trucks and vans to ones powered by batteries and zero-emission hydrogen fuel cells.
The first-of-their-kind guidelines, which take effect in 2024, cover a broad range of truck segments, from medium-duty models up to the “big rigs” that move vast amount of goods throughout California and across the country. Current guidelines from the California Air Resources Board already press manufacturers to add electric and hydrogen trucks to light-duty segments.
