Toyota (NYSE:TM) announced in April of 2023 that it was recently granted a Zero Emission Powertrain (ZEP) Executive Order from the California Air Resources Board (CARB) for its new heavy-duty fuel cell electric powertrain. The hydrogen-fueled powertrain kit includes hydrogen fuel storage tanks, fuel cell stacks, batteries, electric motors, and transmission. “It offers a viable alternative to traditional diesel powertrains used in commercial goods transportation as companies look to transition fleets to zero-emission vehicles,” Toyota said.
