Hydrogen proponents likely know that Mirai means “future” in Japanese, but Toyota is only just beginning to explore how important the fuel cell stack in its H2-powered passenger car will be to the future of the company.

Toyota debuted the third iteration of its hydrogen-powered, Class 8 semi-truck on Earth Day at the Port of Los Angeles as part of the Zero and Near-Zero Emissions Freight Facilities Project (ZANZEFF) run by the California Air Resources Board (CARB). Using a Kenworth T680 Class 8 model as a starting point, this truck was developed in partnership with Kenworth and replaces the original diesel engines that displaced either 12.9 L or 10.8 L, with two solid polymer electrolyte fuel-cell stacks that are exactly like the one used in each Mirai.
