Called the "Portal Project," the study will determine how well hydrogen fuel-cell heavy duty vehicles work in a shipping environment. The truck itself will be use two Mirai fuel cell stacks and a 12kWh battery to power two motors connected to the rear wheels working in parallel. With a range of over 200 miles per fill-up, the truck can haul a gross combined weight capacity 80,000 pounds.

"We think that there's a market demand for this technology in the ports today and there are no there are no competing services to diesel solutions," said Craig Scott, national manager of Toyota's advanced technology group.

Tony Gioiello, deputy executive director of port development for the Port of Los Angeles said "the Port of Los Angeles has been a leader in working to reduce pollution from port operations, and we're excited at the potential for a true zero-emission heavy-duty truck to push our Clean Air Action Plan even further."

The truck and the project are part of Toyota's larger plan to help kick start an infrastructure for hydrogen fuel cell vehicles like the Mirai. Initially the automaker will hire its own driver to help collect data on the big rig and it's trips. But it will eventually hand the keys over to the driver of a yet-to-be-determined shipping partner.
