Honda modified a Peterbilt to run on 3 hydrogen fuel cells, and it can go 400 miles with a full load.

Honda will showcase it, along with other fuel-cell vehicles, at the Advanced Clean Transportation Expo in Las Vegas on May 20. (A convention I haven't ever heard of until this moment)

Honda says the truck has an estimated top speed of 70 mph, and can travel 400 miles before refueling the fully loaded truck/trailer combo weighing 82,000 pounds.

Honda makes no mention of Peterbilt in its announcement, and images show Peterbilt badges removed from the concept.

“Honda is actively seeking business collaborations and customers to help bring these hydrogen fuel cell solutions to market here in North America.”
