547 HP Toyota Tacoma H2-Overlander Concept Ditches Gasoline for Water

Built by Toyota Racing Development (TRD) engineers in California and North Carolina, the H2-Overlander is based on Toyota’s TNGA-F truck platform. It uses a fuel cell stack from the Toyota Mirai and three hydrogen tanks built into the frame, good for about six kilograms of storage. Those work together with a 24.9-kWh lithium-ion battery pack to power two electric motors—one up front and one in the rear—producing a combined 547 horsepower. Power is distributed through a front limited-slip and a rear locking differential for full four-wheel drive.

TRD didn’t stop at the powertrain. The truck features a long-travel suspension setup with Fox 2.5 Performance Elite Series shocks, upgraded Tundra brakes, and custom 17-inch wheels with 35-inch off-road tires. The team also designed a custom cooling system to manage temperatures for the hydrogen and battery systems during heavy use.

One of the more interesting ideas on the truck is its patent-pending exhaust water recovery system. Since hydrogen fuel cells only produce water as a byproduct, TRD figured out a way to capture and filter it for outdoor use. The water is clean enough for washing or showering, which could be useful when camping off-grid.

There’s also a 15-kilowatt power takeoff system that can run equipment or charge two electric vehicles at once using dual NEMA 14-50 outlets. In other words, it’s a rolling power station that can support a campsite or help a fellow off-roader who’s running low on charge.

The project came together quickly—TRD engineers had only a few months to turn a gas-powered Tacoma into a hydrogen-electric prototype. They used advanced CAD modeling, 3D-printed parts, and collaboration across teams to get it done. The concept also includes a roboformed TRD tailgate, an overlanding camper with recycled carbon-fiber panels, heavy-duty bumpers, a winch, and integrated recovery points.

Toyota says the H2-Overlander shows how hydrogen fuel cells could fit into the company’s broader approach to cleaner vehicles. It’s part of a larger SEMA display under Toyota’s “Powered by Possibility” theme, which has everything from traditional combustion engines to hybrids, plug-in hybrids, battery-electric vehicles, and fuel cell powertrains.

The Tacoma H2-Overlander Concept will be on display at the 2025 SEMA Show from November 4–7 at the Las Vegas Convention Center in Toyota’s booth (Central Hall, Booth 22200).
