Toyota Tacoma H2 Overlander Concept can recharge EVs, filter water

Hybrids, plug-in hybrids (PHEVs), and electric vehicles (EVs) may be all the rage today, but for brands like Toyota, they believe that hydrogen power still has a place in electrified vehicles.

At the 2025 SEMA Show, Toyota revealed what could be its most capable fuel cell electric vehicle (FCEV) to date. This is the Toyota Tacoma H2 Overlander Concept, and the automaker claims it can venture deep into the great outdoors and leave no traces behind thanks to its electrified powertrain. By combining FCEV and EV technologies into one, Toyota says the Tacoma H2 Overland Concept only emits water from its tailpipe, resulting in cleaner emissions.

At the heart of this FCEV pickup truck is a fuel cell stack and three hydrogen tanks that are housed within its frame rails. They are derived from the second-generation Toyota Mirai, which saves on costs and allows Toyota to use proven technology. The result is 6 kg of capacity, which allows the fuel cell system to combine hydrogen and oxygen, creating a chemical reaction that creates electricity and water vapor.

The powertrain is then augmented by a 24.9 kWh lithium-ion battery pack that powers a front electric motor that makes 225 kW and a rear electric motor that puts out 188 kW. The result is a combined system output of 554 PS and instantaneous torque delivery. The electric motors also come with regenerative braking to keep the battery charged up while on the go.

Since it's built for the outdoors, the Tacoma H2 Overlander Concept benefits from a front limited-slip differential and a rear electronic locking differential. In addition, the electrified pickup gets an array of chassis and suspension upgrades like a TRD billet long-travel kit, high-performance Fox 2.5 Performance Elite Series shock absorbers, bigger front disc brakes, and custom 17-inch alloy wheels wrapped in 35-inch off-road tires.

Other key upgrades in the Tacoma H2 Overlander Concept include a TRD cooling system to ensure thermal stability for the hydrogen & electric systems and a 15 kW power takeoff capable of running several appliances or charging EVs via dual NEMA 14-50 outlets.

But what could be its most unique feature is the patent-pending TRD exhaust water recovery system. It can capture and filter one of the only byproducts of a hydrogen fuel cell stack, water. Whether for camping or outdoor use, the distilled water contains no minerals and can be used for washing or showering. While not recommended for drinking, the distilled water adds significant utility in remote settings where water can be a scarce resource.

“The Tacoma H2-Overlander Concept embodies Toyota’s multi-pathway approach to carbon neutrality—showing that there’s more than one road to a cleaner future. At SEMA, under our theme ‘Powered by Possibility,’ we’re demonstrating that hydrogen isn’t just viable, it’s a core consideration in Toyota’s vision for what’s next. This concept proves that clean energy and real-world capability can go hand in hand,” said Mike Tripp, group vice president, Toyota Marketing USA.
