Poland’s P.H.U. Lechmar has partnered with France’s H2X-Defense to develop Hermione, a hydrogen-powered unmanned ground vehicle (UGV) that can refuel in only three minutes.
The wheeled platform stores hydrogen in high-pressure cylinders meeting European safety standards, supported by 25-kilowatt batteries for additional energy.
Its propulsion system uses electric hub motors rated at 8 kilowatts each, delivering torque and efficiently distributing power across all wheels.
