Hydrogen FCEV How it Works

The hydrogen sold at True Zero stations today is transported in from facilities producing hydrogen for industrial uses. Two-thirds of True Zero hydrogen is derived from fossil fuels, such as natural gas. but one-third, in keeping with California state law, comes from renewable sources such as bio-mass.

How does hydrogen actually push a vehicle down the road? The hydrogen that comes from a True Zero dispenser flows to carbon-fiber fuel tanks where it is stored in the vehicle. The front grille on the vehicle allows outside air to flow into the fuel-cell stack under the hood. Hydrogen travels from the tanks to the fuel-cell where a chemical reaction creates the electricity that powers the vehicle.

Refueling with hydrogen takes just a few minutes. And as the acceleration of an HEV is terrific, the only real problem a driver should have is having too much fun behind the wheel.

Hydrogen FCEV

The Mirai Hydrogen FCEV

 The system is more energy efficient than internal combustion engines, and offers excellent environmental performance without emitting CO2 or other harmful substances during driving. At the same time, the system gives vehicles convenience on a par with conventional gasoline engine vehicles, thanks to a cruising range of roughly 650 km and a refueling time of about three minutes.
In addition, the Mirai can serve as a high capacity power supply during emergencies. It is capable of supplying roughly 60 kWh of electricity, with a maximum DC power output of 9 kW. When a separately-sold power supply unit is connected, the Mirai converts the DC power from the CHAdeMO power socket located inside the trunk to AC power and can power a vehicle-to-home*5 system or a vehicle-to-load system. Consumer electronics can also be connected directly and used from the interior accessory socket (AC 100 V, 1,500 W).

FCEV as a power generator

Vehicle-to-grid (V2G)


 Vehicle-to-grid (V2G) describes a system in which hydrogen fuel cell electric vehicles (FCEV), communicate with the power grid to sell demand response services by either returning electricity to the grid or by throttling their charging rate.  Hydrogen fuel cell vehicles (FCV) with tanks containing up to 5.6 kg of hydrogen can deliver more than 90 kWh of electricity.
