How is hydrogen stored in Toyota Mirai?
Hydrogen in the Toyota Mirai is stored in carbon-fiber-reinforced fuel tanks. These tanks are designed to be safe, durable, and purpose-built for storing hydrogen. The hydrogen is pumped into these tanks, and after approximately five minutes, the vehicle is ready to be driven. The Mirai’s hydrogen fuel tanks have undergone rigorous testing and have been proven to meet Global Technical Regulation No. 13. In the event of a leak or collision, the hydrogen tank valves will automatically close to prevent further hydrogen from escaping, and any leaked hydrogen will safely return to the atmosphere.

What is the lifespan of a hydrogen car?
about 150,000–200,000 miles
The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.
How long does a tank of hydrogen last on a Toyota Mirai?
The Mirai refueling takes between 3 and 5 minutes, and Toyota expected a total range of 480 km (300 miles) on a full tank. The Mirai has a button labeled H 2O that opens a gate at the rear, dumping the water vapor that forms from the hydrogen-oxygen reaction in the fuel cell.
How does Toyota store hydrogen?
As you pump in the hydrogen, it travels to carbon-fiber-reinforced fuel tanks where it’s stored. After around five minutes, * you’ll be ready to hit the road.
Is there a downside to hydrogen cars?
More energy- and labor-intensive to store and transport hydrogen than gasoline or diesel fuel. Fuel cells are expensive to replace. Safety concerns over hydrogen flammability and electrical shock. Maintenance costs remain unclear.
Is hydrogen fuel difficult to store?
High density hydrogen storage is a challenge for stationary and portable applications and remains a significant challenge for transportation applications. Presently available storage options typically require large-volume systems that store hydrogen in gaseous form.
Is hydrogen difficult to store in a car?
The storage tanks in cars must withstand high pressures and be able to store hydrogen without any leakage. Several car manufacturers today use compressed hydrogen tanks in their cars, which are capable of 350 and 700 bars, depending on the automotive type (light duty/heavy duty).
Is Toyota discontinuing the Mirai?
Verdict The future of hydrogen fuel cell vehicles is still in development, and the Mirai isn’t giving up.
How is hydrogen stored for later use?
Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
How is hydrogen stored in a hydrogen vehicle?
To prevent hydrogen and oxygen reacting out of control during operation of a fuel cell car, the hydrogen in the vehicle is stored in gaseous form in thick-walled tanks, which are particularly safe. Numerous crash tests have validated the safety of this design: the tanks were undamaged and no hydrogen leaked out.
How is hydrogen stored in the Mirai?
The carbon fibre-reinforced plastic tanks store the hydrogen at a pressure of 700 bar. The MIRAI is powered by a 114 kW/155 PS* electric motor. Its high-performance fuel cell is backed with a battery that also stores the braking energy. With a tank capacity of five kilos, the MIRAI achieves a range of 500 km.
