Hydrogen-powered electric vehicles are on the rise. Electrification of powertrains, along with limitations in battery technology, give rise to hydrogen-powered, fuel cell electric vehicles (FCEV). However, one of the challenges for FCEV is to efficiently and safely store hydrogen (H2) in the vehicle.
Hydrogen for FCEV is typically stored in type IV composite pressure vessels. The high operating pressure requires a significant amount of carbon fiber for the vessel. With up to 700 bar nominal pressure, one tank consumes up to 10 kg of carbon fiber for every 1 kg of hydrogen stored. With a typical tank size of 4-6 kg of hydrogen for passenger cars, a tank weights up to 40-60 kg. For larger tanks, the material economics only improve slightly.
We at Cevotec have developed a solution for this challenge. Read on to learn more!
