On-tank valve for 700 bar hydrogen tanks

For hydrogen to really break through as an energy carrier for vehicles, a number of measures are needed. In addition to available refueling stations, it is especially necessary to improve the range. Currently, hydrogen tanks and systems in vehicles are 350 bar. If that pressure can be raised to 700 bar, that would be a huge step in the amount of H2 that can be carried. Besides the contruction of the tank itself, the on-tank valve is the most challenging component. In collaboration with Germany’s Poppe + Potthoff and China’s Tongji University, we developed a 700 bar on-tank valve. Read more
