Using coriolis flowmeters at 1050 bar design pressure for hydrogen refueling

May 11, 2024

Obviously, when vehicles fill up with hydrogen, they must be charged according to the rules. Hydrogen flow measurement is just a lot more complicated than measuring conventional fuels because the hydrogen being refueled is a gas. While temperature and pressure can vary, you still want to settle per kilogram of hydrogen molecules. That can only be done with a mass flow meter. But getting it really right isn’t that easy.

On-tank valve for 700 bar hydrogen tanks

May 4, 2024

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

Liquid hydrogen for aviation

April 13, 2024

AeroDelft has one mission: to prove that emission-free aviation is possible by pioneering electric aircraft powered by liquid hydrogen. Dreaming of a future where emission-free flying is possible: that was the dream AeroDelft started with in 2017. They formulated a very concrete goal: to fly from Amsterdam to London with zero emissions. The energy carrier in that case could be hydrogen. But to have sufficient energy density, the hydrogen will have to be massively compressed as a liquid on board. And that presents quite a few challenges. Challenges that AeroDelft is addressing and Teesing is helping with ultra light assemblies in aluminum. Read more
