A Dutch maker of valves, couplings and flow regulators claims it has developed what it calls a “sustainable 700-bar filling technique” for hydrogen cars.
The company, Teesing, says its PusH project successfully filled cylinders fast and efficiently with hydrogen at 700 bar.
The system runs at 700 bar because hydrogen has a lower energy content than natural gas, which means that the same volume contains three times less energy.
Refuelling hydrogen at a higher pressure, 700 bar, supplies enough energ
