Answer: The pressure levels quoted are based on standard gas conditions, i.e. 15 ° C. We are also faced with the volume of hydrogen in Nm3, which is determined at a temperature of 15 ° C and a pressure of 101.325 kPa. From the user’s point of view, most often they talk about the injected kilograms of hydrogen. To convert Nm3 to kg of hydrogen, the formula 11.2 Nm3 = 1 kg is applied. The current market price for hydrogen at public hydrogen filling stations in Western Europe ranges from € 10 to € 15 per kg of hydrogen filled into a vehicle. Hydrogen prices are expected to fall in the future.
