The Hydrogen calculators
At Stargate Hydrogen we think of every detail to help your industry to reduce carbon emissions by adopting green hydrogen. That is why we created the Hydrogen calculators. Here you can calculate the mass of hydrogen, convert between hydrogen mass and volume, or convert between hydrogen mass and the energy content.

Hydrogen Calculator – Storage capacity
Calculate the mass of hydrogen that can be stored in a given volume and at a given pressure
Pressure
Enter a value between 1 bar(a) and 2000 bar(a)
Temperature
Enter a value between -73°C and 727°C)
Volume
Choose the amount of litres available for hydrogen storage
Mass of hydrogen stored
