WebSo, if you picture a gallon of liquid hydrogen, that same amount of hydrogen, existing as a gas, would, theoretically, occupy about 850 gallon containers (without compression). Hydrogen undergoes a rapid phase change from liquid to gas, so ventilation and pressure relief devices are built into hydrogen systems to ensure safety. WebThis means that if natural gas costs $6/million BTU, then hydrogen will be $18/million BTU. Also, producing hydrogen from electrolysis with electricity at 5 cents/kWh will cost …
