The energy content of hydrogen is described by its (lower and higher) heating value. The lower heating value of hydrogen can be expressed as 33.33 kWh/kg or 2.78 kWh/Nm³. The higher heating value is 39.41 kWh/kg or 3.28 kWh/Nm³. A practical medium value to keep in mind is roughly 3 kWh/Nm³. The energy content of 1 Nm³ hydrogen gas is equivalent to 0,34 L gasoline, 1 L liquid hydrogen is equivalent to 0,27 L gasoline and 1 kg hydrogen is equivalent to 2.75 kg gasoline (based on the lower heating value).
