WebOct 2, 2024 · In electrical terms, the energy density of hydrogen is equal to 33.6 kWh of usable energy per kg, versus diesel which only holds about 12–14 kWh per kg. What this really means is that 1 kg of hydrogen, used in a fuel cell to power an electric motor, contains approximately the same energy as a gallon of diesel. WebThe lower heating value of hydrogen can be expressed as 33.33 kWh/kg or 3.00 kWh/Nm³. The higher heating value is 39.39 kWh/kg or 3.54 kWh/Nm³. The lower heating value of 3 kWh/Nm³ is usually used if the hydrogen is not burned directly. A practical medium value to keep in mind is roughly 3 kWh/Nm³.
