0.01MJ/kg
Nothing on our list is smaller: a lithium battery is 90× higher. To match a 60 kWh car battery you would need about 21,600 kg of it.
What it means
How much energy per kilogram?
Figures are the higher heating value by mass. They ignore the weight of the tank, engine or fuel cell around them.
The math
How to convert kJ/kg to MJ/kg
To convert kilojoules per kilogram to megajoules per kilogram, multiply by 0.001.
Example: 10 kJ/kg × 0.001 = 0.01 MJ/kg.
In the other direction, 1 MJ/kg = 1,000 kJ/kg.
