To calculate the specific energy of hydrogen, we need to know the energy content of hydrogen and its mass.

1. The energy content of hydrogen is about 142 MJ/kg (megajoules per kilogram). This is the highest energy content of any common fuel by weight.

2. The mass of hydrogen is 1 kg (for this example).

So, the specific energy of hydrogen is calculated as follows:

Specific Energy = Energy Content / Mass
Specific Energy = 142 MJ / 1 kg
Specific Energy = 142 MJ/kg

So, the specific energy of hydrogen is 142 MJ/kg.
