Hydrogen Potential from Coal, Natural Gas, Nuclear, and Hydro Power

Hydrogen can work as an energy carrier from multiple energy sources.  Here is the conversion factors for 1 kg of hydrogen from a National Renewable Energy Lab document.


Hydrogen from coal: 7.6 kg of coal/kg hydrogen

Hydrogen from natural gas: 4.5 normal cubic meters/kg of hydrogen

Hydrogen from nuclear and hydro power: 58.8 kWh/kg of hydrogen

On average, about 3 gallons of water are needed to produce 1 kg of hydrogen

1 kg of hydrogen can potentially displace 4.35 kg or 1.58 gallons of gasoline

The document also has maps showing possible sources of Hydrogen.  Below is Nuclear and Hydro.
