1.78 trillion kWh of electricity are required to produce and liquefy 27 million tons of hydrogen per year

To produce and liquefy 27 million tons of hydrogen, a substantial amount of electricity is required. Throughout this wiki, we have used the kilowatt hours (kWh) to produce one kilogram of hydrogen as our baseline for determining how much electricity is required for hydrogen production. Therefore, we will first convert tons to kilograms. 1 ton equals 1,000 kilograms, 27 million tons is equivalent to 27 billion kilograms. It takes 66 kWh of electricity to produce and liquefy each kilogram of hydrogen. Multiplying 27 billion kilograms by 66 kWh per kilogram, we find that approximately 1,782 billion kWh, or 1.782 trillion kWh, of electricity is needed. This is a substantial amount of electricity equivalent to roughly 48% of the existing American power grid.
