??? Those are input powers of terrifically inefficient and expensive electrolyzers. That 250MW plant put out 17MW of hydrogen -- (120 (megajoules / kilogram))

??? Those are input powers of terrifically inefficient and expensive electrolyzers. That 250MW plant put out 17MW of hydrogen -- (120 (megajoules / kilogram)) * ((0.000236 kilograms) / (cubic foot)) * (2 200 000 ((cubic feet) / hour)) = 17,306,667 Watts.
- philipkglass 6y agoI think that you slipped a decimal point. The mass of a cubic foot of hydrogen is about 0.00236 kg, not 0.000236 [1]. That means that the output power is an order of magnitude greater than you calculated -- 173 megawatts.
