- as you have not filled in your location, I assumed you live in the U.S. Therefore I used Oregon average prices for fuel and kilowatt-hours :
here and
here. If you were so kind and let us know you live in the E.U., situation would be different.
- have you read provided sources? Have you read my post properly? You
need about 65 kWh to
produce 1 kg of compressed hydrogen by electrolysis, and that amount of hydrogen equals roughly to 3 liters of petrol in contained energy.
I did not start with kilograms, I cited this from abovementioned sources, but I can imagine why it is convenient to use mass instead of volume when talking about gases. Mass is a mass regardless pressure, and energy content is function of mass, not volume. Never mind, lets go on.
Even if you do not trust me, read please the second provided link. You can read that Norsk Hydro plans to sell 1 kg of compressed hydrogen for 90 NOK to be profitable. And they have a lot of cheap electricity. 1 kg of compressed hydrogens will move your car for 10 miles (same source, use google translate if you cannot read norwegian).
So - all physics set aside - this does not make sense for small scale manufacturer.
