RE:RE:Some Practical Aspects of H2Not possible to swap out natural gas One kg of h2 has energy of 193,000 btus. So it takes 5 kg of h2 to equal one mcf of gas. Electrolysis processes may become a bit more efficient but physics is physics. Steam reformation means heating in a vessel over a catalyst bed to 800 degrees. I'll look into it. Bottomline Evs are cheaper than h2 with fuel cells.
