OK, you put in electricity and get hydrogen. So where are the efficiency numbers?
Just using an electrolyzer to break up water is about 70% efficient, in terms of energy out / energy in.
I realize there may not be an ideal oxygen mixture down there but wouldn’t there still be problems with using extreme heat in the presence of hydrogen???
I think there is literally no oxygen down there with the hydrogen. It’s the same with hydraulic fracturing of hydrocarbons. Plenty of methane COULD go boom, but there is no oxygen deep underground.
(Otherwise it would have slowly transformed into CO2 over the eons without our help)
