Silly comment.
Of course you wouldn’t use methane to produce hydrogen to be used to produce methane. One of the holy grails of catalytic chemistry has been efficient water splitting. That is the best place to find hydrogen for this process. And yes, it requires energy. My point was, simply, that if solar energy could create the current necessary to power this reaction, it would be an efficient way to produce a mobile fuel.
Of course, by trapping more solar energy, we could change the earth’s heat balance and create global warming.
(BTW, I am not a warmist, but I believe it is prudent to explore as many alternate energy processes as we can. It’s just good science.)

But electrolysis of water is far more expensive than steam reforming methane. That makes a bad idea even worse.
This scam is not about energy production, it is about carbon nature. They may have improved the losses but it still operates at a loss.
