No. Hydrogen is a terrible, terrible fuel for transportation applications or to be transported for use for facility power generation because of its low density even when cryogenically densified into the liquid state (at 33 K under pressure or 20.3 K at ambient pressure), its flammability, high range of detonability, and embrittlement in many common alloys. If we were able to utilize hydrogen as a combustion fuel at a scale comparable to current use of petrofuels (especially at high altitude) it would have a substantial continuous impact on global heating because water vapor is a potent if not persistent greenhouse gas. And hydrogen reservoirs are neither large or concentrated, which would require a large amount of drilling for small return. Even if you buy the entirely unfounded speculation that there are vast accumulations of underground gas sufficient to satisfy “all our hydrogen needs for hundreds of years”, extracting, purifying, and transporting it would almost certainly come at a cost greater than just using renewable energy sources to electrolyze hydrogen for local use from available water sources.
It’s a dumb idea promoted by fabulists looking for a fanciful pixie dust solution that doesn’t require severe austerity, changes to the globalized system of commerce, or reduction of human population to sustainable levels.
