Hydrogen tech has been around for decades, and it seems to always have had these same issues at varying degrees. To me it seems like a technology that in theory sounds great, but the moment you start trying to implement anything practical at scale, it all breaks down and becomes cost prohibitive. Solar initially had similar issues, but we’ve made significant progress there, when it seems like hydrogen has stagnated over the same time period. We should continue to research it, but I think our energy could be better spent by developing non-volatile battery technologies and making solar even more efficient and compact. I’d love to be wrong though.
