cost at scale is somewhat in questions In other words, it is not economically viable for anything beyond niche applications. Hydrogen is not a fuel. It readily reacts and forms strong chemical bonds with *everything*. It can be manufactured but not without the overall process being energy negative --- a net consumer of energy. Not many applications can realistically absorb this cost.
