The global green hydrogen industry has been wading through a series of setbacks in recent months. Nevertheless, deals continue to be made and R&D continues apace, with the aim of knocking natural gas off the hydrogen supply chain. In the latest news on the research end, the US startup SunHydrogen has just reached another milestone for its nanoparticle-enabled solar modules, which can produce green hydrogen in one step without the need for expensive electrolysis systems.

This sounds great! And years ago I thought we’d be driving hydrogen fuel cell vehicles by now. And somewhere along that timeline I came across the issues that hydrogen power density was so low, compared to burning hydrocarbons (oil, petroleum, etc) that it was hard to imagine it effectively replacing hydrocarbons. High pressure storage, as H2 gas was floated as a solution. Can someone ELI5 me why this is no longer the case, or that there is a path towards making H2 power density sufficiently high that it could theoretically work?
