I don't think most people consider it an energy source, more so a battery or storage medium. And cheaper storage is an important part of the renewables story because local supply can be unpredictable. I saw this article earlier today along those lines: https://www.smh.com.au/environment/climate-change/alchemy-of-energy-breakthrough-offers-mass-hydrogen-storage-options-20200702-p558dj.html https://www.smh.com.au/environment/climate-change/alchemy-of... Supposedly this stores hydrogen metal hydrides cheaper than lithium batteries, whatever that means, but I'm not qualified to judge.
