> Can Hydrogen be used to store energy at the scale of a power grid ? The peak vs minimum variance in renewable sources is still an unsolved problem, and the only good solution (nuclear) has become politically untenable. To a large part is doesn't even need to. Even just the need for non-fossil chemical feedstock is so high that shaving the peaks of oversized generator fleet is enough to contribute to most of grid balancing. Just for ammonia synthesis at current global consumption levels you'll need hundreds of gigawatts of average power to generate the feedstock hydrogen.
