But as a libertarian who has plenty of solar in large part to decouple me from my energy costs being prey to whatever whims the federal govt, state govt, or their cronies have in mind (and the absolute worst ones are the ones doing it under the auspices of saving the planet), I'm very much interested in hydrogen storage. About 1/4th of my power consumption comes from the grid, with the rest coming from solar. If I have a means to store my excess power for long term, like I'm hoping to do with electrolysis, and if I can do it safely, like I'm hoping with future hydrogen storage options similar to the Lavo system sold in Australia, I'll go off the grid living comfortably in my two-story home using plenty of A/C to counter the hot southern summer.
You do realize of course that the Lavo fuel cell while amazing is far less efficient than an actual battery. Despite what the picture looks like, it is the size of a large refrigerator and loses over half of the energy input to heat. To top it off they are very expensive. Currently, a bank of lead acid deep cell batteries would be far more efficient, very recyclable, and over their expected useful life, far cheaper. Lots of people are using them for off the grid living right now. You do not need to wait.

LAVO appears a viable prospect for 2022.
There is Plasma Kinetics which may be soon to market also. It uses a moving metallic hydride ribbon upon spools for storage medium. Light exposure releases stored hydrogen on demand.
