I mean, this doesn’t have to go into cars / be distributed widely… it could just used to time-shift solar energy to night time by burning it on-site. Which mean

  Which is already solved: salt caverns work well.

    I checked and: "Salt caverns are artificial cavities in underground salt formations, which are created by the controlled dissolution of rock salt by injection of water during the solution mining process." Yeah, I don't have one of those in the garage unfortunately. I do have space for one of these though https://newatlas.com/energy/lavo-home-hydrogen-battery-storage/ https://newatlas.com/energy/lavo-home-hydrogen-battery-stora...

      Hydrogen is not the storage solution for your garage. A normal battery is better suited. Hydrogen is for storing weeks worth of energy at grid scale.

  I doubt even 15% efficiency would be there; along with massive maintenance/size issues. Solar is cheap and easy when it comes to maintenance, effectively no moving parts. Internal combustion (or a gas turbine) is a whole new development... and there is the storage. The best bet are still batteries, albeit the current incarnation of LiXXX (e.g. LiFePO4) are still not there. Even storing energy in batteries poses multiple conversions of electricity that goes to 92-95% efficiency.
