Edit: I guess if you wanted to go fully off-grid, this would be a useful option.
I don't think private homes will have their own hydrogen production and storage facilities, this is more for industrial scale facilities.
May be you right, but people already use compressed air storage's to store energy at private homes.
Sure, they are low pressure, for safety.
But LOW pressure really easy achievable with plumbing technologies.
And learn physics, your life will change for better.
With good knowledge you will know, that in typical auto service electricity is not used, they use pneumatic elevator, pneumatic drill machines, etc.
Usually, in office environments, pressurized air created by electric compressors, but large share of mobile services use compressors powered directly from combustion engine, and every modern semitruck include compressor and could provide pressurized air in limited amounts.
If you want to continue this talk, write at least 5 most used cases of household energy usage. Not your energy usage, but how other people use it.

But sure, you could use garbage sources, and feed mind with infogarbage, if you wish.
And unfortunately, you behave rude, so I will not continue talk in this style, until you will answer my questions.
In Germany still exists lot of recognizable buildings, where stored methane. Some of them converted to culture/arts centers, because their specific design, not suitable for living or work (large cylinders).
