Small scale storage solutions would be helpful. It’s easy enough to produce hydrogen.

I think large scale storage such as geologic storage is key and can be connected to existing infrastructure via existing pipeline infrastructure.

Why would small scale storage be helpful in your opinion?

Hydrogen is not very energy dense and while it can be compressed well, there is some hesitation proliferating small scale compressed gas energy solutions on a national level. Until solid state (adsorbed) storage becomes a more viable option, I think I’ll continue to support large scale hydrogen projects over smaller ones (though I support energy diversification).

I’m thinking self sufficiency not corporate global resource control. Solar and hydrogen in the sunny north would be useful to homesteads with all the snow to electrolyze.

Ahh okay I see. I was imagining societal scale as I have no means to obtain this equipment myself.

Yeah you do. I have used a plastic bag to hold the hydrogen I made with my car battery, a glass jar, wire and salt water. That it. Not safe, that’s why I’m looking.

I am not interested in a demonstration, that is well within my means and I have had my fair share of fun igniting hydrogen. I mean I do not have the means to obtain a self sufficient energy grid which uses hydrogen for chemical energy storage. I would need solar or other production capabilities and a battery to make it worthwhile, and then all the hydrogen equipment. And by equipment I mean a somewhat efficient electrolyzer and gas handling systems with a compressor and storage tank. without that stuff, I think it’s more of a demonstration that fire can be made from water.

Yes, that looks like the sort of system I described.

Then I Guess hydrogen is good for making fire from water as you say. There are other systems that already exist and have been around since the 70s but this one looks ready finally.
