Yes, it's not uncomplicated. There's a guy somewhere in Sweden running his house in this way - he's got a bunch of hydrogen tubes in the basement that get filled up during summer. He's obviously an enthusiast and has paid a lot of money to build this, but at least it's somewhat practically possible. Edit: found an article about him (in Swedish, but the images are interesting and I think Translate would do a decent job): https://www.nyteknik.se/nyheter/fri-fran-elnatet-med-egen-vatgas-6344197 https://www.nyteknik.se/nyheter/fri-fran-elnatet-med-egen-va...
