What is actually the simplest answer why hydrogen is not feasible yet for a replacement of our usual ways to heat buildings or drive cars. I heard that Hydrogen makes sense for larger vehicles that have to drive for a lot of miles but smaller ones are not really in development outside of toyota’s experiments. Is there already a way to when it could get feasible?

Purely the cost. We can make hydrogen pretty easily and cheaply, but it uses natural gas to do it, so it is sort of pointless.
The holy grail is green hydrogen made using the electrolysis process. Splitting water molecules into hydrogen and oxygen. The technology is still being worked on, as it isn’t reliable and too expensive at the moment. Also it is energy intensive, so it won’t be viable unless you are producing tons of excess solar or wind energy. Then you could store all the excess as fuel. The cheaper solar gets, the cheaper hydrogen will get.
