I think if you are going to go with a highly energy inefficient storage medium then methane makes more sense. It's a lot more practical to transport and store.

I think if you are going to go with a highly energy inefficient storage medium then methane makes more sense. It's a lot more practical to transport and store. It can be carbon neutral as well if you use sabatier generators or bio reactors instead of fossil fuels. You can convert existing ICE engines to use it too. It's definitely not ideal, but it's still a fair bit better than the hydrogen options which generally just kind of suck. (3000PSI vs 5000PSI for CNG vs H2) If you can source something to dissolve it in you can also store it as LNG. Busses have been using it for ages now. Although I've seen what happens when an CNG tank goes on those busses and it is scary as heck. I can't imagine a similar issue with hydrogen. That stuff is scary. https://www.youtube.com/watch?v=vHf2o9oVY24 https://www.youtube.com/watch?v=vHf2o9oVY24
