Propane, sure, but now you're talking about something fairly exotic, at least in terms of vehicles you can buy "off the shelf."
In any case, you can't produce propane yourself. You can "produce" electrons with a solar panel.
Edit: My bias is toward North America, but I know of only one model of "normal person car" (city buses don't count) produced in the last 50 years that you could just walk into a dealership and purchase new: The Honda Civic NX. And that was sold for only a few years and only available in California.

You can't store diesel forever, either.
