I just think renewable production of fuels is very cool because it can just be stored in a big vessel

Biodiesel or ethanol is what you're looking for. With our current methods, we spend so much energy making ethanol for E85 gasoline that it's nearly a 1-for-1 trade, but it doesn't have to be that way. We don't need to use huge gas-powered farming equipment; we didn't always use it in the past yet we've been farming corn productively for 5000 years.
