Why not cut out the middle and go straight to steam power. After all we burn fossil fuels to make electricity that is then transported on copper wires to re-charge a car in 4 hours so that it can go 100 miles.

A nice methane powered flash boiler, a nice little triple expansion engine, bring her up to pressure in a few minutes and away you go. Main advantage would be that you would always have boiling water for a nice cuppa.
