I would like to see something like biodiesel electric hybrid. It can reuse infrastructure and could use solar to offset fuel consumption.

You mean like any of the Mercedes 300de/300de powertrains?

31kWh battery mated to a 2.0L diesel:

Like any diesel, this one could run on biodiesel with some adjustments.
