Why would it take away from shipping volume? A biodiesel or equivalent shouldn't take up any more room then current field?

Bio fuels are typically less energy dense than dinosaur squeezings. Diesel is around 40 mega joules per liter. Biodiesel is around 33.

So in this example you only get 82.5% of the energy unless you increase capacity of the fuel tanks, which would decrease the available space for cargo.
