The main issue with changing energy source is a change in engine. Biodiesel requires little change, so it should be an excellent stop-gap as the industry hopefully hammers down on efficient, ethical and environmental energy storage.
That could easily be hydrogen, or even biofuel itself – the ultimate goal is to reduce the carbon cost of storing the energy. While lithium-ion has zero continuous cost, its initial cost is rather high, and if the battery is less efficient or prone to breakage more often its continuous cost (of repair and replacement) may well be worse.

They just use the hydrogen to generate electricity to charge the batteries, which then drive the motors: https://afdc.energy.gov/files/vehicles/hydrogen-high-res.jpg https://afdc.energy.gov/files/vehicles/hydrogen-high-res.jpg
- VBprogrammer 7y agoHydrogen can also be used in internal combustion engines with most of the benefits of reduced emissions (NOx not withstanding) with minimal modification. If there was a source, distribution and storage infrastructure for hydrogen we could start using it tomorrow. Personally I don't see much hope in that direction. Hydrogen combines high pressures with corrosive nature (see hydrogen embrittlement) and high flammability. Unless someone comes up with a really good storage matrix for it.
