I'm running alternator-free right now with my LiFePO4. On my Insight the hybrid system has been removed, but I repurposed the electric motor as a 3 phase electricity source to power a Meanwell power supply which supplies a constant ~13.5v. Capacitors take care of transient load. I can't imagine there are much more efficient ways to generate and store electricity in a car.
