And the overall efficiency is substantially worse than a conventional internal combustion engined hybrid. Significant amounts of fuel have to be consumed to generate the hydrogen. Fuel which could be used more directly and more efficiently. The only reason hydrogen fuel cells cars are feasible is that the electrical drive is so efficient. If they take that out they are completely missing the point. And anyway, at 420 Wh/kg new generation lithium ion batteries have a higher energy density than compressed hydrogen so I'm not convinced that fuel cells will take off. -- UCE probe.
