LPG. This started in Birmingham and has recently begun in London:

This is a Birmingham company that does conversions:

Obviously, the cost ...
The repowering will cost £10400
... can seem prohibitive, too, but the fuel is apparently cheaper.
The main problem is that there are still very few 'filling stations' that do LPG.
I also haven't been following how far the London offshoot of the scheme has got, but it was widely expected to get a good take-up.
I think many cabbies will opt for this instead of buying a new electric taxi. Obviously, there are still very few charging stations for electric cars/cabs in London. However, I still think that the London taxi fleet will be electrified earlier than others.
(I'm not too optimistic that widespread electric car use won't lead to a further increase in driving, by the way.)

Those new electric cabs are like £50k. Do you have any numbers of fuel costs for cabbies?
