There's been a lot written about the BMW-Toyota tie-up but I think this is the first time I've seen the i3 mentioned as one of the vehicles that will utilise a Toyota fuel cell. Not sure just how accurate this report is but worth a read.

FCX Clarity tank is 170 litres at 350bar to get 240 miles.

Based on that FCX Clarity tank size then to give the i3 a 120 mile range would equate to a 85 litre tank (ignoring weight savings of i3).

The manufacturer figures for the new Toyota Mirai are 435 miles out of 5kg hydrogen which equates to 87m/kg. That seems to be a very big increase in efficiency compared to the older Honda and is likely to be less in 'real world' use but using that data would reduce the 85 litres down to 59 litres. That's beginning to sound more viable to package in the i3 but that's a lot of assumptions!
