A not so utopian vision of hydrogen economy

Pipe dreams. ‘The year is 2050 and traffic no longer makes a noise. The air is clean and fresh because what is coming from the vehicles’ exhaust pipes is not black, sooty, choking gases but a stream of warm water vapour. This is because cars no longer run on petrol or diesel. Instead, when you pull into the filling station and insert the nozzle into your fuel tank, what comes out of the pump is hydrogen.’
