Cella Energy, an Oxford based company, has claimed that it can produce a petrol replacement available in the next three years.
This fuel is hydrogen, but its innovative application is that it is stored in 'beads' and would not need to be stored in an expensive and potentially dangerous way it is stored at present.
This would mean that petrol would be much cheaper than current costs, with little infrastructure investment to implement the fuel.
Maybe this will loosen our dependence on oil, and give much less power to OPEC nations?
