Is there a future for hydrogen (Water) fuelled cars?

This is been in the media spotlight quite recently, it all seems jolly exciting, but is there a future for it?

I don’t there will, as oil companies are not going to like it, the last thing they want is cars run on water. The industry would simply collapse, Oil has great economical importance to countries, maybe the oil companies will buy the plan’s to stop it from developing further, who know’s?
