That the hon. Gentleman has gone green shows that the peace process really has worked. I can assure him that the Government are committed to ensuring that the UK meets its green energy commitments and that hydrogen plays an important role in that. I am in full agreement with the Prime Minister—well, I am always in full agreement with the Prime Minister, but particularly on this subject. I think the opportunity for hydrogen is extremely exciting and interesting, and it may be good enough to overturn this anti-car prejudice that some people have. If we have hydrogen cars, we can go back to enjoying all our motoring.
