Everyone seems to be getting very hyped up about the supposed hydrogen revolution that is just around the corner. Fuel Cell powered cars, we are promised, will be 100% with only water as a waste product. We are told fuel cells are going to power everything from cars to laptops.
Does anyone else see problems with this proposal? Firstly, hydrogen is an incredibly volatile gas, so filling up cars etc. with it will be far more dangerous than filling them with petrol. Also, if a car full of hydrogen gas crashes and it ruptured the storage tank, the whole thing will explode at the first sign of a spark.
Second, hydrogen does not occur in vast quanities naturally, so we have to produce it. This requires energy, and surely this energy is just going to come from burning more fossil fuels in power stations. And if it doesnt, if we set up a renewable energy infrastructure, why do we even need hydrogen? everything (including vehicles etc.) could just be plugged into a mains outlet...
