Hydrogen Cars 'Would Need Windfarm Size of Wales'
Converting Britain’s oil-burning road vehicles to hydrogen power would require the construction of 100 nuclear plants or a windfarm the size of Wales, according to an academic study.
Researchers at the University of Warwick estimated that 100,000 wind turbines would be needed to generate enough electricity to create “greener” hydrogen fuel to keep the nation’s cars on the roads.
Economist Professor Andrew Oswald and his brother, energy consultant Jim Oswald, laid out the startling calculations in an article entitled “The Arithmetic of Renewable Energy” to be published in Accountancy magazine.
Jim Oswald, whose consultancy is based in Coventry, said: “The enormity of the green challenge is not understood.
“Many people think that hydrogen is a simple alternative to oil, but in fact it will require a huge investment in either windfarms or nuclear plants.”
The researchers acknowledged that there are many good reasons to consider switching vehicles from oil to hydrogen, particularly concerns about oil consumption’s contribution to global warming.
But they also point out that many people are unaware that hydrogen is not a source of energy, but a carrier of energy, and has to be made, transported and stored using huge amounts of electricity.
