Leeds University scientists have broken the ice and discovered an energy efficient method of extracting both hydrogen and carbon dioxide from otherwise disposable vegetable oils.

The problem with these, although I don't agree with their developmental direction, is that they don't tolerate carbon very easily, and pure hydrogen is very hard to obtain from carbon-rich sources, such as methane or petrol.
