Scientists in water to fuel breakthrough

A DISCOVERY by Edinburgh University scientists could make it cheaper to make clean hydrogen fuel from water.

Hydrogen fuel cells burn hydrogen to release heat, which is then converted into energy. Water is the end product which makes it a clean way to produce energy.

Researchers have uncovered important details about chemical catalysts that use light to break apart water molecules, splitting them into hydrogen - for use as fuel - and oxygen. These findings will help researchers design photocatalysts that can operate at a range of temperatures, making the production of hydrogen fuel from water both cheaper and easier to control.

Professor Paul Attfield, of the University's Centre for Science at Extreme Conditions, said: "By understanding more about how they are structured, we will get the best results possible in producing green energy."
