Hydrogen is often touted as a clean fuel source, as its use in cars only produces water vapor as a byproduct. The truth is though, that producing hydrogen in the first place can often be a process that relies on natural gas or other polluting chemicals that can damage the environment. Finding a way to produce hydrogen simply and cleanly would go a long way toward eventual use of the gas as a fuel source. And that's exactly what researchers at the University of Cambridge have done, adding to a host of other green possibilities that have been proposed for creating the gas.
