ONE INNOVATION AFTER ANOTHER:

A Better Way to Get Hydrogen from Water (KEVIN BULLIS, June 19, 2012, Technology Review)

An experimental approach to splitting water might lead to a relatively cheap and clean method for large-scale hydrogen production that doesn't require fossil fuels. The process splits water into hydrogen and oxygen using heat and catalysts made from inexpensive materials.

Heat-driven water splitting is an alternative to electrolysis, which is expensive and requires large amounts of electricity. The new approach, developed by Caltech chemical-engineering professor Mark Davis, avoids the key problems with previous heat-driven methods of water splitting. It works at relatively low temperatures and doesn't produce any toxic or corrosive intermediate products.
