Cheap And Easy Technique To Produce Hydrogen ...

From Visible Light Is Almost Ready

The prospect for the wide spread use of hydrogen as a portable energy carrier is dependent on finding a clean, renewable method of production. At Penn State University, a research group headed by professor of electrical engineering Craig Grimes in the Materials Research Institute is “only a couple of problems away” from developing an inexpensive and easily scalable technique for water photoelectrolysis - the splitting of water into hydrogen and oxygen using light energy – that could help power the proposed hydrogen economy.
