HyperSolar to produce bio hydrogen, renewable natural gas from solar power, wastewater

In California, HyperSolar has released their plan to produce renewable hydrogen and natural gas using water and solar power, leading to unveiling a prototype by early 2013.  Their planned milestones to do this include: a proof-of-concept microparticle for hydrogen production using conventional photovoltaic elements, analysis of the feedstock potential of multiple wastewater sources, a complete photoreactor prototype for sustained hydrogen production, and design of nanoparticles using low-cost semiconducting materials.

The company states that after the hydrogen nanoparticles are optimized, the process of reacting hydrogen with carbon dioxide to make a renewable natural gas is relatively straightforward.
