Nanotechnology to Make Hydrogen Fuel

What's the Latest Development?
A California company has announced its plan to build the world's first prototype for a 'nanotechnology-based, zero-carbon' process for producing renewable hydrogen and natural gas. Using waste water, HyperSolar, Inc. will use an artificial photosynthesis process to break down water molecules into their constituent hydrogen and oxygen elements. A similar project at the University of California, San Diego, uses a 3D nanowire to split water molecules using a photoelectrochemical process, requiring the presence of sunlight to function.
