MIT chemist Daniel Nocera claims that with just one bottle of drinking water and four hours of sunlight, he can generate 30 KWh of electricity, being enough to power an entire home. This process consists in a a cobalt-based catalyst that uses solar energy to split water and produce hydrogen.
Using the electric energy obtained from a 30-square-meter photovoltaic array, Nocera’s catalyst converts carbon dioxide and water into oxygen and hydrogen. The process is just like photosynthesis, where plants generate energy in the form of sugars instead of hydrogen.
This hydrogen produced through artificial photosynthesis can be converted directly into liquid fuel or recombined with oxygen in a fuel cell. Nocera’s start-up company, Sun Catalytix, will soon make the system affordable enough to allow individual houses to produce their own fuel and electric energy on-site. The problem of hydrogen transportation could be solved if the hydrogen production would be distributed this way.
“If I could store the sun in terms of a fuel, then at night when the sun goes down I can use the sun, effectively,” Nocera said in a company video. “What we’ve done is that we’ve made sunlight available 24 hours a day, seven days a week.”

Hydrogen Created by Artificial Photosynthesis ProcessA team of scientists from the University of Rochester has a tough mission creating a hydrogen fuel cell that not only burns cleanly but the fuel itself has to be created from clean sources. They have developed a process that uses artificial photosynthesis and nanotubes to finalize this project.
Daniel Nocera's Sun Catalytix Receives $7.1 Million for Developing Photosynthesis SystemDaniel G. Nocera of the Massachusetts Institute of Technology is the inventor of the most important solar energy system of the century. His 2007 designed system is able to create cheap solar energy based on the photosynthesis process.
Synthetic Leaves Performing Artificial PhotosynthesisA team of scientists at MIT and Michigan along with researchers at the University of California have discovered that artificial photosynthesis could produce electric energy.
Tennessee Scientists Generate Hydrogen With PhotosynthesisProf. Bruce isolated the core of the photosynthetic process from certain algae, and proved that, if coupled with a platinum catalyst, it could produce hydrogen in the presence of light. Photosynthesis is at the base of our fossil fuel energy, because it comes from the plants that lived here millions of years ago – indirectly, from the Sun.
Artificial Photosynthesis Succeeded Using Gold "Leaves"Kane Jennings and Peter Ciesielski, along with a team of scientists from the Vanderbilt University in Nashville, Tennessee, have been working to create the world’s first artificial leaf, that can do what natural leaves do: capture the light. More, their leaves transform that light into electricity. So, the nature’s 3.5 billion years work is now to be synthesized in a lab experiment. Here’s how they do it.

This is a good step forward but the follow through will have to be a hydrogen-based energy generation system for every home. It’s not too much of a technical hurdle (it’s the same technology as found in hybrid cars) but getting every home to purchase it’s own hydrogen power plant might be too big of a pill to swallow.

There is so much innovation and talent in our world. I just cannot believe we are still fumbling around in some aspects of industry, health and technology.

I really wish this was presented more clearly. The first paragraph implies that Nocera invented a photosynthesis system, which isn’t true. He’s is presenting a new and more efficient electrolysis system.
The solar photovoltaics are someone else’s job, so this is just part of the answer, not the whole answer. You still need to buy and install those expensive solar panels. Then with this system you can use the electricity produced to create hydrogen as a fuel.
This opens the door to cheap hydrogen generation. A crucial aspect, but not all the other puzzle pieces are in place. Storage is still being worked on by others, and conversion of hydrogen by fuel cells is yet another aspect for others to improve, although that seems to have some promising improvements lately,
