Electrolysis Breakthrough for Solar Storage
Inspired by the photosynthesis performed by plants, researchers at the Massachusetts Institute of Technology (MIT) have combined a liquid catalyst with photovoltaic cells to achieve a super efficient (nearly 100%) electrolysis.
This becomes a very effective storage system. One obvious extension of this would be the cost-effective storage of daytime solar energy for night-time use. Excess capacity during the day could be stored as hydrogen and oxygen, then used in fuel cells at night when needed.

Those playing with onboard electrolysis for hydroxy gas injection into the air intake might find this development to be noteworthy as well.

How it Works
Historically, the platinum electrodes used in electrolysis work well for splitting off the hydrogen, but platinum works very poorly for oxygen. The MIT catalyst works well to allow the efficient liberation of the oxygen.
The new catalyst developed by MIT researchers consists of cobalt metal, phosphate and an electrode. When the catalyst is placed in water and electricity runs through the electrode, oxygen gas is produced.
When another catalyst is used to produce hydrogen gas, the oxygen and hydrogen can be combined inside a fuel cell, creating carbon-free electricity to power a house or an electric car, day or night.
The patented catalyst formulation can be used in inexpensive, open containers. The new catalyst works at room temperature, in neutral pH water, and it's easy to set up, Nocera said.
patented catalyst formulation
Currently, MIT is working with photovoltaic cell manufacturers to incorporate electrolysis using their catalyst into solar energy systems.
The project is part of the MIT Energy Initiative, a program designed to help transform the global energy system to meet the needs of the future and to help build a bridge to that future by improving today's energy systems.
Funding was provided by the MIT Energy Initiative, the Chesonis Family Foundation, the Solar Revolution Project and the National Science Foundation, with a goal to make the large scale deployment of solar energy within 10 years.

MIT scientist develops artificial solar cell leaf that can power a house for a day with a single gallon of water - Daniel Nocera recently told attendees at the American Chemical Society that when his prototype leaf is placed in a pool of water, it effectively captures sunlight and splits water into oxygen and hydrogen at ten times the rate of a natural leaf. Operating for at least a full 45 straight hours without any decline in performance, the leaf acts as a small, highly-efficient solar cell that produces energy for use in power generation.

A Virus That Might Make Hydrogen - A team of scientists lead by material science professor Angela Belcher has genetically modified a virus that can exploit sunlight to split water into oxygen and hydrogen. If viable, the process could help solve the vexing problem of energy storage and the equally vexing problem of producing hydrogen in a reasonable and cost-effective way.

With Artificial Photosynthesis, A Bottle of Water Could Produce Enough Energy To Power A House - Like organic photosynthesis, Nocera's reaction uses sunlight to convert carbon dioxide and water into oxygen and energy. However, whereas plants create energy in the form of sugars, this process creates energy in the form of free hydrogen. ARPA-E gave Sun Catalytix $4 million nder the Recovery Act.

- MIT researchers split water to store solar energy - The idea is to use the energy from solar photovoltaic panels (or another electricity source) to crack water molecules into hydrogen and oxygen gas. Those gases would be stored and used later in a fuel cell to make electricity when the sun is not shining. The concept is a closed-loop system: running the hydrogen and water through the fuel cell creates water, which can be captured and used again. The hope is that within 10 years, a cost-effective system that combines clean energy generation with storage can be engineered and available cheaply to people around the world. (CNET; July 31, 2008)
