Improved Way for Creating Hydrogen Developed Wednesday, September 24, 2008 - Roni Barr Home >> News >> Green Technology
A team of researchers at the Massachusetts Institute of Technology (MIT) have recently developed a new catalyst material, based on cobalt phosphate rather than expensive metals like platinum, which can be used for hydrolysis in water. Electrolysis breaks water into hydrogen and oxygen and is currently used in many industrial processes where hydrogen is needed. The researchers are hoping that the discovery could lead to homes that capture solar energy to make hydrogen for power.

The major problem with hydrolysis is its lack of efficiency due to the fact that power is needed to produce the electrical current that breaks the hydrogen and oxygen out of the water. In addition, the electrodes used in the process tend to be made from very expensive and precious metals like platinum.
The goal is for the new catalyst material to work in a closed-loop system that can make hydrogen with power gathered from solar energy or other electrical sources. The closed-loop concept would have hydrogen and water running though a fuel cell and the water would be recaptured and reused.

new catalyst, homeowners could use
their solar panels during the day to power
their home, while also using the energy
to split water into hydrogen and oxygen
for storage. At night, the
stored hydrogen and oxygen could
be recombined using a fuel cel l to generate
power while thesolar panels

Within ten years the researchers hope that the technology will be able to yield a cost-effective system that combines clean energy generation with storage. The new catalyst material can operate in plain water at normal atmospheric pressure.
John Turner from the National Renewable Energy Laboratories (NREL) says "The initial results look promising but it doesn't answer all the things you need in a catalyst." – More research is still needed to bring hydrogen to the consumer market as a cost effective way of producing power.

Letter to the Editor
Dear Sir,
With the past federal election, leaders from all political parties are revealing their environmental platforms and promising more green energy. I would like to know how they plan to help Canadian innovators and inventors who have been trying for years to get their energy saving technologies to market.
I am a private inventor who has developed a technology that was confirmed by the National Research Council (NCR) to be 2.35 times more efficient in producing and storing hydrogen energy than any technology known to exist. If this technology were to be fully developed and commercialized, it could make Canada entirely energy self-sufficient within a decade, as well as be exported to other countries. Without funding, however, I am unable to bring this technology to market and myriad benefits to Canadians, including employment and investment opportunities, are lost. My frustration is shared by many other Canadian energy innovators and technology deve
