New catalyst said to make electrolyzers 200 times more efficient

Massachusetts Institute of Technology (MIT) announced the development of a new oxygen production catalyst that is 200 times more efficient than platinum. The nickel-borate-based catalyst has been licensed to Sun Catalytix, which is hoping to be producing safe, super-efficient electrolyzers within two years.

The development of the catalyst was part of an MIT study into systems for making homes and businesses energy self-sufficient. Such systems would include rooftop solar panels to produce electricity for heating, cooking, lighting, and to charge the batteries on the homeowners' electric cars. Surplus energy would go to the electrolyzer, enabling it to produce more energy from water. At night, when the solar panels were inactive, the electrolyzer’s separately-stored hydrogen and oxygen would be fed into a fuel cell. This would result not only in nighttime electricity, but would also produce clean drinking water as a by-product. According to MIT, such a system could produce clean electricity 24 hours a day, seven days a week, even when the sun wasn’t shining
