>>MIT: Cobalt catalyst reduces cost of hydrogen production

Science Magazine on July 31 published a report by MIT’s Daniel Nocera and Matthew Kanan that they’d achieved hydrolysis at room temperature and pressure, using a cobalt catalyst in place of platinum at the oxygen-producing electrode.

The research opens the door to high-efficiency storage of solar and wind power. If the energy to split hydrogen from water can be made dramatically lower, it becomes much more economical to store hydrogen when the sun is high or the wind is strong, and recover the energy through a fuel cell overnight or during calms.

The traditional method of electrical hydrolysis is a high-temperature process, wasting a great deal of energy as heat. If the new cobalt-catalyst process proves scalable, electrolysis on a distributed household scale may prove practical.

Is this process scaleable for commercial use, or just a lab experiment?

Comment by Warren Ogren

Has the following headline “MIT: Cobalt catalyst reduces cost of hydrogen production” been refuted, or has it been/can it be validated by outside and independent sources? “Inquiring minds want to know”. I believe the original source, PV Today, has the responsibility to correct the article and refute it, or substantiate or validate the claim.

T. Brown: Your query refers to an article we posted 14 months ago. We’d not have run the report if it hadn’t been based on a peer-reviewed journal article. Check with MIT for further work. They’re still regarded (in this part of the world) as a reputable institution. Also note that the SOLAR TODAY blog now lives at http://solartoday.org/blog
