New Hydrogen Producing Process Mimicking Natural Enzymes’ Work

Janina Lazo-Cruz — Thu, 06 Dec 2012 19:27:28 +0000

In pursuit of a cheaper alternative to the rare platinum as catalyst to producing hydrogen in a fuel cell, researchers from University of California (UC) Davis are utilizing a Japanese synchrotron in trying to unravel the catalytic mechanism behind enzymes called ‘hydrogenases’ that can also yield hydrogen, and be able to mimic these enzymes. Hydrogenases […]

A group of researchers from France revealed some tests in this week's issue of the journal Science that shows how platinum can be substituted with nickel, by mimicking the process going on in anaerobic-living algae. These have an enzyme, called hydrogenase, and use it to metabolize hydrogen.

Analyzing a single-celled green alga, researchers have found a fermentation process which was not known before that can revolution hydrogen production. Chlamydomonas reinhardtii, a soil or fresh water single-celled alga, produces its own energy by fermentation when it has no source of oxygen.

Genetic engineering allowed human kind to evolve and differentiate certain species of food, make them better or more productive. Likewise, genetic engineering is blamed to have ruined the natural evolution path of the affected plants or animals. Now, genetic engineering is being used to extract energy for us, in the form of hydrogen.

A company, named QuantumSphere, has designed a metal coating system made for electrolyzers, made out of nanoparticles of NiFe (Fero-Nickel, or in plain english, a combination between iron and nickel). This coating would cover the electrolyzers' anode and cathode and increase the actual contact surface with water by over 1000 times!
