Electrolysis is a method of producing hydrogen from water with the help of electric current. The electrolytic cell consists of two electrodes – usually inert metals such as platinum, a precious and expensive metal and which is responsible for the high production cost of electrolysers. “Using enzymes to replace platinum is a cost effective alternative to reduce costs and improve profits in the production of hydrogen form water”, assures Dr. Philippe Lorge – president of H2life foundation and director of development project of enzymatic electrolyser and fuel cell. Enzymes are catalytic proteins naturally present in vegetables and animals and can also be synthesized industrially.
For this project, Dr. Lorge got inspired by the natural process of photosynthesis – more precisely the first stage of photosynthesis. This consists of using solar energy and the photosynthetic enzymes to dissociate the elements (H and O) in the water. This method – termed enzymolysis or enzymatic electrolysis– is a renewable and a cyclical biological processes - the elements in the water are dissociated and then re-associated whilst the energy is produced.
