Electrohydrogenesis

Electrohydrogenesis

Electrohydrogenesis or biocatalyzed electrolysis is the name given to a process for generating hydrogen gas from organic matter being decomposed by bacteria [ [http://www.sense.nl/graduations/2648 Hydrogen production through biocatalyzed electrolysis] ] . This process uses a modified fuel cell to contain the organic matter and water. A small amount of electricity is used, the original article reports an overall energy efficiency of 288% can be achieved (this is computed relative to the amount of electricity used, waste heat lowers the overall efficiency). This work was reported by Cheng and Logan
