SummaryMolecular hydrogen (H2) is an important energy carrier in environmentally-friendly applications, e.g. clean fuel cells, which are under development worldwide. However, presently the large scale production of hydrogen from water and sunlight is still a major challenge. In nature anaerobic bacteria use this molecule as energy source. The two major classes of hydrogenases, the enzymes that catalyze the production or the splitting of H2, were investigated by means of EPR and FTIR spectroscopy and quantumchemical calculations to elucidate the reaction mechanism.
