The focus of this research is the production of hydrogen from water to organic compounds using light as the source of energy. Two systems are studied for producing hydrogen from water: the use of intact hydrogenase containing algae; and the use of spinach chloroplasts coupled to hydrogenase or synthetic catalysts. Since both systems produce oxygen by photolysis of water, a major objective is to develop methods for continuous removal of oxygen which will permit sustained production of hydrogen. The report describes photoproduction of hydrogen by intact algae; a coupled system of chloroplasts and hydrogenase; and the development of partial and completely synthetic systems for photoproduction of hydrogen. The report refers to recent publications describing this research and related studies in greater detail.
