Abstract

See full text

An objective of the present invention is to provide an energy conversion and storage equipment which is capable of efficiently generating hydrogen using varying electric power generated from renewable energy and is capable of storing the hydrogen. The invention is an apparatus for converting and storing renewable energy in which hydrogen is produced with a water electrolysis device using the varying electric power generated in renewable-energy equipment and the hydrogen is stored, the apparatus being characterized in that the water electrolysis device includes an oxygen generation electrode which comprises an Ir—Mn alloy oxide. Due to the application of the electrode, with which water can be electrolyzed using the varying electric power generated from renewable energy, the system suffers little electrode deterioration even when the varying electric power is used, and it is possible to highly efficiently produce and store hydrogen for a long period.
