PURPOSE: A renewable energy system is provided to electrolyze sulphuric acid solution and to use electric power generated from oxygen and hydrogen of the electrolysis as independent sources or distributed power by using electric power from an aerogenerator and a solar cell. CONSTITUTION: A renewable energy system contains a generator (10), an integrated regenerative fuel cell (20), a sulfuric acid storage (30) and a gas storage (40). The generator generates electric power by using a wind power generator or a solar cell. The integrated regenerative fuel cell generates hydrogen and oxygen from the sulphuric acid solution by using electric power supplied from a generator in electrolysis mode and generates electric energy using the hydrogen and oxygen in the fuel cell mode. The sulfuric acid storage supplies the sulphuric acid solution to the integrated regenerative fuel cell. In the gas storage, the electrolysis mode stores hydrogen and oxygen generated in the integrated regenerative fuel cell and the fuel electric cell mode supplies the stored hydrogen and oxygen to the integrated regenerative fuel cell.
