Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent load on the environment and further supply power to meet demand and store surplus power in the form of fuel. SOLUTION: The system is constituted of a power station 1, a water decomposing device 3 or a device which forms fuel from hydrogen produced in the water decomposing device 3, and an auxiliary power generating device 6 which uses hydrogen or fuel to generate power. When there is little demand for power, the water decomposing device 3 is operated using energy from the power station 1 and thus produced hydrogen or fuel is stored. When there is a great demand for power, together with the power station 1, the auxiliary power generating device 6 is operated using the hydrogen as fuel or the fuel to generate power. The system may be constituted of a water decomposing device, a fuel producing device, a generator and a carbon dioxide separator to maintain the material balance substantially in a closed system. Further, a sea water decomposing device applicable to the system may be installed to prevent by-products harmful to the environment from being produced.
