Title:
HYDROGEN ENERGY STORAGE SYSTEM, AND METHOD FOR CONTROLLING HYDROGEN ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/051417
Kind Code:
A1
Abstract:
A hydrogen energy storage system according to one embodiment of the present invention is provided with: a hydrogen generation unit that generates hydrogen through electrolysis of water by using power supplied from a power generation unit using renewable energy, and stores the generated hydrogen in a hydrogen storage unit; a hydrogen power generation unit that supplies the power generated by using the hydrogen stored in the hydrogen storage unit to a load; a power storage unit that charges/discharges power by an amount equal to the excess/shortage of the power supplied from the power generation unit to the load and that is quicker in control response than the hydrogen generation unit and the hydrogen power generation unit; and a control unit that executes control for reducing the energy stored in the power storage unit while charging/discharging power by an amount equal to the excess/shortage of the power to the power storage unit during a first period in which control is executed for causing the hydrogen generation unit to generate hydrogen.
