Abstract: An eco-friendly energy storage system for frequency regulation, includes: a water electrolysis apparatus and a hydrogen storage apparatus for performing discharge of surplus power for a power system; a fuel cell power generation apparatus for performing charge of deficiency power; and a control device for controlling charge and discharge by detecting a system frequency for controlling charge and discharge of the system, comparing the system frequency with a frequency reference value, and reflecting a frequency regulation amount calculated on the basis of a hydrogen storage amount of the system.
