Sizing study of a hydrogen electrolyzer-gas turbine system

The aim of this paper is to determine a sizing methodology of a hybrid architecture composed of a power plant, an electrolyzer with hydrogen compressor; a high-pressurized gaseous storage, and a gas turbine. The purpose of such system is to replace a CO2-emitting electrical production provided by a natural gas fired turbine in Germany operating as a peaker by the hybrid architecture which also mitigates the intermittent power of a wind-only system. The proposed sizing methodology aims to determine range of power and capacity of each component, and associated operation profiles studied on an hourly basis.
