Sažetak
An integrated system consisting of the combined electrolyzer and fuel cell units with hydrogen storage has been depicted. The system provides continuous power supply from intermittent renewable power sources. An analysis of system’ s application and economics has shown that the electrolyzer would operate with a low capacity factor dictated by the capacity factor of the renewable power source, and the fuel cell would have a capacity factor of about 50%. Because of the low capacity factors and relatively low round trip efficiency (about 50%) the cost of electricity produced and delivered by the system is several times higher than the cost of the electricity from the renewable source. This is the price for convenience of having the power from the renewable source available constantly. This may be acceptable for some applications.
