Abstract
Meeting peak power demands can impose limiting conditions on generation, transmission, and distribution equipment in the electric utility network--especially around urban areas. Utilization of a cost-effective energy storage system capable of being located near the load centers could improve load factors and maximize utilization of installed capital equipment. A hydrogen-cycle peak-shaving system (HCPS) can be sited in populated areas, imposing no environmental concerns, and providing considerable flexibility not only in meeting peak load demands, but also in helping to meet varying system load-growth patterns. Several possible configurations for an HCPS are described, together with a summary of the features and benefits. An alternate "dispersed" HCPS system is also described for use by a combined electric and gas utility. One of the key elements in an HCPS system is an efficient, cost-effective water electrolysis unit. The General Electric Company has been working with the Niagara Mohawk Power Company, and others, since 1976 on the development of a unique solid-polymer electrolyte (SPE) electrolysis system which offers considerably higher efficiencies and potentially lower capital cost as compared with conventional commercial alkaline electrolyzers. The current status of this development program is discussed.Keywords
