A cogeneration plant belonging to RWE Power in Dortmund, Germany could be the potential site of a novel heat storage project which aims to maximise efficiency for combined cycle gas turbine CHP units. RWE Power says it is starting to develop a high-temperature thermal storage technology specifically for this application under a co-operation agreement with ThyssenKrupp Xervon Energy, Paul Wurth Group and Deutsches Zentrum für Luft und Raumfahrt. RWE adds that preliminary studies already conducted confirm the general technical and economic feasibility, however, they add that the practical development of a CCGT power plant with integrated thermal storage depends on the availability of a commercial-scale, cost-efficient, reliable and long-lived high-temperature thermal storage facility.
