Abstract

With an increasing share of electricity from renewable energy sources in the German energy market, storage systems are needed to close the gap between production and demand. The thermochemical storage system based on the reversible reaction of CaO and Ca(OH)2 is one of the most promising approaches for high temperature thermal energy storage concepts. In this paper, a concept is developed to integrate a large-scale thermochemical storage system into an industrial heat and power plant. A mixed integer linear problem was created in TOP-Energy to conduct economical optimizations of the industrial heat and power plant with and without storage system. The linearization of the storage system was achieved by a correlation of input and output streams of a stationary CSTR MATLAB model. Hourly simulations for the years 2019, 2030 and 2040 with the help of energy price prognoses proved the economic benefit of the operation with storage system.
