Abstract
In order to strengthen the competitiveness of concentrated solar power plants, the development of costeffective storage options is indispensable. For power plants based on air receivers, the technology of direct-flow solid heat storage is an obvious choice. The heat storage inventory used is a significant cost factor for this technology. The use of slag from steel production could significantly improve the competitiveness of this technology. The ReSlag project deals with open questions on the suitability of electric arc furnace slag. This paper presents the final experimental investigations on a pilot scale for the use of sintered electric arc furnace slag in solid heat storage systems. The results of cyclic tests under different operating conditions as well as of standstill tests are presented and successfully compared with simulation results.
