Modelica is used for the analysis of steam accumula-tors used as energy storage systems in power plants and process industry. The analysis includes varying pressure accumulators and steam accumulators with latent heat technology. Physical models for the phase change material (PCM) and for the vertical discreti-sation of stacked volume elements are implemented in Modelica. Modelica is used for the analysis of new PCM enhanced steam accumulators which are not state of the art. The results of this analysis help to design these novel storage systems.
