  • The application of a MCDM methodology based on Graph Theory and Matrix approach leads to selection of Cao/Ca(OH)2 for high temperature thermochemical storage.
  • Target based, universal and user-friendly MATLAB program based on MCDM methodology allows the simple selection of candidate materials.
  • The MCDM tool is tested against a real-life situation, namely the capture of waste heat from Tata Steel UK Port Talbot steelworks.
  • Practicality of proposed MCDM method is validated with selection of a suitable heat storage material for low-medium temperature application.
  • Proposed method can be applied to other scenarios such as heat storage from high and low temperature coupled with solar thermal generators.
