A Multi-Criteria decision making (MCDM) methodology for high temperature thermochemical storage material selection using graph theory and matrix approach

Industrial waste heat is currently underutilized due to the techno-economic challenges, inherent variability and intermittency of this source. To overcome existing barriers, reduce emission greenhouse gases protect global environmental conditions, energy recovery one most effective strategies. In design storage systems, material selection procedure plays an important role requires complex interrelationships between various factors parameters be elucidated toachieve best candidate for a given application. This paper presents Multi-Criteria Decision Making (MCDM) methodology based on Graph Theory Matrix approach high temperature thermochemical (TCS) selection. Furthermore, presented has been used select suitable recovering (over 500 °C) in Port Talbot Steelworks.
