Abstract
The Latent Heat Thermal Energy Storage (LHTES) systems can utilise eutectic salts to store heat and increase the capacity factor of the plant. These salts stored at high temperatures can adversely affect the compatibility of containment materials. Furthermore, an operational LHTES system is expected to be under varying degrees of stress due to the diurnal cyclic temperature variations, which can accelerate corrosion mechanisms. The combined impact of corrosion and stress is often neglected during the compatibility assessment of the material and its operating environment. This study proposes a novel static immersion corrosion testing approach using Compact Tension (CT) specimens that can investigate the interaction of alloys under stress in corrosive salts at high temperatures where the static structural Finite Element Model (FEA) can be utilised to estimate stresses. The application of this method can be extended to most systems that exhibit stress and corrosive environments. This conference paper focuses on exploring the theoretical basis, methodology, and experimental design of the research.
