Corrosion Test of Salt Hydrates and Vessel Metals for Thermochemical Energy Storage

Among all thermochemical materials for thermal energy storage salt hydrates seem to be the most promising ones. Salt hydrates present the highest energy densities, but their main drawback is their bad compatibility with some container materials, such as metals. To control the corrosion effect it is necessary to perform and evaluate experimental tests. The main goal of this paper is to show experimental results of corrosion test between the most used salt hydrates for thermochemical energy storage and the most common vessel metals.
