Molten salt thermal energy storage systems. Project 8981, final report

Corrosion of AISI316 as containment material for latent heat thermal energy storage systems based on carbonates

“…At industrial level, A316L and Inconel 625 are not recommended for service greater than a month when corrosion rates are higher than 1252 and 1184 µm/year, respectively [7]. Among all the LHS media, the most prevalent molten salts in use at industrial scale are nitrates and halides [8]. Carbonate mixtures have been chosen for this work as they present good performance at high temperatures.…”
