Design, techno-economic analysis, and comparative assessment of high-temperature molten salt electric thermal energy storage systems for industrial heat decarbonization in Alberta, Canada
University of Alberta · National University of Sciences and Technology
Abstract
Alberta’s industrial sector requires substantial high-temperature process heat, yet its extreme ambient temperatures, which can reach −40 ∘ C, present challenges for thermal energy storage deployment. This study evaluates the techno-economic feasibility of electric thermal energy storage systems using binary chloride salts (50 wt% NaCl: 50 wt% KCl) contained in engineered concrete for delivering industrial heat at approximately 700 ∘ C. A single-tank configuration with an embedded air to salt heat exchanger is operated under different thermal charging configurations, including electric heating powered by solar photovoltaic farms, wind farms, or the grid, and beam-down volumetrically absorbing concentrated…
