Thermochemical energy storage systems, including chemical looping (such as calcium looping), salt, hydration, absorption and adsorption systems had the highest efficiency, up to 100 percent. However, the cost of this type of high-temperature thermal energy storage was higher than sensible and latent heat technologies, ranging between 80 and 160 euros per kilowatt-hour as of 2024.
