Solar Thermal Storage

Solar thermal storage enables the storage of heat collected from solar thermal systems for later use, improving reliability and dispatchability of solar energy. Thermal storage technologies include sensible heat storage, latent heat storage using phase change materials, and thermochemical storage. Molten salts are widely used in concentrated solar power plants due to their high heat capacity and thermal stability. Solar thermal storage allows electricity generation during cloudy periods or at night, addressing the intermittency of solar resources. It also supports load shifting and grid stability. Research focuses on improving storage materials, reducing thermal losses, and lowering system costs. Solar thermal storage plays a crucial role in large-scale solar thermal power plants and industrial heat applications, enabling continuous, low-carbon energy supply and supporting the transition to sustainable energy systems.
