Sand lifting-thermal energy storage technology for desert and Gobi regions and its economic analysis

Due to the volatility, intermittency, and uncertainty of new energy, the consumption and storage of new energy have become key constraints in building a clean energy system and achieving the dual carbon goals. Considering that China has abundant solar and wind energy resources and is also a region close to deserts, this article combines gravity energy storage and thermal energy storage technologies, using quicksand as the energy storage medium, and proposes a new energy storage scheme suitable for desert and Gobi areas. At the same time, based on the cost calculation method of energy storage per kilowatt hour throughout the entire life cycle, the economic and feasibility of sand lifting-thermal energy storage are analyzed, in order to provide a new idea for solving the problem of large-scale consumption of new energy in the southern Xinjiang region.
