To achieve China''s goal of carbon neutrality by 2030 and achieving a true carbon balance by 2060, it is imperative to implement large-scale energy storage (carbon sequestration) projects. In underground salt formations, the salt cavern constructed by the leaching method is large, stable, and airtight, an ideal space for large-scale energy storage.
There are distinct classifications in energy storage technologies such as: short-term or long-term storage and small-scale or large-scale energy storage, with both classifications intrinsically linked. Small-scale energy storage, has a power capacity of, usually, less than 10 MW, with short-term storage applications and it is best suited, for
Energy storage can play an important role in large scale photovoltaic power plants, providing the power and energy reserve required to comply with present and future grid code requirements. In addition, and considering the current cost tendency of energy storage systems, they could also provide services from the economic
