Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
Hence, hydraulic compressed air energy storage technology has been proposed, which combines the advantages of pumped storage and compressed air energy storage technologies. This technology offers promising applications and thus has garnered considerable attention in the energy storage field.
With excellent storage duration, capacity, and power, compressed air energy storage systems enable the integration of renewable energy into future electrical grids. There has been a significant limit to the adoption rate of CAES due to its reliance on underground formations for storage.
Energy storage equipment are promising in the context of the green transformation of energy structures. They can be used to consume renewable energy on the power side, balance load and power generation on the grid side, and form a microgrid simultaneously with other energy sources.
