TL;DR: In this paper, the authors proposed a compressed air electric power energy storage system achieving hydraulic and pneumatic coupling, where a compressor unit compresses air into a constant-pressure air storage device, liquid in the constant voltage air storage devices is compressed into a variable-pressure storage device through a liquid pump, and accordingly electric energy is converted to air and liquid internal energy for storage.

TL;DR: In this article, an isothermal-isobaric compressed air energy storage system was proposed, where an air compressor is used for compressing air into an underwater flexible air storage device at low electricity loads, thus the electrical energy is converted into the internal energy of the air and stored; and the high-pressure air in the air storage devices are subjected to heat-absorption by a heat exchanger and are used for driving a generator to generate electricity through an expansion engine at high electricity loads.

TL;DR: In this paper, a water pumping and compressed air energy storage system for electric power storage is described. But the authors focus on the characteristics of low manufacturing cost, no limitation to energy storage period, suitability for different power sources, environment friendliness and the like and have a wide application prospect.

TL;DR: In this article, a multi-level centripetal turbine system, comprising a turbine swelling system, a reheating system, and a transmission system, is described, where the amount of the turbines is even number and determined by a swelling ratio.
