• Current energy storage solutions have limitations in efficiency and lifespan, leading to energy waste and environmental impact.
• There is a need for an energy storage system like CARES that offers high efficiency, longer lifespan, and reduced environmental impact compared to existing solutions.

The technology behind this invention, Compressed Air Recuperated Energy Storage (CARES), can be summarized in five key points:

High-Efficiency Compressor:

• Utilizes a high-efficiency positive displacement compressor to compress air isentropically.

Volumetric Control:

• Employs a volumetrically controlled expander to maintain constant isentropic efficiency, irrespective of pressure ratios.

Cooling System:

• Achieves air cooling before compression by utilizing the low-temperature exhaust from the expander.

Thermal Energy Circulation:

• Minimizes thermal cycling losses by circulating thermal energy from a cold expander outlet to a hot compressor inlet.

Versatile Applications:

• Suitable for diverse applications, including renewable energy integration, grid stabilization, and industrial energy storage, offering improved efficiency and lifespan compared to conventional methods.
