Green-Y - Compressed Air Energy Storage System
The compressed air energy storage system from Green-Y leverages a patented technology that uniquely integrates energy storage with heating and cooling functionalities. This system operates by compressing air using renewable energy sources like solar power, storing it in high-pressure cylinders up to 300 bar. When the stored energy is needed, the compressed air expands to generate electricity, while the heat and cold produced during both compression and expansion phases are harnessed for various applications, from heating buildings to cooling server rooms. Its design focuses on sustainability, utilizing only air and water, making it a revolutionary alternative to conventional battery systems. The modularity of the system allows it to be customized for different project scales, offering flexibility in terms of both output and storage capacity. Additionally, it boasts a significant lifespan of around 20 years and yields energy cost reductions with an amortization period of just 3-7 years. This makes it an ideal solution for office buildings, industrial setups, and even residential areas looking to integrate renewable energy solutions and reduce reliance on fossil fuels.Compressed air energy storage for real estate and industry

The innovative and sustainable energy storage system from Green-Y is based on patented compressed air technology, which stores electricity and also generates heat and cold in a single system.
It uses air and water and has a service life of 20 years. The combined approach and the modular structure of the system promise amortization periods of 3 – 7 years.
When charging the storage system, air is compressed using electricity and stored in compressed air cylinders at up to 300 bar. Compression produces heat at a temperature of up to 60°C, which can be used for heating buildings, generating hot water or as industrial process heat.
When the storage tank is discharged, the air from the storage cylinders is expanded and generates electricity via a generator. During expansion, the temperature drops to up to 3°C. The resulting cold can be used for room cooling, server cooling or as industrial process cooling.
