In this work, we are confronted with one of the main problems of renewable energy sources – their inflexibility. We want to have a resilient power grid that can avoid shutting down power sources when there is a surplus of power in the grid. This can be achieved by storing energy in various ways, such as air compression. Such storage would increase the effective runtime of renewable energy sources and thus contribute to a higher share of green power in the grid. In the research part of the paper, we searched for currently active energy storage systems and compared them with compressed air storage systems. We then used the Automation Studio simulation tool to simulate our system based on the pressurized grid at the Faculty of Mechanical Engineering. We also developed a working generator that, in combination with a pressurized system, can store energy through air compression and later return it as electricity. We found that the efficiency of our system is extremely low. In the conclusion, we have therefore also made suggestions for improvements and further research.
