Abstract
The increasing demand for electricity, driven by population growth and technological progress, requires the development of sustainable energy systems. Integrating renewable energy sources, especially variable sources such as photovoltaics and wind power, introduces new challenges due to their intermittent and weather-dependent nature. To address the imbalance between energy generation and consumption, energy storage solutions are required. Micro-Compressed Air Energy Storage systems present a promising approach to stabilizing local energy grids by storing excess renewable energy and releasing it during peak demand. However, the widespread adoption of compressed air energy storage technology is challenging because of a limited understanding of air expansion dynamics, which lowers overall system efficiency. This study presents a theoretical model and experimental investigation of gas expansion processes in those systems. A series of test rigs was developed from constant-volume tanks to a fully integrated three-cylinder expander to capture the thermodynamic and mechanical behavior of compressed air. Experimental results reveal significant non-isothermal effects during expansion, emphasizing the importance of heat management. The validated model offers insights for improving energy recovery and system performance. The research infrastructure supports further exploration of storage installations, allowing a more efficient integration of RES with the energy system.
