The lack of on-demand energy production capabilities, paired with the lack of sufficient battery technology, has been a major issue for renewable energy source viability. Compressed Air Energy Storage CAES offers the potential to mitigate the latter challenge with a safe, robust, and cost-effective method of storing excess renewable energy at the microgrid level. Positive displacement radial air motors serve as one potential method of extracting the energy back from the compressed air. This thesis aims to integrate such a motor with a corresponding control scheme into a small-scale CAES system to allow autonomous operation of the microgrid during times of little to no solar power availability. The motor would utilize the compressed air to maintain sufficient charge across the bank of a capacitor-based microgrid. Successful integration would help verify the capability of a small-scale CAES system in providing a resilient and environmentally friendly microgrid.
