This project aims to test the feasibility of underwater compressed air energy storage (UWCAES) in the Red Sea offshore KAUST. This pilot project aims to measure pressure, temperature, and flow rate during charging and discharging of a small cylindrical PVC container deployed at water depths up to 100m. The data acquired provide insight into the system's performance and potential scalability. The equipment used in this field trial (e.g., storage tank, steel cage, sensors, and copper pipes) is custom designed and manufactured to fit the experiment. We expect all equipment to be ready for commissioning by early next year. Our experimental protocol will begin by testing the steel cage to determine its ability to withstand the buoyancy force encountered underwater. We also plan to do a series of tests on the storage tank combined with the steel cage to investigate the durability of the PVC material and its resistance to buckling. After that, we will conduct field trials at shallower water depths (e.g., 5m to 20 m) and later to 100m. Flow rate, pressure, and temperature measurements will provide insight into the system's functionality to compress and decompress air efficiently. The results from this pilot study will provide essential criteria to design and deploy a larger-scale experiment at water depths of 300 m, which we expect to meet the necessary pressure conditions to achieve successful energy storage.
