Abstract

The concept of harnessing energy from buoyancy as well as the ability to have underwater energy storage is an area of research that, compared to other renewable energy generation techniques, is relatively unexplored. This study presents an experimental analysis of a buoyancy generation and storage system. Tests were performed under standard laboratory conditions with the primary fluid being chlorinated municipal tap water. The buoyancy systems were designed, fabricated, and tested, with a focus on scalability and the need for results extrapolation. The system charge cycle was analyzed based on the system discharge voltage. Energy losses in the system due to drag or mechanical loss were estimated. The power generation and storage system utilized air transfer between containers to account for buoyancy increase and decrease in the main air vessel. Both systems were designed to function as standalone systems. Key variables of the experiment were the system float and the charge depth. Conclusions are based on experimental observation and compared with expected results from theoretical analysis, with a focus on performance improvement and real word practicality.
