Design of Underwater Energy Storage System

Project Overview

Energy storage is the capture of electricity produced at one time for use at a later time. With increasing fuel prices, energy storage becomes more popular and financially practical. Some technologies provide short-term energy storage, while others can endure for much longer. Common examples of energy storage are batteries, hydroelectric dams, thermal storage tanks, and flywheels. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped. Underwater compressed air storage (UCAS) provides a promising low-cost alternative to bulk energy storage. Anchoring structures in the seabed imposes a technical challenge and an increased cost for any UCAS system. Additionally, the material of the UCAS is an area needing more development. For this project, we tested different types of anchors and designed. Also, we built and tested a prototype of UCAS in a swimming pool. The results seems promising and can be a good base for further researching and testing

Project Objectives

The main important objectives of this project are:
  • Design different anchoring methods and test them
  • Test a variety of materials that can be used for the UCAS
  • Test a prototype UCAS.
