A novel underwater energy storage system is introduced and its round-trip efficiency is reported. A validated analytical model is used to predict the performance of a scaled-up system. Its performance is comparable to that of conventional pumped hydro systems. New elements such as a flexible reservoir do not contribute to energy losses.
Underwater compressed energy storage is similar to CAES, with the major difference being that the air is compressed in a container located underwater. Several approaches to UWCAES are under development including the utilization of distensible air container also referred to as an Energy Bag , .
In addition, a study developed by the team showed that an underwater energy storage system with 80 spheres could output up to 400 MW, and would cost between €0.04 to €0.20 per kWh (equivalent to $44-$220/MWh). A cost competitive option. 13
Underwater gravity energy storage has received small attention, with no commercial-scale BEST systems developed to date . The work thus far is mostly theoretical and with small lab-scale experiments . Alami et al. , , tested an array of conical-shaped buoys that were allowed to rotate.
You pump water to a reservoir located at a higher altitude when energy supply is higher than demand, and then release the water to drive turbines located downstream when demand is high. In underwater pumped storage, the power plant is already on the water, an enclosed vessel containing water is installed on the seafloor.
Compared with floating storage, underwater storage sustains less harsh environment loads from wave, wind, and current. UWCAES derives from onshore CAES and is one of the earliest developed offshore energy storage technologies. Compared with onshore CAES, the unique property of UWCAES is that the compressed air is stored and transmitted underwater.
