In an underwater pumped hydro storage system seawater is used as the working fluid instead of air. These devices use rigid spheres of steel or concrete that rest on the seafloor that pump surrounding seawater in and
PTES systems use grid electricity and heat pumps to alternate between heating and cooling materials in tanks, creating stored energy that can be used to generate power as needed.
A pilot-scale (c.a. 100 kW) PTES system using CO 2 as the working fluid was then designed, built and tested, including two HTR concepts and an ice/water slurry LTR. Data

Well-established large-scale storage systems are pumped hydro energy storage systems (PHES) having rated powers ranging from several ten MW to several GW. At present, almost 99% of the global storage capacity is realised by PHES. In 2030, IRENA expects a market share of 325 GW for PHES and 150 GW for battery technologies .
Test operation has confirmed that ventilation is not required. Storing energy offshore by means of hollow concrete spheres placed at the bottom of the sea is a very attractive solution to combine technical features of conventional pumped hydro storage systems with a huge resource potential around the globe in an economic way.
Compared with the established energy storage technologies, compressed air energy storage (CAES) and, in particular, pumped hydro storage (PHS), the PTES configurations of this study are characterised by a smaller installation footprint and no requirement for specific geographical constraints that significantly limit their use.
The piping of the pilot plant facility is divided into two different loops: the HTF loop and the molten salts loop (Fig. 2 b). The HTF loop consists of a stainless steel 316 L piping of 1″ of diameter. With the implementation of different by-passes, different flow arrangements (parallel and counter flow) can be achieved in the heat exchange system.
One is a hollow concrete sphere representing the storage tank and the other is the cylindrical technical unit holding the pump turbine, a controllable valve and the components of the Supervisory Control and Data Acquisition (SCADA) system. The technical unit is removable and can be recovered separately, which facilitates maintenance and repairs.
