Deep sea pumped hydro storage is a novel approach towards the realization of an offshore pumped hydro energy storage system (PHES), which uses the pressure in deep water to store
Fig. 6, Fig. 7, Fig. 8 shows that large scale subsea energy storage systems can be located worldwide. However, the energy density is only one of many factors deciding if a location is suitable for SPHS systems, data with regards to power-supply/demand, infrastructure also affects the feasibility of the concept.
Being able to utilize the ocean for energy storage would also make it possible to co-locate energy storage with deepwater offshore renewables. With current planned offshore energy hubs in the North Sea , co-located energy storage will facilitate the distribution of export power while reducing the curtailment of power.
Seawater PHS stores energy by pumping seawater into elevated reservoirs on land and although seawater PHS increases the number of suitable locations for PHS, great care needs to be taken as the biosphere on land can be disrupted with the introduction of saltwater.
Case study of storing offshore wind energy in Tokyo, Japan. The world is undergoing a substantial energy transition with an increasing share of intermittent sources of energy on the grid such as wind and solar. These variable renewable energy sources require an energy storage solution to allow a smooth integration of these sources.
The authors would like to thank Subsea 7 and the Norwegian Research Council (Grant number 320663) for providing funding for research into subsea energy storage. In particular, the supervision provided by Dr. Karunakaran (Subsea 7/UiS) has proven to be critical to the progress of the research.
As it can be seen, the BEST system that can store the most energy is the one that starts at 1000 bars (maximum depth of around 10,000 m) and stops at 300 bars (minimum depth of around 3000) for both air and hydrogen as compressed gases.
