6 FAQs about [Offshore pumped storage concept]

What is marine pumped storage?

The project comprises the development and testing of a novel pumped storage concept for storing large amounts of electrical energy offshore. This marine pumped storage concept utilizes the sea itself as upper storage reservoir and a hollow sphere on the seabed as the lower storage reservoir.

What is pumped Energy at Sea (StEnSEA)?

“Storing Energy at Sea (StEnSea)” is a novel pumped storage concept for storing large amounts of electrical energy offshore. In contrast to well-known conventional pumped-hydro power plants, this concept greatly expands the siting possibilities, and allows for modular construction and ease of assembly.

What is storing energy at Sea (StEnSEA)?

1. Introduction The goal of the project “Storing Energy at Sea (StEnSea)” is to develop and test a novel pumped storage concept for storing large amounts of electrical energy offshore.

What is utility-scale energy storage based on pumped hydro storage?

This paper introduces a utility-scale ESS based on pumped hydro storage (PHS), which is the most prevalent and mature example of medium–large scale energy storage. This commercially proven storage method currently accounts for over 95% of the total storage capacity being utilized in the world .

What is the global share of pumped hydro storage (PHS)?

Studies highlight that the global share of PHS is set to be doubled in size, reaching 325 GW by the year 2050 . 1.1. Pumped hydro storage Conventional PHS stores potential energy by utilizing the difference in height between two vertically separated bodies of water.

How efficient is an underwater energy storage system?

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.
