Fraunhofer IEE, in collaboration with industrial partners, is currently carrying out tests on an innovative underwater energy storage system<\/a><\/strong> . This system uses submerged concrete spheres operating on the principle of hydraulic pumping \u2013 a technology that could revolutionise the energy transition. <\/p>\n\n

Following a successful initial test in Lake Constance, Germany, the test is now taking place off the coast of California, with a 400-tonne, nine-metre-diameter sphere submerged to a depth of up to 600 metres.<\/p>\n\n

Spherical energy storage technology<\/h2>\n\n

This system, called StEnSea (Storing Energy at Sea), stores energy using a hollow sphere that is emptied to charge and filled with water to release energy, similar to pumped storage plants on land. With a power of 0.5 MW and a capacity of 0.4 MWh<\/strong> in this pilot phase, StEnSea storage represents a viable solution for storing large amounts of energy<\/a><\/strong> in the short to medium term in the ocean.<\/p>\n\n

The project is supported by the German Federal Ministry of Economics, with an investment of 3.4 million euros<\/strong> , and by the US Department of Energy, with funding of 4 million dollars. Fraunhofer IEE is working with Sperra, a US start-up specialising in 3D printing of concrete<\/a><\/strong> , and Pleuger Industries, a manufacturer of underwater motor pumps, an essential component of the system. <\/p>\n\n

Projections and global potential<\/h2>\n\n

According to the researchers, this technology could<\/strong> achieve a global storage capacity of 817,000 GWh<\/strong> , with optimal locations in Norway, Portugal and other deep-sea areas. The estimated storage costs would be 4.6 cents per kWh, with a useful life of between 50 and 60 years. The efficiency of this system is between 75% and 80%<\/strong> , which makes it a competitive alternative to conventional storage systems. <\/p>\n\n

Energy stored using the StEnSea system<\/a><\/strong> could help stabilise electricity grids and facilitate the transition to a sustainable energy model, storing electricity when prices are low and releasing it when needed, thus optimising the use of renewable energy at sea<\/a><\/strong> .<\/p>\n\n
