"Offshore wind power needs energy storage and power regulation, and Ocean Grazer has invented an offshore energy storage system that will sit at the bottom of the sea and manage the flow of electricity through the power grid.
…
Ocean Battery is based on hydro dam technology that can be deployed at the source of power generation. Excess wind power is routed toward the Ocean Battery that pumps water from its underground reservoirs into the flexible bladders installed at the seabed. Whenever there is a demand for power, water is routed through hydro turbines to generate electricity back into the underground reservoirs.
…
Ocean Grazer claims that Ocean Battery has an efficiency of around 80% and that it should be able to run unlimited cycles for more than 20 years. The company, which announced on January 6 that it has closed a deal with an angel investor, will deploy an onshore Ocean Battery in the Netherlands by 2023 and aims to have an offshore system in place by 2025."
