As of 2025, this engineering marvel represents one of Europe's most ambitious solutions to energy storage headaches. Think of it as a massive water-based power bank, but instead of charging your phone, it powers entire cities during peak demand.
[pdf] A pilot study is underway to investigate reinstating the Juktan power station on the Storjuktan lake adjacent to the Umeälven river in Västerbotten, to a pumped storage plant with a potential of up to 380 MW. The decision to invest is planned for 2027 and commercial operation would.
[pdf] The all-vanadium liquid flow independent shared energy storage power station project is a new energy storage technology that meets the requirements of "large scale, large capacity, low cost, long life, and high safety" for large energy storage power stations.
[pdf] The project is being developed by the company's subsidiary, Mönsterås Biogasproduktion AB, which has received an investment support of EUR 14.9 million from Klimatklivet (a Swedish Environmental Protection Agency program), and plans to invest a total of approximately EUR 48.6 million in the project.
[pdf] This 100-megawatt project with an installed capacity of 100MW/400MWh and a total investment of 1.222 billion yuan is the first all-vanadium liquid flow battery shared energy storage power station in China's cold regions.
[pdf] Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only large-scale power plant of its kind.
