On December 3, 2024, Invinity Energy Systems announced the commercial launch of its next-generation grid-scale flow battery, named 'Endurium'. Designed for large-scale energy storage projects, the Endurium can handle capacities of up to 1 GWh and beyond.
The battery, developed in collaboration with Siemens Gamesa, offers discharge durations ranging from four to 18 hours. It features lower storage costs, enhanced energy density, and simplified maintenance compared to earlier models, while ensuring safety, durability, and longevity.
Invinity's CEO, Jonathan Marren, emphasized that the launch represents a significant advancement in providing low-cost, low-carbon energy on demand. The production of Endurium batteries will take place at Invinity's facilities in Scotland, with first shipments expected before the end of 2024.
Confirmed customers include Gamesa Electric and Everdura Technology Co., and the U.S. Department of Energy has selected the Endurium for 84 MWh of projects. The battery technology also qualifies for the UK government's support mechanism for long-duration energy storage.
Invinity has received investment from the UK Infrastructure Bank and reported an 800% increase in shipments and a 170% rise in its sales pipeline in 2023, with ongoing projects in Australia, Canada, and Orkney.
