The European Marine Energy Centre (EMEC) will be deploying flow batteries at its tidal energy test site on the Island of Eday. This will be a first of its kind project, where tidal power will be combined with vanadium flow batteries, and will be used to power EMEC’s hydrogen production plant, demonstrating continuous hydrogen production from variable renewable generation. The project gets £1.8 million funding from the Scottish Government, via Highlands and Islands Enterprise (HIE) and will consist of eight Invinity VS3 battery modules linked together into a single system of 1.8MWh. EMEC selected Invinity’s flow batteries for this application due to their ability to perform multiple cycles per day without degradation. This is due to variability of tidal generation, with two high and two low tides occurring each day, which would be harder for technologies like Lithium-ion as heavy cycling required would lead to its faster degradation. According to EMEC and Invinity, the project is expected to go live next in 2021.
