On August 19, a 1.8mwh all vanadium redox flow battery (vrfb) was installed and powered on at the emec test site in Orkney Islands, Scotland. This energy storage technology will be combined with tidal power generation to continuously supply green hydrogen in the facilities on the island.

The technology provider invity's full flow battery can provide more stable performance and thousands of duty cycles without attenuation.

The vrfb system "will integrate the power generated by our customers' tidal turbines and help optimize hydrogen production; energy storage solutions such as all vanadium flow batteries are critical to creating a resilient clean energy system in the future.

Vrfb includes 48 invity vs3 battery modules, which are combined with Tidal generators to supply power to the 670kw hydrogen electrolyzer of emec. The all vanadium flow battery system is manufactured at invity's basgate plant in Scotland.
