Absolute Solar and Wind Limited has bought a 0.4 MWh vanadium flow battery from Invinity Energy Systems as part of an integrated solar PV and electric vehicle (EV) project at The Wave, Bristol, an inland surfing facility.

The project will couple two Invinity VS3 vanadium flow batteries with a capacity of 0.4MWh to approximately 3MWp of solar PV at the site. Invinity’s batteries will help meet site loads and support the integration of EV charging infrastructure at the site.
Site preparation is currently underway and the battery portion of the project is expected to be delivered to site later this year. This is Invinity’s second sale to ASAW, which was the principal contractor for the Scottish Water Perth project which launched in 2022.
The Wave recently announced plans to open further sites across the UK and Ireland. Founder Nick Hounsfield said: “From the word go, we said we would use 100% renewable energy – it would have been so wrong for us to be using fossil fuels to power our waves, thereby contributing to climate change and the acidification of the oceans. The plan was always to progress to be able to generate our own energy and to know that this will become a reality this year is a dream come true.”
In a market update Invinity said it has closed sales for more than 31MWh of vanadium flow batteries including sales to strategic customers such as Dawsongroup in the UK, Equans in Belgium and Hyosung in Korea, a first contract with new Taiwanese partner Everdura, and a major project with Indian Energy supported by the California Energy Commission.
It said it has a current order book backlog for 2023 of £22 million and an order book backlog for 2024 of £7.4 million. It expects that to increase during the year. It is awaiting results of BEIS’s Longer Duration Energy Storage Demonstration competition Phase 2 application, announced on 18 January.
