Vanadium-flow battery technology company Invinity Energy Systems announced on Thursday that the 1.7 MWh first phase of the flow battery at the Energy Superhub Oxford (ESO) project was now installed and energised.
The AIM-traded firm said the battery cluster, comprising nine Invinity VS3 flow batteries, would have enough capacity to serve the daily electricity needs of more than 200 UK households.
It said energising the cluster – the first of three that would ultimately deliver a total of over five MWh, was an “important milestone” in the ongoing commissioning process of what would be the UK’s largest flow battery.
Invinity personnel were currently on site making final preparations for the delivery of the second cluster of VS3s, expected shortly.
The company said it was working with its project partners – developer Pivot Power, part of EDF Renewables, as well as global technology company Wartsila, battery trading platform Habitat Energy and power electronics supplier Gamesa Electric – to commission the full system in preparation for service delivery to the UK grid.
“Energizing phase one of our Energy Superhub Oxford installation is the first step toward demonstrating externally what we ourselves know to be true – Invinity is in a lead position toward providing a compelling alternative to lithium batteries for stationary storage,” said chief executive officer Larry Zulch.
“Persevering in the face of delays from global events, our team’s dedication and focus on moving this vital project towards completion has been an inspiration.”
At 1620 BST, shares in Invinity Energy Systems were up 8.99% at 103p.
