Invinity Energy Systems rose 36.1% to 30.6p after it was selected by FlexBase to design a GWh-scale vanadium flow battery for the Technology Centre Laufenburg.
The engineering phase is expected to take place during 2026 and into 2027, will generate engineering revenue for Invinity subject to achievement of development milestones, and is anticipated to be followed by a purchase order allowing phased manufacturing; the project broke ground in May 2025 and is currently under construction, and Invinity is a world-leading manufacturer of vanadium flow batteries.
“Having just delivered the biggest vanadium flow battery in the UK, Invinity now enters the engineering phase of what will be the world's largest vanadium flow battery to date,” Jonathan Marren, Chief Executive Officer, said.
The battery will integrate with an AI datacentre and technology campus on the Switzerland-Germany border to support renewable integration and provide grid stabilisation, and FlexBase said it chose Invinity for the lowest life-cycle costs, safety and modular solutions.
Further announcements will be made as the project progresses and Invinity expects to receive a purchase order following successful completion of the engineering design phase.
