Invinity Energy Systems PLC (AIM:IES, OTCQX:IESVF, AQSE:IES) shares soared close to 50% higher in Thursday morning's trade, after it was selected by FlexBase Group to design a GWh-scale vanadium flow battery system for a Swiss technology campus that is set to include an AI data centre.
The project at the Technology Centre Laufenburg on the Switzerland-Germany border will integrate a vanadium flow battery of up to 1.5 GWh capacity, which Invinity said is believed to be the world’s largest to date.
FlexBase is looking to expand the battery solution to 2.1 GWh in later phases. The system will be used to support renewable energy integration at the site and provide grid stabilisation.
Invinity will now move into the engineering phase, which is expected to run through 2026 and into 2027 and generate engineering revenue subject to development milestones.
Following successful completion of that phase, Invinity said a purchase order for the battery system is anticipated, allowing it to begin phased manufacturing of datacentre-optimised VFB modules for the project.
In London, the share gained 10.85p or 45% to 32.84p, and in reached as high as 34p in earlier exchanges.
