(Sharecast News) - Battery manufacturer Invinity Energy Systems has secured two new sales totalling 20MWh to Ideona, one of its commercial partners in Hungary, made up of two Endurium systems scheduled for delivery in the first half of 2026.
Invinity said on Friday that the sale was for use in two solar-plus-storage projects, representing its fourth and fifth sales into the Hungarian market, and represented repeat orders from Ideona, which previously purchased a 4 MWh VS3 battery system in September 2025.
The AIM-listed company confirmed a £17m order book for 2026, including £8m of signed committed contracts and £9m of signed uncommitted agreements, noting that the figures reflected continued commercial and operational progress, including lower product costs and a broader product range.
Chief executive Jonathan Marren said: "These follow-on agreements with Ideona are a strong endorsement of both our technology and our execution. Signing repeat agreements which will represent our largest combined sales to date with a trusted European partner reflects the growing role that long-duration energy storage is playing in solar-plus-storage projects across Central Europe.
"We look forward to supporting Ideona as these projects progress to financial close and into delivery during 2026, and to further expanding our partnership as the market for grid-scale long duration energy storage continues to develop."
Invinity also issued a full-year trading update, saying it expected to report around £17m in revenue and project grant income for 2025.
It also added that it remained active in the UK's Long Duration Energy Storage Cap and Floor Scheme, having submitted bids covering up to 16.7GWh of its vanadium flow battery technology.
As of 0800 GMT, Invinity shares were up 1.33% at 19.00p.
