The National Wealth Fund has confirmed a £12.2 million cornerstone equity investment in Invinity Energy Systems, anchoring a £25 million fundraise intended to expand manufacturing capacity and continue development of the company’s vanadium flow-battery technology.
Current status
The transaction was announced on 22nd October 2026. It is not yet unconditional: the National Wealth Fund says the fundraise, including its own investment, remains subject to approval by Invinity shareholders at a general meeting expected in the coming weeks.
The public investment therefore represents a confirmed commitment within a proposed equity raise, rather than completed project expenditure or an awarded grant.
How the £25 million is structured
According to the Fund, proceeds are intended to enhance Invinity’s manufacturing capacity, support research and development and provide working capital for its global sales pipeline.
Manufacturing and technology focus
Invinity develops vanadium flow batteries for grid-scale, commercial and industrial energy-storage applications. The company’s systems are designed to store electricity and release it when required, supporting flexibility as more variable renewable generation connects to power networks.
The announcement says the new capital will support manufacturing capability in Scotland and internationally, alongside further commercial development of the technology. It does not provide a site-by-site spending allocation, construction timetable or guaranteed output increase.
Existing public investment
This is a further round of support rather than the Fund’s first involvement. The National Wealth Fund states that it invested £25 million in Invinity in May 2024, helping the business expand its UK operations and progress commercialisation.
Why this matters
The deal illustrates how public investment can be used as cornerstone capital to attract institutional and retail participation into a UK clean-energy supply-chain business. For public-sector project teams, the wider relevance is the development of domestic energy-storage capability that may support future grid resilience and the integration of renewable power.
It also shows the difference between financing a technology manufacturer and funding a specific public-estate or infrastructure project. The immediate milestone is corporate investment for scale-up; future project deployment will depend on Invinity’s orderbook, customer contracts and delivery.
Next steps
Invinity’s shareholders are expected to consider the fundraise at a general meeting in the coming weeks. If approved and completed, the company can deploy the proceeds across manufacturing, research and development and working capital. The official announcement does not set out a separate application route for public bodies or a timetable for individual project awards.
