Invinity Threatens Departure Over Policy Outcomes

Invinity Energy Systems, a prominent UK manufacturer of vanadium flow batteries with facilities in Motherwell and Bathgate, Scotland, has issued a stark warning that it may quit the UK. The company's frustration stems from the outcome of Ofgem's long-duration energy storage (LDES) cap-and-floor scheme, where it lost out to a Chinese firm. Critics argue the scheme unfairly favored lithium-ion batteries over true long-duration technologies.

Concerns Over Domestic Manufacturing and Jobs

Scottish Labour MP Kirsteen Sullivan is actively urging the UK Government to intervene and support domestic energy infrastructure. Her primary goal is to secure up to 1,000 potential green manufacturing jobs at Invinity's Scottish sites. Sullivan emphasized that energy security is fundamentally national security, highlighting the severe risk to local communities if the firm decides to relocate its operations overseas.

Energy security is national security, and the loss of domestic LDES manufacturing capabilities would severely undermine the UK's resilience and green industrial strategy.

National Wealth Fund Investment and Market Realities

Adding to the complexity, the taxpayer-owned UK National Wealth Fund recently provided £25 million in public investment to Invinity to develop its vanadium flow battery technology. However, the firm warns that this capital injection may not be enough. Without the guaranteed minimum income provided by the Ofgem cap-and-floor scheme, Invinity could be left without sufficient domestic orders to sustainably expand its operations.

This situation underscores the critical need for policy frameworks that accurately value the unique attributes of long-duration energy storage. If the UK fails to create a level playing field for vanadium flow batteries, it risks losing its emerging LDES supply chain to international competitors, ultimately compromising its long-term energy transition goals.
