Battery Futures Series - Part 2: From innovation to industrial impact: solving the UK's scale-up challenge

The scale-up gap

The UK does not have an innovation problem. It has a commercialisation problem. Across the showcase, industry leaders, investors, researchers and innovators repeatedly returned to the same question: how do we move from world-class research, internationally respected universities and a strong innovation ecosystem to scaling battery technologies into successful industrial businesses?

The UK has produced breakthrough technologies, pioneering materials innovations and exciting battery start-ups. However, moving from laboratory development to commercial deployment remains one of the most difficult phases of the innovation journey. Our network described a landscape where technical readiness often progresses more quickly than investment, market or manufacturing readiness.

There are multiple reasons for this. Battery businesses are usually capital intensive. Manufacturing equipment is expensive. Development timelines are long. Performance testing takes time. Market adoption often depends on customers changing established products, approaches or practices. Even when the technology works, commercial traction can be slow to develop.

Bridging the valley of death

The “valley of death” that exists between research and industrial deployment remains a challenge. At lower technology readiness levels, innovators may access academic funding and early-stage grants. At the other end of the spectrum, mature businesses with proven revenues can attract private investment. Between those points lies a difficult middle ground where technologies are too advanced for research funding but still too risky for commercial investors. Bridging this gap requires more than just finance.

Investment is, of course, critical and access to capital was consistently identified as a major challenge by both companies and investors. However, demonstration facilities, manufacturing infrastructure, testing capabilities, customer engagement, and long-term demand signals are of equal importance. Successful commercialisation depends on an ecosystem, not a single intervention.

Building markets alongside technology

Businesses ultimately need customers and investors need confidence that markets exist, and manufacturers need confidence that future demand justifies investment. The strongest innovations are often those developed alongside real users solving real problems.

This is particularly relevant for emerging battery applications beyond automotive. Defence, aerospace, rail, maritime and grid operators all have complex requirements. Meaningful collaboration between technology developers and end users is therefore essential to ensure innovation addresses actual operational needs rather than hypothetical ones.

Creating confidence across the ecosystem

There is also a broader strategic challenge around confidence.

The opportunity for the UK lies in creating an environment where confidence can grow. Confidence in different technologies. Confidence in supply chains. Confidence in future demand. Confidence in policy direction.

The encouraging news is that many of the building blocks already exist. The UK has a strong research base, internationally recognised facilities, growing innovation programmes and increasing collaboration between industry and government. What is needed now is greater connectivity between those elements and clearer pathways that help businesses move from innovation to industrial impact.

Turning UK strengths into industrial impact

This is where existing UK innovation infrastructure matters. Programmes such as the Battery Innovation Programme can help convene and fund businesses, researchers, investors and end users around common challenges, while networks such as the Cross-Sector Battery Systems Innovation Network provide the connective tissue needed to expose innovators to real market needs. These mechanisms do not remove the scale-up challenge, but they help de-risk it by creating clearer routes from problem identification to collaboration, demonstration and eventual deployment. And Innovate UK’s prospectus shows that the focus is now on turning breakthrough ideas into UK giants.

Ultimately, the UK’s success in batteries will not be determined by how many technologies are invented. It will be determined by how many companies are able to bridge the valley of death from innovation to industrial impact, reaching customers, creating jobs and generating lasting economic value.

In the next article, we explore the demand side of the equation and examine the diverse markets that are driving a new era of battery adoption beyond electric vehicles.
