‘UK must urgently build EV battery Gigafactories or risk losing its car production’, report claims

Not only is the UK and its automotive industry in the middle of a huge challenge to be ready for the government’s ban on gas and diesel car sales by 2030, beyond that it is predicted to be facing a worrying shortfall of battery production as the country switches to electric vehicles.

A report from manufacturing consultancy HSSMI highlights the UK’s urgent need to build more EV battery Gigafactories as its trajectory predicts that by 2040 the country will be lacking more than 95GWh of cell production required to sustain the demand for EVs domestically. The report claims the worst-case scenario could result in the UK potentially losing its domestic car production.

“Electrification is increasing demand for the battery cells and packs powering electric vehicles,” said Axel Bindel, Executive Director, HSSMI. “The UK, in particular, is at a pivotal moment. By 2040, there will be a need for 140 GWh in battery cell capacity, equivalent to five Gigafactories. Currently, however, there is only 3 GWh of production in the UK and, by 2030, just a further 45 GWh planned, leaving a major gap – over 95 GWh – between the rate of battery plant establishment, planning and the forecasted demand. That is where HSSMI can play a crucial role.”

HSSMI advises global OEMs and Tier 1 suppliers on the design of manufacturing plants, optimization of production efficiency and introduction of circular economy principles. In recent years, it has amassed a wealth of knowledge in Gigafactory development, expertise which has never been more crucial, as the UK – as well as Europe and the US – risk being left behind by other countries that are making rapid headway towards electrification.

With its accessibility to abundant natural resources, as well as government-driven support for high volume manufacturing and local demand for electric vehicles, the majority of global battery production – roughly 70 per cent – is currently in Asia.

The UK on the other hand, faces challenges including lack of skilled technicians on cell manufacturing processes and availability of critical raw materials, as well as high production costs. Investing in more battery plants and bringing them as close as possible to car production – reducing supply chain challenges – can alleviate many of these issues, but the industry needs to act fast. It is clear that the government is starting to make funds available for the industry, with more collaboration potentially needed to steer the country to success.

“Over the past three years, HSSMI has worked on cell manufacturing and Gigafactory projects and our existing knowledge allows us to assist OEMs and Tier 1s in getting these new facilities opened faster,” continued Robin Foster, Battery Solutions Lead at HSSMI. “Typically, it could take a Gigafactory up to five years from an initial idea to become fully operational. Demand for cell manufacturing, however, is expected to surge in the next four to five years. Our expertise in cell design, manufacture and commercialization can dramatically speed this up, not to mention our network of some of the largest stakeholders in the industry, which brings us a step closer to creating a fully-formed supply chain.”

HSSMI also supports decision-making and planning in the development of new battery technologies and its acceleration onto the market. “It is not enough to have one or the other – we can’t focus just on Gigafactory creation without being strategic about new technologies,” added Robin. “So, in parallel, the UK must exploit and commercialize the wealth of new battery technology developed locally. The typical time, however, for new technology to become commercially ready can be 10 years from lab to high-volume production. Engagement with a scale-up specialist can provide feedback early on for commercial viability, disrupting the traditional linear development program and speeding up the time to market.”

Trends are already emerging with automotive OEMs partnering with cell manufacturers and entering into joint ventures to secure battery cell supply. Staying close to cell manufacturers allows automotive OEMs to eliminate supply chain risks, such as concerns about transporting dangerous goods and longevity of supply, and use the opportunity to co-develop battery cells, packs and EVs. HSSMI believes it is imperative for the UK to attract and develop high volume cell manufacturing capability to decrease the temptation for domestic automotive OEMs to seek opportunities elsewhere.

“At the moment, the Envision AESC facility in Sunderland is the only UK facility manufacturing lithium-ion cells at scale (2-3GWh). AMTE Power and BritishVolt have both announced plans for UK-based Gigafactories, which will help supply local products to the UK automotive sector,” added David Stewart, Engineering Director, Research & Innovation, HSSMI. “Nonetheless, further investment into the UK automotive industry is crucial, as it has been plummeting since 2013 and in 2018 inwards investment amounted to only £0.59 billion. Government-backed bodies such as the Advanced Propulsion Centre and the Faraday Institution are continuously working to accelerate battery technology by promoting and catalyzing innovation and collaboration between manufacturers, technology providers, automotive OEMs, research organizations, and academics, through various funding opportunities.”

HSSMI believes it is critical that the government continues to back the work of these organizations and that R&D funding is channelled into the automotive industry.

“Action to ramp up capacity needs to be taken within the coming year,” said Axel Bindel. “In the most detrimental scenario, UK-based automotive OEMs would seek to leave the country. This would adversely affect the entire economy, not just the automotive sector, as it accounts for 14.4 per cent (worth £44 billion) of total UK exports of goods. But with close collaboration between investors, customers, government, technology developers and suppliers, the challenges can be overcome to provide competitively priced, high quality, high performance, even potentially world leading, battery cells. And HSSMI has a crucial part to play in this solution.”
