More Gigafactories crucial to securing the future of UK car production

17 May 2021

The UK must rapidly accelerate the establishment of Gigafactories and new battery technology development, or risk losing domestic car production altogether, according to a report published by manufacturing consultancy HSSMI.

“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 140GWh in battery cell capacity, equivalent to five Gigafactories. Currently however, there is only 3GWh of production in the UK and, by 2030, just a further 45GWh planned, leaving a major gap – over 95GWh – 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, optimisation 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 percent – 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 commercialisation 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.”

Another area where HSSMI’s experience can pay dividends is in supporting 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 commercialise 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 programme and speeding up the time to market.” 

HSSMI has laid out five key steps for the UK industry to accelerate Gigafactory creation: 

1. Make the most of what exists already 

Developing products that can fit into existing production facilities or use off-the-shelf machines will enable easier uptake of new cell technology. Where new processes are created, a further development programme will be required for the manufacturing machines, potentially delaying commercialisation.

2. Know your target market

The design of a new battery must be focused on all the needs of the application. While development may target one parameter, e.g., high-capacity chemistry, application requirements for other aspects (cell size, electrode specification) can lead to late design changes, extra costs through revalidation trials, equipment re-tooling or replacement.

3. Understand the costs involved

Materials used in lithium-ion cells are expensive, so high process yields are critical. Taking steps towards optimised production early in product development is key to keeping lab-to-production timescales minimal and reduce waste material costs during upscaling activities.

4. Conduct manufacturing feasibility studies early 

Feasiblity studies are important to understand Gigafactory-specific characteristics, facility requirements (size, utilities, labour) and how the product selected for manufacture influences them. Unique cell design features that increase production time or complexity could lead to non-profitable products. Early studies facilitate parallel development of the product for performance and manufacture to ensure commercial viability.

5. Engage with scale-up specialists

Specialists can address many challenges swiftly, saving time and money, through leveraging existing supplier relationships, equipment knowledge, facility design and scale-up experience.

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 catalysing innovation and collaboration between manufacturers, technology providers, automotive OEMs, research organisations, and academics, through various funding opportunities.”

HSSMI believes it is critical that the government continues to back the work of these organisations 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 percent (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."
