In a press release published on 27 September 2026, the Department for Business, Innovation, Science and Trade said Geothermal Engineering Limited had received an Offer in Principle worth nearly £10 million through the DRIVE35 Automotive Transformation Fund to support a £43 million lithium extraction facility in Cornwall. The department said the project would create nearly 50 direct roles and support around 80 further jobs across the supply chain. (gov.uk) The government is presenting the scheme as part of a wider industrial policy push to secure domestic access to critical minerals used in electric vehicles, clean energy systems and advanced manufacturing. The policy point is less about one site alone and more about whether public funding can move strategically important inputs closer to UK vehicle and battery production. (gov.uk)
The announcement matters because government now treats lithium as a supply-chain security issue as well as a mining or energy issue. In Vision 2035: Critical Minerals Strategy, the government says annual UK demand for lithium is expected to rise by 1,100% by 2035 and sets an ambition for at least 50,000 tonnes of lithium, or lithium carbonate equivalent, to be produced domestically by that date. (gov.uk) The same strategy says the UK wants at least 10% of total critical mineral demand to be met through domestic production, 20% through recycling, and no more than 60% of aggregate annual demand to come from any one country by 2035. Read against those targets, Cornwall is not simply a regional development story; it is an attempt to add domestic volume to a market where government sees concentration risk in global processing and trade. (gov.uk)
DRIVE35 is the funding vehicle behind the offer. According to the programme guidance, DRIVE35 provides £4 billion of capital and research-and-development funding to 2035 for zero-emission vehicle manufacturing and supply-chain components, with the Automotive Transformation Fund acting as the capital-only Transformation pillar. Eligible activity includes batteries, new plants, upstream supply-chain projects and recycling. (gov.uk) That matters because the Cornwall project sits several stages upstream from vehicle assembly. In plain English, the state is not only supporting final car production; it is also trying to reduce exposure at the raw-material and processing end of the chain. The funding announcement remains provisional, however: the government states that the Offers in Principle for Geothermal Engineering and Tees Valley Lithium are still subject to due diligence and final approvals, and ministers retain discretion over final awards. (gov.uk)
The Cornwall offer is one half of a broader package. The same government statement says Tees Valley Lithium has a DRIVE35 Offer in Principle worth £18.3 million backing a £185 million refinery investment in Teesside, taking the two lithium projects together to nearly £230 million of planned private investment. Tees Valley Lithium is intended to establish one of Europe’s largest lithium refineries and, like Cornwall, is presented as a step towards a more domestic battery materials chain. (gov.uk) The timing is also political. Four days earlier, on 24 September 2026, the department said automotive investment announcements from Bentley, McLaren and Nissan totalled £1.02 billion between 16 and 23 September. The Cornwall announcement therefore sits inside an existing government narrative that pairs industrial strategy, electric vehicle manufacturing and regional job creation. (gov.uk)
Although ministers describe the development as a new mine, the department says commercial output is expected to come from geothermal brine underground. Production is scheduled to begin in 2029, with expected output of about 1,500 tonnes of technical-grade lithium carbonate a year - enough, according to the government, for more than 180,000 typical electric car batteries. The statement also says the facility could expand to far higher volumes over time. (gov.uk) The immediate policy value is resilience rather than scale. The Cornwall plant would add a domestic source of lithium compound, but it would not by itself remove the need for further refining, cathode and cell production, or vehicle assembly capacity elsewhere in the chain. On a reasonable reading of the package, the pairing of Cornwall extraction with Teesside refining is the more meaningful signal, because DRIVE35 is explicitly designed to support both zero-emission vehicle manufacturing and upstream supply-chain components. (gov.uk)
There is also a regional policy point. Ministers and industry figures are using Cornwall’s mining history to argue that critical minerals can support present-day manufacturing growth in the South West, while APC and Zenzic have described the project as part of a developing materials cluster in the county. For local government, training providers and suppliers, the next issues are practical ones: whether due diligence completes, whether the site reaches commercial production in 2029, and whether the project can secure the skills, infrastructure and long-term offtake needed to expand beyond its initial output. (gov.uk) The clearer reading is that this is an industrial policy intervention rather than a simple mining announcement. The government is using provisional grant support to draw private capital into an early-stage critical minerals project, with the aim of strengthening EV supply chains and keeping more value from extraction and processing inside the UK. Whether that approach succeeds will depend less on the headline grant figure than on project delivery, follow-on processing capacity and final ministerial approval. (gov.uk)
