Cornish Lithium Secures £35M to Advance Geothermal Lithium and Critical Mineral Projects in the UK

Cornish Lithium Secures £35M in Equity Funding A Milestone for UK Critical Minerals

In a major boost for the UK’s domestic battery supply ambitions, Cornish Lithium has announced that it has secured £35 million in new equity funding. This capital raise is intended to propel its key projects closer to construction and commercial stages, marking a pivotal moment in the firm’s trajectory.

Backing & Investors

The funding round is led by existing institutional backers, with up to £31 million coming from the National Wealth Fund(NWF), and approximately £4 million from TechMet, a long-standing investor in the company. Cornish Lithium’s legal counsel for the deal was Mayer Brown.

What the Funds Will Be Used For

Cornish Lithium will allocate the capital toward advancing two flagship projects:

Trelavour Lithium Project: The funds will support further engineering work, feasibility studies, and help lead the project toward a construction decision.
Cross Lanes Geothermal Lithium Project: The company aims to press ahead with commercial drilling, combining geothermal energy with lithium extraction.

These steps are intended to de-risk the projects and bring them closer to full production capability.

In addition, Cornish Lithium plans to launch a crowdfunding round via Crowdcube, giving wider shareholders and supporters a chance to participate in its next growth phase.

Conditions & Next Steps

The investment is subject to certain conditions, including:

Shareholder approval at a General Meeting on 8 October 2025
Sign-off from the UK Takeover Panel
Compliance with the National Security and Investment Act 2021

If all goes to plan, Cornish Lithium expects to unlock momentum toward commercial production and strengthen the UK’s supply of lithium, a critical component in battery manufacturing.

Significance & Broader Impacts

This funding round is more than a financial milestone it reflects the increasing importance of critical minerals sovereignty and green industrial strategy in the UK. As demand for lithium used in electric vehicles, energy storage, and electronics continues to surge globally, securing domestic sources becomes strategically vital.

In the words of founder and Executive Chairman Jeremy Wrathall, the investment:

“marks an exciting step forward for Cornish Lithium as we move closer to construction decisions at our flagship projects.”

Ian Brown, interim CEO at NWF, added:

“A resilient domestic supply chain of lithium is critical as we transition towards net zero. Our financing will help Cornish Lithium progress towards commercial production, creating good year-round jobs, boosting local economic growth…”

And from TechMet’s side, the view is similarly ambitious Cornish’s projects will play a role in supplying lithium not only for the UK, but potentially for markets in Europe and the U.S.

Challenges & Risks to Watch

While the funding is a strong vote of confidence, there are a few caveats worth keeping in mind:

Permitting and regulatory risk: The projects still need various approvals under national security and investment regulations.
Technical and geological risk: Scaling mining, extraction, and processing of lithium especially in temperate climates using geothermal or other novel techniques is complex.
Market dynamics: Lithium prices, supply chain competition, and global policy shifts can all influence commercial viability.
Execution risk: Turning advanced studies into operating mines/plants is capital-intensive and operationally challenging.

Final Thoughts

Cornish Lithium’s £35M funding round signals strong institutional support and a critical step toward maturing its Cornwall-based lithium ambitions. If successful, these projects could contribute significantly to the UK’s aspirations for a domestic battery supply chain, adding value locally and strengthening energy transition resilience.

Blowout at Cape Station: Fervo Energy’s First Major Crisis After Blockbuster IPO

Just weeks after a record-breaking IPO, the flagship project of the "geothermal unicorn" faces its first major operational crisis. By : Robert Buluma Beaver County, Utah – The morning of May 27, 2026, began like any other at the Cape Station construction site in rural Utah. Workers for Fervo Energy, the newly public darling of the renewable energy world, were engaged in the complex task of drilling deep into the Earth’s crust to unlock what the company promised would be the future of 24/7 clean power. But by the afternoon, the routine had turned into a crisis. The site had experienced a blowout—an uncontrolled release of fluid or pressure from a well. For any energy company, a blowout is a serious matter. For Fervo Energy, which had just raised $1.89 billion in a blockbuster Nasdaq debut two weeks prior, it represents an immediate stress test of its technology, its safety protocols, and its $7.7 billion market valuation. While the well has since been contained and no injur...

Rodatherm Energy: The Refrigerant Gambit

By: Robert Buluma Rodatherm Energy has done something no other geothermal startup has attempted at commercial scale: swapped water for refrigerant in a closed-loop system. The claim is 50% higher thermal efficiency than water-based binary cycles, achieved by circulating a proprietary phase-change fluid through a fully cased, pressurized wellbore. The company emerged from stealth in September 2025 with a $38 million Series A—the largest first venture raise in geothermal history. Lead investor Evok Innovations was joined by Toyota Ventures, TDK Ventures, and the Grantham Foundation. The engineering thesis is elegant. The execution risks are significant. This is an Alphaxioms examination of both. II. The Thermodynamic Distinction Every geothermal company you've covered moves heat using water or steam. Rodatherm moves heat using a fluid that boils and condenses inside the wellbore. In a conventional closed-loop water system (Eavor's model), water circulates as a single-phase liq...

The Retrofit Revolution: How GreenFire Energy Is Turning Abandoned Oil & Geothermal Wells Into Continuous Clean Power Without New Drilling

The Retrofit Revolution: How GreenFire Energy Is Unlocking Geothermal Power Without Drilling a Single New Well By: Robert Buluma While much of the geothermal energy sector has been focused on breakthrough drilling techniques—deeper wells, hotter reservoirs, and complex engineered systems—a quieter revolution has been unfolding in the background. Instead of chasing entirely new subsurface frontiers, one company has chosen a radically simpler question: What if the answer was already in the ground? GreenFire Energy is advancing a retrofit-first geothermal strategy that targets one of the most overlooked opportunities in the global energy transition: existing wells that are underperforming, depleted, or completely abandoned. Rather than drilling new holes into the Earth, the company is reusing the infrastructure that already exists—turning stranded assets into continuous sources of clean, baseload electricity. This approach is not just technically elegant. It may also be one of ...

Eavor Geretsried Geothermal Breakthrough: Inside the Closed-Loop Energy Revolution, Drilling Challenges, and Path to Scalable Clean Power

The Geothermal “Holy Grail” Just Got a Reality Check: Inside Eavor’s Geretsried Breakthrough By: Robert Buluma May 22, 2026 It’s not every day a deep-tech energy company publishes a detailed technical report that openly documents what went wrong on its flagship project—and still comes out looking stronger. That’s exactly what Eavor Technologies did with its Geretsried geothermal project in Bavaria, Germany. The result is unusually transparent: part technical post-mortem, part validation of a technology many have doubted for years. And the core message is simple. They built it. It works. But it wasn’t smooth. The short version Eavor is trying to solve one of geothermal energy’s hardest problems: how to produce reliable heat and power anywhere, not just in rare volcanic hotspots. Their claim has always been bold: a closed-loop geothermal system that is scalable, dispatchable, low-carbon, and independent of natural reservoirs. Critics have long argued it wouldn’t survive...

The XGS Energy Heat Sponge Solves Geothermal's Biggest Problem

The XGS Energy Heat Sponge Solves Geothermal's Biggest Problem I mage: A californian XGS well pad Imagine drilling a hole into the Earth’s hot crust but instead of simply dropping in a pipe and hoping for the best, you paint the inside of that hole with a magic material that soaks up heat like a sponge soaks up water. Then you seal it, circulate a fluid, and generate clean, firm electricity 24/7, no fracking, no water consumption, no earthquakes. That’s not science fiction. That’s XGS Energy . While most of the geothermal world has been chasing fracked reservoirs or massive drilling rigs, XGS quietly built a prototype, ran it for over 3,000 hours in one of the harshest geothermal environments on Earth, and landed a 150 MW deal with Meta – enough to power tens of thousands of homes or a massive data center campus. This is the story of a technology that might be the most elegant, low-risk, and capital-efficient path to scalable geothermal power. Let’s dig in. Part 1: The Pro...

Sage Geosystems: Turning Underground Pressure Into 24/7 Power

Sage Geosystems : The Geothermal Startup That Turns Pressure Into Power By: Robert Buluma Most conversations about advanced geothermal circle around the same question: How do you extract heat from dry rock? Sage Geosystems started with a different question: What if the Earth could do most of the work for you? Based in Houston, Sage has quietly built a technology stack that treats the subsurface not just as a heat source, but as a pressure vessel. Their system captures heat and mechanical energy, stores energy underground like a battery, and uses a fraction of the surface pumping that conventional geothermal requires. This article focuses entirely on Sage , how their technology works, what makes it genuinely different, and where the blind spots still are. Part I: The Core Innovation , Pressure Geothermal Sage's foundational insight is simple but powerful: deep hot rock isn't just hot. It's also under immense natural pressure. Traditional geothermal systems ignore that pre...

Project Obsidian: Unlocking Superhot Geothermal Power from Deep Earth

Quaise Energy and the Dawn of Superhot Geothermal Power in Oregon By: Robert Buluma Inside Project Obsidian and the Future of Deep Earth Energy The global energy transition has long been defined by solar panels on rooftops, wind turbines across plains, and batteries reshaping grids. Yet beneath all these familiar technologies, another contender is quietly emerging—one that does not depend on weather, daylight, or even surface conditions at all. It comes from deep within the Earth itself, from rock so hot it behaves almost like a molten energy reservoir. That is the frontier where Quaise Energy is now operating. In Oregon, the company is developing what could become the world’s first superhot geothermal power plant under its ambitious initiative known as Project Obsidian . If successful, it could mark a fundamental shift in how humanity produces clean, continuous electricity—moving from shallow geothermal pockets to tapping heat sources several kilometers beneath the Earth’s surfac...
