Siemens and Vulcan Energy are collaborating to advance the Lionheart lithium and renewable energy project in Germany’s Upper Rhine Valley, Europe's first fully integrated lithium and renewable energy project.
Vulcan Energy has also designated Siemens its preferred supplier of automation and digitalisation technology until 2035.
Backed by the European Investment Bank (EIB), Vulcan’s integrated lithium and renewable energy project adapts existing, commercially proven technology to produce battery-quality lithium from geothermal subsurface brine in the Upper Rhine Valley, to deliver a local source of sustainable lithium for the European battery industry, while generating renewable energy and heat for local communities.
Lionheart targets production capacity of 24,000 tons of lithium hydroxide monohydrate (LHM), enough for around 500,000 electric vehicle batteries per annum, with a co-product of 275 GWh of renewable power and 560 GWh of heat per annum for local consumers, over an estimated 30-year project life.
Siemens will provide comprehensive automation and digitalisation capabilities through the delievery of end-to-end project solutions from its Xcelerator portfolio – including advanced instrumentation, distributed control systems, digital twin technology, industrial network, IT security and analytics that will enable integrated operations from resource extraction to final production. Siemens will also provide smart infrastructure solutions from across its buildings portfolio. The company is addionally investing in the Lionheart project.
“As both a strategic investor and a key technology partner, we are helping Vulcan Energy establish Europe’s first major sustainable source of lithium,” said Roland Busch, President and CEO of Siemens AG. “With our technology – from advanced automation and digitalisation to smart building solutions – we help to ramp-up production faster. This is essential to create a local lithium supply for our energy transition and a more competitive, resilient and sustainable European industry. It is a powerful example of strengthening growth and competitiveness in line with the Made for Germany initiative.”
“This partnership is an important step in unlocking future opportunities for growth, as we progress toward our goal of decarbonising Europe’s battery supply chain,” commented Cris Moreno, Vulcan’s Managing Director and CEO.

Energy resiliency and security of supply are two driving forces that could add momentum to the geothermal sector across Europe, amid oil and gas price spikes triggered by the Iran conflict in the Middle East.
In the UK, wind and solar blunted the worst of the price shocks in the first four weeks of the current fossil fuel crisis by displacing gas generation, delivering critical cost savings, according to a new report by Ember Energy.
It stated that new wind and solar saved Britain approximately £7mn per day in gas purchases.
The international price of gas surged in March 2026 following the start of the US-Israel war with Iran on 28 February, initiating the second fossil fuel crisis in Europe in just four years, after the Russia-Ukraine conflict.
As a result of new wind and solar capacity, in March 2026 gas power generation was 39% lower than in March 2021.
“The latest fossil fuel crisis proves that wind and solar have already lowered our dependence on gas and delivered genuine savings,” said Josie Murdoch, Energy Analyst, Ember.
“We now need to deploy more renewables and reduce our reliance on volatile gas for good.”
While the report does not explicitly cite geothermal, it claims that Britain is “better insulated” since the 2021-23 energy crisis.
As well as providing ‘unblockadable’ energy, geothermal can also deliver consistent 24/7 baseload power, unlike more intermittent solar or wind, making it attractive in terms of security of supply and resiliency.
Since October 2021, Ember said over 130 wind and solar projects have been delivered — 7.7 GW of new wind power (onshore and offshore, including floating) and 7.6 GW of new solar power.Britain now has close to 55 GW of wind and solar capacity, leading to higher renewable generation and increasingly displacing gas in Britain’s power system, it noted.
More broadly, across the European Union, analysis shows the cost of gas-fired power increased by more than 50% in the first 10 days of the Iran conflict, with some countries, such as Italy, more affected than others.
In a February 2026 report, Ember suggested that geothermal could replace 42% of the EU’s coal and gas-fired generation, providing a stable, ‘always-on’ alternative to fossil fuels for less than €100/MWh – the cost of coal and gas electricity.
“Once restricted to a few geological hotspots like Iceland or Tuscany, modern geothermal is now cost-competitive with gas across much of the continent,” said Tatiana Mindekova, Ember Policy Advisor and author of the February report.
“As Europe seeks to slash emissions while meeting the energy demands of heavy industry and AI data centres, this untapped resource offers a clean, firm power supply that remains insulated from the price volatility of imported fossil fuels.”
Vallourec, supplier of premium tubular solutions for the energy industry, and Fervo Energy, the global pioneer of next-generation geothermal energy, have signed a five-year supply agreement worth up to US$800mn whereby Vallourec will act as Fervo’s exclusive supplier of U.S. manufactured tubular solutions and VAM connections through its distribution partner Sooner, Inc.
Vallourec will provide a wide range of premium tubular solutions engineered for the temperature conditions of next-generation geothermal wells, including its VAM high-torque semi-flush connections – originally developed for shale applications and now proven in geothermal environments.
The deal illustrates the potential for transferring and adapting technology and expertise from the oil and gas sector, also characterised by extreme high temperature environments, to the fast-growing geothermal sector. Ensuring long-term geothermal well integrity at high temperatures is a key challenge for geothermal developers.
The collaboration will establish a fully domestic supply chain for critical geothermal well infrastructure at a time when investment in next-generation geothermal has accelerated rapidly, driven by a rising demand for baseload, carbon-free power to support electrification and data centre expansion. Vallourec has in fact seen an increase in demand for its geothermal products increase more than three-fold.
The deal supports Fervo’s strategy to deploy repeatable GeoBlocks – standardised 50 MW units of geothermal energy, as it scales its operations. It follows Fervo’s signature of a supply deal with Turboden America for the supply of ORC turbines for up to 35 GeoBlocks, also designed to strengthen the US supply chain for geothermal development.
Philippe Guillemot, chairman of the Board of Directors and chief executive officer of Vallourec, commented, “Our model of low-carbon, vertically-integrated production hubs located close to our markets is paired with our strong focus on innovation and tailor-made technological solutions in making Vallourec a key strategic partner for customers like Fervo. We look forward to supporting the development of next-generation geothermal energy needed to power the rising electricity demands, in particular due to the hypergrowth of data centres in the United States of America.
Tim Latimer, chief executive officer of Fervo Energy added, “Delivering next-generation geothermal at scale requires precision, reliability, and strong collaboration across the supply chain. Vallourec brings deep expertise in manufacturing low-carbon, high-performance tubular solutions that will play a critical role in enabling the rapid buildout of GeoBlocks at Cape Station and beyond."
Expro has secured a Tubular Running Services (TRS) contract with Lithium de France to support new geothermal and direct lithium extraction wells in Alsace.
A geothermal heat pump has been installed at the site of Nelt Group, a leading logistics company in Serbia, as part of efforts to curb environmental impact.
The new geothermal system at the Dobanovci distribution hub will reduce greenhouse gas emissions by 40% by 2030 and save 7 million kWh of energy annually, according to a statement by the European Union (EU) mission to Serbia.
Serbia is not an EU member but provided support for the project — together with the Swiss government, with a US$200,000 donation — as part of the ‘EU for Green Agenda in Serbia’ initiative.
“The European Union stands with Serbia on the path of green transition. We support the adoption of cleaner technologies, better environmental management and progress toward a greener, more sustainable, and competitive economy,” said Andreas von Beckerath, Ambassador of the European Union to Serbia.
“Nelt’s example shows that renewable energy can replace fossil fuels in complex logistics operations while simultaneously contributing to both environmental and economic goals.”
The hybrid water-to-water system replaces a gas boiler and provides heating and cooling for two large halls with warehouse and office spaces, and a technical block for vehicle servicing.
It will provide about 40% of the total energy required for these facilities and operates in combination with the existing solar power plant.
“Our long-term commitment is to develop the company responsibly and sustainably through initiatives that deliver measurable and concrete results,” said Marko Cilić, Chairman of the Executive Board and Acting CEO of Nelt Group.
“The geothermal system in Dobanovci has been designed with a clear development perspective and will be an integral part of future logistics capacities, connected to the new warehouse within the centre.”
Anne Lugon-Moulin, Ambassador of Switzerland to Serbia, added: “The project with Nelt clearly shows how innovative solutions can contribute to reducing harmful emissions and improving energy efficiency, and demonstrates that companies can be both competitive and environmentally responsible.”
