On 16 October 2024, the Karlsruhe Institute of Technology (KIT) was hosting not only the LiCORNE project’s M24 consortium meeting, but also its first exploitation workshop. The event brought together a diverse group of stakeholders, with nearly 15 industry guests and members of the External Advisory Board (EAB), to discuss the latest advancements in lithium (Li) extraction technologies.
The workshop began with a welcome address by Dr. Lourdes Yurramendi [the coordinator of the LiCORNE initiative and Project Director at TECNALIA Waste Valorisation, Energy, Climate and Urban Transition], followed by Nader Akil, Operations Manager at PNO Innovation Belgium, who outlines the objectives of the exploitation workshop and provided an overview of the LiCORNE project. Funded by the European Commission, the project aims to develop competitive technologies for Li extraction and recovery from various feedstocks, including ores, geothermal brines and cathode waste materials. Following this introduction, various partners delivered technical presentations, showcasing their innovative approaches and key exploitable results after 24 months from the start of the project.
Regardless the feedstock considered, all these novel technologies share one theme: sustainability. This focus on sustainability translates into exploring research routes that go beyond the current state-of-the-art (SoA), reducing energy and water consumption and the generation of chemical waste:
Beyond technological presentations, the workshop also facilitated discussions with external participants, including members of the EAB and industry representatives. These exchanges provided valuable insights into the industry’s needs and opened up new routes for collaboration. To facilitate future collaborations, PNO presented several funding opportunities that can be used to bring the most promising technologies and the LiCORNE selected flowsheet to a pilot level.
As the project progresses, the focus will shift now towards the benchmarking and selection of the most promising LiCORNE technologies for upscaling to produce ~1 kg of battery-grade Li by the end of the project. This phase aims to shape a path towards larger piloting and future commercialisation.

Among European geothermal sites, the Upper Rhine Graben (URG) has a great potential for a lithium (Li) production from geothermal brines due to its high concentration and the significant water flows exploited by the geothermal power plants in this area.
Despite its great potential, certain gaps in the basic knowledge of the geochemistry of the URG rocks are persisting, as there is scarce conclusive investigation carried out in the past to estimate the Li content as well as the mechanisms of Li recharge in brine. Identifying Li-rich geological units are essential to target areas with higher Li concentrations for exploration and to ensure the sustainability of this resource.
In geothermal systems, hydrothermal fluids circulate through the fractured and porous rock formations, undergoing complex interactions with the surrounding lithology. Various processes, such as leaching, dissolution, and precipitation, can occur and they can significantly influence the concentration of Li in the circulating fluids. Knowing the chemistry of the reservoir rocks could help us understand chemical reactions occurring between the hydrothermal fluids and the rocks and therefore how Li is mobilised and transported into the geothermal brine.
In the LiCORNE project, ESG is conducting detailed geochemical analysis of several core drills including granite, sandstone, and limestone from geothermal wells drilled in Northern Alsace. Researchers finalised the rock sampling task at the beginning of 2024, while the chemical measurements are expected at the end of June, current year.

In total, 57 samples were collected and closely studied, which facilitates understanding of the chemical elements behaviour in the rock before and after the hydrothermal circulation/alteration. Comparing the results of this on-going investigation with the few data available in literature and referring to the Li concentration in URG rocks could reveal an unexpected behaviour of Li in the geothermal reservoir rocks.
After careful analysis of the chemical composition, isotopic analysis of the same rock will follow which will show more accurately potential sources of Li in the geothermal brine.

On Thursday, 16 November, during the 2023 edition of the Raw Materials Week, the twelve EU funded projects that constitute the Cluster Hub ‘Materials for batteries’ gathered for their annual event in Brussels.
The Cluster Hub has been initiated last year during the 7th edition of the Raw Materials Week. The main objective of the meeting was to meet and discuss the latest developments in the participating projects as well as the new challenges and opportunities discovered through the projects’ lifetime. Nader Akil, Operations Manager at PNO Innovation, inaugurated this second edition outlining the motivation behind the hub’s establishment. He underlined the positive reception and sustained interest from various stakeholders keen on joining this initiative.
Discover and/or rediscover the first edition of the Cluster Hub workshop
Co-organised by RELiEF, EXCEED, ENICON and RAWMINA, the event was also the opportunity to welcome the four new members of the Cluster (EXCEED, RAWMINA, METALLICO and CRM-geothermal). the workshop gathered nearly 100 organisations driving the production and the recycling of raw materials for battery applications from primary and secondary resources.
Building on the initial objective of creating an environment that could foster knowledge exchange on different approaches for the recycling and recovery for battery applications, the event focused on three major topics that depict the transversality characterising the projects: the raw materials through research and science, the roles and challenges of industry and market for raw materials, and the raw materials under the scope of sustainability, durability and social acceptance. During this annual meeting, an interactive session led by Anish Patil from TechConcepts and representing the RELiEF project had the objective of Mapping the European battery material recycling landscape – more details to be found below, in the section referring to the interactive session.
The first session was moderated by Sonia Matencio from LEITAT, representing the RAWMINA project. This session had the objective of discussing the raw materials through research and science, under the scopes of mining, refining, processing as well as the battery data. Sonia introduced this topic under the scope of RAWMINA, explaining the integrated innovative pilot system for Critical Raw Materials recovery from mine waste in a circular economy context. To this end, Christophe Aucher, from LEITAT as well, highlighted the need on an open battery passport system to better reflect and account for any adaptations that might be required due to the changing regulatory landscape.
Sonia welcomed afterward Brecht Dewulf from KU LEUVEN and representing ENICON, who discussed the sustainable processing of Europe’s low grade sulphidic and lateritic Ni/Co ores and tailings into battery grade metals. The idea behind this was to show all the potential of Ni/Co resources for Europe.
Xochitl Dominguez from VITO concentrated her speech on gas-diffusion electrocrytallisation (GDEx), a crucial topic for the projects LiCORNE and RHINOCEROS she works with. GDEx is an electrochemical process of reactive precipitation of metals in solution with oxidising or reducing agents produced in-situ by the electrochemical reduction of a gas, in a gas-diffusion electrode. This was followed by Katrin Kieling from GFZ Potsdam, working there for the CRM-geothermal project and shortly explained the challenges of extracting critical raw materials from geothermal fluids. To conclude this first session, Sandra Pavón from Fraunhofer IKTS explained the demonstration of battery metals recovery from primary and secondary resources through a sustainable processing methodology in the METALLICO project.

The annual meeting followed its course with an interactive session led by Anish Patil, which scrutinised stakeholders’ perspectives on the Green Deal Industrial Plan, Net Zero Industrial Act, Critical Raw Materials Act and the European Battery Regulation 2023. Mentimeter facilitated this interactive session, engaging the audience to explore how these policies intersect, complement each other, and identify critical measures and incentives for achieving their objectives.
Over 30 persons participated in the live-poll proposed, which results display the priority to be set on funding and state aid regarding ranking the four pillars of the Green Deal Industrial Plan in order of relevance (followed by skills development, conductive regulation, and open and fair trade). Another major topic regarding the stimulation of investment in net Zero technologies, the majority of answers placed the ‘enhanced skills’ as first priority, shortly followed by facilitating the access to the market.
Lastly, the participants were divided regarding the critical measures to implement in the EU to stimulate investment in building domestic capacities for extraction of critical raw materials (CRMs). Although the majority opted for ‘cutting red-tape and accelerated permitting’, approximately half of the answers evoked uncertainty, which emphasised one more time the need to engage with policy makers as external stakeholders in all projects.
This interactive workshop was followed by two sessions, which aimed at discussing the challenges and opportunities of raw materials within the frame of industry and market, as well as the social acceptance, sustainability, and durability.
Alan Gonzalez from PNO Innovation Begium, representing LiCORNE, moderated the industry part, whereas Sam Hoefman from RELiEF moderated the last session on social acceptance, sustainability, and durability. Distinguished panellists took the stage to engage in debates on various topics.
Edvarts Emerson, Production and Testing Engineer at Watt4Ever, presented his work on the benchmark depository of 2nd life use of lithium in batteries, acceptance criteria and guidelines, work developed within the RHINOCEROS project. Benjamin Wilson, representing the RESPECT Project, displayed Aalto University’s work advancing efficient, sustainable, innovative and safe battery recycling processes in the EU. Laura Kainiemi from LUT University, representing the RELiEF Project, Konstantinos Komnitsas from the Technical University of Crete (TUC), on behalf of EXCEED, and Vitor Correia from INTRAW for the CRM-geothermal project, collectively debated the role and impact of social acceptance among affected communities, the importance of triggering new dialogues on responsible mining activities, and the joint involvement of regional, national and European authorities, academia, industry partners, and citizens in shaping these initiatives.
A big thank you to all participants for this co-creative and very constructive and inspiring meeting.

Starting with work package (WP) 2, partners from EnBW presented the characteristics of the Bruchsal geothermal reservoir, located at the eastern edge of Upper Rhine Valley. EnBW highlighted that geothermal brines in the Upper Rhine Valley are recognised for their relatively high lithium (Li) concentrations. Additionally, the region displays an extension structure striking in the NNE-SSW direction, with a length of around 300 km and a width of up to 40 km. In this area, the deep geothermal fluids utilised for geothermal applications exhibit a maximum Li concentration ranging from 163 to 190 mg/L (Sanjuan et al., 2016). The highest Li concentration was detected in the hydrothermal alteration zone of Lower Buntsandstein.
In the forthcoming months, new samples are prepared for delivery to research partners: geothermal and continental brines, but also Li-phosphate samples, a new Li-mica concentrate and synthetic brine solutions. Upcoming research will mainly focus on the geochemical analysis of rock samples from the reservoirs.
In the mining industry or extractive metallurgy, beneficiation is any process which removes the gangue minerals from ore to produce a higher-grade product, and a waste stream – which, despite the lack of valuable materials, needs to be sustainably treated. In charge of the beneficiation step, TU Delft already presented in M12 videos of the operational opto-magnetically-induced sorting lab setup to process crushed spodumene ore. This proof of concept aims to separate the Li-rich fractions of the ore before reaching the metallurgical processes. This preliminary step helps improve efficiencies and decrease cost in processes downstream.
Researchers at NTUA, working on the development of a calcination technology working at lower temperatures, presented the first results of their investigations using various additive combinations and leaching experiments studying the effect of temperature, time and leaching agents. Tests showed that the use of additives has the potential to maintain the calcination operating temperature of spodumene at low temperatures compared to conventional routes. Moreover, researchers achieved over 92 % Li extraction during various leaching experiments conducted so far. Recognising the environmental footprint associated with the conventional routes used for Li extraction, NTUA research team will continue experimenting with new additives in order to develop a new technology that is more environmentally sustainable and equally more competitive.
Working with spodumene samples, TECNALIA researchers have been working on the ball milling-assisted chemical transformation, testing the use of various additives and experimenting with different thermal treatments. Their upcoming work will focus on optimising the ball milling process to obtain materials with similar leaching properties but being produced with less intense thermal processes.

Late September 2023, ministers, industry leaders, investors, international organisations and civil society convened at IEA (International Energy Agency) headquarters for first-of-its-kind summit to discuss the future of critical minerals.
Being the first international IEA Critical Minerals and Clean Energy Summit, the event applauded governments’ enthusiasm to deploy the clean energy transition, as well as their quick actions to ensure secure and sustainable supplies of critical minerals. With a concerning scenario portraying surging demand of minerals such as lithium, cobalt, nickel and copper, driven by the deployment of clean energy technologies, the first international summit identified six key actions to ensure secure, sustainable and reliable supplies of critical materials:
The majority of these strategic actions are already included in the core of the LiCORNE project. Launched in October 2022, LiCORNE is designed to establish the first European Lithium complete supply chain. Its main objective is to increase the processing and the refining capacity for battery-grade chemicals from resources available in Europe: ores, brines, tailings and off-specification battery cathode materials (waste).
With increased interest for this first international summit, the IEA will hold a Ministerial Meeting next year, in February, which will provide countries with a platform to evaluate the significance of critical minerals in the global energy security and climate action. Based on shared experiences and information, the event will emphasise transparent and resilient supply chain strategies, and unveil the next phase of the IEA Voluntary Critical Mineral Security Programme.

Between 14 and 18 November 2022, the European Commission organised the 7th edition of the Raw Materials Week gathering a wide range of stakeholders discussing policies but also relevant alternatives in the field of raw materials. This was an opportune occasion for the LiCORNE project to cluster with seven other EU-funded projects at the event “Production of raw materials for batteries from European sources”. The objective of the workshop was to create an environment that could foster knowledge exchange on different approaches for the recycling and recovery for battery applications. Co-organised by CROCODILE, RHINOCEROS and LICORNE, with the participation of the EU funded projects BATRAW, RESPECT, RELiEF, FREE4LIB and ENICON, the workshop gathered nearly 100 organisations driving the production and the recycling of raw materials for battery applications from primary and secondary resources.
Due to the increasing usage of batteries for electric vehicles (EVs) and energy storage systems generated by the EU’s mission to limit climate change, the demand for many metals relevant for batteries is expected to grow by more than 1000% by 2050. Held in a hybrid format, the workshop provided participants with the opportunity to discover innovation routes followed by the clustering projects on their pathway to secure sustainable and responsible sourcing of raw materials for battery production.
Nearly three hours packed with presentations provided stakeholders with essential information about each project, from the main objectives and expected outcomes, to the lessons drawn from the activities carried out.
The CROCODILE project – First of a kind commercial Compact system for the efficient Recovery of Cobalt Designed with novel Integrated Leading technologies– was presented by Dr. Lourdes Yurramendi (TECNALIA). As the most mature project, CROCODILE’s keynote focused on valuable findings and learnings regarding different aspects of the project: the samples treatment, the selection of flowsheets, the life cycle analysis (LCA) and cost (LCC) of the pilot unit, to name only a few. Later on Monday, the project was also featured as a Success Story in the Raw Materials Week, where the presentation video was played for the first time.

Sonia Matencio Lloberas (LEITAT) presented the BATRAW project – Recycling of end-of-life battery packs for domestic raw material supply chains and enhanced circular economy. This project will develop and demonstrate two innovative pilot systems for sustainable recycling and end-of-life (EoL) management of EV batteries. Depending on the results obtained, these technologies could be extended to other types of batteries to recover all the metals and materials contained: i.e., cobalt, nickel, manganese, lithium, graphite, aluminium, and copper.

Nader Akil (PNO Innovation Belgium) explained the mission and the motivation behind the RHINOCEROS project – Batteries reuse and direct production of high performances cathodic and anodic materials and other raw materials from batteries recycling using low cost and environmentally friendly technologies. As attractive energy storage technologies, Lithium-ion batteries (LIBs) have proven to be a reliable solution, especially when it comes to the production of low-emission fleets (EVs), followed by stationary storage market and consumer electronics. According to the Strategic research Agenda for Batteries, by 2030, the global demand for LIBs is estimated to increase 14 times and the EU could account for 17%. The battery market is expected to reach 250 billion EUR/year by 2025, while the production in Europe is foreseen to rise to 300 GWh/year as of 2030. This generates opportunities for projects like RHINOCEROS to develop economically and environmentally viable routes for re-using and recycling EoL EVs and stationary energy storage Lithium-ion batteries (LIBs).

Similar to the RHINOCEROS project, FREE4LIB [Feasible recovery of critical raw materials through a new circular ecosystem for a Li-ion battery cross-value chain in Europe] aims to simplify the recycling process of LIBs, as a more resilient and environmentally friendly alternative to the current linear economic model – take, make, dispose. The project, presented by Juan Castro (CARTIF), will develop six technologies at TRL5 to achieve new sustainable and efficient processes to recycle EoL LIBs: dismantling, pre-treatment and four materials recovery processes aiming to reach highly efficient materials recovery (metal oxides, metals and polymers). Additional to the recycling solutions, FREE4LIB will also target three processes dealing with metals and polymers re-using and electrode synthesis to re-manufacture new LIBs.

Justo Garcia (Orano Mining) presented the RESPECT project. Funded by the Horizon Europe research and innovation programme, the project aims to strengthen expertise in techniques and the value chain for the recycling of electric vehicle batteries at European level. The RESPECT project will develop a global process encompassing a process-chain flexible enough to treat all kinds of batteries in closed loop. Precisely, researchers will explore two recycling routes: full hydrometallurgy and direct recycling, and an improved Life Cycle Assessment of each recycling segment to reduce emissions, health risks and safety issues.

Gabriel Hidalgo, from the Recycling Unit of Avesta Battery & Energy Engineering (ABEE), outlined the objectives and the impact expected from the RELiEF project – Recycling of Lithium from Secondary Raw Materials and Further. Expected to boost the recycling industry, this project aims to reduce Li waste by more than 70%, and to transform recycled resources into high value battery-grade material. Relying on a very diversified consortium, RELiEF will additionally propose a new business model for materials acquisition and processing, taking into consideration environmental and social sustainability.

Sofía Riaño Torres (KU LEUVEN) presented the last EU project, ENICON– Sustainable processing of Europe’s low-grade sulphidic and lateritic nickel/cobalt ores and tailings into battery-grade metals -Launched in June 2022, the project aims to improve the refining capacity of domestic and imported low-grade Ni/Co. ENICON’s metal recovery route using hydrochloric acid dispenses with the old-school hydro-based approach that involves continuously precipitating and redissolving metals. Thus, it reduces the amount of chemicals needed for metal dissolution, which results in the production of potentially harmful waste streams. More information about the project in the joint documentary commissioned together with EU funded project NEMO: Responsible Mining in Europe.

Although only in its first edition, the clustering workshop Production of raw materials for batteries from European resources attracted a diversified range of stakeholders. Counting more than 150 people registered, the audience was dominated by research organisations (26,97%), the rest of the audience being equally distributed between academia (17,76%), large companies (17,11%), SMEs (16,45%), EU institutions (4,61%) and other stakeholders addressing raw materials – national and regional administrative authorities, logistics service provides, investing companies, trade associations, NGOs, consulting companies (17,76%). Participants are located mainly in Europe but a percentage of nearly 20% shows growing enthusiasm from third countries, such as Turkey, Canada, South Korea, Chile, etc.
With the real peak of valuable outcomes from H2020 projects coming now, the aim goes beyond informing about the progress achieved to date. Building on the knowledge generated so far, new projects need to address different challenges, such as the high cost of exploration activities, the geological uncertainty, and the necessity to develop improved processing and refining technologies for better recovery of minerals and metals from side streams and industrial waste. Such challenges require close collaboration on all levels and across the entire battery value chain.
The last part of the event featured an interactive session, which included seven questions scrutinising stakeholders’ interest for similar clustering initiatives. With favourable answers and reviews, the Production of raw materials for batteries from European resources could turn into a permanent clustering hub fostering knowledge exchange and stimulating synergies between projects. More information will follow soon.
