The Italian Ministry of Environment and Energy Security (MASE) recently convened a conference and strategic workshop in Rome to address the burgeoning market for lithium extraction from geothermal brine.
The event, titled “Extraction of lithium from geothermal brine: potential and future challenges,” brought together representatives from various sectors, including companies like ENEL Green Power, Steam, Turboden, and IREN/Altamin, as well as research institutions such as the National Research Council (CNR) and RSE.
Exploring the Integrated Supply Chain and Policy Landscape
The workshop delved into the complexities of establishing an integrated supply chain for low-carbon lithium production in conjunction with geothermal energy.
Discussions ranged from policy-making at different governmental levels to scientific research and the challenges faced by both public and private sectors. This initiative underscores Italy’s commitment to developing local solutions that contribute to a carbon-neutral future.
MASE’s Dedication to Ongoing Dialogue and Resource Assessment
Director Barbaro of MASE expressed the ministry’s dedication to fostering continued discussions on geothermal resources and their potential. He acknowledged the need for further exploration of other raw materials beyond lithium, highlighting the importance of assessing Italy’s untapped resources.
The conference’s initial phase centered on the legal aspects of the geothermal sector, with a particular focus on the European Regulation on Critical Raw Materials, which came into effect in May 2024, and the recently introduced Critical Raw Materials Legislative Decree.
These legislative measures aim to align Italy’s mining sector regulations with European objectives and standards, promoting both digital and green transitions.
Stakeholder Recommendations and Hopes for Regulatory Innovation
Both the National Council of Geologists and the Italian Geothermal Union shared their recommendations and aspirations for regulatory advancements that would benefit the geothermal sector. They emphasized the importance of a supportive legal framework to facilitate sustainable geothermal development.
Technical Presentations on Lithium Extraction Technologies
The latter part of the workshop featured technical presentations by companies actively involved in lithium extraction or engaged in research and development initiatives. Participants showcased both established and emerging technologies with the potential to enhance environmental performance and energy efficiency in lithium production.
Leading Italian research institutions are also actively investigating methods to harness geothermal resources for both energy generation and domestic lithium production.
Lithium’s Significance in the Circular Economy and Beyond
The extraction of lithium from geothermal brines presents an opportunity to maximize the utilization of geothermal resources.
This extracted lithium can be used in various applications, notably in the production of batteries for the automotive industry. The development of lithium production from geothermal brines, utilizing circular economy principles, represents a significant step towards a more sustainable and resource-efficient future.
