The STORECO₂ team is currently carrying out a gas flux and sampling campaign at the Castiglioncello magnesite deposit (Tuscany, Italy)
This video shows how gas samples are collected in the field, and in particular this site represents a unique natural analogue where serpentinite rocks naturally react with CO₂-rich fluids, forming stable carbonate minerals.
Our objective is to better understand the geochemical processes involved in natural CO₂ mineralisation and use this knowledge to develop scalable strategies for safe, permanent carbon storage.
The data collected during this campaign will support the construction of a conceptual model to evaluate the efficiency and long-term potential of mineral carbonation in ultramafic rocks.
Stay tuned for updates as we work toward innovative solutions for climate mitigation through carbon capture and storage (CCS).
We are pleased to announce that the STORECO₂ project featured at the Third IAGC International Conference Water–Rock Interaction (WRI‑18) and Applied Isotope Geochemistry (AIG‑15) held in Cagliari this June.
Results from the STORECO2 project were presented in a keynote talk in the session “Carbon Capture and Storage and hydrogen for Energy Transition”.
Below are a few slides from the presentation, which focused on what it would take to reproduce the efficiency of serpentinite carbonation observed in natural systems such as magnesite deposits.
We are proud to share that results from the STORECO2 project were presented at the conference “Critical Raw Materials for Energy”, organised by the Accademia Nazionale dei Lincei as part of the series “The Future of Humanity”.
Our contribution was: “Magnesite: a solution for CRM and mineral-based CCS” focusing on the double benefit of understanding the formation of magnesite deposits, being a source of CRM (Mg) and an analogue for carbon storage through mineral carbonation.
The event brought together leading figures from academia, institutions, and industry to address the scientific, economic, and geopolitical challenges related to the supply, recycling, and substitution of critical raw materials.
We are pleased to announce the successful completion of the second geoelectric survey by the OGS team at the Castiglioncello magnesite mine in Tuscany (Italy), a key step in our ongoing efforts to understand the dynamics of natural mineral carbonation for long-term CO₂ storage.
This new survey focused on a targeted transect across the mineralisation, building on previous work to deliver high-resolution imaging of the subsurface. The data will enable us to refine our understanding of the continuity and depth extent of the magnesite body and associated alteration zones.
This step is essential for enhancing our geophysical model of the deposit, supporting both scientific interpretation and potential future evaluation of the site as a natural analogue for carbon storage.
Stay tuned for further updates as we integrate these results with geochemical and mineralogical data from the 2025 field campaign!
We’re excited to have shared the initial findings from the STORECO2 project at the AGU 2024 Fall Meeting in Washington!
Our contribution to the session “Advances in CO2 Capture, Transport, Utilisation and Storage” focused on the early insights we’ve gained into natural CO2 sequestration through serpentinite carbonation looking at natural analogues in the Ligurian Ophiolite of Tuscany.
It has been a great time for discussion and exchanging new ideas with the scientific community. We look forward to building on these early findings and contributing to the ongoing efforts to combat climate change!
The CCS Lab aims to be a key player in advancing technologies to reduce CO₂ emissions. Established within the Institute of Geosciences and Georesources, the lab focuses on developing and applying Carbon Capture and Storage (CCS) and Mineral Carbon Capture and Storage (CCMS), technologies essential for a sustainable energy transition.
Carbon Capture and Storage (CCS): A Solution for the Future
CCS is a cutting-edge technology designed to capture CO₂ from hard-to-abate industrial sectors and store it in deep geological formations. This process prevents CO₂ from entering the atmosphere, making a significant contribution to combating climate change and achieving carbon neutrality goals.
CCMS: The Innovative Alternative
CCMS builds upon CCS by utilizing mafic and ultramafic rocks (e.g., basalts, peridotites, serpentinites) that chemically react with CO₂. Through mineral carbonation, CO₂ is converted into stable carbonates (e.g., magnesite, calcite) and stored permanently over geological timescales.
This approach also involves using industrial by-products rich in calcium and magnesium, such as steelmaking and cement residues, providing a sustainable solution for recycling waste materials and reducing emissions. CCMS not only paves the way for a low-carbon future but also fosters a circular economy and helps achieve “end of waste” goals for industrial residues.
The Role of the CCS Lab
The CCS Lab conducts research on CCS and CCMS technologies across diverse geological contexts, with a particular focus on the Mediterranean region. Combining multidisciplinary expertise, state-of-the-art instrumentation, and advanced methods like machine learning and geological modeling, the lab tackles complex challenges such as:
Investigating natural carbonation processes in mafic and ultramafic rocks
Identifying optimal conditions for mineral carbonation
Assessing the effectiveness of CCMS technologies
Mapping suitable CO₂ storage sites in Italy
Conducting feasibility studies and monitoring for CCS and CCMS facilities
Developing scalable, sustainable solutions for large-scale implementation
The CCS Lab’s multidisciplinary approach bridges cutting-edge research with practical applications, driving innovation and supporting a sustainable energy transition.
Contributing to Environmental Sustainability
Through constant research and innovation, the CCS Lab leads the way in carbon storage technologies, offering tangible solutions to global climate challenges. By combining pioneering science with practical applications, the lab accelerates decarbonization efforts.

We are excited to announce the start of our soil sampling campaign at the Castiglioncello magnesite mine, a crucial part of the STORECO2 project.
In the coming weeks, our team will collect soil samples from various locations around the mine to analyse mineral composition and geochemical properties. These samples will help us better understand the natural processes that led to magnesite formation and how the environment responds to this process. The Castiglioncello mine (Livorno, Italy) will serve as a key natural analogue for assessing potential environmental impact of large-scale carbon storage through mineral carbonation .
We are excited to announce our recent contribution at the European Mineralogical Society (EMC) conference. Our research team presented an abstract titled “Metal mobility during serpentinite carbonation: evaluating recovery potential and environmental impact” showcasing our latest findings in the field of mineral carbonation and critical raw materials.
This conference provided an invaluable platform to share our advancements with fellow researchers and experts, facilitating discussions on innovative methodologies and emerging trends in mineralogical research. Our presentation highlighted the mobility of potentially hazardous metals during mineral carbonation, contributing to the ongoing effort on the understanding how to upscale safely mineral carbonation techniques. Below you can see a compositional map of carbonated serpentinite, highlighting the distribution of chromium, iron and nickel. The small insert instead shows different XANES patterns for Cr species.

We are excited to announce the successful completion of a seismic survey conducted as part of the STORECO2 project. This survey was carried out by the National Institute of Oceanography and Applied Geophysics (OGS) and represents a significant milestone in our efforts to characterise the subsurface structures of the study area.
The seismic survey will provide detailed insights into the geological formations, helping us to map subsurface features critical for understanding the potential for CO2 storage and the processes of mineral carbonation. These findings are crucial for assessing the suitability of the site for secure and efficient CO2 sequestration.
This achievement marks an important step forward in the project, and we look forward to sharing more developments soon. Stay tuned for further updates on our progress!
