The MECALO project, funded by Horizon Europe, is at the forefront of revolutionizing the production of critical raw materials (CRMs) in Europe. By focusing on Silicon and Manganese, essential components for clean technology initiatives, MECALO aims to achieve CO2-neutral production by leveraging renewable hydrogen and innovative carbon-looping technologies. This initiative aligns with the EU's Critical Raw Materials Act to ensure a secure and sustainable supply of CRMs while advancing climate neutrality goals. MECALO addresses Europe's heavy dependence on imports for critical raw materials, highlighting the need to enhance domestic production for industrial resilience. Through advancements in renewable hydrogen integration and carbon looping technology, the project aims to replace coal imports with hydrogen, significantly cutting CO2 emissions in metallurgical processes. The project overcomes challenges in decarbonizing industries that rely on carbothermic reduction by introducing innovative approaches that could set a standard for sustainable CRM production. With a diverse consortium of partners, including research centers, SMEs, and industrial partners from across the EU, MECALO ensures a comprehensive approach to achieving its ambitious goals. The project's kickoff in Trondheim, Norway, marked the beginning of a 42-month initiative aimed at transforming CRM production sustainably. By prioritizing CO2-free production and collaborative research, MECALO seeks to secure Europe's position in the global market while enhancing industrial autonomy. This venture not only reduces environmental impact but also aligns with Europe's climate neutrality targets, paving the way for a cleaner and more sustainable future for critical raw material production.
