M-ERA.NET 3 aims at coordinating the research efforts in the participating EU Member States, Regions, and Associated States in materials research and innovation, including materials for future batteries, to support the circular economy and Sustainable Development Goals. A large network of national and regional funding organisations from 25 EU Members States, 4 Associated States and 6 countries outside Europe will implement a series of annual joint calls to fund excellent innovative transnational RTD cooperation, including one call for proposals with EU co-funding and additional non-cofunded calls. Continuing the activities started under the predecessor project M-ERA.NET 2 (3/2016-2/2021), the M-ERA.NET 3 consortium will address emerging technologies and related applications areas, such as - for example- surfaces, coatings, composites, additive manufacturing or integrated materials modelling. Research on materials supporting the large scale research initiative on future battery technologies will be particularly highlighted as a main target of the cofunded call (Call 2021) with a view to supporting in particular SDG 7 (“Affordable and clean energy”) by enabling electro mobility through sustainable energy storage technology and SDG 9 (“Industrial innovation and infrastructure”) by enhancing scientific research and upgrading the technological capabilities of industrial sectors. Several relevant action plans and initiatives will serve as programmatic guides for M-ERA.NET 3 when defining the joint activities, such as the Circular Economy Action Plan, the 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals, the EC communication “A clean planet for all”, and the “European Green Deal”. The total mobilised public call budget is expected to reach 150 million € with additional private investment of 50 million €. Thus, the leverage effect of the EU contribution will reach a factor of 13, exceeding by far the minimum required factor of 5.
