Pan-European Paradigm & Paris-Pact Priorities: The Green Steel Imperative

The European Commission has intensified its decarbonisation drive by unveiling a major funding initiative under Horizon Europe, targeting one of the bloc’s most emission-intensive sectors: iron & steel. With $28 million in available grants, the Clean Steel Partnership is seeking ambitious proposals to tackle systemic technological barriers in transitioning to low-carbon and eventually carbon-neutral steel production. The initiative is part of Europe’s long-term strategy to meet the goals of the Paris Agreement, phase out free carbon allowances under the EU ETS, and establish global leadership in clean industrial innovation.

Smelter Scenarios & Steel Sustainability: Scope of The Proposal Call

The call for proposals is open until September 23, 2025, and encourages multi-disciplinary collaboration among academic institutions, research bodies, small & medium enterprises, and large industrial players. Projects must aim to validate and solve essential challenges impeding the widespread adoption of innovative steelmaking technologies. The ultimate objective is to ensure these technologies reach commercial maturity and industrial-scale reliability. The call supports research, innovation, coordination, and co-funding actions that will underpin a scalable, circular, and climate-resilient metallurgical economy.

Reductant Reconfigurations & Raw Material Realities: Dealing with Material Diversity

A key focus of the call is the increasing heterogeneity of input materials used in steelmaking. Applicants are required to devise methods for adapting processes to cope with varying grades of raw materials and reductants, be they gaseous (like H₂), solid (coal, biochar), or liquid. The technical challenge lies in creating a process robust enough to handle impurities and inconsistencies without compromising product quality. Applicants must also evaluate the sustainability and carbon footprint of producing these alternative reductants, addressing not only emissions but energy and resource use.

Microscopic Mechanisms & Metallurgical Modelling: from Contaminants to Crystalline Control

To enable high-quality output from lower-grade inputs, the call asks for projects that adapt microstructures of steel, improving tolerance to contaminants. This includes adjusting production parameters and applying advanced control technologies to modify metallurgical properties in real time. Proposals should also develop detection and measurement systems to monitor contaminants, alongside multi-scale computational models to simulate the structural, thermal, and chemical behavior of materials during processing. Such innovations will help tailor steel properties for different industrial applications while maximizing resource efficiency.

Furnace Flexibility & Facility Futures: Innovating at Plant Level

The Commission urges applicants to look beyond the laboratory and envision next-generation plant designs. Projects should include engineering and operational adaptations necessary for integrating new technologies such as direct reduced iron methods using hydrogen, plasma-based refining, or carbon capture-ready furnaces. This extends to evaluating plant-wide process stability, safety protocols, and flexibility in switching between feedstock types. Plant-level reconfiguration must also account for risk mitigation during production, particularly when combining primary and secondary raw materials.

Residue Reinvention & Resource Recirculation: Toward a Circular Steel Economy

Waste valorisation is another cornerstone of the call. Projects must propose ways to reduce, reuse, or recycle production residues, including slag, dust, and sludge. This entails characterising the environmental and economic impacts of residues under new low-CO₂ production scenarios. For instance, how does the use of mixed secondary scrap affect the residual characteristics of the output? Can these residues be transformed into construction materials or chemical inputs? Applicants are expected to analyse material and energy balances, develop residue management strategies, and explore opportunities for byproduct valorisation.

Academic Alchemy & Applied Alliances: The Commission’s Co-Creation Mandate

This call strongly advocates for the “co-creation” model between academia and industry, in accordance with Commission Recommendation 2024/774. The goal is to ensure research knowledge is valorised, translated into tangible commercial applications. Proposals must demonstrate meaningful collaboration, where knowledge flows bi-directionally. Academic institutions provide theoretical insight and experimental frameworks, while industry partners offer real-world testing, scalability input, and potential for deployment in commercial steel mills. The partnership model is crucial for reducing innovation lag and speeding up the transition from concept to implementation.

Eligibility Epitome & Evaluation Essentials: Who Qualifies & What’s Expected

The call is open to any legal entity established in an EU Member State, Horizon Europe-associated country (e.g. UK, Norway, Israel), or select overseas territories. All proposals must address at least four of the eight outlined challenges in the call scope. Proposals will be evaluated based on scientific excellence, societal impact, and implementation feasibility. Successful applicants will receive funding to conduct pilot tests, simulations, and techno-economic assessments over multi-year project timelines. The final expectation is to deliver validated low-carbon iron & steelmaking technologies ready for commercial investment by 2030.
