Semantic Schism: Steel Standards Still Split Significantly

As of mid‑2025, no unified definition for “green steel” exists in Europe. Fernando Pessanha Santos of Hydnum explained: “There is no definition so far… sustainability as a whole… reuse residual ‘gray’ water… zero emissions for the steel we produce,” stressing the industry’s focus is evolving beyond CO₂ thresholds. Major brands, XCarb, Arvzero, SSAB Zero, Bluemint, Greentec, all use different standards , complicating comparability and fostering confusion among buyers and regulators.

Ambiguity Amplified: Premiums Priced, But Purchase Patience Paltry

Green flat steel attracts premiums of €170–200 ($190–225)/tonne in Northern Europe, while green long steel premiums hover around €20–30 ($22–33)/tonne. Despite this, buyers remain cautious. Carvalho noted fragmented definitions across sectors, stating standardisation around a carbon footprint threshold is vital for scaling adoption.

Feedstock Furore: DR‑Grade Ore & Scrap Supply Squeezed

Fastmarkets estimates 40–50 million metric tons of green steel capacity will come online by 2030. But feedstock availability poses a bottleneck, DR‑grade pellets and high‑quality scrap are limited. José Noldin shared that GravitHy has secured 50 % of its feed supply from Rio Tinto, yet future shortages loom. Pessanha pointed out scarcity breeds opportunity: “If there is a scarcity, there is a premium,” he said. Energy access also remains crucial, green steel production demands cheap, reliable, renewable electricity.

Economic Equations: Green Hydrogen & Market Mechanisms

Green H₂ remains largely aspirational, current supply is small-scale and costly. Alternative mass‑balance models without rigorous emissions oversight raise credibility issues. Noldin asserted: “Green steel is… produced with minimized CO₂ content… less than X kg of CO₂ per 1 tonne,” advocating for emissions-based definitions .

Demand Dissonance: End‑User Apathy & Policy Paralysis

End-users have yet to fully embrace green steel premiums. Service centres, where steel costs dominate, resist added expense. Automotive buyers, particularly in luxury and premium segments, exhibit greater readiness. Noldin warned that without unified definitions, procurement remains stalled. “Some customers are a bit lost… definition, again, we need to converge,” he said . Green steel thus remains niche without public-sector lead demand.

Flat Vs Long: Quality Quiplash in Premiums

Long steel produced via EAF fetches modest premiums (€20–30 / $22–33 per tonne), while flat steel sees significantly larger premiums (€170–200 / $190–225 per tonne). Fastmarkets defines green flat steel as ≤ 0.8 metric tons CO₂ per tonne, and green long steel as ≤ 0.5 metric tons CO₂ per tonne. Differentiated standards drive disparity in pricing structures.

Regulatory Reckoning: CBAM’s Crucial Catalytic Potential

The EU’s Carbon Border Adjustment Mechanism, launching January 2026, is expected to transform market dynamics. Pessanha described it as “a very, very important driver… changes the market dynamics”. However, he cautioned that without public procurement mandates for green steel, CBAM alone may not prompt large-scale uptake .

Strategic Signposts: Scarcity Spurs Scale, Policy Paves Path

Despite uncertainties, panelists were optimistic. Noldin called decarbonisation a “fantastic opportunity,” affirming Europe’s green steel future . Fastmarkets sees 46 million metric tons of hydrogen-based green steel by 2035, though initial roll-out may be uneven. The emerging consensus: clarifying standards, securing feedstock, lowering energy costs, and enacting CBAM and procurement policies are essential enablers.

Key Takeaways:

• Europe still lacks a unified “green steel” definition; industry leaders call for CO₂ thresholds & transparent methodologies, also water and scrap use metrics matter.

• Green steel premiums diverge: flat steel commands €170–200 ($190–225)/tonne, whereas long steel attracts only €20–30 ($22–33)/tonne.

• Feedstock shortages and policy gaps threaten projected 40–50 million metric tons of green capacity by 2030; CBAM and public procurement are key to unlocking scale.
