Decarbonisation's Dawning Dilemma & Direct Reduction's Defining Role The global steel industry's journey toward carbon neutrality is accelerating in ambition yet decelerating in execution, a paradox that Dr. John Atherton, secretary general of the International Iron Metallics Association, placed in sharp analytical relief during his address at the second session of the Spring 2026 Conference & 94th International Rebar Exporters & Producers Association Meeting in Amsterdam on April 26-28, 2026. Speaking to an audience of steel producers, traders, & raw material suppliers gathered at one of the sector's most consequential annual forums, Dr. Atherton outlined the evolving role of iron metallics in the transition toward carbon-neutral steelmaking, mapping both the structural opportunities & the growing challenges that now define the sector's decarbonisation trajectory. At the heart of his analysis was the rising prominence of direct reduced iron as a key enabler of low-carbon steel production, a technology pathway that has gained substantial traction in industry planning documents, policy frameworks, & investment announcements over the past five years. Direct reduced iron, produced by reducing iron ore using a reductant gas rather than the coking coal employed in conventional blast furnace operations, generates substantially lower CO₂ emissions per metric ton of steel produced, particularly when the reductant gas is natural gas rather than coal-derived syngas. When the reductant is green hydrogen, produced via electrolysis powered by renewable electricity, the process can theoretically achieve near-zero CO₂ emissions, making hydrogen-based direct reduced iron the most widely cited pathway to achieving the deep decarbonisation targets of 80-90% that climate scientists & policymakers have established for the steel sector. The global green steel market, valued at $8.46 billion in 2025, is projected to grow at a compound annual growth rate of 55.6%, potentially reaching $186.82 billion by 2032, a trajectory that underscores the scale of commercial interest in the transition even as execution challenges mount. Dr. Atherton's address provided a sober counterpoint to this optimistic market narrative, grounding the discussion in the operational realities that are slowing the transition from announced ambition to commissioned capacity.

Hydrogen's Hesitant Horizon & the Hegemony of Natural Gas Central to Dr. Atherton's analysis was a frank assessment of the current state of hydrogen availability & cost, the two variables that most directly determine whether hydrogen-based direct reduced iron production can transition from a demonstration-scale technology to a commercially viable, globally deployed industrial process within the timeframes that climate commitments demand. His assessment was unambiguous: hydrogen availability & cost remain the primary barriers to widespread adoption of hydrogen-based direct reduced iron, & the timeline for resolving these barriers is substantially longer than the optimistic projections that characterised industry discourse in the early 2020s. Natural gas-based direct reduced iron production is expected to remain dominant until hydrogen becomes cost competitive, a qualification that carries enormous practical significance given that the cost of green hydrogen, produced via renewable-powered electrolysis, currently ranges from $4 to $8 per kilogram in most markets, compared to a viability threshold for steelmaking applications widely estimated at $1 to $2 per kilogram. This cost gap, while narrowing as electrolyser technology matures & renewable electricity prices decline, is not expected to close sufficiently to make green hydrogen competitive at scale before the late 2020s at the earliest in the most favourable locations, & considerably later in regions where renewable energy resources are less abundant or grid infrastructure less developed. Dr. Atherton noted that naturally occurring hydrogen resources could play an important role in the future, a reference to geological hydrogen deposits that have attracted growing scientific & commercial interest, but acknowledged that their development remains at an early stage, offering no near-term relief to the cost & availability constraints facing the industry. The International Energy Agency has estimated that achieving the steel sector's net-zero trajectory requires green hydrogen costs to fall to approximately $1 per kilogram by 2050, a target that is technically achievable but requires sustained policy support, infrastructure investment, & electrolyser manufacturing scale-up that is currently proceeding more slowly than optimistic scenarios projected.

Capital's Crushing Calculus & the Trillion-Dollar Transformation The financial dimensions of the green steel transition are staggering in their scale, & Dr. Atherton's address at the Amsterdam conference placed a specific & sobering figure at the centre of the investment discussion: the transition to hydrogen-based production routes in Europe alone could require capital expenditure of up to $1.5 trillion, a sum that dwarfs the annual capital budgets of even the largest global steelmakers & underscores the fundamental impossibility of achieving the transition through private investment alone. This $1.5 trillion estimate encompasses the full stack of infrastructure required for hydrogen-based steelmaking at European scale, including electrolyser capacity, renewable electricity generation, hydrogen storage & distribution networks, direct reduced iron plant construction, electric arc furnace installation, & the associated grid upgrades & port infrastructure necessary to handle new raw material flows. The magnitude of this investment requirement has direct implications for the pace of the transition, as individual steelmakers, even those of the scale of ArcelorMittal or thyssenkrupp, cannot absorb capital commitments of this order without either compromising their balance sheet stability or securing substantial public co-financing through mechanisms such as the European Union's Innovation Fund, the Important Projects of Common European Interest framework, or national state aid schemes. Dr. Atherton emphasised that policy support mechanisms such as carbon pricing are critical to bridging the gap between the cost of green hydrogen-based production & the market price of conventionally produced steel, a gap that currently ranges from €150 ($165 USD) to €300 ($330 USD) per metric ton depending on product category, production route, & regional energy cost profile. The green steel market's projected growth from $8.46 billion in 2025 to $186.82 billion by 2032 implies a compound annual growth rate of 55.6%, a figure that reflects the scale of commercial ambition but also the enormous base-effect advantage of starting from a very low absolute production volume. In practice, green steel currently accounts for less than 1% of global steel production, meaning that even rapid percentage growth in green steel output will leave the vast majority of global steel production carbon-intensive for the foreseeable future.

Scrap's Sinuous Sufficiency & the Sine Qua Non of Iron Metallics One of the most technically nuanced dimensions of Dr. Atherton's address concerned the relationship between scrap availability, direct reduced iron supply, & the long-term feedstock economics of electric arc furnace-based steelmaking, a relationship that is frequently oversimplified in public discourse about the green steel transition. The conventional narrative of green steel transition posits a straightforward substitution: blast furnace-basic oxygen furnace production routes are replaced by electric arc furnaces fed primarily by recycled steel scrap, supplemented by direct reduced iron where scrap quality or availability is insufficient. Dr. Atherton challenged the adequacy of this narrative, warning that the shift toward direct reduced iron & electric arc furnace-based production could create new challenges regarding scrap availability & quality that are not fully accounted for in transition planning. He stated that while scrap will continue to play a crucial role in the circular economy, impurities & limited supply mean that direct reduced iron will remain an essential input even in scrap-rich regions, a conclusion that has significant implications for the investment case for direct reduced iron production capacity globally. Steel scrap contains a range of residual elements, including copper, tin, & nickel, that accumulate through successive recycling cycles & cannot be economically removed using conventional electric arc furnace metallurgy. As the proportion of recycled steel in the global steel supply increases, the average impurity burden of available scrap rises, creating quality constraints that limit its suitability for the production of high-specification flat steel products used in automotive, electrical, & packaging applications. Direct reduced iron, produced from high-grade iron ore, provides a dilution effect that reduces the impurity concentration in the electric arc furnace charge, enabling the production of higher-quality steel from a mixed scrap-direct reduced iron feedstock. The International Iron Metallics Association forecasts that demand for merchant direct reduction-grade pellets will surge significantly over the coming decade, driven precisely by this quality imperative, creating substantial commercial opportunities for iron ore producers capable of supplying the high-grade, low-gangue ore required for direct reduction applications.

Project Postponements & the Perturbation of Promised Capacity The gap between announced green steel project capacity & the volume of capacity currently under active construction is one of the most revealing indicators of the structural challenges facing the transition, & Dr. Atherton's data on this gap was striking in its implications. He noted that although global direct reduced iron capacity is projected to increase significantly over the coming decade, less than half of the announced capacity is currently under construction, reflecting the uncertainties surrounding investment decisions & policy support that are causing developers to defer final investment decisions or, in some cases, cancel projects entirely. This announcement-to-construction conversion rate of less than 50% is a significant deterioration from the optimism that characterised the sector in 2021-2023, when a wave of green steel project announcements, many of them conditional on policy support or technology partnerships, suggested that the transition was accelerating rapidly. The subsequent period has seen a number of high-profile project delays & cancellations, including the suspension of ArcelorMittal's green direct reduced iron production plans at its German operations, the deferral of several hydrogen-based steelmaking projects in Sweden & Finland, & the scaling back of ambitious timelines at projects in the United States, Canada, & Australia. Dr. Atherton's observation that progress on steel decarbonisation has so far fallen short of earlier expectations is consistent the findings of the Institute for Energy Economics & Financial Analysis, which noted in its 2026 analysis that "after a couple of years of slower progress, the steel technology transition away from fossil fuels could gain renewed momentum in 2026," a cautiously optimistic framing that nonetheless acknowledges the setbacks of the preceding period. The factors driving project delays are multiple & interconnected: energy cost uncertainty, policy instability, technology risk, supply chain constraints for electrolyser components & direct reduced iron plant equipment, & the challenge of securing long-term offtake agreements for green steel at price premiums that justify the investment.

Regional Rivalries & the Reconfiguration of Raw Material Geographies Dr. Atherton's analysis of the geographic dimensions of the green steel transition revealed a picture of significant regional differentiation, in which the competitive advantages for green iron production are concentrated in a small number of locations that combine abundant renewable energy resources, high-grade iron ore deposits, supportive policy frameworks, & access to seaborne trade infrastructure. He identified the Middle East & Australia as particularly well-positioned regions for green iron production, citing their energy resources & supportive policy frameworks as key enablers. Australia's combination of world-class iron ore reserves in the Pilbara region, abundant solar & wind resources, & proximity to Asian steel markets makes it a natural candidate for the development of green iron export hubs, a vision that has attracted significant interest from both domestic & international investors. The Middle East, particularly Saudi Arabia & the United Arab Emirates, offers comparable advantages in terms of solar energy abundance & existing industrial infrastructure, though Dr. Atherton noted that geopolitical developments in the region continue to pose risks to supply chain stability & trade flows, a reference to the ongoing instability that has periodically disrupted shipping routes through the Red Sea & the Strait of Hormuz. Brazil was specifically highlighted for its potential to supply high-grade iron ore required for direct reduced iron production, a recognition of the country's position as one of the world's largest producers of high-quality iron ore through its Vale-dominated mining sector. The emergence of what Dr. Atherton termed "mega hubs" for green iron production, particularly in regions close to raw material sources, represents a potential restructuring of global steel raw material trade flows, as seaborne trade in direct reduced iron & hot briquetted iron could supplement or partially replace the current dominance of iron ore & coking coal in the raw materials trade. Hot briquetted iron, a compacted form of direct reduced iron that is safer & more economical to transport over long distances, is particularly well-suited to this emerging trade pattern, & its production is already growing at facilities in the Middle East, Venezuela, & Trinidad.

Policy's Pivotal Power & the Preconditions for Paradigm Shift The role of policy in determining the pace & scale of the green steel transition was a recurring theme throughout Dr. Atherton's address, reflecting the fundamental reality that the economics of hydrogen-based steelmaking cannot be made viable through market forces alone in the near term, & that government intervention through carbon pricing, direct subsidies, procurement mandates, & infrastructure investment is a sine qua non of meaningful progress. He emphasised that carbon pricing mechanisms are critical to bridging the cost gap between green hydrogen-based production & conventional steelmaking, a position that aligns the International Iron Metallics Association's analysis the broader consensus among climate economists & industrial policy specialists. The European Union's Emissions Trading System, the Carbon Border Adjustment Mechanism, & the suite of national green industrial policy instruments being deployed across the United States, Canada, Japan, South Korea, & Australia collectively represent the most comprehensive policy architecture for green steel incentivisation ever assembled, yet Dr. Atherton's assessment suggests that even this extensive policy framework is insufficient to close the investment gap at the pace required by climate commitments. The interaction between carbon pricing & hydrogen costs is particularly important: as the carbon price rises, the relative cost disadvantage of green hydrogen-based production narrows, because the carbon cost imposed on natural gas-based & coal-based steelmaking increases their effective production cost. At a carbon price of €100 ($110 USD) per metric ton of CO₂, the cost penalty for conventional blast furnace steelmaking is approximately €200-250 ($220-275 USD) per metric ton of steel, a figure that begins to approach the cost premium of green steel production in the most favourable locations. However, European industrial electricity prices, which are heavily influenced by the carbon price through its effect on gas-fired power generation, simultaneously increase the cost of the renewable electricity required for green hydrogen production, creating a perverse dynamic in which higher carbon prices both incentivise & impede the green steel transition.

Temporal Trajectories & the Tectonic Timeline of Transition Dr. Atherton's most consequential & sobering conclusion concerned the timeline for large-scale adoption of hydrogen-based steelmaking, a projection that carries profound implications for climate policy, industrial investment planning, & the credibility of net-zero commitments made by steel companies & governments alike. He warned explicitly that the timeline for large-scale adoption of hydrogen-based steelmaking may be longer than previously expected, suggesting that significant capacity growth could shift to the late 2030s or early 2040s, a deferral of approximately a decade relative to the optimistic scenarios that dominated industry discourse in the early 2020s. This timeline revision is not merely a technical or financial observation but a statement about the systemic readiness of the energy, infrastructure, & policy ecosystems that hydrogen-based steelmaking requires. The Institute for Energy Economics & Financial Analysis has similarly noted that 2026 could represent a potential inflection point for renewed momentum, but has been careful to condition this optimism on the delivery of policy support, infrastructure investment, & technology cost reductions that are not yet fully secured. The implications of a late-2030s timeline for large-scale hydrogen-based steelmaking capacity are significant for the European Union's industrial decarbonisation architecture, which has established 2030 emissions reduction targets that implicitly assume meaningful progress in steel sector decarbonisation within the current decade. If the bulk of hydrogen-based steelmaking capacity does not come online until the late 2030s, the steel sector's contribution to 2030 targets will depend primarily on incremental improvements in blast furnace efficiency, modest increases in electric arc furnace production using grid electricity, & the partial substitution of natural gas-based direct reduced iron for coal-based ironmaking, none of which can deliver the 30-40% emissions reductions that the most ambitious scenarios project for the sector by 2030. Dr. Atherton concluded that while the pathway to carbon-neutral steelmaking is clear, achieving it will require coordinated efforts in investment, policy support & technological innovation, a formulation that, while measured in its optimism, affirms the fundamental viability of the transition even as it acknowledges the scale of the work that remains to be done.
