Carboniferous Conundrum: Why Steel Still Burns Coal in a Battery Age Steel production is among the most energy-intensive industrial processes on Earth, & it remains almost entirely tethered to fossil fuels. The sector consumes energy for two fundamental purposes: the chemical energy required to strip oxygen from iron ore & turn it into metallic iron, & the high-temperature heat demanded at every stage of the value chain, from blast furnaces to reheating furnaces, annealing lines & galvanising baths. A new report from the Institute for Energy Economics & Financial Analysis, authored by energy finance analyst Soroush Basirat, argues that electrification can address both requirements & should be elevated to a priority pathway for cutting emissions, reducing fossil fuel dependence & insulating producers from energy supply shocks . The scale of the task is laid bare by one statistic: electricity accounts for less than 12% of the steel sector's total energy consumption, far below the roughly 20% share electricity holds in global final energy use. Coal, principally metallurgical coal used in coke ovens & blast furnaces, dominates the remainder, alongside natural gas for reheating & direct reduction. The sector emits roughly 2.6 billion metric tons of CO₂ a year, about 7% of global energy-system emissions, & the average blast furnace route releases about 2.3 metric tons of CO₂ per metric ton of crude steel. "Electrification should be viewed not simply as a decarbonisation pathway for steel, but as an opportunity to improve energy efficiency, reduce fossil fuel dependence, strengthen energy security & increase the flexibility & resilience of steel production," Basirat wrote. The report lands as Türkiye, host of the thirty-first Conference of the Parties in Antalya next month, has proposed a 35% by 2035 target for electricity's share of final energy consumption, a goal that cannot be met unless heavy industry, steel foremost among it, plugs in .

Scrap's Salutary Sovereignty: Secondary Steelmaking's Silent Surge The most mature form of steel electrification is already running at scale. Electric arc furnaces, which melt recycled scrap using high-current electric arcs, account for about 29% of global crude steel output, & the share is far higher in some markets: around 70% in the United States, more than 90% in Türkiye itself, & about 40% in the European Union, against only around 10% in China & 50% in India where much of the electric capacity still runs on coal-based direct reduced iron rather than scrap. The report notes that increasing scrap use & expanding secondary steelmaking will drive a measure of electrification naturally, because an electric arc furnace running on scrap uses roughly 0.4 to 0.6 megawatt-hours of electricity per metric ton & emits a fraction of a blast furnace's CO₂, with the exact figure depending on grid intensity . Scrap availability is the constraint rather than technology. Global scrap supply is expected to grow from about 750 million metric tons a year today to more than 1 billion metric tons by 2050 as the stock of steel in buildings, vehicles & infrastructure built during China's construction boom reaches end of life, but scrap cannot meet total demand of about 1.9 billion metric tons, nor can it easily supply the cleanest grades required for automotive sheet or electrical steel, where residual copper & tin from recycled material degrade quality. The analysis therefore treats secondary steelmaking as a necessary but insufficient pillar, & points out that policies restricting scrap exports, improving collection & sorting through sensor-based technology & encouraging design for recyclability can raise both the quantity & quality of material available to electric furnaces .

Hydrogen's Hegemony in Reduction, Humility in Heat Primary steelmaking from iron ore presents a knottier challenge, & here the report draws a sharp line between two roles for hydrogen. As a reducing agent in direct reduced iron plants, hydrogen produced by electrolysis using renewable electricity achieves what the authors term indirect electrification: electrons make hydrogen, hydrogen strips oxygen from ore, & the resulting sponge iron is melted in an electric furnace. Projects such as Stegra in Sweden, the first commercial-scale plant designed around this route, & pilots in Germany, Spain, Saudi Arabia & Oman demonstrate that the chemistry works. The report states that hydrogen will be essential for iron ore reduction . Its verdict on hydrogen as a fuel for heat is markedly cooler. Burning hydrogen to generate process heat is feasible, but the round trip, from electricity to hydrogen through electrolysis at perhaps 70% efficiency & then back to heat through combustion, wastes energy that direct electric heating would deliver at close to 100% conversion. Green hydrogen also remains expensive, at roughly $4 to $8 per kilogram in most markets against the $1 to $2 needed for parity against fossil alternatives, so spending it on heat that electricity can supply directly makes little economic sense. The report concludes that hydrogen is likely to be most valuable as a reductant rather than a fuel, a finding echoed in earlier Institute for Energy Economics & Financial Analysis work on green steel opportunities in the Middle East & North Africa, where cheap solar power & proximity to iron ore & European markets favour hydrogen-based direct reduction .

Electrochemical Epiphany: Ironmaking Without Carbon or Hydrogen Looking further ahead, the report surveys a frontier where electricity could reduce iron ore directly, bypassing both coal & hydrogen. Electrochemical ironmaking technologies use electric current to pull oxygen from iron oxide in a cell, in a process conceptually similar to the Hall-Héroult method that transformed aluminium production in the late nineteenth century. Two approaches lead the field. Molten oxide electrolysis, pursued by Boston Metal, dissolves ore in a molten electrolyte at about 1,600°C & produces liquid iron at the cathode & oxygen at the anode; the company commissioned an industrial-scale cell in Massachusetts in 2025 & plans a commercial plant in Brazil. Low-temperature aqueous electrolysis, developed by Electra in Colorado & by Siderwin in Europe, dissolves ore in an acidic or alkaline solution at around 60°C & plates out iron, a route that can run intermittently & so pairs well alongside variable renewable power. The report is careful to temper expectations: these technologies remain at an early stage of development & will require further progress, demonstration & commercialisation before they can be deployed at scale . Their appeal, if they mature, is considerable. They would eliminate the need for coke ovens, blast furnaces, electrolysers & hydrogen storage alike, cut the number of process steps & potentially use low-grade ores that hydrogen-based direct reduction struggles to handle. Analysts caution that commercial deployment at the scale of millions of metric tons a year is unlikely before the mid-2030s, so near-term emissions cuts must come from scrap, hydrogen reduction & heat electrification instead.

Thermal Thresholds: The Thousand-Degree Dilemma What distinguishes steel from most other industries seeking to electrify is temperature. In food, chemicals, paper & textiles, a large share of heat demand sits below 200°C, where industrial heat pumps can deliver two to four units of heat for each unit of electricity & payback periods are short. Steel offers no such shortcut. The report finds that almost 70% of the sector's total energy consumption is used to provide process heat at temperatures above 1,000°C, in blast furnaces, basic oxygen converters, reheating furnaces that bring slabs & billets to rolling temperature, & heat-treatment lines . Technologies to supply such heat electrically exist or are emerging: induction heating, already standard for billets & bars in some mills, electric resistance & radiant-tube furnaces, plasma torches & thermal energy storage systems that charge on cheap electricity & discharge high-temperature heat on demand. Induction reheating can reach 90% efficiency against 50% to 60% for gas-fired furnaces, & companies such as Rondo & Antora are building firebrick or carbon-block heat batteries that store electricity as heat above 1,500°C. Yet the report stresses that further investment, demonstration & deployment are needed before these become mainstream, because retrofitting a 300-metre reheating furnace in a working mill is costly, grid connections of hundreds of megawatts are slow to secure & many mills already own gas furnaces alongside decades of remaining life. The downstream value chain, from hot rolling to coating, is where the report sees the largest untapped electrification opportunity precisely because it has attracted the least attention compared alongside the headline battle over blast furnaces .

Geopolitical Gravitas: Energy Security as Electrification's Spur The case for electrification, the report argues, has moved beyond carbon accounting. Recent conflicts & disruptions to major fossil fuel trade routes have exposed how dependent steelmakers are on imported coal & gas. The analysis maps fossil fuel dependence across regions that together produced about 90% of the world's steel in 2025, & finds South Korea, Japan & the European Union to be the most exposed, importing nearly all their metallurgical coal & liquefied natural gas. China, the world's largest producer, imports a substantial share of its coking coal from Australia, Mongolia & Russia. The United States & Russia are net exporters of both metallurgical coal & gas, giving their mills a structural advantage, while in Southeast Asia Thailand imports gas & Indonesia & Malaysia export it . The disruption of Red Sea shipping in 2024, European gas price spikes after 2022 & tariff wars over steel itself have all driven home the point. Electrification, especially when powered by domestic renewable generation, converts an import dependency into a domestic supply chain. Türkiye exemplifies the logic: its steel industry is overwhelmingly electric-arc based but its electricity still leans on imported gas & coal, so the 35% by 2035 electrification target only delivers security if paired alongside the country's rapidly expanding wind & solar fleet . The report frames this as a convergence of climate & industrial policy, in which steel electrification serves sovereignty as much as sustainability.

Pecuniary Paucity: The Investment Imbalance Industry Confronts Money is the binding constraint, & the report is blunt about an imbalance. The International Energy Agency projects that annual global investment in electrification will rise from about $320 billion today to around $1 trillion by 2035, yet all industrial sectors combined are expected to receive less than 3% of that total, alongside far larger shares flowing to transport, through electric vehicles & charging, & to buildings, through heat pumps & appliances . Steel faces higher upfront costs than most sectors, longer asset lives that lock in existing kit, & thinner margins amid global overcapacity estimated at more than 600 million metric tons a year. It also often lacks the targeted incentives available elsewhere: electric vehicle buyers receive subsidies in dozens of countries, while a mill seeking to replace a gas reheating furnace alongside induction heating typically does not. The report calls for targeted policy support, infrastructure investment & market incentives to overcome upfront costs & technology risks, singling out indirect electrification through green hydrogen & direct electrification of high-temperature downstream heat as the areas needing the most help . Instruments include carbon pricing alongside border adjustments such as the European Union's mechanism, which from 2026 charges importers for embedded emissions, contracts for difference that bridge the cost gap for green steel, public procurement standards for low-emission steel in infrastructure, & accelerated grid connection for industrial electrification projects. Earlier Institute for Energy Economics & Financial Analysis research on India found that decarbonisation readiness varied widely among producers, alongside access to finance the decisive factor .

Flexibility's Fortune: Furnaces That Follow the Sun The report's final argument reframes a perceived weakness as a strength. Critics of electrification point to the difficulty of guaranteeing uninterrupted clean electricity for processes that run continuously, & to the risk that mills end up drawing coal-fired power at night. Battery storage, whose costs have fallen about 90% in a decade, is steadily improving grids' ability to supply reliable low-emission power. But the report emphasises that new electric steelmaking technologies also offer demand-side flexibility: plants can reduce or shift consumption during periods of high prices or peak system demand, & ramp up when wind & solar are abundant & electricity is cheap . Electric arc furnaces can already modulate load within minutes & some operators in Spain & Germany earn revenue from grid-balancing markets. Electrolysers producing hydrogen can run preferentially during midday solar peaks, storing hydrogen for continuous use in the reduction shaft. Thermal batteries can soak up surplus renewable electricity & release heat to rolling mills hours later. Low-temperature electrochemical ironmaking is inherently interruptible. This flexibility improves the economics of electrification by lowering average electricity costs, & simultaneously helps grids absorb higher shares of variable renewables, turning steelmakers from passive consumers into active participants in the power system . The report concludes that electrification should be seen as a comprehensive industrial strategy, delivering efficiency, security, flexibility & resilience alongside emissions reductions, & that COP31 in Antalya offers the moment to place steel's electrification at the centre of global industrial climate policy .
