Metallurgical Coal Has Finally Been Classed a Critical Mineral

Key Takeaways

• US adds metallurgical coal to critical minerals list, citing steel dependence.
• Over 70% of global steel still relies on blast‑furnace coke.
• Premium coking coal trades above $230/tonne, far above thermal coal.
• Green hydrogen steel remains under 1% of primary steel production.
• Recycling provides ~30% of global steel, key near‑term decarbonization path.

Pulse Analysis

The United States has formally placed metallurgical, or coking, coal on its critical minerals list, a move that underscores the material’s irreplaceable role in large‑scale steelmaking. More than 70 % of the world’s steel is still produced in blast furnaces that depend on coke derived from high‑grade met‑coal, a feedstock that cannot be substituted by any other fuel or chemical without jeopardizing output. By treating met‑coal as a strategic commodity rather than a generic fossil fuel, policymakers are signaling that domestic supply security is as much a national‑security issue as it is an energy‑transition concern.

The market already reflects this rarity. While global coal extraction approaches 9 billion tonnes a year, metallurgical coal accounts for only 10‑15 % of volume but commands prices of $230‑$250 per tonne—roughly double the price of thermal coal. Tight reserves of low‑ash, low‑sulphur, low‑phosphorus coal are concentrated in a handful of basins, making supply shocks a real risk for sectors ranging from defense to renewable‑energy infrastructure. As governments push for wind‑turbine towers, solar‑farm supports, and LNG terminals, the demand for steel—and therefore met‑coal—remains robust.

Decarbonisation narratives that champion “green” hydrogen steel often overlook the physics of steel chemistry. Hydrogen‑based direct‑reduced iron still requires substantial electricity and ultimately needs carbon to achieve the alloy properties essential for construction and aerospace, rendering it an energy‑intensive detour. In contrast, scrap‑based electric‑arc furnace recycling already supplies roughly a third of global crude steel and offers the most immediate emissions cut. The pragmatic path forward blends secure met‑coal supplies, accelerated scrap collection, and incremental development of low‑carbon primary routes, ensuring that steel remains a reliable backbone for the next wave of infrastructure.
