Substitutes

Substitutes and Alternatives for Metallurgical Coal

The availability of viable substitutes is a key factor in assessing Metallurgical Coal's criticality. Across its 2 primary applications, substitution options range from commercially viable alternatives with performance trade-offs to applications where Metallurgical Coal currently has no effective substitute.

Substitution Analysis by Application

The following table details available substitutes for Metallurgical Coal across its primary applications, including the trade-offs involved:

Performance Trade-offs

In most applications, substituting Metallurgical Coal involves measurable performance penalties. Green hydrogen can replace coking coal in DRI-EAF steelmaking but costs 30-50% more at current H2 prices; transition will take decades due to blast furnace infrastructure lifespan. In high-performance applications such as steelmaking (blast furnace coke), these trade-offs can be particularly significant.

Research and Development

Active research programs are underway to develop improved substitutes and to reduce the amount of Metallurgical Coal required per unit of product (thrifting). However, timelines for commercializing new alternatives typically span years to decades.
