Mining assets: an untapped natural hydrogen opportunity

Natural hydrogen is generated in the Earth’s crust through natural geological reactions.

Iron-rich rocks and mining residues provide ideal conditions for these processes.

Why hydrogen matters for mining

Natural hydrogen could become more than an additional resource for operators. It could help power, fuel and decarbonize mining operations.

01

On-site power generation

Produce low-carbon electricity directly at the mine site.

Natural hydrogen could provide dispatchable power for mining operations, particularly where grid access is limited or electricity is carbon-intensive.

02

Zero-carbon mining fuel

Power heavy-duty mining equipment.

Hydrogen could replace diesel in selected haulage and heavy-equipment applications, reducing both fuel-related emissions and dependence on transported fuels.

03

Low-carbon reductant

Decarbonize mineral processing and metallurgy.

Hydrogen can potentially replace carbon-based reducing agents in certain metallurgical processes, opening a pathway toward lower-carbon metals.

Why mines are strategic

More than 35,000 active mining sites sit on ferrous iron-rich formations capable of generating natural hydrogen.

Known geology

Detailed geological data already exists.

Abundant materials

Iron-rich rocks and residues are everywhere.

Existing infrastructure

Access, permits, power, water and facilities.

Lower exploration risk

Reduce uncertainty and accelerate evaluation.

Sustainable potential

Repurpose residues and reduce environmental liabilities.

New value creation

From mining liability to clean energy asset.

Mining environments with hydrogen potential

  • Ultramafic rocks – high natural reactivity with water
  • Ferrous basalts – common in mafic and volcanic provinces
  • Iron formations (BIF) – ancient, widespread iron-rich deposits
  • Mining residues and tailings – abundant materials, new opportunities
  • Other residuals

Iron-rich environments: a proven source of hydrogen

Natural hydrogen is often associated with iron-bearing formations where water circulates through the crust and interacts with iron-rich minerals, generating hydrogen.

Iron-rich rocks (ultramafic, BIF, ferrous basalts, iron formations) + water (groundwater circulation) + deep water-rock interaction → natural hydrogen, a continuous generation process
