IEA Hydrogen TCP Task 49 Releases Subtask C Report; Targets 2030s for Commercial Production
The IEA Hydrogen TCP Task 49 Subtask C report provides the clearest global benchmark to date for the natural hydrogen sector, confirming that exploration has now moved into a coordinated international phase with active programs across North America, Australia, Europe, Africa, and Asia.
While Mali remains the only producing natural hydrogen field, the report documents a sharp increase in drilling, subsurface testing, and basin screening in multiple jurisdictions. Early wells in Australia, the United States, and Canada have already recorded high-purity hydrogen shows, but the dataset remains too limited to define commercial play types or establish resource benchmarks.
A consistent pattern emerges: regulatory clarity is the primary driver of exploration activity. Countries that introduced licensing frameworks first are now hosting the majority of drilling programs, while regions without defined permitting pathways remain at the reconnaissance stage.
Geologically, the report reinforces a multi-system model for hydrogen generation and accumulation, including:
- Serpentinization in ultramafic and mantle-derived rocks
- Redox reactions in iron-rich basement formations
- Radiolytic hydrogen in uranium-bearing systems
- Organic and coal-associated generation pathways
However, the central constraint on sector advancement is not hydrogen presence but well density and subsurface data. The report emphasizes that reserve definition will require systematic drilling campaigns, structural mapping, and flow testing comparable to early-stage natural gas basin development.
A notable shift is the entry of national oil companies, mining groups, and major energy firms into hydrogen screening programs, signaling a transition from startup-led discovery toward capital-intensive appraisal.
Based on analog resource cycles, the report indicates that first additional commercial projects beyond Mali are most likely in the early to mid-2030s, contingent on regulatory progress and successful delineation drilling.
