E-Fuel Market Growth and Feedstock Demand

Research published in January 2025 projects the e-fuel market will reach USD 321.05 billion by 2033, driven by net-zero sustainability priorities and technology convergence. Range-extender engines—which pair electric drivetrains with small combustion units burning synthetic fuels—are among the applications fuelling this growth. Europe has set a 2026 carbon-neutral ultimatum for e-fuels, requiring all synthetic fuels sold in the bloc to demonstrate full lifecycle neutrality by that date. This regulatory pressure is accelerating investment in hydrogen feedstock, both electrolytic and geological.

Belgium’s BE.Hydrogen programme, overseen by Belspo and supported by Minister Crucke, is investigating natural hydrogen occurrences in the Hercynian basement and former coal basins of Wallonia and the Greater Region. AI-assisted geological mapping and exploration targeting are beginning to identify prospective zones where hydrogen may migrate from deep basement structures into shallower sedimentary traps—a process that could yield low-cost, low-carbon feedstock for the e-fuel industry.

Belgian Coal Basins and the Hercynian Basement

The Geological Survey of Belgium (GSB) has identified the Hercynian basement—a Paleozoic tectonic complex underlying much of southern Belgium—as a priority target for natural hydrogen exploration. Historic coal mining in the Liège and Hainaut basins left behind extensive subsurface data, which is now being reinterpreted for hydrogen prospectivity. Early-stage work suggests that serpentinisation reactions and radiolysis in basement rocks may generate hydrogen that migrates into overlying Carboniferous strata.

If commercial flows are confirmed, Belgian natural hydrogen could supply power-to-liquid plants across the Greater Region, reducing reliance on grid-intensive electrolysis. The 2026 carbon-neutral deadline for e-fuels in Europe means that any hydrogen source with a demonstrably low emissions footprint—geological hydrogen included—will be highly valued. Range-extender vehicle manufacturers and SAF producers are already seeking long-term feedstock contracts to meet ReFuelEU and RED III mandates.

Policy and Market Outlook to 2030

Scenarios published by Frontier Economics in January 2025 outline market ramp-up pathways for e-fuels in road transport, with 2030 identified as a critical inflection point. Belgium’s participation in this ramp-up will depend on its ability to secure affordable hydrogen, whether green or geological. The BE.Hydrogen programme’s exploration phase is expected to deliver initial resource estimates by late 2026, informing decisions on pilot production and integration with cross-border e-fuel supply chains.

Minister Crucke has emphasised that natural hydrogen exploration aligns with Belgium’s broader energy transition strategy, offering a domestic alternative to imported feedstock and supporting the decarbonisation of hard-to-abate sectors. As range-extender engines and other e-fuel applications scale, Belgium’s geological assets in the Hercynian basement may prove a strategic advantage in the race to meet 2030 and 2033 market targets.
