E-fuels Market Trajectory and Transport Decarbonisation

The global e-fuel market is forecast to grow from USD 1.76 billion in 2024 to USD 26.55 billion by 2034, representing a compound annual growth rate of 11.5 per cent, according to Fortune Business Insights. This expansion is driven by aviation, maritime, and hard-to-electrify road segments where drop-in synthetic fuels offer immediate compatibility with existing combustion infrastructure. Range-extender engines—compact internal-combustion units that recharge battery packs in electric vehicles—sit at the intersection of this transition, potentially running on e-methanol, e-diesel, or synthetic gasoline derived from green hydrogen and captured CO₂.

Belgium’s BE.Hydrogen programme, overseen by Minister Jean-Luc Crucke and coordinated by Belspo with the Geological Survey of Belgium, is mapping natural hydrogen accumulations in the Hercynian basement and former coal basins of Hainaut and Liège. AI-driven geological modelling is beginning to refine exploration targeting by correlating structural lineaments, fault permeability, and ultramafic rock distributions with serpentinisation zones that generate native H₂. Should commercial flows be confirmed, Belgian natural hydrogen could supply local Power-to-Liquid plants more cost-effectively than electrolytic hydrogen, reducing the carbon intensity and CAPEX of e-fuel production.

Range Extenders in a Synthetic-Fuel Ecosystem

Range-extender architecture—exemplified by projects such as Horse Powertrain’s anticipated hydrogen-combustion units—depends on reliable, low-carbon liquid or gaseous fuel supply chains. As RED III and ReFuelEU Aviation mandates take effect, e-fuel volumes are expected to scale rapidly across Europe, creating a regulatory pull for drop-in synthetics in light- and heavy-duty mobility. Belgium’s geological assets, if validated, position the country to anchor regional e-fuel hubs that could feed both aviation blending mandates and range-extender fleets, bridging electrification gaps in logistics and rural transport where battery-only solutions face range or payload constraints.

Strategic Convergence: Indigenous Hydrogen and Synthetic Fuels

The convergence of natural hydrogen discovery, AI exploration tools, and e-fuel market growth offers Belgium a dual pathway: export indigenous H₂ or integrate it into domestic Power-to-Liquid value chains that supply SAF, e-diesel, and e-methanol. Range-extender engines, though absent from this period’s headlines, remain a potential off-taker for such fuels, particularly in commercial vehicle segments where full battery electrification remains economically challenging. Minister Crucke’s focus on the Greater Region’s geological potential aligns with broader European energy security and decarbonisation goals, ensuring that Belgian natural hydrogen exploration is not an isolated geological curiosity but a strategic input to the continent’s synthetic-fuel infrastructure.
