The 2026 Regulatory Landscape: ReFuelEU and RED III Deadlines
ReFuelEU Aviation, in force since January 2024, imposes escalating sustainable aviation fuel (SAF) blending obligations starting at 2% in 2025, rising to 6% by 2030 and 70% by 2050. Within that 2030 tranche, a 1% minimum share must come from synthetic Power-to-Liquid e-fuels—hydrogen-based kerosene. RED III, meanwhile, sets a binding 42.5% renewable energy target for 2030, with specific sub-targets for transport (29%) and industry (1.6% annual increase). Both instruments assume hydrogen supply will originate from grid-connected electrolysis fed by wind and solar, creating fierce competition for renewable electrons and driving up capital costs.
Natural hydrogen—produced by serpentinisation of olivine-rich rocks, as documented in Lorraine’s Folschviller boreholes and Canada’s PNAS serpentinite study—offers a geologically sourced alternative with near-zero operational emissions. Yet RED III’s Article 27 renewable-fuel-of-non-biological-origin (RFNBO) criteria mention only electrolytic hydrogen meeting additionality, temporal correlation, and grid-carbon thresholds. White hydrogen, extracted rather than synthesised, does not fit the electrolysis mould, leaving it unclassified and therefore ineligible for compliance accounting under current drafting.
Lorraine, HY4Link, and the Greater Region Compliance Puzzle
REGALOR II—the French geological survey drilling programme in the Lorraine Basin—and Belgium’s BE.Hydrogen initiative have together mapped substantial natural-hydrogen reservoirs beneath the Greater Region. The HY4Link pipeline, planned to traverse Luxembourg, Saarland, Lorraine, and Wallonia, is designed to aggregate both electrolytic and geological flows, yet its business case depends on regulatory clarity: will white hydrogen molecules count toward ReFuelEU’s 1% e-fuel mandate or RED III’s 29% transport sub-target? Without explicit inclusion, off-takers cannot sign power-purchase-style hydrogen agreements, and project finance stalls.
Compliance directors eyeing 2030–2032 blending gates face a paradox: Lorraine’s natural hydrogen could supply feedstock for Fischer-Tropsch e-kerosene at lower cost and carbon intensity than grid-fed electrolysis, yet no compliance credit accrues. Marketing teams promoting ‘geological e-fuels’ risk greenwashing accusations in the absence of a recognised sustainability-certification pathway. The solution requires either a RED III amendment recognising low-carbon geological hydrogen or a delegated act under ReFuelEU’s Article 25 that expands RFNBO definitions to include serpentinisation-derived H₂.
Bridging the Gap: Policy Recommendations for 2027–2030
Three steps could align natural hydrogen with EU compliance calendars. First, the European Commission should commission a life-cycle-assessment study comparing white hydrogen’s well-to-gate emissions against electrolytic benchmarks, using Lorraine and Canadian field data. Second, RED III’s next review—scheduled for 2028—should introduce a ‘geological RFNBO’ category with carbon-intensity and methane-leakage thresholds. Third, HY4Link and similar cross-border projects need a fast-track certification pilot under the Connecting Europe Facility, demonstrating that mixed electrolytic-geological flows can meet both ReFuelEU and CBAM carbon-border-adjustment requirements without double-counting. Until then, compliance officers will plan around a hydrogen supply map that omits the very resource geology has delivered beneath their feet.
