What BE.Hydrogen Actually Is — and Is Not

On 27 March 2026, Belgium’s Council of Ministers approved a €3.5 million national exploration programme, administered by the Royal Belgian Institute of Natural Sciences, to assess whether natural — or ‘geological’ — hydrogen exists in Belgian subsoil. To be precise: this is a survey, not a discovery. No natural hydrogen accumulation, flow, or commercially exploitable resource has been confirmed on Belgian territory. Compliance directors should record that distinction carefully; premature assumptions about Belgian natural hydrogen supply would be a material planning error.

The relevance for aviation and transport lies in what a positive result could eventually mean. Natural hydrogen, unlike electrolytic green hydrogen, requires no renewable electricity to produce. That eliminates the single largest cost and efficiency objection to hydrogen-derived fuels — the well-to-wheel energy loss of roughly 13–20% for e-fuel powertrains compared with 70–80% for battery-electric vehicles. If geological hydrogen were confirmed and commercialised, it could supply future Power-to-Liquid SAF and hydrogen-blended aviation fuel chains at a fraction of today’s energy cost.

The Aviation and Transport Compliance Angle

For airlines and OEMs building compliance roadmaps toward ReFuelEU Aviation mandates and RED III obligations, the supply-side question is existential: where does affordable, low-carbon hydrogen come from at scale? Electrolytic green hydrogen remains expensive; blue hydrogen carries carbon-capture risk (see the IEA’s note that many projects are slipping toward 2035). A geological hydrogen source in Western Europe — should BE.Hydrogen’s surveys eventually confirm one — would represent a structurally different feedstock option for SAF producers operating under EU blending mandates. Compliance calendars for 2030–2032 are being written today; supply assumptions baked in now will be difficult to revise later.

It is also worth noting that the efficiency objection to hydrogen-derived e-fuels — central to the Transport & Environment and ICCT critiques of Power-to-Liquid pathways in road transport — weakens considerably for aviation. Batteries cannot serve long-haul aviation, deep-sea shipping, or heavy industry at current energy densities. For those sectors, the cost of hydrogen is the variable that matters most, and geological sourcing could change that variable materially.

What Compliance and Sustainability Teams Should Do Now

The practical action for compliance and marketing directors is scenario planning, not procurement. BE.Hydrogen is a multi-year geological survey; any commercial hydrogen resource, if confirmed, would require further appraisal, regulatory permitting, and infrastructure build-out well beyond a 2030 horizon. However, the programme’s existence signals that EU member states are actively diversifying their hydrogen origin strategies — relevant context for any airline or fuel supplier modelling SAF feedstock costs against ReFuelEU blend trajectories through 2035.

Monitor the Institute of Natural Sciences’ programme outputs. If early borehole or seismic data from BE.Hydrogen suggests prospective geology, that information will move fast through energy-sector networks. Being positioned to interpret it — rather than react to it — is the mark of a mature compliance function.
