Hydrogen delivered to a locomotive costs roughly €14 per kilogram in Europe — more than four times the headline production price of €2–3/kg — a gap that decarbonisation expert Michael Barnard says is burying any commercial case for hydrogen-powered rail freight on the continent.

The Vancouver-based analyst's verdict follows a string of European rail trials that have failed to deliver a viable hydrogen operation. Roughly 42.4% of Europe's railway network remains non-electrified, the segment today handled largely by diesel traction that operators want to replace.

What makes hydrogen so expensive?

Barnard said the gap between factory-gate and delivered prices comes from costs that pro-hydrogen studies routinely omit.

"This is where cheap-hydrogen projections often fail: they turn a production cost into a delivered fuel cost," he said. "I've reviewed European studies where apparent €2–3/kg hydrogen becomes closer to €8/kg delivered industrially and roughly €14/kg for transportation once omitted system costs are restored."

Those system costs include electrolyser balance-of-plant, compression, storage, transport and dispensing. Higher electrolyser utilisation spreads capital over more kilograms of hydrogen, Barnard noted, but it also pulls operators into running when grid electricity is not unusually cheap.

Why doesn't the non-electrified network need a new fuel?

European manufacturers already sell freight locomotives with on-board batteries sized for terminals, sidings and short gaps in catenary — a configuration Barnard says erodes hydrogen's core pitch.

"'Non-electrified' does not mean 'needs a fuel,'" he argued. "It means deciding how much of the route should be wired and how much onboard storage is needed for the rest. Partial electrification plus batteries means you don't need wires over every siding, terminal, bridge or lightly used kilometre."

Rail freight hydrogen only delivers value where an electrolyser is already producing at sub-economic output. "Rail freight might improve the utilisation of a stranded electrolyser," Barnard said. "It does not make its hydrogen cheap."

Is battery-electric already pulling ahead?

German state operator Deutsche Bahn offers the clearest signal, having purchased a dedicated hydrogen fleet and supporting infrastructure in Lower Saxony before running into "operating and cost problems" and selecting batteries for its next major diesel-replacement phase, Barnard said.

Hydrogen in any fuel-cell locomotive is an electricity round-trip: electricity to hydrogen, hydrogen to fuel cell, fuel cell to battery buffer, battery to traction motors. With European manufacturers now selling high-power battery-electric freight locomotives, that round-trip has nothing left to justify, he argued.

"I see no evidence they are approaching commercial competitiveness," Barnard said of hydrogen fleets. "Hydrogen rail freight is not competing with a theoretical future battery. It is competing with mature overhead electrification and rapidly improving batteries, using an electricity system that railways already have."

What would actually change the verdict?

Barnard sketched out the evidence threshold that would shift his position: a sizeable commercial freight fleet running for several years on genuinely low-carbon hydrogen, without exceptional operating subsidies, with high availability and audited whole-system costs below battery-plus-electrification — followed by the operator committing its own capital to a substantially larger second fleet.

Until that record exists, falling electrolyser prices alone won't tip the math. Lower stack costs compress only the production leg of the chain, not the compression, storage and dispensing layer that makes hydrogen deliverable to a locomotive tank.

A separate green hydrogen pilot launched recently at the Ports of Genoa with FS Logistix will add another data point to that test. Whether it produces hydrogen at a delivered price operators can absorb remains the open commercial question for the rest of the decade.
