A Fraunhofer Import-Cost Study, Applied to LH2 Bunker Fuel: €7-8/kg in 2030, Not €4

Fraunhofer UMSICHT’s RE-Chain study prices hydrogen imports from Spain and Oman all the way to industrial off-takers in Germany’s Rhine-Ruhr region — it says nothing about ships. But its segment-by-segment cost breakdown is exactly the data needed to work out what a vessel bunkering LH2 directly at the import terminal would actually pay, and the answer sits well above what this site’s own Feasibility Tool currently assumes for 2030.

What the Study Actually Prices

The RE-Chain study — commissioned by the Port of Amsterdam and duisport (Duisburger Hafen AG), conducted by Fraunhofer UMSICHT, published August 2026 — evaluates two hydrogen carriers (LH2 and LOHC) shipped from two production regions (Bilbao, Spain and Duqm, Oman) to Amsterdam, then onward by barge, rail, or truck to Duisburg for use by Rhine-Ruhr industrial off-takers — thyssenkrupp and HKM among them. Its cost metric is the Levelized Cost of Transport Service (LCOTS): everything from gaseous H2 at the port of origin to gaseous H2 delivered at Duisburg’s gate, explicitly excluding upstream production cost and downstream distribution beyond the port.

For LH2, that’s five segments: liquefaction, storage (three separate storage legs — preload, Amsterdam, Duisburg — clustered together), maritime shipping to Amsterdam, inland transport (barge/rail/truck to Duisburg), and regasification back to gaseous H2 for the off-taker.

None of that is about ships burning hydrogen as fuel. But the segment structure maps almost perfectly onto the question this site actually cares about: what would it cost a vessel bunkering LH2 directly at Amsterdam — skipping the trip to Duisburg entirely, since a ship wants the hydrogen as liquid fuel, not regasified for a steelworks?

Why “Skip Duisburg” Doesn’t Save as Much as You’d Think

The study’s own segment breakdown (its Bilbao/Duqm cost-share table) is the key input:

The two segments a bunkering ship genuinely avoids — regasification and inland transport — are together only 4–8% of the total LH2 cost. Liquefaction and storage alone account for 65–75%, and both of those costs are already sunk by the time LH2 reaches Amsterdam, regardless of whether the next stop is a ship’s bunker tank or a barge to Duisburg. From a naval architect’s perspective this is the useful, slightly counterintuitive finding: for LH2 specifically, the last-mile distance to the final off-taker barely matters — the cost is dominated by what happens at the production end, before the vessel that carried it across the Atlantic (or from the Gulf) even arrives.

(This is also exactly why the study finds LOHC’s economics work differently — dehydrogenation, the LOHC-equivalent “conversion back to usable H2” step, is 40–46% of LOHC’s total cost, an order of magnitude more than LH2’s 2–4% regasification share. LOHC’s cost structure would make “stop at the import terminal” a much bigger saving than LH2’s does.)

Applying the Study’s Own Numbers

Taking the study’s published year-by-year totals for LH2 delivered to Duisburg (its “DPU” — Delivered at Place Unloaded — figures) and removing an estimated 4–8% for the two segments a bunkering ship skips:

The “bunkered at Amsterdam” column is this site’s own derivation — the study itself only prices delivery to Duisburg. We applied its own segment cost shares (removing regasification and inland transport) to its published Duisburg totals. Treat it as a reasoned estimate, not a Fraunhofer-published figure.

Two things stand out. First, the saving from bunkering at the port instead of shipping onward is small in absolute terms — at most about €0.6/kg even in 2030, narrowing further by 2050 as the underlying cost curve compresses. Second, and more importantly for anyone using this site’s tools: these figures are notably higher than what this site’s own Feasibility Tool currently assumes.

The Cross-Check That Matters

The Feasibility Tool’s fuel-cost model currently uses €4.00/kg for LH2 in 2030, dropping to €2.80/kg by 2035. The RE-Chain-derived bunker cost above is €7.0–7.9/kg for 2030 — nearly double.

This isn’t just an external-study-versus-internal-tool discrepancy either. This site’s own hydrogen price index already reports that European green hydrogen spot prices have been tracking roughly €6.30–7.00/kg through August 2026, with unsubsidised production cost running €5–9/kg before even adding the €1.50–2.50/kg liquefaction premium for LH2 specifically. Today’s actual European spot price, in other words, is already close to what the RE-Chain study projects for 2030 delivered LH2 — which makes the Feasibility Tool’s €4.00/kg 2030 assumption look optimistic by a wide margin against both an independent third-party study and this site’s own separately-maintained price tracking.

We’re flagging this rather than quietly fixing it: the Feasibility Tool’s assumption predates this study and wasn’t built against it, and updating a live calculator’s core price input is a bigger decision than a single blog post should make unilaterally. But anyone using the tool for a real investment case should treat its €4.00/kg 2030 figure as a floor, not a central estimate, until that assumption gets revisited.

Why This Matters

Every LH2 vessel this site tracks — from MF Hydra to the newbuild bulk carrier programmes — ultimately lives or dies commercially on the fuel cost premium over diesel, and that premium is exactly what a study like this one lets you interrogate properly instead of relying on a single flat assumption. The RE-Chain study’s real contribution isn’t a number for ships at all — it’s a structure: production cost, liquefaction, storage/boil-off, shipping, and (for industrial users) reconversion, each separately estimated with its own cost-reduction lever. For a bunkering ship, three of those five levers — cheaper renewable electricity at the production site (the strongest one, up to 30% reduction), liquefaction efficiency, and storage/boil-off management (see our recent coverage of MOF-based cryo-adsorption research aimed at exactly this segment) — are the ones actually worth watching. Inland transport and regasification, the two segments a ship skips entirely, were never going to move the needle much anyway.

Challenges and Open Questions

• The derived bunker-fuel figures are an estimate, not a study result. We applied the RE-Chain study’s own percentage cost shares to its own published totals; Fraunhofer never modeled a ship bunkering scenario directly, and a dedicated LH2 bunkering terminal at Amsterdam might have different storage and boil-off economics than the “preload” storage leg the study actually costed.
• The LH2 barge permit for the Amsterdam–Duisburg route is still pending (EU-wide ADN approval targeted before 2029) — a reminder that even the inland leg this analysis assumes ships skip isn’t yet fully cleared for the industrial users who do need it.
• Route choice matters less than expected. Bilbao offers lower maritime transport cost; Duqm offers lower production cost from stronger renewables. The study finds them in the same order of magnitude — this analysis doesn’t identify a clearly better source region for a ship bunkering at Amsterdam specifically.
• The Feasibility Tool discrepancy needs a real decision, not just a flag. €4.00/kg vs €7.0–7.9/kg is a large enough gap to change a feasibility verdict from green to red for a marginal case — updating the tool’s assumption is a separate task worth doing deliberately, with its own review, rather than folded into this post.
• This study only covers the Spain/Oman → Amsterdam corridor. Other LH2 production regions and import routes (Australia via Kobe, for instance — see our Suiso Frontier coverage) would need their own cost breakdown; nothing here generalises automatically to a different route.
