- Thesis — HyStock is not an investment. It is the waste of four hundred and fifty million euros of taxpayer money on a route whose measurement data has been public for three years.
On 4 July 2026 the Dutch cabinet announced it would release €450 million for project HyStock in Zuidwending, Groningen — the first large-scale underground hydrogen storage facility in the Netherlands. Four salt caverns, leached out by Nobian, ready to hold hydrogen that would begin flowing through them in 2032. The Minister for Climate and Green Growth spoke of market failure. She meant something else. She meant that no private investor is willing to carry the bill. The reason is not market failure. The reason is physics.
What the cabinet has decided
The news itself is simple. HyStock receives €450 million. Nobian leaches four salt caverns beneath Zuidwending — a multi-year operation. A hydrogen transport pipeline is planned for 2032. Ultimately thirteen caverns may exist there. The money is directed at three specific risks that "no ordinary investor is willing to bear right now": the uncertain price of the so-called cushion gas, the risk that the storage will not fill fast enough in the first years, and possible permitting delays. Any operational cost overruns remain with HyStock itself.
Read that last sentence again. The taxpayer carries the risk that the facility never becomes profitable. The operator carries the risk that it becomes too profitable. That is not market failure. That is a specific form of state aid that in Brussels is usually called "strategic investment" and in The Hague "industrial transition support". Both terms are euphemisms for the same thing: a private undertaking unwilling to bear a public risk profile is granted public risk capital — without any share for the state in the upside.
That in itself is not the interesting part. What is interesting is the question: which technology is the money underwriting?
The price nobody puts on the table
In On the box or the luggage rack, published on 20 June, one figure was isolated that renders the Dutch hydrogen policy immediately untenable. At the factory gate, without any subsidy, one megawatt-hour of primary energy costs:
| Bron | € / MWh |
|---|---|
| Uranium | €12 |
| Geothermal | €20 |
| Carbon-Alert bio-ethanol | €32 |
| Natural gas | €40 |
| Wood pellets | €45 |
| Grey hydrogen | €67 |
| Fuel oil | €70 |
| Green hydrogen at the Dutch pump | €540 |
Five hundred and forty euros per megawatt-hour. Against thirty-two. Seventeen times more expensive than the cheapest available alternative. This is not a price gap that a more efficient electrolyser or greater scale will erase. Electrolysis structurally requires 52 kilowatt-hours of electricity per kilogram of hydrogen. Compression to 700 bar costs another ten per cent. Transport and storage another fifteen. These loss factors are written into the laws of physics — not into business plans. They do not disappear with €450 million of cavern construction, and they will not disappear with ten years of government persistence.
For heating an average Dutch home this means — as calculated in The nature-adapted analysis — that a household on social assistance would spend more than a quarter of its income on energy alone under a hydrogen transition. That is not a transition. It is household destruction.
The rest of Europe is walking away
For anyone wondering whether this is a partisan Open Vizier reading, three facts that do not come from our desk.
Stellantis — parent of Peugeot, Citroën, Fiat, Opel — exited hydrogen in 2025. Publicly, definitively, citing structural cost disadvantage. Bosch — the German supplier giant — shut down its fuel-cell division in the same period. Volkswagen, Mercedes and Stellantis had been working since 2017 in the IPEN consortium on ethanol fuel cells; that effort was halted when the Brussels and Hague political wind swung to battery-electric and hydrogen. These are not naive parties. They have run the arithmetic that the Minister for Climate and Green Growth apparently did not order to be run.
And in Tochigi, Japan, a Nissan installation has been converting bio-ethanol to electricity at seventy per cent efficiency since 2026. No 700-bar cylinder. No cavern construction. No cushion gas. A liquid in a tank, a catalyst, a membrane — and current flows out at room temperature. Brookhaven National Laboratory demonstrated the underlying cold oxidation in 2009. PNAS in 2022 published a catalyst with 99.9 per cent CO₂ selectivity at a record-low potential of 0.35 volts. In 2025 Brookhaven licensed the technology to Chemcat Japan. Seventeen years between the American scientific breakthrough and the Japanese commercial licence. Europe was in the room during those seventeen years — as a spectator.
The €450 million for Zuidwending is the Dutch way of consolidating that spectator status. Not by correcting an error, but by making it more expensive.
What that same four hundred and fifty million would deliver elsewhere
This is where the debate stops being academic. €450 million is not an abstract figure. It is a concrete pile of money that could have been spent on something else. Four comparisons, all grounded in earlier Open Vizier figures.
Comparison one — Carbon-Alert energy hubs. A 100-kilowatt hub costs €180,000 to build, produces 800,000 kilowatt-hours per year at 9.97 cents, and pays itself back in three years without a single cent of subsidy (The thirty cents that flip Europe). For €450 million you build two thousand five hundred hubs. Together: 250 megawatts of installed capacity, two billion kilowatt-hours per year, and roughly 1,750 permanent jobs in installation, maintenance and operations. Spread across Groningen, Brabant, Friesland and Zeeland — precisely where grid congestion bites hardest.
Comparison two — the rapeseed hectare. In The Rapeseed Multiplier it is shown that a conversion from rapeseed to Carbon-Alert NL raises gross farm income from €1,400–1,900 per hectare to €7,500–12,000 per hectare — a factor of four to eight. At Dutch scale, the launch financing for a 1,000-hectare pilot amounts, on the same analysis, to €15–25 million. With €450 million you fund fifteen to thirty such pilots — or one national roll-out of 20,000 hectares with matching Tier-1 processing infrastructure. That is a quarter of the Dutch nitrogen-crisis hectare resolved in one move — with a farm income that leaves subsidy dependence as a side-note.
Comparison three — BiCRS carbon removal. In The Brussels Consequence Map — BiCRS version the model price for permanent CO₂ removal via anoxic biomass injection in the equatorial band is set at €40 per tonne — against an actual production cost of €22–28 per tonne. For €450 million you buy 11.25 million tonnes of permanent CO₂ removal — nearly a tenth of Dutch annual emissions, permanently and verifiably out of the atmosphere, at half the current EU-ETS price. The hydrogen-cavern alternative delivers no tonnes of removal at all. It delivers a hole in the ground through which something is meant to flow that today is seventeen times more expensive than the alternative.
Comparison four — five to ten thousand European vocational places. In What Brussels really receives the counter-value of a 3,500-hectare Carbon-Alert pilot in the Netherlands, Germany and France is calculated at €15–25 million via Horizon Europe. After the agricultural pilots and the energy hubs, enough remains of the €450 million to build the complete Dutch vocational curriculum for ethanol operations and SOFC maintenance across five hundred training colleges — putting two generations of unemployed metalworkers and installers directly to work in the industry now forming in Japan and Korea.
The real anatomy of the waste
Add it up. In the "political luggage rack" scenario — as the previous triptych called it — the €450 million for HyStock delivers, after ten years, a cavern complex that stores a molecule whose end-user price is seventeen times higher than the best alternative. In the "coachman" scenario the same money delivers 2,500 energy hubs, 20,000 hectares of agricultural transformation, 11 million tonnes of permanent carbon removal, and the complete vocational training pipeline for the industry we spent seventeen years watching others build. The choice is not ideological. It is arithmetic.
The responsible minister — Climate and Green Growth — speaks of market failure. But there is no market failure. There is a market reading the price signals and walking away. That market is called Stellantis. That market is called Bosch. That market is called Volkswagen. They saw the €540-per-megawatt-hour figure and left. What the cabinet is doing is not correcting market failure. What the cabinet is doing is artificially sustaining a physically untenable route with taxpayer money — exactly as it earlier did with SDE wind subsidies, gigafactory support and hydrogen corridors, all three now documented as financial sunk costs.
The three silent assumptions that make this waste possible
Beneath every €450 million state expenditure on a loss-making route lie three silent assumptions that no one in the Dutch parliament tests explicitly. One — that hydrogen "will remain necessary for industry regardless". That argument holds for exactly two applications (refinery hydrocracking and ammonia synthesis) and fails for mobility, heating, and stationary electricity. For those three, ethanol-SOFC is demonstrably cheaper. Two — that "the hydrogen learning curve will yet make it cheaper". This is a curve that after fifteen years of subsidy has not achieved even twenty per cent cost reduction, against an ethanol learning curve of seven to nine per cent per year since 2020, documented by IEA Bioenergy Task 39. Three — that "we should not put all our eggs in one basket". This fallacy conceals that the current basket contains a single egg — battery plus hydrogen — while omitting precisely the third egg (ethanol-SOFC) that would make the diversification argument sound.
What a responsible minister could do today
The €450 million has been committed, not spent. The decision sits with the Dutch parliament. A responsible minister would do three things today. One — pause the commitment until an independent recalculation on eu-bicrs.openvizier.org has been run, testing the same €450 million against alternative deployment in bio-ethanol-SOFC scaling. Two — send a parliamentary letter that explicitly acknowledges that green hydrogen at the Dutch pump costs €540 per megawatt-hour and ethanol-SOFC costs €32, and that policy is being reconsidered accordingly. Three — publicly state that the seventeen-year Asian lead on ethanol-SOFC can only be closed if the Netherlands chooses now — in 2026, not in 2032 — to produce in Groningen, Brabant and Friesland.
These three steps cost no additional money. They save €450 million. They also unlock a technological route capable of delivering 350,000 European jobs without a single cent of subsidy.
The bill presented to the voter
What remains is the question of who pays. €450 million of taxpayer money is not neutral money. It comes from households which, according to the calculation in The nature-adapted analysis, spend one thousand euros per year more on energy under the government track than under the ethanol-CHP track. Those same households now co-finance, through their taxes, a cavern build that deepens the energy poverty in which they already sit rather than relieving it. For the social-assistance household Sandra — €5,667 per year in hydrogen-transition energy costs against her current €1,824 — this is not a fiscal nuance. It is existential.
The question the Dutch parliament must answer next week is not whether Zuidwending yields a technically interesting cavern. It will yield a technically interesting cavern. The question is whether the Netherlands can afford €450 million to cement seventeen years of Asian lead on the cheapest available energy route — when the same money spent elsewhere would close exactly that gap.
The answer is arithmetic. And the answer is no.
