46 megawatts. That is what Europe connected in the first half of 2026.

Against 177 MWel in the same period of 2025, and with the average commissioned project falling from 18 MWel to 5 MWel. This is not a slowdown in growth. It is a change of scale downwards, and the diagnosis of why has moved from cost to something harder to fix.

The €/kW problem: why the same electrolyser costs €323 and €3,050 per kW

Three published figures for the same alkaline technology, all of them correct, differing by a factor of eight. The gap is not disagreement between analysts — it is the calculation boundary, and almost nobody states it.

A Chinese stack is four to six times cheaper. It moves your LCOH by 3 to 13%.

Two beliefs carry a lot of hydrogen models: that the learning curve will bring costs down, and that Chinese equipment will accelerate it. Both are now testable. The European Commission's own assessment puts the second one at 3–13%, and the factories making the equipment are running at about 10%.

An LCOH is twelve choices, not one number

Seven techno-economic tools were given identical inputs for the same project. They returned €5.86 to €8.71 per kilogram. No published standard prescribes an LCOH methodology — so here is the checklist, and what each major publisher actually chooses.

The hydrogen pipeline cost everyone quotes is four years old and rests on a footnote

€0.11–0.21 per kilogram per 1,000 km is the number in every transport slide. Its own source says, in footnote 23, that it assumes 5,000 hours a year of utilisation — and has not restated it since April 2022, through a 47% rise in steel pipe prices.

Three countries hold 77% of Europe's hydrogen storage potential. Yours may not be one.

The storage line in a hydrogen model is usually one number. It is not a number. It is a question about the rock under the site, a question about how often the cavern is cycled, and a nine-year permitting timeline that does not fit inside a project schedule.
