How close are we to hydrogen that's cheap and clean?Can clean hydrogen get cheap enough to matter?
or, simply: Can clean hydrogen get cheap enough to matter?or, precisely: How close are we to hydrogen that's cheap and clean?
Electrolysis works; the open question is whether clean hydrogen can reach a few dollars a kilogram and scale to industrial volumes.Clean hydrogen could fuel steel, ships, and fertilizer. First it has to get cheap — and get built at scale.
We are here
Low-emissions share stays tiny — Installed electrolysis passed 4 GW, but low-emissions hydrogen was still about 1 Mt of more than 100 Mt demand. Next up — NEOM targets first ammonia (expected 2027).
01 · Where we stand
Four tests between here and the goal
Each threshold is a falsifiable claim with a named next test. We move the meter only when a result is public.

Next testIEA expects low-emissions supply to exceed 1% in 2026; the next measured production estimate can confirm or falsify that forecast.

THRESHOLDS — Thresholds for Clean Hydrogen.
Scale
Measured Projected Goal region
NOTE — This is the candidate file's recommended metric, but no audited global historical cost series exists. All observations are DOE modeled estimates, not transaction prices; 2024 is the midpoint of a $5-7/kg range. Cost is meaningful only with a stated lifecycle carbon intensity, electricity price, utilization, financing and subsidy boundary. The $2 and $1 points are targets, not achievements.
02 · How we got here
The record behind the verdict
Major events set large; context events set small but never hidden. Everything below the TODAY rule is a schedule, not a result.
Fertilizer Makes Hydrogen Industrial moved the field from synthetic ammonia industrialized to vemork electrolysis opens. The results narrowed the next question without closing it.
1913
Synthetic ammonia industrializedDeployment
BASF's Oppau plant began producing up to 30 tonnes of ammonia per day from synthetic hydrogen and nitrogen.
Scaling Under Carbon Rules moved the field from europe sets electrolyzer targets to eu targets ten million tonnes. The results narrowed the next question without closing it.
2020
Europe sets electrolyzer targets
The EU targeted 6 GW and 1 Mt renewable hydrogen by 2024, then 40 GW and up to 10 Mt by 2030.

The adoption gap
Growing fast, still a rounding error
$5/kg → $1/kglatest modeled cost → goal
NOTE — The left panel shows the build-out; the right panel shows why a fast-growing low-emissions supply can still be almost invisible against a roughly 100 Mt/year market.
