Hydrogen Hub
Definition
A hydrogen hub is a geographically concentrated network of clean hydrogen producers, consumers, and connective infrastructure — storage, pipelines, and refuelling — designed to build supply and demand together and drive down costs through shared infrastructure. The model is institutionalised in the US Department of Energy's Regional Clean Hydrogen Hubs programme (up to USD 7 billion) and in the EU's "hydrogen valleys", regional ecosystems spanning the whole hydrogen value chain.

Overview
What it means
Hydrogen faces a chicken-and-egg problem: producers won't invest without demand, users won't switch without supply. Hubs solve this by contracting both sides in one region — typically around ports, industrial clusters, or renewable resources — while governments de-risk first movers.
Whether hubs anchor genuinely low-carbon hydrogen or entrench fossil-based production with carbon capture is the central integrity question.
How it is used
The concept structures national hydrogen strategies, industrial-decarbonisation planning, and public funding for clean-hydrogen deployment.
Why it matters
Hubs are where the hydrogen economy will either achieve liftoff or reveal its limits — the scale test for hydrogen's climate claims. **Note:** 1386 Hydrogen corridor and 1391 Hydrogen valley merge into this entry as regional-network variants.
