Technical FAQs 4

What is the global hydrogen review?

The Global Hydrogen Review was prepared by the Energy Technology Policy (ETP) Division of the Directorate of Sustainability, Technology and Outlooks (STO) of the International Energy Agency (IEA). The study was designed and directed by Timur Gül, Chief Energy Technology Officer.

Where can I find IEA hydrogen production projects?

production can be found in the new Hydrogen Tracker available on the IEA website. Source: IEA Hydrogen Production Projects Database (September 2025). Only around 10 Mtpa of low-emissions hydrogen production are almost certain or have strong potential to be operational by 2030.

Which country has the most hydrogen refuelling stations in the world?

Source: IEA (2025), Global Electric Vehicle Outlook 2025. China leads the global roll-out of hydrogen refuelling stations, whereas station availability has declined in the United States, due to reliability and hydrogen supply issues.

Why is a hydrogen market integrated in the National Energy Modeling system (NEMS)?

Representing an integrated hydrogen market in the National Energy Modeling System (NEMS) allows us to analyze the potential growth in hydrogen use as a clean energy source and to reflect current laws and regulations in our projections.
