IEA Global Hydrogen Review 2025

The Global Hydrogen Review is an annual publication by the International Energy Agency that tracks hydrogen production and demand worldwide, shedding light on the latest developments on policy, infrastructure, trade, investments and innovation.

The report is an output of the Clean Energy Ministerial Hydrogen Initiative and is intended to provide an update to energy sector stakeholders on the status and future prospects of hydrogen, and to inform discussions at the Hydrogen Energy Ministerial Meeting organised by Japan.

The sector has progressed significantly since the first publication of the Global Hydrogen Review in 2021. Low-emissions hydrogen production projects have gone from just a handful of demonstrations to more than 200 committed investments for projects that are increasing in number and in scale, reflecting the importance of hydrogen for climate goals, energy security and industrial competitiveness. Nevertheless, growth has not met all of the expectations raised at the start of the decade and remains uneven. Uncertainties about costs, infrastructure readiness and evolving regulatory frameworks all present barriers to faster deployment.

This fifth edition of the Global Hydrogen Review takes stock of the progress to date and explores the challenges ahead, in order to provide a thorough assessment of the level of hydrogen adoption that could be achieved by 2030. This report includes a special chapter on Southeast Asia, exploring the region’s potential for the production and use of low-emissions hydrogen and hydrogen-based fuels and products in the near term.

The report is complemented by updates to the Hydrogen Production and Infrastructure Projects Database, and a new online Hydrogen Tracker that allows users to further explore announced projects for low-emissions hydrogen production and infrastructure deployment, hydrogen production costs by region and technology, and more than 1 000 hydrogen policy measures worldwide announced or implemented since 2020.
