Global Hydrogen Review 2025

Since the 2019 launch of the IEA’s The Future of Hydrogen report, the global conversation on hydrogen has evolved. Once a niche energy carrier, hydrogen is now an important opportunity in global energy systems.

This fifth edition of the Global Hydrogen Review takes stock of the progress to date and explores the challenges ahead, providing a thorough assessment of what could be achieved by the end of this decade. This year’s report also includes a special chapter on Southeast Asia, which explores the region’s near-term potential to produce and use low-emissions hydrogen and hydrogen-based fuels and products – with an assessment of how this could create economic opportunities and reduce import dependencies. 

The report is complemented by updates to the Hydrogen Production and Infrastructure Projects Database – plus the launch of a major new online tracker. This tracker will allow users to further explore announced projects for low-emissions hydrogen production and infrastructure deployment, hydrogen production costs by region and technology, and the more than 1,000 hydrogen policy measures that have been announced or implemented worldwide since 2020.
