Global Hydrogen Review 2025 Production highlights
…the 49 Mtpa estimated in the Global Hydrogen Review 2024 (GHR-24).More projects are reaching final investment decision (FID), although the total production capacity reaching this stage in 2024 remained at the same level as in 2023. Persisting technical and regulatory barriers, financial obstacles and challenges in securing reliable offtake, in particular, continue to delay and occasionally completely stall project progress.Despite announced delays and cancellations, low-emissions hydrogen production is expected to increase significantly by 2030. Based only on projects that are operational, have already reached FID or are under construction, low-emissions hydrogen production can reach more than…

Global Hydrogen Review 2025 Executive summary
…using electrolysis and those using fossil fuels with carbon capture utilisation and storage (CCUS), although electrolysis projects were responsible for more than 80% of the total drop. These delays and cancellations included early-stage projects across Africa, the Americas, Europe and Australia. At the same time, the number of projects that have received a final investment decision grew by almost 20% since the publication of the Global Hydrogen Review 2024 and now represent 9% of the total project pipeline to 2030.Despite the recalibration of industry plans, low-emissions hydrogen production is expected to grow strongly by 2030. Low-emis...

Global Hydrogen Review 2025 Policies
Highlights Announced public funding for low-emissions hydrogen decreased by nearly two-thirds compared to the Global Hydrogen Review 2024 (GHR-24), to a cumulative USD 38 billion, but a larger share of funds is now making its way to specific projects. Several programmes in the European Union, India, Japan and United Kingdom have progressed to the second phase or beyond, with new calls building on learning from the first phase.Almost 90% of the public funding comes from advanced economies; other policy instruments like land allocation, tax incentives and reduced administrative procedures remain more common among emerging markets. The supply side still receives…

Global Hydrogen Review 2025 Production prospects to 2030
Only a small fraction of the total project pipeline can realistically start operating by 2030, highlighting policy gaps The potential low-emissions hydrogen production from announced projects that could be available by 2030 has declined compared to in Global Hydrogen Review 2024. With only five years to 2030, and taking into account typical development cycles, which stretch from three to six years, realising the full pipeline of projects seems very difficult. In addition, we estimate that half of the announced projects face deferred start dates compared to the commercial operation date announced by developers. Delays are particularly acute among electrolyser projects…

What it would take to unlock the next phase of hydrogen growth
…was met with a vigorous response from the private sector, which spearheaded the announcement of hundreds of low-emissions hydrogen production projects.This created high expectations for what was still a nascent sector. When the IEA published its Global Hydrogen Review 2022, governments had adopted targets that cumulatively accounted for 190 GW of electrolysis capacity by 2030 – even though less than 0.7 GW was operational at the end of 2022 and, according to the latest data available, global capacity was on track to barely surpass 4 GW in 2025.To be sure, setting ambitious goals has proved useful in attracting corporate…

Global Hydrogen Review 2025
…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…

Global Hydrogen Review 2026
…Japan.The conflict in the Middle East is impacting global supplies of hydrogen and hydrogen derivatives, such as fertilisers, exposing vulnerabilities in their supply chains. As energy security concerns move higher up the policy agenda, this year's report considers the potential contributions of low-emissions hydrogen and hydrogen derivatives to enhancing energy security. It takes stock of deployment to date to assess the level of hydrogen uptake that could be achieved by 2030.This sixth edition of the Global Hydrogen Review includes novel analysis on what constitutes an acceptable cost for low-emissions hydrogen across multiple applications and regions…

COP28: Tracking the Energy Outcomes
…tripling global renewable energy capacity and doubling global energy efficiency improvements by 2030, and deploying emerging technologies, such as low-emissions hydrogen and carbon capture.The IEA, in collaboration with the United Nations Framework Convention on Climate Change (UNFCCC) Secretariat, is tracking progress towards the energy objectives established at COP28. This forms part of our broader work, at the request of governments, to support the full and timely implementation of the energy promises made in Dubai by identifying pathways forward and providing policy makers with advice on accelerating national and secure clean energy transitions. The IEA's landmark 2024 report…

Global Hydrogen Review 2026 Policy
A total of USD 41 billion in public funding has been identified in policy updates made since the Global Hydrogen Review 2025 (GHR-25). Nearly two-thirds of this funding is linked to legislation in force and almost 25% has already been disbursed to projects, triggering final investment decisions (FID). As in GHR-25, most of the funding comes from advanced economies and for every dollar going to demand, about 1.5 dollars go to supply.The number of national hydrogen strategies has stabilised at 66 globally, and recent updates have focused either on implementing strategy actions (Brazil, Mauritania, Romania) or revising targets…

Global Hydrogen Review 2026 Investment and innovation
Capital spending on low-emissions hydrogen projects reached nearly USD 7 billion in 2025, nearly double the 2024 level and equal to 0.7% of global investment in energy supply. Investment in electrolysis overtook investment in carbon capture, utilisation and storage (CCUS)-based hydrogen, thanks to a stronger pipeline, higher capital intensity and faster project progress, and could account for around 70% of nearly USD 10 billion in investment in 2026.China and Europe lead committed electrolysis projects, with China accounting for more than 60% of capacity by 2026 and 25% of estimated investment. Europe represents less than 20% of capacity but 45% of…
