Released in September 2025, the International Energy Agency’s Global Hydrogen Review provides a comprehensive analysis of the hydrogen sector's progress, challenges, and outlook.
Key Insights:
Global Hydrogen Demand: Increased to nearly 100 million tonnes (Mt) in 2024, driven by traditional industrial applications such as refining and chemicals. Demand from emerging sectors remains below 1% of the total.
Low-Emissions Hydrogen Production: Grew by 10% in 2024, reaching approximately 1 Mt. Despite this growth, it still accounts for less than 1% of global hydrogen production.
Project Pipeline Trends: The projected low-emissions hydrogen production by 2030 has declined to 37 Mt per annum, down from 49 Mt in the previous year, due to project delays and cancellations.
Electrolyser Capacity: Global installed electrolyser capacity reached 2 gigawatts (GW) in 2024, with China accounting for 65% of this capacity.
Cost Competitiveness: The cost gap between low-emissions hydrogen and unabated fossil-based production remains significant, though it is expected to narrow by 2030, particularly in regions with favorable renewable resources and supportive policies.
Southeast Asia's Role: The region's hydrogen demand reached 4 Mt in 2024, nearly 4% of the global total, with Indonesia, Malaysia, and Vietnam being the largest contributors.
