Expectations for annual clean hydrogen production by 2030 are shrinking, for the first time. As of 2025, about a million metric tons of low-emissions hydrogen are produced annually. That’s less than 1% of total hydrogen production. In last year’s Global Hydrogen Report, the IEA projected that global production of low-emissions hydrogen would grow to as high as 49 million metric tons annually by 2030. In the 2025 edition, though, the IEA’s production prediction had shrunk to 37 million metric tons annually by 2030.
