According to the International Energy Agency (IEA), global hydrogen demand reached almost 100 million tons (Mt) in 2024, a 2% increase compared to 2023.
This increase was driven by rising usage in sectors traditionally employing hydrogen as a raw material: oil refining, the chemical industry, and the steel industry.
Meanwhile, hydrogen consumption for new applications, such as electricity production and low-emission fuels, remains low.
"Demand for hydrogen in new applications accounts for less than 1% of total global demand and is almost entirely concentrated in biofuel production," the IEA wrote in Global Hydrogen Review 2025 report.
In 2024, China was the largest consumer of hydrogen, accounting for 29% of total global demand.
The next largest hydrogen consumers were North America (16%), the Middle East (15%), and India (10%).
Hydrogen consumption in these regions increased compared to 2023, particularly in the Middle East (6% growth) and India (4% growth).
"This is largely due to increased use in oil refining and chemical production, as well as steel production in the case of India," said the IEA.
The majority of global hydrogen supply is produced using high-emission fossil fuels, namely 290 billion cubic meters (bcm) of natural gas and 90 million tons of coal equivalent (Mtce) in 2024.
Low-emission hydrogen, produced using renewable energy, nuclear power, or carbon capture, utilization, and storage (CCUS) technology, remains limited.
"Low-emission hydrogen production increased by 10% in 2024 and is projected to reach 1 Mt in 2025. However, its share remains less than 1% of global production," said the IEA.
