Global production of green hydrogen has started to surge, driven mainly by major policy initiatives in North America, UK-based international data analytics and consultancy group GlobalData has reported.
Current Production Status
Production of low-carbon hydrogen in general has been largely flat, or grown only slowly, for years. But acceleration started a couple of years ago.
Global production of all forms of low-carbon hydrogen had reached 0.84 million tons a year in 2024. Total global low-carbon production capacity in that year had amounted to 1.7 million tons a year. The consultancy forecast, in its 'Low-Carbon Hydrogen Market Report, Update 2025 — Global Market Outlook, Trends, and Key Country Analysis', that, by 2030, global low-carbon hydrogen production would hit 42 million tons a year in the low case scenario, or 65.3 million tons a year in the high case scenario.
Types of Low-Carbon Hydrogen
Low-carbon hydrogen is subdivided into green hydrogen, blue hydrogen, purple hydrogen and turquoise hydrogen:
Green hydrogen: Produced by the electrolysis of water, using renewable energy (note that hydrogen produced using specifically solar power can also be called yellow hydrogen).
Blue hydrogen: Comes from natural gas by means of steam methane reforming or autothermal reforming, coupled with carbon capture and storage.
Purple hydrogen: Also called pink hydrogen or red hydrogen, produced by the electrolysis of water using nuclear energy.
Turquoise hydrogen: Not yet proven at scale, uses methane pyrolysis to produce hydrogen and solid carbon.
Market Share Transformation
Green hydrogen had accounted for 14.9% of global low-carbon hydrogen production in 2024. Blue hydrogen had been responsible for 76.3%, purple hydrogen for 0.3%, and turquoise hydrogen for 0.1%. Other types of production had accounted for the remaining 8.4%.
But in 2030, GlobalData predicted, green hydrogen will account for 88.6% of global low-carbon hydrogen production. Blue hydrogen's contribution will fall to 11.3%, while purple and turquoise hydrogen will contribute a steady 0.1% each.
North America Leads the Transformation
North America is key to this transformation.
"The hydrogen market in the Americas has grown significantly over the last few decades, owing to federal and state-level initiatives in the U.S., significant efforts in Canada, and emerging policies in Mexico," explained GlobalData power analyst Attaurrahman Ojindaram Saibasan. "Each country in the region has approached hydrogen development with varying levels of ambition and strategy, resulting in a dynamic and rapidly evolving market."
United States Policy Framework
In the U.S., the federal government launched low-carbon hydrogen initiatives in the early 2000s, and followed up with further moves to stimulate its production in 2005, 2009, 2021 and 2022. A number of U.S. states, especially California, Massachusetts and New York, have also launched their own initiatives.
Canada's Provincial Approach
"Canada's approach is characterized by strong federal leadership complemented by active provincial initiatives," he reported. "Provinces such as British Columbia, Quebec, and Ontario are at the forefront of Canada's hydrogen efforts. Each province is using its distinct regional advantages — such as British Columbia's access to renewable energy or Quebec's hydroelectric capacity — to drive hydrogen development. These provincial strategies are aligned with the national vision while also catering to local economic and environmental priorities, enabling a decentralized yet cohesive approach to hydrogen adoption."
Mexico's Emerging Strategy
As for Mexico, that country's low-carbon hydrogen production policy is still in an early development stage. But the country is investigating the potential of the industry, especially regarding its ability to exploit the country's resources and location to both produce and export hydrogen.
Challenges Ahead
"Though low-carbon hydrogen production is likely to witness rapid growth in the coming years, it will require scaling up to reduce costs, replacing high-carbon hydrogen with low-carbon hydrogen in current applications, and expanding the use of hydrogen to new applications," cautioned Saibasan.
Key Projections Summary
2024 production: 0.84 million tons per year
2024 capacity: 1.7 million tons per year
2030 production forecast: 42-65.3 million tons per year
Green hydrogen share 2024: 14.9%
Green hydrogen share 2030: 88.6%
Blue hydrogen share 2024: 76.3%
Blue hydrogen share 2030: 11.3%
A Dramatic Six-Year Shift
This represents a dramatic shift from blue to green hydrogen dominance within six years, driven primarily by policy support in North America and falling renewable energy costs enabling competitive green hydrogen production. By 2030, green hydrogen will surge from less than 15% to account for nearly 90% of global low-carbon hydrogen production, representing one of the most significant structural transformations in the global energy transition.
