Two interactive data tools developed by the International Energy Agency allow users to explore developments related to low-emissions hydrogen projects worldwide.

An interactive map of low-emissions hydrogen production projects provides data on almost 2,000 projects that are either already in operation or have been announced. Most projects to date are concentrated in Europe and Australia, but a growing number are planned in Africa, China, India, Latin America and the U.S.

An estimated 444 GW of green hydrogen projects – based on renewable energy sources — are scheduled to come online by 2030. The project pipeline for both blue — based on fossil fuel and carbon capture and storage technology — and green hydrogen is dominated by green hydrogen, which accounts for 82% of total hydrogen production by the end of the decade, far exceeding the 17% for blue hydrogen.

Another interactive tool enables assessment of the levelized cost of hydrogen production from solar photovoltaics and onshore wind in different locations worldwide. Cost-optimal capacities for solar, wind and electrolyzers are displayed. The data indicate that the world’s cheapest renewable hydrogen could be produced in hybrid wind and solar-powered electrolyzers in the U.K., Norway, eastern Canada and southern Argentina.
