The database is subject to the IEA’s Terms and Conditions, available at https://www.iea.org/terms. The IEA produced this dataset as part of efforts to track advances in low-carbon hydrogen technology. It covers all projects commissioned worldwide since 2000 to produce hydrogen for energy or climate-change-mitigation purposes. It includes projects which their objective is either to reduce emissions associated with producing hydrogen for existing applications, or to use hydrogen as an energy carrier or industrial feedstock in new applications that have the potential to be a low-carbon technology. Projects in planning or construction are also covered.
