This dataset covers all projects commissioned worldwide since 2000 for the production of hydrogen for energy or climate change mitigation purposes, i.e. their objective is either to reduce the emissions associated with the production of hydrogen for existing applications, or the introduction of hydrogen as an energy carrier or industrial feedstock in new applications where it is not currently widely used, and has the potential to be a low-emissions technology option. Projects in planning or under construction are also included.
Projects are categorised by the production technology (electrolysis; fossil fuels with carbon capture, utilisation and storage; other technologies), the hydrogen-based fuel produced (hydrogen, methanol, ammonia, methane, synthetic hydrocarbons) and the use of the fuel produced.
