Nuclear hydrogen production could dramatically reduce carbon emissions as demand rises globally. The majority of the hydrogen used presently is produced from fossil fuels, which results in carbon dioxide emissions. Nuclear energy has the potential to replace fossil fuels for supplying a forecasted large increase in the demand of hydrogen with low or zero carbon emissions. There are currently several demonstration projects worldwide ongoing and planned for the production of hydrogen using operational nuclear power plants, as well as developments considering advanced reactor technologies for hydrogen production. The Coordinated Research Project ""Assessing Technical and Economic Aspects of Nuclear Hydrogen Production for Near-term Deployment"" addressed relevant facets for the potential upscaling of nuclear hydrogen production technologies, based on the specific cases of participant Member States. This publication is intended for scientists and specialists, as well as various stakeholders interested in hydrogen production using nuclear energy.
