The application of hydrogen energy in the railway sector should be technologically developed though pilot projects and tests. The International Union of Railways (UIC) implements projects and activities: UIC IR Project H2TR ‘Hydrogen technology on railways’: training for the application of technical standards; safety requirements (vehicles and infrastructure); authority; train performance; refuelling facilities and hydrogen logistic; business case and financing; operational phase. The global development of technology includes the production of hydrogen and all necessary components, as well as intermodal transport. Hydrogen can be used as: drive energy for sustainable mobility; raw material for industry; medium for producing heat; and electricity for heating; energy storage; costs; price; technological readiness; reliability; security can significantly depend on development in other sectors. Due to the existence of opportunities for the application of a clean and healthy energy, SEE countries are developing various strategies and interstate studies.
