Project TN02000007 National Hydrogen Mobility Center is co-financed with state support from the Technology Agency of the Czech Republic under the National Competence Centers Program. This project is also financed under the National Recovery Plan from the European Recovery and Resilience Facility.

The National Hydrogen Mobility Center – NAHYC-m is a center that was established as part of the implementation of the Hydrogen Strategy for a Climate-Neutral Europe and the Hydrogen Strategy of the Czech Republic, which reflects the goal of the European Green Deal – to achieve climate neutrality by 2050. The center focuses on R&D cooperation between key players in the Czech Republic – the state, research organizations, and companies in the field of hydrogen technologies – and is based on the principles of integral ecology. The Transport Research Centre (CDV) was commissioned to establish the centre, which currently consists of 14 other companies: EGÚ Brno, a.s., ORLEN UniCRE a.s, the University of West Bohemia in Pilsen, the Technical University of Ostrava, ] Brno University of Technology, DEVINN s.r.o., Czech Hydrogen Technology Platform z.s., Adast Systems, a.s., GREEN REMEDY, s.r.o., APT, spol. s r.o., Czech Technical University in Prague, ZEBRA GROUP s.r.o., SAKO Brno, a.s. and TATSUNO EUROPE a. s.

The aim of the sub-project is to create tools for the conceptual development of hydrogen mobility so that its controlled development, which is in the interest of society as a whole and has many benefits, can take place. Another objective of the sub-project is to create a set of tools for state administration bodies, in particular the Ministry of Industry and Trade (MPO), the Ministry of Transport (MD), and the Ministry of the Environment (MŽP), enabling the effective and conceptual development of hydrogen mobility, especially with regard to the use of low-emission hydrogen. In the context of the sub-project, the hydrogen economy in transport in the Czech Republic is seen as a tool for fulfilling the Czech Republic’s commitments to reduce CO2 emissions and, in the long term, as a tool for reducing dependence on foreign energy sources in the Czech transport sector.

The aim of the sub-project is to create support tools for the Center’s strategic research agenda and to expand activities to include new requirements from the Ministry of Industry and Trade and the Ministry of Transport in the area of hydrogen mobility implementation, including providing research support documentation for updating the NAP ČM. Furthermore, the aim of the sub-project is to create a set of support tools for state administration bodies, in particular the Ministry of Industry and Trade (MPO), the Ministry of Transport (MD), and the Ministry of the Environment (MŽP), enabling the effective and conceptual development of hydrogen mobility, especially with regard to the use of low-emission hydrogen.

The sub-project focuses on selected aspects of hydrogen filling station operation, from changes in hydrogen states during flow through hydrogen systems, through safety issues, to the degradation of materials in contact with hydrogen. The scientific and research activities of the sub-project are divided into three work packages. The first work package focuses on safety issues, predicting hydrogen leakage, hydrogen detection at filling stations, and safety measures. The second work package includes research activities focused on changes in the state of hydrogen in hydrogen systems, including the issues of filling and emptying hydrogen storage tanks and the associated energy and economic demands and heat dissipation. The third work package focuses on the degradation of materials during long-term contact with hydrogen. This package will also explore the possibilities of using additive technologies (3D printing) in the manufacture of hydrogen equipment components. The results of the sub-project are or will be as follows:

• Documentation for the approval process concerning the safety of hydrogen filling stations

The aim of the project is to research and develop high-pressure hydrogen sampling equipment for the entire hydrogen economy ecosystem, from production to filling station nozzles. The required purity of hydrogen is defined by the ČSN ISO 14687 standard. Sampling from filling stations is made difficult by the high pressure and the required high chemical purity of hydrogen. Sampling therefore requires sampling equipment that is not currently available in Czech production. Appropriate preparation of the sampling equipment is also necessary for sampling. The aim of the sub-project is to create the conditions and equipment for accelerating the introduction of hydrogen infrastructure elements for mobility. The sub-project consists of three work packages. WP1 deals with research into the technology of the equipment. WP2 deals with the design and verification of sampling equipment (verified technical equipment – functional sample, ready for prototype implementation/industrial-legal protection of the equipment in the form of a utility model, possibility of selling a license). WP3 deals with and verifies equipment for preparing sample containers for hydrogen fuel sampling (method of preparing sampling equipment). The results of the sub-project are or will be as follows:

• High-pressure hydrogen sampling device (functional prototype)
• Device for preparing sample containers for hydrogen fuel sampling (functional prototype)
