This module focuses on hydrogen filling stations. The main objective of the module is to introduce the reader to the basic issues of design, construction and operation of filling stations. The introductory part introduces the reader to the history and development of hydrogen filling stations and their use in transport. Information is provided on the first hydrogen filling stations and their subsequent development. Basic information on hydrogen is also provided in this chapter, but only in the form of a basic overview. In the following sections this information is supplemented by a basic overview of the legislative requirements for the design and operation of hydrogen filling stations. This section also introduces the reader to a basic overview of the standards that affect the construction and operation of filling stations. The next chapter summarizes information on industrial gas filling stations and, in passing, on the production of hydrogen and its transport to the filling site. These issues are covered in depth in modules that focus on them. Other chapters deal with the division of filling stations, their construction, individual structural units and operational safety. Therefore, cases of accidents that have occurred during the operation of filling stations are also presented. The safety of operation not only of filling stations, but of hydrogen technology in general, is crucial for its future development and practical use. The last chapter is devoted to forecasts for the future development of refuelling stations and their use in transport.
