Hydrogen for mobility is produced by electrolysis. In this process, water is split into its components O2 (oxygen) and H2 (hydrogen) using electricity.
Empa launched Switzerland's first 350 and 700 bar hydrogen filling station in October 2016, doing pioneering work particularly concerning system integration, design, operational safety, and licensing in all 26 cantons. To create more clarity for implementation, Empa worked together with the authorities involved in the approval process to draw up guidelines for the construction of hydrogen filling stations, thus paving the way for the rapid development of a nationwide fueling infrastructure.
Currently (as of summer 2020), around 30 customers with fuel cell vehicles regularly refuel at Empa. Among them are vehicles of a cab fleet and the Zurich cantonal police force.
