(Berlin) - Berliner Now GmbH has published an approval guide for hydrogen filling stations. It was created, as it is said, “in collaboration with authorities and industry partners”. 
Target groups include investors, authorities, monitoring organizations and all those involved in the construction and operation of a “Hydrogen Refueling Station” (HRS) for road vehicles. The guide names types of filling stations, shows approval processes and approval processes for a hydrogen filling system. In Germany, the HRS infrastructure currently consists of compressed gaseous hydrogen (CGH2) systems. According to the guidelines, a pressure level of 700 bar is primarily preferred for passenger cars with fuel cell systems. For commercial vehicles, buses and trucks that can carry a larger tank, storage and refueling with a pressure of 350 bar has initially become established. Both types of refueling are not compatible due to the different pressure levels. There are currently no public tank systems for liquefied hydrogen (liquefied, LH2) or crypto-compressed hydrogen (CcH2) in this country.
Checklists and process flows
Around a dozen people, offices and institutions are involved in the approval process, from property managers, owners, appraisers, trade inspectors and architects to the fire department. The approval process is explained, there are also checklists of common documents and reports, information on relevant institutions and the approval process as a diagram.
However, according to the information, this is expressly not a set of rules, but the guide is intended solely to provide guidance on the procedure.
