(Cologne) – Climate-neutral gases such as green hydrogen or synthetic methane can be produced using power-to-gas technologies and transported via the existing gas infrastructure. An interdisciplinary team of experts has developed a guide that offers support during commissioning. According to the authors, the approval processes are complex, “sometimes confusing” and present system operators with “big challenges”.
The compendium, which is several hundred pages long, is divided into an approval guide and a technical guide. The first part highlights the current situation of the approval process and offers decision-making aids when choosing which procedures to use. It explains how an approval process works depending on the type of system and which documents the future operator must create and submit.
In contrast, the technical guide explains which laws, regulations and rules apply from planning to operation of the system. The focus is on the requirements for system operators and manufacturers. Both parts of the guide take into account special features due to the connection to different areas of use. This includes feeding hydrogen or methane from power-to-gas systems into the existing gas network, connecting to hydrogen filling stations, converting electricity back into electricity and supplying industrial plants with hydrogen.
Guide is part of the DVGW regulations
The elaborations were funded by the Federal Ministry of Economics as part of the 36-month “Portal Green” project. The project team consists of the Gesellschaft für Anlagen- und Reaktorsicherheit gGmbH (GRS) as consortium leader, the German Gas and Water Association DVGW eV, DBI Gas- und Umwelttechnik GmbH, the Bergische Universität Wuppertal and Uniper SE. “Portal Green” was completed on schedule. The guidelines are regularly updated as part of the DVGW regulations.
