KML: Air Liquide hydrogen network

Air Liquide's private hydrogen network in the Rhine-Ruhr region, which was founded in 1938, runs from Castrop-Rauxel via Marl, Oberhausen, Duisburg, Krefeld, Leverkusen, Dormagen and Düsseldorf to other cities. The network has a total length of 200 kilometres. The course of the Air Liquide hydrogen network is only shown schematically on H2Land NRW and does not correspond to the actual course of the pipelines.
