First planning for a hydrogen network in Siegen

Siegener Versorgungsbetriebe GmbH (SVB), the drinking water and natural gas distribution network operator in the tri-border region of North Rhine-Westphalia, Rhineland-Palatinate and Hesse, is planning to build a 12-kilometre hydrogen pipeline between the Siegen districts of Eiserfeld and Geisweid in 2030 to supply the industrial location of Siegen with hydrogen.

At the same time, the SVB have already started planning the heat supply for the city of Siegen, which has a population of around 100,000. The conversion of the heat supply for the citizens depends to a large extent on which heat sources will be available. One such reliable heat source can be the waste heat from hydrogen production as well as from industrial hydrogen use. By coupling the hydrogen pipeline and the substations by means of electrolysers, the hydrogen can be produced locally, depending on the future capacity in the power grid.

Since Siegen is the intersection of several long-distance gas pipelines, the company is additionally striving to connect to the nationwide hydrogen core network in the medium to long term by rededicating an existing long-distance gas pipeline for the transport of hydrogen.
