H2 pipeline Legden-Marl-Scholven

SYNEQT (Evonik)

SYNEQT's pipeline system connects the Marl Chemical Park and the Scholven refinery in North Rhine-Westphalia with the hydrogen core network. The total route comprises more than 50 kilometers of operational pipeline, 41 kilometers of which were converted from an existing natural gas pipeline to hydrogen, 13 kilometers were newly constructed. In addition, new sections were built, including a three-kilometer pipeline through the Marl Chemical Park and a ten-kilometer connection to the refinery in Gelsenkirchen-Scholven. The system enables the transport of up to 50,000 tons of hydrogen per year and brings climate-neutral hydrogen directly to industrial customers.

The project is part of the GET H2 Nukleus initiative and was implemented by SYNEQT together with partners from the hydrogen value chain. The aim is to connect the climate-neutral production of green hydrogen in northern Germany with industrial customers in North Rhine-Westphalia and Lower Saxony.

SYNEQT completed work on the entire pipeline route from Legden via Marl to Gelsenkirchen-Scholven in just under two years of intensive project work. Six stations were included in the conversion. The pipeline strengthens the role of the Marl Chemical Park as a hydrogen hub."
