Hydrogen core network: terranets bw implements central supply artery for hydrogen in Baden-Württemberg

With the approval of the Federal Network Agency (BNetzA) on October 22, 2024, the construction of the nationwide hydrogen core network will begin. The core network marks an important first step in the development of a hydrogen supply. A network covering around 9,000 kilometers is to be created by 2032. The core network includes further transport pipelines in Baden-Württemberg covering the eastern Swabian Alb, Upper Swabia, the eastern Lake Constance region, the Upper Rhine, Breisgau and the Mannheim/Karlsruhe region. The South German Natural Gas Pipeline (SEL) will be the central supply artery for hydrogen in Baden-Württemberg. Further expansion will take place as part of the integrated network development planning for gas and hydrogen.

Flow - making hydrogren happen. The pipeline for hydrogen stretching from northeast to southwest.

With the "making hydrogen happen” project, the so-called Flow project, GASCADE, ONTRAS and terranets bw are planning a high-performance pipeline system for green hydrogen. Existing infrastructure will be used to connect international hydrogen markets with industrial customers in Europe. First pipeline sections could be converted as early as 2025 already, thus providing a significant building block in the European hydrogen ramp-up and the energy transition.

Cross-border transport of hydrogen: RHYn Interco connects France and Baden-Württemberg from 2028.

Together with the French gas infrastructure operator GRTgaz and the distribution system operator bnNETZE, terranets bw is working on a cross-border transmission system for hydrogen. From 2028, the Upper Rhine region should thus gain access to the first H₂ grid in Baden-Württemberg, which will transport hydrogen to 100 %.

Demand surveys for an efficient hydrogen infrastructure

Information on the development of generation and consumption hubs is essential for the design of efficient energy networks. From February 7 to March 22, 2024, two national surveys were conducted to determine demand and generation capacities, which will be incorporated into the Germany-wide, integrated planning of electricity and gas networks (CH₄ and H₂). The aim: to build a sustainable hydrogen infrastructure.
