Gasunie and Petrogas Transportation B.V. plan to investigate repurposing the Petrogas pipeline under the North Sea for transporting green hydrogen as part of the Demo 1 project. This initiative aligns with the Netherlands' goals of scaling up offshore wind to enhance sustainability and energy independence. Offshore hydrogen networks are seen as crucial for efficiently harnessing wind energy, minimizing infrastructure requirements, and enabling cost-effective energy systems. Gasunie's role in developing a hydrogen network in the North Sea involves evaluating the reuse of existing gas infrastructure, including offshore pipelines. Collaborating with various stakeholders, Gasunie focuses on technical, legal, economic, and environmental aspects of repurposing, emphasizing safety and adherence to the latest standards. The company's experience in onshore hydrogen transmission contributes to its efforts in ensuring safe offshore pipeline reuse. Gasunie's broader vision includes promoting renewable gases like hydrogen and green gas to support the transition to a CO2 neutral energy supply. Through its network spanning the Netherlands and Germany, Gasunie plays a key role in facilitating gas transport, storage, and trading, while actively engaging in energy innovation to drive the energy transition forward.
