IN Brief:
- H2Coastlink 1 comprises approximately 24km of DN400 high-pressure hydrogen pipeline.
- Preparatory work is due to begin in summer 2026, with handover planned for autumn 2027.
- The route includes around 90 crossings requiring trenchless and other specialist construction methods.
Friedrich Vorwerk Group has secured a major contract through a joint venture to construct the H2Coastlink 1 hydrogen pipeline between Emden and Leer in north-west Germany.
EWE Netz awarded the contract while acting as general contractor for project promoter and transmission system operator GTG Nord. Its value has been described as a double-digit-million-euro amount.
H2Coastlink 1 will comprise approximately 24km of DN400 high-pressure pipeline, together with a connecting line from a future electrolyser to the hydrogen injection facility in Emden and links into wider infrastructure around Leer.
Preparatory work is scheduled to begin during summer 2026, with the completed pipeline due to be handed over for operation in autumn 2027.
The route will connect EWE’s planned 320MW hydrogen-production plant at Emden-Borssum with Leer-Nord, where the project is intended to interface with Gasunie’s HyPerLink infrastructure and the GTG Nord transmission network.
Approximately 90 transport, water, ecological, and other crossings must be negotiated during construction. Several will be installed below existing features through horizontal directional drilling and related trenchless methods, reducing open excavation across operational or environmentally sensitive areas.
Alongside route construction, the works will require welding, inspection, corrosion protection, pressure testing, reinstatement, environmental controls, logistics, and coordination with landowners and authorities. Hydrogen service places additional emphasis on material selection, joint quality, testing, and long-term integrity.
The pipeline forms part of Germany’s planned hydrogen core network, which is intended to create approximately 9,000km of connected transmission infrastructure. The national programme combines converted natural-gas assets with new pipelines linking production, import, storage, and industrial demand.
H2Coastlink 1 has received support through the Important Projects of Common European Interest programme, backed by the German federal government and Lower Saxony.
Hydrogen plans enter physical delivery
European hydrogen development has spent several years advancing through feasibility work, funding decisions, and production announcements. Pipeline awards show parts of the market moving into construction, although demand, electricity costs, and production economics remain uneven.
A large electrolyser cannot operate as an isolated asset where customers are spread across industrial regions. Connection infrastructure allows hydrogen to reach refineries, chemical plants, steelmaking, dispatchable generation, transport hubs, and storage facilities without relying solely on road transport.
Production and pipeline programmes must progress in sequence because a completed network with limited supply may be underused, while an electrolyser without a transport route faces restricted access to customers. Funders and network operators are coordinating projects developed under different approval, financing, and construction timetables.
Germany is also reshaping its electricity system around greater renewable output and additional controllable generation, with proposed capacity procurement creating a route for hydrogen-ready power generation. Pipeline development and electricity-system reliability are consequently becoming more closely connected.
For contractors, the emerging network draws heavily on established gas-infrastructure capabilities while introducing more demanding assumptions around hydrogen compatibility and leakage. Route development, welding, non-destructive testing, trenchless installation, compressor systems, and commissioning remain relevant, although materials and procedures require specific validation.
Horizontal directional drilling will be particularly important where the route intersects roads, railways, waterways, and protected land. The method reduces surface disruption but requires detailed ground investigation, drilling-fluid management, bore-path control, and contingencies for difficult geology.
Construction logistics must also account for long pipe sections, welding spreads, temporary access, topsoil management, and reinstatement across agricultural or environmentally sensitive areas. Seasonal restrictions and ecological commitments may narrow available working periods.
The contract gives Friedrich Vorwerk a further role in converting European energy policy into constructed assets. Its value is substantial, but the pipeline remains one part of a network requiring continued investment in production, storage, compression, metering, transmission, and user connections.
Operational handover in autumn 2027 will depend on the route, crossings, testing, and connected facilities progressing together. H2Coastlink 1 will provide a physical link between the planned Emden electrolyser and regional infrastructure, placing engineering and construction at the centre of Germany’s hydrogen programme.
