Ruhr metropolis: hydrogen, water and digital cooperation
Editorial update: 8 November 2026. Selected relationships supported by original sources; not a complete market directory.
What distinguishes the Ruhr metropolis
This report defines the region as the Regionalverband Ruhr territory: eleven independent cities and four districts, comprising 53 municipalities. Essen is one of those cities. This multi-city structure makes cooperation across municipal boundaries a distinct subject of the report.
Ruhr metropolis: hydrogen and regional coordination
Business Metropole Ruhr describes Hydrogen Metropole Ruhr (HyMR) as a network for companies, research and policy, including project support and connections between stakeholders. This regional context helps interpret industrial and infrastructure proposals. The source is the regional economic development organisation; its ambitions do not establish existing supply or measured climate benefits.
Industry and hydrogen: the DoHa pipeline
The planned DoHa hydrogen pipeline connects Dorsten with Duisburg-Hamborn. OGE identifies OGE and Thyssengas as project partners and supply to thyssenkrupp Steel Europe’s steel production as one intended use. According to OGE, construction of the first section in the Münster administrative district began in March 2026. The section in the Düsseldorf administrative district is undergoing planning approval; commissioning is planned for 2027.
Status: individual sections under construction or undergoing approval. The developer’s project page does not establish that hydrogen is already available at arbitrary industrial sites.
Water: supply areas crossing city boundaries
Gelsenwasser’s supply overview lists Gelsenkirchen, Haltern am See and Marl among the municipalities it supplies directly. Its legal notice gives a Gelsenkirchen address. This establishes a supply relationship linking several Ruhr municipalities. Gelsenwasser’s wider supply area also extends beyond the Ruhr metropolis and does not coincide with the RVR territory.

DigitalRegion.Ruhr: shared data and exchange of experience
The RVR describes DIGITALREGION.RUHR as a coordination point for municipal digital development. Open Data Ruhr brings open administrative data together on a regional platform; CONNECTED.RUHR supports exchange between departments responsible for smart cities. These are documented forms of intermunicipal cooperation. They do not imply a uniform IT architecture or joint procurement by all municipalities.
Local detail: Essen
The Essen city report examines municipal heat planning and the historical Dürerschule LoRaWAN case. These are local applications that cannot be assumed to extend to all 53 municipalities.

Messe Essen’s official calendar lists 16–18 February 2027, Essen as the venue, and con|energy and MESSE ESSEN as organisers. The exhibition is for trade visitors. An exhibitor profile does not establish headquarters, a customer contract or network operation in Essen.

Questions for a specific project
Is the site within the relevant network or study area? Who is responsible for planning, construction and operation? Is the project approved, under assessment or already available? Which interfaces and data rights are required for buildings, metering and energy management? The sources establish the stated roles and planning stages, rather than general provider quality.
