About the Project

WAL – Wasserstoff aus Lubmin is a large-scale green hydrogen project developed by H2APEX and Copenhagen Infrastructure Partners (CIP). It aims to produce renewable hydrogen to support the decarbonisation of industry and energy systems in Germany and Europe.
The project develops a hydrogen production facility based on electrolysis and a substation, powered by renewable electricity, with an initial capacity of around 100 MW and potential expansion in later phases.
The facility will be located in Lubmin on the German Baltic Sea coast, a site with direct access to renewable energy, grid infrastructure, and the hydrogen core network.
The project is currently in development, with permitting processes ongoing and key commercial and technical agreements under preparation or negotiation.
The project targets final investment decision (FID) around 2027 and start of operations (COD) in 2029.

Hydrogen & Technology

Green hydrogen is hydrogen produced using renewable energy sources such as wind or solar power, resulting in minimal greenhouse gas emissions.
Hydrogen is produced via electrolysis, where water is split into hydrogen and oxygen using electricity from renewable sources.
Hydrogen is used in industries such as steel, chemicals, and refining, as well as in energy storage and heavy transport.

Environmental & Sustainability

Green hydrogen can significantly reduce CO₂ emissions by replacing fossil fuels in hard-to-abate sectors.
The WAL project supports European and German climate goals by enabling low-carbon industrial processes and contributing to decarbonised energy systems.
Yes, water is required for electrolysis. The project includes a dedicated water supply concept to ensure sustainable sourcing. 

A key focus of the project is the sustainable use of water. Instead of relying on scarce freshwater resources, treated water from a local wastewater treatment plant is used as a feedstock. This “treated effluent” undergoes an innovative, multi-stage purification process, in which it is further cleaned and processed to produce ultrapure water with no remaining minerals. Technologies such as ultrafiltration and reverse osmosis are applied in this process.

The resulting ultrapure water can then be used for hydrogen production, eliminating the need for drinking water, groundwater, or surface water. 

The process wastewater remaining after treatment, now enriched with minerals, is discharged—like the treated effluent from the wastewater plant—into the nearby industrial port. This process wastewater not only complies with all regulatory limits applicable to treated wastewater from the local treatment plant, but, due to the multi-stage purification process, has had additional pollutants removed that would otherwise enter the environment.

Domestic wastewater from sanitary facilities is handled separately and discharged, as usual, into the local wastewater treatment plant. In the event of an incident involving contaminated water, technical containment systems are in place to ensure that such wastewater does not enter the environment and can be disposed of safely and properly.

As with any industrial project, impacts may include land use and resource consumption. These are assessed and managed through environmental permitting processes.
The project is designed to minimize emissions during production by using renewable electricity and adhering to strict regulatory standards.

Safety

Yes. Hydrogen has been safely used in industry for decades. Its handling is well understood and supported by robust safety standards.
The project follows stringent engineering standards, monitoring systems, and operational procedures to ensure safe production, storage, and handling.
Hydrogen projects in Germany are subject to strict regulatory frameworks, including environmental and industrial permitting (e.g. BImSchG).

Local Impact

The project strengthens the Lubmin region as a key energy hub and supports the transition towards a sustainable energy system.
Yes. The project is expected to create jobs during construction and operation, as well as indirect employment in related industries.
Temporary impacts may occur during construction. These are managed through planning and coordination with local authorities.
Stakeholders are engaged through permitting processes, consultations, and ongoing communication.

Infrastructure & Operations

Hydrogen will be transported via the German hydrogen core network, including connections to the FLOW corridor starting in Lubmin.
Key infrastructure includes the electrolysis plant, grid connection, substations, water supply systems, and pipeline connections.
The project integrates renewable power supply, electricity grid access, and hydrogen transport infrastructure into a single site.

General Energy Transition

Hydrogen enables the decarbonisation of sectors that cannot easily be electrified, such as heavy industry and long-distance transport.
Key challenges include market development, infrastructure rollout, and regulatory frameworks.
Hydrogen complements electrification by providing storage, flexibility, and decarbonisation options for hard-to-abate sectors.

Funding

The project is jointly developed by H2APEX and CIP and supported by public funding mechanisms such as IPCEI, reflecting its strategic role in Europe’s energy transition.
