DHUNE

DHUNE is a hydrogen infrastructure project in the Dunkirk industrial zone project which will connect up the low-carbon hydrogen production and consumption projects in this area. It will thus contribute to foster the development of decarbonisation solutions in an industrial-port zone with high greenhouse-gas emissions that account for 20% of industrial CO₂ emissions in France.

This project was financed by the State as part of France 2030 operated by ADEME:

The main purpose will be industrial use with the replacement of coke and natural gas with renewable or low-carbon hydrogen. Heavy mobility is one of the additional use options being considered, on roads and waterways.

Premières étapes

• Q4 2022: Call for interest for the hydrogen grid project.
• Early 2023: Feasibility study launched after the success of the call for interest.
• Early 2024: launch of basic studies (FEED).

Next stages

• 2024 : Prior consultation of the project.
• Half 2025 : End of basic studies, planned investment decision (FID)
• Fin 2027 :  Scheduled date of 1st commissioning.

• Length: approximately 10 km.
• Transport capacity: approximately 20 GWh/d.
• The equivalent of 1 GW of installed or imported electrolysis power could be developed.

According to an initial assessment, this project could contribute to averting 11.1 Mt CO₂eq/year in emissions.
