Dunkirk's intended LNG terminal would have an annual hosting capacity of 9 Gm3 (billions of m3), or around 20% of France's current consumption. It would have the following facilities :
- a berthing station which would host around 80 LNG tankers per year with a capacity of up to 270,000 m3,
- an LNG unloading system,
- two or even three LNG storage tanks each with a capacity of 190,000 m3; a tank measures around 50 m in height and has a diameter of 90 m ;
- a regasification unit ;
- a seawater inlet to reheat the LNG: for the Dunkirk project, some of the hot water from the Gravelines plant would be used to heat the LNG ;
- a connection to the distribution network.
Tax revenues generated by the terminal could reach an annual €20 m. It would raise sea traffic from 4 to 5 MT per year, namely, €6 m per year in turnover.
The project represents a €700 m investment for EDF and between €50 and 70 m for the Autonomous port of Dunkirk.
