H2, CO₂, CCUS: turnkey solutions for your low-carbon projects

With carbon-free molecules, the scope of our operations is expanding. Entrepose Contracting is not limited to storage alone, but focuses on comprehensive terminal infrastructure, covering processing, liquefaction, packaging, storage and dispatch.

Our teams develop and integrate solutions for hydrogen, CO₂, ammonia and other emerging energy carriers, combining cryogenic or high-pressure equipment, compression, cooling, purification and liquefaction units, terminals, and distribution or shipping interfaces.
This capability enables us to support projects at an earlier stage than in LNG, with a bespoke, turnkey approach tailored to the new decarbonisation value chains.
