BV approved the floating CO2 storage and injection concept from Technip Energies

  Technip's Offshore C-Hub concept is a floating vessel that receives liquid CO2 from shuttle tankers, provides buffering storage for liquid CO2 in its hull, and continuously injects CO2 into an offshore collector or depleted tank.

The solution includes the following key features:

• Process the tops to continuously inject CO2 at the desired pressure and temperature of the geological deposit;
• storage of liquid CO2 packages and reserve volumes in the cargo area;
• unloading of liquid CO2 package from liquid CO2 ships in coastal conditions; a
• Permanent mooring at sea above injection wells, minimization of subsea system.

Its storage volumes can be adapted to the specifics of each project and the associated logistics chain deployed to transport CO2 (e.g. temporary storage capacities can range from 20,000 to 40,000 m3), Technip explains. According to the company, the concept offers a reliable, safe and cost-effective solution for permanent CO2 storage in offshore reservoirs. "We are committed to developing sustainable and innovative solutions, including carbon capture and storage (CCUS) solutions, to decarbonize industry and support zero carbon goals," Technip Energies said in a social media update. The French firm, along with deepC Store and Mitsui OSK Lines (MOL), is developing a floating carbon capture and storage (CCS) center described as “the first large-scale offshore multi-user center" in the Asia-Pacific region.
