Carbon Capture, Utilization, and Storage (CCUS)

Your Technical Advisor on CCUS


As the leader in offshore and gas carrier classification globally, we are leveraging our knowledge and insights to support the marine and offshore industries as they explore carbon capture, utilization and storage.  Let us assist you today.


Climate change has taken center stage globally.  Requirements are constantly emerging from regulatory bodies, financial institutions as well as several other organizations, driving companies to not only account for their carbon footprint but to also find ways to reduce it. One of the methods that many companies are exploring is carbon capture, utilization and storage.

How does CCUS work?

CCUS is the process by which CO2 can be captured, cleaned, dehydrated, liquefied, transported and either utilized or be stored at a final location.

  • Capture – Carbon capture technologies capture, absorb, or sequester CO2 through pre-combustion capture, oxy-fuel capture, or post-combustion capture.
  • Transport – Once the CO2 is conditioned, it can be transported through pipelines, ships (CO2 carriers), motor carriers and railways to storage facilities or to directly be utilized.
  • Utilization – CO2 is currently being re-used as a key input in fertilizer, brewing and food industries.  However, there is ongoing research to support CO2 injection into wells to enhance oil recovery and for utilization in methanol production.
  • Storage – Instead of utilization, CO2 can be permanently stored through injection into wells, such as depleted oil or gas reservoirs, coal beds, or saline aquifer or stored through mineral carbonation which creates a solid carbonate form. 

Shipboard Capture

To reach the IMO’s 2030 and 2050 emissions reduction targets, shipboard carbon capture is currently being explored.  In order for CO2 to be captured onboard, additional elements needs to be installed including a CO2 capturing unit, storage tanks and piping systems as well as a component with the capability to liquify the CO2 for transportation.
