According to the IEA and many others, no single solution but a large range of policies and technologies are needed across every sector to keep climate targets, to go from the Stated Policies Scenarios (STEPS) to the Sustainable Development Scenario (SDS) scenarios in term of level of energy-related and industrial emissions.

Among the panel of listed solutions, classified in three main categories (Efficiency, Renewables and others), Carbon Capture Utilization and Storage (CCUS) has a key role to play.

The Carbon Capture, Utilization and Storage (CCUS) encloses all technologies dedicated to remove CO2 from flue gas and from the atmosphere, to recycle this CO2 for utilization in chemical applications for instance and/or store it in geological cavities 

Depending on the sources, CC(U)S might allow to reduce 5.6 billion tons per annum of CO2 captured and permanently stored in 2050. This projection highlights the need of retrofitting existing infrastructures and deploying carbon capture technologies together with low-carbon technologies.  

Many actors in various sectors are already committing to achieve carbon neutrality by 2050 with new commitments emphasizing CCS as a key solution, one of the first topic selected by the majors involved in the OGCI (Oil & Gas Climate Initiative).

CO2 Capture

Among the energy-related GHG emissions, the power sector is the largest carbon emitter accounting for 40% of the emissions splitted between power coal, gas and oil. Within the Industry sector, cement, iron and steel plants represent approximately 53% of the emissions and are among the hardest to decarbonize with the oil refining activities.


CO2 Gas Drying

The dehydration of CO2 streams presents specificities such as corrosiveness, acid gases co-absorption and TEG recovery. Consequently, for decades, it has been seen as a challenge for the operators. This stands true in various industries and particularly in the oil&gas sector, whether on highly sour natural gases or on pure CO2 streams for enhanced oil recovery (EOR) purpose.
