Impressed by the Potential of TCM
«For many of the participants from industrial companies with no prior knowledge of TCM, the visit to Mongstad provided a true “aha” moment. They were impressed by the scale of the facility and the potential the technology center represents for developing efficient and secure solutions for carbon capture and storage (CCS).»
TCM regularly receives visitors from many countries eager to see and learn about technologies for CO₂ capture. Recently, senior engineer Klas Solberg of DNV and Gaute Svenningsen, group leader at the Institute for Energy Technology (IFE), led a large delegation of representatives from companies participating in three international research projects related to various aspects of carbon capture, transport, and storage. These delegates gathered for project meetings in Bergen and made a joint excursion to learn more about what TCM represents and can offer.
“After the visit, several participants expressed that testing technologies at TCM or receiving assistance to find solutions to specific challenges would be relevant for advancing their emission-reducing projects. This included large oil companies, industrial enterprises, and companies supplying materials for constructing CO₂ capture or storage facilities.”
Studying Impurities in CO₂ in Ship Tanks and Pipelines
At IFE, the KDC project (Kjeller Dense Phase CO2 Corrosion) is now in its fourth phase. All phases have received financial support from CLIMIT in addition to industry funding. KDC-IV began in 2023 and will continue until 2028. The project brings together 22 participants from industries worldwide.
Rolf Nyborg, explains that the KDC projects focus on studying the effects of impurities in CO₂ on corrosion in pipelines and ship tanks.
“The goal is to identify combinations of concentrations of various impurities in CO₂ that ensure safe CO₂ transport. IFE conducts a series of laboratory experiments with controlled amounts of different impurities at ppm levels to study this. This work is central to the development of CO₂ specifications for safe CO₂ transport internationally,” he says.
Material Selection for Injection Wells
IFE is also behind the CO2WellMat project (Materials for CO₂ injection wells), which started in 2017. With 16 participating companies, including several steel producers the project is now in phase II.
The CO2WellMat projects focus on studying which stainless steel alloys can be used in the lower sections of CO₂ injection wells, where injected CO₂ meets formation water in the reservoir where CO₂ will be stored. The project examines the effects of impurities in the injected CO₂ on corrosion in various steel and nickel alloys.
This work is crucial for material selection in injection wells for several planned CO₂ storage projects.
Investigating Sulphide Stress Cracking and Corrosion Damage Caused by Hydrogen Sulfide
DNV’s CO2 Safe & Sour is another collaborative project, involving 15 industrial companies from Norway and abroad. Initiated in 2022, the project examines how increasing levels of hydrogen sulfide (H₂S) will affect the risk of sulfide stress corrosion (SSC) and other corrosion damage in carbon steel pipelines used for CCS.
”The goal is of the project is to provide clearer guidance related to the level of H2S in the CO2 stream to be transported in CCS pipelines and in particluar to establish limits for carbon steel with respect to H2S in dense phase CO2.” Says project manger Klas Solberg
The project will provide general recommendations for broad industry use and will lead to an update of the DNV-RP-F104 “Design and operation of carbon dioxide pipelines.”
