Oslo: Proper standards and best practices for capture, transmission and storage of CO2, as well as adequate qualification procedures do not currently exist in the oil and gas industry. In order to develop these important guidelines and standards, Det Norske Veritas (DNV) is therefore inviting international industry leaders and key stakeholders to join three significant Joint Industry Projects.
These three joint projects aim to provide a path forward for the industrial opportunity on Carbon Capture and Storage (CCS). The outcome from the projects will provide international standards, methodologies, and guidelines that will form the basis for industrial agreements, and become valuable input to implementation of national requirements. The new standards aim to facilitate and speed up CCS project development, decision processes and ongoing regulatory development, both in Europe and worldwide.
The key challenges the projects will address include how to store CO2 in sub-seabed formations in a safe manner, how to qualify CO2 storage projects and new CO2 capture technology, and what should be the industrial standard for transmission of CO2 in pipelines. Industrial standards and best practices addressing these challenges do not currently exist.
“There are obstacles that need to be dealt with regarding CCS. These are related to the regulatory, legal, economical and technological risks involved in developing and operating a CCS system. Also, there are many different stakeholders with different interests and views. So the agenda is complex. By facilitating these projects on capture, transmission, and storage of CO2, DNV is contributing to the removal of several important barriers in order to realize the full vision of CCS,” says Hans Axel Bratfos, head of DNV’s Cleaner Energy department.
“Due to DNV’s in-depth knowledge coupled with our role as independent partner, we are every year facilitating a great number of Joint Industry Projects in order to safeguard life, property and the environment. DNV is an independent foundation, and our role for 143 years has been to assist in balancing the needs of business and society. The CCS challenge is exactly about balancing the needs of business and society,“ explains Kjell Eriksson, the director of service and technology development at DNV Energy.
There is a need for developing an industry guideline or recommended practice for:
- Qualification of technologies for power generation with capture of CO2. New partners are invited to do case studies and test new elements on power technologies with capture of CO2 in accordance with the new guideline under development. Aker Kværner, Statoil, Norsk Hydro, and Statkraft are already involved.
- Transmission of CO2 in pipelines. Relevant companies and organisations are by this invited to become partners in a Joint Industry Project which will develop and recommend best practice as an industry guideline for transportation of CO2 in pipelines.
- Qualification of Sites and Projects for Geological Storage of CO2. Relevant companies and organisations are by this invited to become partners in a Joint Industry Project developing a methodology and recommended best practice (RP) to select and qualify sites and projects for storage of CO2 in sub-seabed formations.
PROJECT DETAILS
1) The development of a guideline for the qualification of power generation technologies involving the capture of CO2
The development of the guideline has already been organised as a Joint Industry Project (JIP) involving Aker Kværner, Statoil, Norsk Hydro, Statkraft and DNV as partners. The project has received funding from Gassnova, the Norwegian national centre for sustainable gas technologies.
Scope
The guideline will be a supplement to DNV’s general procedure for technology qualification (DNV-RP-A203). The new guideline will provide recommendations on how to qualify CO2 capture technologies in power generation.
Content
The procedure explains in detail how to identify, describe, and manage risks, such as failure modes or threats, as well as assuring expected functional requirements, involved in the implementation of new CO2 capture technology in a quantitative way by following a set of sequential steps known as the qualification process.
Case studies
Further work will focus on testing the procedure on selected CO2 capture technologies. New participants are welcome to perform their case studies based on the developed guideline. These case studies will provide input for possible updates of the qualification procedure.

2) The development of a recommended practice for the transmission of CO2 in pipelines
Relevant companies and organisations are invited to become partners in the world’s first Joint Industry Project to develop a recommend best practices as an industry guideline for the transportation of CO2 in pipelines.
Scope
The Joint Industry Project will be related to the transportation of CO2 in offshore pipelines. There are several challenges involved in transporting dense phase CO2. The work will be based on a gap analysis that identifies the challenges related to the transportation of CO2, using the prevailing pipeline industry standard (DNV OS – F101) as a reference.
Content
There are several challenges related to the transportation of dense phase CO2 which need to be further addressed and clarified, including:
- The classification of CO2 as a transport medium, related to OS – F101
- The significance of contamination to the properties of CO2
- The issue of corrosion – e.g. the determination of acceptable humidity levels and the possible need for corrosion inhibitors, and the improvement of the modelling tools for corrosion-rate prediction
- Issues related to safety, the environment, reliability, maintainability and monitoring.

3) The development of a methodology and a guideline for the qualification of sites and projects for the geological storage of CO2
Relevant companies and organisations are invited to become partners in the world’s first Joint Industry Project to develop a methodology and recommended practice for the selection and qualification of sites and projects for the storage of CO2 in underground formations.
Scope
The Joint Industry Project will stipulate provisions for the initial site selection of geological formations for the storage of CO2. The initial focus will be sub-seabed. The qualification procedure will limit and manage the uncertainties and risks related to storing CO2 in sub-seabed formations. The intended users of the guideline are operators, authorities and other stakeholders participating in the selection, project planning and approval process of a CO2 storage project. Links to relevant regulations, directives and conventions will be provided.
Content
A risk-based qualification approach is suggested. The provisions will describe necessary and appropriate risk mitigation measures, the need for monitoring and verification data, the verification requirements, the remediation plan, and the appropriate tools and models that need to be further developed.
Case studies
In association with the JIP, a series of case study projects may be carried out to test the methods. The processed results may be included as examples of how to apply the RP.
