DNV Coordinates Unified Approach to Qualifying CO2 Storage Sites

DNV is now developing a standard methodology for characterizing, selecting and qualifying proper sites for geological storage of CO2 – both offshore and onshore. This work is being carried out together with Norwegian authorities and more than 10 of the world’s key oil, gas and coal players.

DNV has assembled key industry players and launched a joint industry project (JIP) to develop a standard methodology for characterizing, selecting and qualifying proper sites – both offshore and onshore.

This will provide guidance on how to establish permanent, safe and cost-efficient storage of CO2. The JIP is open to new participants until the end of 2008.

The JIP has attracted wide interest from the authorities and oil, gas and coal-fired power industries. In addition to DNV, the partners so far are Gassnova SF (responsible for managing the Norwegian state’s involvement in CCS activities), Gassco AS, IEA Greenhouse Gas R&D Program, StatoilHydro, BP, Shell, Petrobras, RWE Dea, Schlumberger, Vattenfall AB, BG Group and DONG Energy.

"The key to a successful CO2 storage project is appropriate selection criteria and a proper understanding of how to manage risks and geological uncertainties," says DNV.

The current JIP focuses on establishing a transparent, predictable and cost-effective site selection approach by:
• providing guidance on the proper management of risks and geological uncertainties
• providing guidance in deploying concurrent best engineering practices
• providing open references to ensure the confidence and trust of stakeholders and the public
• simplifying demonstrations of compliance with legal and regulatory requirements in legislation, directives, conventions, etc, and harmonizing implementation
• explaining how to obtain emission reduction credits.
The framework developed by the JIP should also provide a protocol with links to decision gates in field development projects to assist operators, authorities, verifiers and other stakeholders to:
• define the desired storage site attributes, including the data and analysis requirements necessary to provide confidence that the storage site has the desired attributes
• assign and rank risks (and uncertainties) based on the available (and missing) data
• define an environmentally friendly and economically acceptable site operation procedure, including compliance with standards, legislation and applicable directives
• define requirements for a Monitoring, Verification, Accounting & Reporting (MVAR) program, including requirements for mitigation and remediation plans
• manage storage sites in accordance with a transparent, consistent and cost-effective process that meets the expectations of the authorities, stakeholders and general public.
