CO2 Storage and Transportation Best Practice

Thursday, May 15, 2014

A CO2 storage and transportation best practice working group meeting was held on the 2nd Guangdong International CCUS Conference.

Per Chriter Lund made a speech titled ‘Validation, Verification and Certification of CO2 Geological Storage Sites and Projects’.

First, he introduced the leading technical advisor DNV GL. DNV GL enables safe, reliable and enhanced performance in oil and gas projects and operations; they provide integrated services in technical and marine assurance and advisory, risk management advisory and offshore classification.

The company’s DNV-RP-J202 for CO2 Pipelines and DNV-RP-J203 for CO2 Storage were used in Guangdong CCUS activities.

They have done independent review of storage component of QUEST project in Alberta, Canada; ZeroGen project in Queensland, Australia; Storage Development Plan for QUEST project; feasibility of portfolio of candidate storage sites for the CarbonNet project in Victoria, Australia; and +Gorgon CO2 injection project successively in the past three years.

Professor Stuart Haszeldine then discussed about storage and transport best practice. Finding suitable storage sites can be a problem, Regional Survey Atlas is often used. Many projects have failed, because good storage sites cannot be proven, Injectivity, pressure and seal are vital. Storage can take a long time to prove, so it is better to start evaluating storage 5 years ahead of when it is needed.

First projects may be simple and expensive, but better integration reduces costs. CO2-EOR could make money, but that requires good platforms, expensive refits and creative funding. Shipping can be viable as a flexible low-cost delivery. And it is also necessary to conduct baseline reservoir and environment monitoring. (Linkschina)
