Nye interessante IEAGHG-rapporter

IEAGHG har kommet med noen nye interessante rapporter om det CLIMIT-støttede Recap-prosjektet og CO2-migrasjon.

2017-TR8 "Understanding the Cost of Retrofitting CO2 capture in an Integrated Oil Refinery (RECAP Project)"

IEAGHG has undertaken a series of projects evaluating the performance and cost of deploying CO2 capture technologies in energy intensive industries such as cement, iron and steel, hydrogen and pulp and paper. In line with these activities IEAGHG initiated this project in collaboration with CONCAWE, CLIMIT Demo, and SINTEF Energy to evaluate the performance and cost of retrofitting CO2 capture in an integrated oil refinery.

The global refining sector contributes around 4% of the total anthropogenic CO2 emissions. CO2 capture and storage has been recognised as one of the technologies that could be deployed to achieve deep reduction of CO2 from this as well as other industry sectors.

The main purpose of the study was to evaluate the cost of retrofitting CO2 capture in a range of refinery types typical of those found in Europe.

2017-08 "CO2 Migration in the Overburden"

At CO2 storage sites, large-scale overburden heterogeneities and introduced man-made pathways (e.g. wells) could potentially breach the sealing strata and promote the migration of injected CO2 in the dense, gaseous or dissolved phase. The ability to fully characterise the overburden would therefore allow identification of the preferred CO2 vertical migration pathways which will then encourage more complete risk assessments. Overall this will allow for more focussed monitoring efforts and will lead to the deselection of sites prone to vertical migration.

This study was conducted to assess the natural rates of CO2 and fluid migration that occur in the overburden (defined as the entire geological succession above the target reservoir formation with the lowermost stratum forming the primary seal) and the potential rates that may arise in the unlikely event of unintended migration outside a designated storage complex. The aim was to better inform risk assessments for CO2 storage sites by providing relevant information on the effect of large-scale features associated with natural fluid migration analogues in the overburden.
