CCS Case Study

Axis was awarded (with Pale Blue Dot) a major project to identify the next phase of UKCS sites to store CO2 emissions from coal and gas power stations and heavy industry plants.  This 12 month project was funded with £2.5m from DECC.  It progressed the appraisal of five selected storage sites towards readiness for Final Investment Decisions, de-risking these stores for potential future storage developers.

This project identified 20 specific CO2 storage sites (from a potential 579 sites) which together represent the tip of a very large strategic national CO2 storage resource potential, estimated to be around 78GT (78,000 million tonnes). The top 15% of this potential storage capacity would last the UK around 100 years.

Five of these sites were then selected for further detailed analysis given their potential contribution to mobilise commercial-scale carbon, capture and storage (CCS) projects for power and industrial use in the UK. Outline storage development plans and budgets were prepared for each.

The workscope included:

• Data collection, screening and understanding (579 fields)

• Initial analysis of preferred sites (20 fields)

• Detailed static and dynamic subsurface and wells modelling (5 fields)

• Identify storage development scenarios including assessment of capacity, injectivity, containment and cost

• Generate injection profiles and monitor 1000 year plume migration

• Identify and understand key subsurface and wells risks

• Prepare detailed technical reports and presentations including FDP and non-technical summary report

• Present results at public meeting in London

• Provide intensive project management and incorporate stakeholder peer review
