Project Overview
Project Flow
Over a 10 month period develop practical cost effective storage options that
contribute to an extendable storage scheme for 1500MT of storage capacity
and 50MT/y of injection capacity by 2030

Project Objectives• Develop storage options which
put UK on track to injecting
50MT/a CO2 by 2030, and with
1500MT of appraised storage
• Screen and de-risk commercially
attractive stores, some potentially
ready for 2026
• Estimate the cost and schedule to
provide this capacity
• Make public the findings
Value Objective• Materially progress development
of UK CO2 storage capacity.
• Inform roll-out strategies
• Do so within 12 months and at a
cost not exceeding £2.5m
• Completed April 2016
Key Findings
Varied Portfolio
The portfolio of 5 sites selected is geographically and technically diverse, and presents options for clean energy and industrial development around the UK.
Only 2 of the 5 sites require any further appraisal drilling before an investment decision.
Alongside the detailed KT from UK FEED projects these sites characterise one of the most comprehensive and mature CO2 storage potential propositions available within the public domain

Key Findings200MT – UK FEED Studies
1645MT – including this study
7.1 GT – Top 20 sites
8.6 GT – All qualified sites
78GT – UKCS potential
The UKCS is endowed with a rich and diverse national
offshore CO2 storage resource, key components of
which can be brought into service readiness without
extensive appraisal programmes thanks to decades of
petroleum exploration and development activity.

Portfolio Assessment
Conclusions
Resource Potential 1.6Gt could be stored by 2070 at up to 45MT/yr across 8 sites
O&G legacy is valuable – skills, information and subsurface understanding
Timing Ability to bring online in early 2020s
Only two of five sites required further pre FID appraisal drilling
Risk Key remaining risks involve the integrity of abandoned legacy wells
May impact cost and MMV plan in detail
Contribution to Power Generation Cost £14.4/T levelised cost of transportation and storage
£6.9/MWh to the levelised cost of gas fuelled electricity
Focus of cost reduction efforts Operating cost of the injection facility and the wells
Storage - accounts for 65 – 85% of the total

Summary
Highlights The UKCS is endowed with a rich and diverse offshore CO2 storage resource
Key components can be brought into service readiness without extensive appraisal drilling
Portfolio is geographically and technically diverse
One of the most mature CO2 storage propositions in the public domain
Concerns Additional costs may be presented by legacy well risk to managing containment of CO2 in storage sites
In general, most oil and gas infrastructure is likely to be unsuitable for CO2 storage use.
What Next? Rebuild momentum and engage with potential developers
More work required around consenting of open aquifer sites
R&D should focus primarily upon Storage Efficiency and Operational Efficiency
Work with OGA:-
National archive is lacking key data important for detailed storage assessment
Consider changes to decommissioning process in CO2 storage areas to prevent them from being sterilised for subsequent use.
