Assured storage capacity (1)
Widespread and large scale Carbon dioxide Capture and Storage (CCS) is a key part of meeting our emission targets
Assured storage capacity is fundamental to the success of individual CCS projects but also to implementation of CCS on a national and global scale
Need to be able to safely store all the captured CO2
Assured storage is needed to take investment decisions
Static capacity estimates indicate there is storage space for Europe, need to advance to national and European dynamic storage atlas
Storage sites need to be ready in time

Assured storage capacity (2)
Need to understand the reservoir characteristics in order to predict how the CO2 and reservoir will behave at any particular storage site
Where are the boundaries of the reservoir and storage complex?
Is the geological formation uniform or heterogeneous?
How many wells will be needed to access the storage capacity? (dynamic storage capacity)

Assured storage capacity (3)
Data is one of the key issues in assuring storage capacity
more data will result in a more accurate assessment
There are lots of data in the public domain or data collected during other resource assessment activities
Clear communication on how the storage capacity has been estimated and confidence in the data is essential

Assured storage capacity (4)
Assured capacity also relies on
Regulatory regime (are you allowed to utilise that storage site?) Finance (how much will it cost to access that storage space?)

Field Research Station #1 well, Canada
Flexible storage solutions
Strategic planning for CCS is required
Consider national and international energy landscape
Assess how to best satisfy the requirements of society for affordable, dependable and sustainable energy sources with low greenhouse gas emissions
Ensure the most efficient use of the subsurface
Regulatory issues need to be considered (e.g. for example, how will stacked storage be permitted?)

Safe storage (1)
How can CO2 storage be implemented in a manner that is safe for humans and the environment?
Ensuring that CO2 storage is carried out in a safe manner requires actions at all stages of the CO2 storage lifecycle…
thorough pre-injection risk-led geological site characterization (includes testing the reservoir and seal response to CO2)
effective monitoring, measurement and verification (MMV) of the site during injection and plan for how to respond to any irregularities
understanding of long term storage site evolution during the post-injection phase.

Safe storage (2)
Demonstrating the site is behaving as expected through monitoring, measurement and verification is key to ensuring the CO2 storage site is safe
Models of the storage site are iteratively updated as new data and new techniques become available

Safe storage (3)
Best practice recommendations on understanding how risks to storage site security can be mitigated have been produced by recent projects
Techniques and technologies for rapidly detecting and confirming leakage (if it occurs) have been proven at pilot and natural leakage sites

Practical experience Demonstration projects store CO2 and prove the technology at
scale
Practical experience gained at pilot and test injection sites and
field laboratories is important to move CCS forward Pilot sites allow demonstration of innovative monitoring technologies
and strategies
Experiments at natural analogue sites are also important in
understanding longer-term processes and potential impacts of
leakage

Public engagement (1)
Onshore CO2 storage pilot projects offer an opportunity for public engagement and knowledge transfer
Communication with local community needs to be transparent and needs to start in the very early phase of the project

Public engagement (2)
Communication on geological storage of CO2 is one of the main activities undertaken by CO2GeoNet in its role as a pan-European research Association
