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 CO

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 CO

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?)

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 CO

storage be implemented in a manner that

is safe for humans and the environment?

Ensuring that CO

storage is carried out in a safe

manner requires actions at all stages of the CO

storage

lifecycle…

thorough pre-injection risk-led geological site

characterization (includes testing the reservoir and seal

response to CO

)

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 CO

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 CO

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 CO

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 CO

is one of

the main activities undertaken by CO

GeoNet in its role
