To assist in the licensing of CO2 storage sites it is important to be able to provide a realistic, defensible and fully auditable estimate of the storage capacity of geological formations below the UK coastal waters.
We have been involved in storage capacity estimation since the 1990s, when the first project (known as ) on geological storage of CO2 was undertaken. We have applied our expertise in the UK and globally, including India, South Africa, China, Europe and Ireland.

Our work and recognised leadership in storage capacity estimation has led to the BGS’s involvement in a number of international initiatives, including the development of the Carbon Sequestration Leadership Forum storage capacity estimation methodology (Bachu et al., 2007) and as members of the United Nation Task Force on reserve estimates for injection projects.
The level of understanding of the theoretical storage capacity of the UK is mature; our focus is now is on maturing the understanding of UK storage to support development of CCS in the UK as well as engaging with countries who have yet to assess their CO2 storage potential.
UK storage capacity
The BGS was involved in developing the calculation methodology during the UK Storage Appraisal Project (UKSAP) funded by the Energy Technologies Institute (ETI). This was the first study to assess the whole of the UK Continental Shelf for its potential to store CO2 within saline aquifers (brine water-bearing formations), oil fields and gas fields.

is the UK CO2 storage evaluation database providing access to date for over 500 potential storage units in the UK, including saline aquifers and oil and gas fields. For each storage unit, CO2 Stored provides geological parameters, such as:
- porosity and permeability
- a range of storage capacities
- potential geological risks
- economic projection for the cost of storage.
CO2 Stored is a national asset, identifying a geological storage potential of over 70 billion tonnes of storage deep under the UK seabed. The UK is the first country in the world to provide this information online. CO2 Stored is hosted and developed by the BGS in partnership with The Crown Estate.
