CO2 Stored is a web enabled database, containing derived geological data, storage estimates, risk data and economics for nearly 600 potential CO2 storage units located offshore UK. These include oil and gas reservoir and saline aquifers.
The database builds on the work of the UK Storage Appraisal Project (UKSAP), which was commissioned and funded by the Energy Technologies Institute (ETI). The UKSAP study estimated that the UK has a total Theoretical Storage Capacity of 78 GT with 50% confidence, one of the highest in Europe.
The service is subsciption based and aimed at government, research organisations and commercial operators.
The database includes derived data for each storage unit including: location, storage unit type, lithology, water depths, porosity, permeability, formation thickness, formation depth, pressures, and salinity.
Geological risk for each storage unit is also provided. This was assessed by a team of experts and contains geological faulting in the storage unit, caprock, compartmentalisation of the storage unit, likelihood of formation damage information. The risks are summarised in a range of risk profiles for each storage unit.
The Carbon Capture and Storage Association welcomed the launch. "This is a tremendous resource for the CCS industry, regulators and the wider CCS community – and in particular will enable developers of CCS to choose only the best sites for carbon dioxide storage," said Dr Jeff Chapman. The UK Continental Shelf has an enormous capacity to be able to permanently store CO2 . This project will help to make best use of this British resource. The level of knowledge and understanding contained in this website is a world first, and allows the UK to take a leading role in developing an inventory of CO2 storage potential."
