The Strategic UK CO2 Storage Appraisal project completed and published in early 2016 by the ETI/DECC confirmed that the UK Continental Shelf (UKCS) is endowed with a rich and diverse national offshore CO2 storage resource that could be mobilised into service readiness without extensive appraisal programmes. This is due to a wealth of prior knowledge arising from decades of petroleum exploration and development activity from commercial and national organisations. Whilst the UKCS hosts many high quality potential storage sites, the ETI project concluded that the UK’s requirements for CO2 storage through to 2070 could be accommodated by the mobilisation and development of just 8 sites. This portfolio of 8 sites spans a range of geography, geological storage types, development timetables and development risk. Further details are provided here.
In a study on Oil and Gas Diversification for Scottish Enterprise, Pale Blue Dot Energy highlighted the opportunity for Scotland to deploy surplus oil and gas capability on emerging future energy sectors including Wave and Tidal, CCS, Hydrogen and Heat. There is too little focus on Diversification, particularly in the North East. Oil and gas businesses should develop Diversification strategies in order to manage the long-term decline in oil and gas driven by price uncertainty and the Low Carbon transition.
In 2015 the UK Energy Technologies Institute commissioned an industrial project with the objective of materially progressing the development of the National Strategic carbon dioxide storage resource base. The 12 month project, which was funded by the UK Government through the Department of Energy and Climate Change (DECC) and delivered by Pale Blue Dot Energy and its partners Axis Well Technology and Costain Engineering, was published in early May 2016.
D01 – UK CO2 Storage Site Screening and Selection Methodology – 10113ETIS-Rep-01-03
This report documents the screening and selection approach developed for the project to move from an initial inventory of over 570 storage units held within the CO2Stored database down through a “Qualified” and “Select” inventory before a portfolio of five sites was assembled. The project deployed best guidance from the IEAGHG for saline aquifers and also used some multi criteria problem solving to distil the best twenty sites that mapped on the overall project objectives.
These five storage development plans are standalone documents which contain details of the characterisation, modelling, schedule and budget associated with the development of each site to accept the material volumes of CO2 supply required by the ETI Balanced Scenarios work. The reports are also accompanied by downloadable digital models for the Eclipse reservoir simulator. These provide a platform for further work and analysis from other industrial and academic workers.
