Request for proposal for the DECC Strategic UK CCS Storage Project. The primary objective of this Project is to progress the appraisal of five stores, downselected as part of the Project, towards readiness for FID so that prospective capture projects will see an abundance of storage options 30 years into the future. The work will add significantly to the de-risking of these stores and be transferable to storage developers to complete the more capital intensive parts of storage development.
