In January 2025, representatives from the Department for Energy Security and Net Zero (DESNZ), CO2RE and the Industrial Decarbonisation Research and Innovation Centre (IDRIC) held a workshop on carbon capture, utilisation and storage (CCUS) and engineered greenhouse gas removal (eGGR) technologies. The aims of the workshop were to support DESNZ in identifying the existing technical evidence and pinpoint the gaps for the deployment of CCUS and eGGRs; engage with interested and active organisations in sharing the current barriers and challenges to the deployment of CCUS and eGGRs; understand what technical evidence needs to be gathered to resolve barriers and challenges for CCUS/eGGRs and how; and facilitate knowledge exchange with subject matter specialists. This document describes the discussions that took place and the insights that were shared.
