Supply chain readiness for widespread deployment of carbon capture and storage

There is uncertainty around whether current supply chains are able to cater for the increase in demand which will arise from carbon capture and storage (CCS) deployment. In order to meet the IPCC 2 °C target, 2800 - 4500 CCS plants of 1.7 Mtpa capacity need to be commissioned between 2030 and 2060. This study identifies the bottlenecks in the deployment of different CCS technologies by evaluating technology readiness level (TRL), commercial readiness index (CRI) and the supply chain readiness index (SCRI). Given the time required to establish supply chains, an under-developed supply chain will cause us to fall short of our climate change mitigation targets. Of the issues identified, we believe most process equipment related issues do not disqualify the deployment of a specific technology. Technologies with inefficiencies or low capacity can be addressed with multiple unit operations. However, reliance on specialised materials will limit deployment. Large-scale deployment of CCS is possible with currently available technology. We wish to highlight that increasing supply chain capacity should be a high priority, and advanced planning is required.
