“…In this case, the per stored tonne cost of a point-to-point system may be anywhere from 30% to 350% higher than would be the case for an optimal network 60 . Compounding the uncertainty is the level of renewable energy adoption and the concomitant reduction in the utilization of CCS fossil-fired power plants favoring a smaller size pipeline investment 61 . These factors suggest that initial deployment of CCS is highly unlikely to be part of a scale-optimized network and, in the absence of enforceable planning legislation, it will be difficult to reverse the trend in the future.…”

Carbon capture and storage (CCS) for fossil fuel power plants is perceived as a critical technology for climate mitigation. Nevertheless, limited installed capacity to date raises concerns about CCS ability to scale sufficiently. Conversely, scalable renewable electricity installations-solar and wind-are already deployed at scale and have demonstrated a rapid expansion potential. Here we show that power sector CO 2 emission reductions accomplished by investing in renewable technologies generally provide a better energetic return than CCS. We estimate the electrical Energy-Return-on-Energy-Invested ratio of CCS projects accounting for their operational and infrastructural energy penalties to range between 6.6:1 and 21.3:1 for 90% capture ratio and 85% capacity factor. These values compare unfavorably to dispatchable scalable renewable electricity with storage, which ranges from 9:1 to 30+:1 under realistic configurations. Therefore, renewables plus storage provide a more energetically effective approach to climate mitigation than constructing CCS fossil power stations.

“…Field F7.4 (67 papers, 31% of C7) explored optimisation models for CO 2 transport. Key papers included Fimbres and Wiley [159] (d = 140), who, after reviewing several CCS network optimisation methodologies, proposed to start with determining the characteristics of a near-optimal CCS pipeline network by taking a whole systems approach to the minimum total cost per tonne of CO 2 avoided in a "steady-state"; Knoope et al [160] (d = 127), who modelled a transportation network under uncertainty using a real option approach (ROA), and without uncertainty, using a perfect foresight (PF) model; and Mechleri et al [161] (d = 110), who presented an optimisation methodology for the "right-size" CO 2 transport infrastructure, by taking into account the future variability in CO 2 flow (including periods of zero flow) due to an increasing share of renewables, and therefore a reduced load of fossil fuel-fired power plants.…”

For many years, carbon capture and storage (CCS) has been discussed as a technology that may make a significant contribution to achieving major reductions in greenhouse gas emissions. At present, however, only two large-scale power plants capture a total of 2.4 Mt CO 2 /a. Several reasons are identified for this mismatch between expectations and realised deployment. Applying bibliographic coupling, the research front of CCS, understood to be published peer-reviewed papers, is explored to scrutinise whether the current research is sufficient to meet these problems. The analysis reveals that research is dominated by technical research (69%). Only 31% of papers address non-technical issues, particularly exploring public perception, policy, and regulation, providing a broader view on CCS implementation on the regional or national level, or using assessment frameworks. This shows that the research is advancing and attempting to meet the outlined problems, which are mainly non-technology related. In addition to strengthening this research, the proportion of papers that adopt a holistic approach may be increased in a bid to meet the challenges involved in transforming a complex energy system. It may also be useful to include a broad variety of stakeholders in research so as to provide a more resilient development of CCS deployment strategies.

“…On a decadal time-scale, CCS capacity will be gradually deployed and ostensibly lead to an increase in target CO 2 injection rates. Meanwhile, the deployment of extensive amounts of intermittent renewable power could lead to displacement of thermal generation as well as an increased, hourly dependent, variability in storage demand for CO 2 from power [15,16,17,18]. Investigating the eect these variable rates of CO 2 injection can have on regional reservoir behaviour and storage supply is the focus of our current study.…”
