Stunning Revelation: Carbon Capture Tech Could Surpass Solar and Nuclear Growth by 2030, Experts Say!

The Role of Carbon Capture and Storage in Climate Mitigation

Carbon capture and storage (CCS) is increasingly seen as a crucial component in the fight against climate change. Despite its potential, the feasibility of scaling CCS to meet global climate targets has been highly debated. Recent initiatives aim to expand CCS capacity by eight times from 2023 to 2030. However, similar efforts a decade ago fell short.

Three critical challenges must be addressed to make CCS a reality. First, we need to accurately predict which CCS plans will succeed. Second, we must project medium-term growth, considering various drivers and barriers. Finally, we need to estimate long-term growth rates, taking into account the future CCS market size.

Historical data and empirical evidence from past technology deployments provide a foundation for addressing these challenges. By examining historical failure rates of planned projects, we can estimate feasible near-term CCS deployment. This estimate helps us project medium-term expansion and long-term growth based on historical analogues.

Our findings show that only a small fraction of climate mitigation pathways align with optimistic CCS growth scenarios. Even under the best conditions, CCS capacity by 2070 and 2100 may fall short of the levels required to meet ambitious climate targets. This underscores the need for realistic expectations and robust planning.

Growth Phases of Emerging Technologies

The development of new technologies, including CCS, follows distinct phases. Initially, a formative phase involves testing and adapting the technology to market conditions. This phase typically covers 0.1% to 2.5% of the market. As the technology matures, it enters an acceleration phase characterized by rapid, quasi-exponential growth.

Eventually, resource constraints and socio-political factors slow the growth, leading to a stable growth phase. Understanding these phases is crucial for projecting CCS deployment. Using feasibility spaces, we compare future CCS growth with historical reference cases to set realistic expectations.

In the formative phase, we project feasible CCS deployment based on current plans and historical failure rates. For the acceleration phase, we use growth rates from nuclear, solar, and wind power as benchmarks. In the stable growth phase, we normalize growth rates to market size to set realistic targets.

This approach can be applied to global, national, and regional targets, and other climate mitigation technologies. Error bars illustrate the uncertainty in feasible deployment over time, helping policymakers set achievable goals.

Requirements for Successful CCS Deployment

Achieving climate targets with CCS requires more plans and fewer failures. Recent data suggests that if all current CCS plans are realized, operational capacity could reach 0.34 Gt/yr by 2030. However, previous waves of CCS plans have failed to meet expectations despite supportive policies.

To succeed, announced CCS plans need to double by 2025, and the failure rate must drop significantly. Historical data shows a high failure rate for CCS projects, particularly in the electricity sector. Current plans are more diversified, which may reduce the overall failure rate.

We estimate that a realistic failure rate could bring CCS capacity to 0.37 Gt/yr by 2030. This would align with the median capacity in the IPCC’s 2°C pathways but fall short of the more ambitious 1.5°C targets. Achieving higher capacities will require unprecedented growth rates.

The success of CCS depends on overcoming technological, economic, and socio-political challenges. Policymakers must create a conducive environment for CCS deployment, including regulatory frameworks and financial incentives.

Feasible CCS Growth Trajectories

CCS must grow at least as fast as wind power to meet climate targets. Our projections show that feasible CCS capacity by 2040 ranges from 0.95 to 4.3 Gt/yr. The upper end of this range requires optimistic assumptions about initial deployment and growth rates similar to historical nuclear power expansion.

Most IPCC pathways envision faster growth than is likely feasible. Only a small percentage of pathways align with realistic growth rates. This highlights the need for careful planning and management to avoid over-reliance on CCS for climate mitigation.

To achieve these growth rates, CCS projects must transition from the formative to the acceleration phase by 2030. This requires a significant increase in planned capacity and a reduction in failure rates. Policymakers should focus on creating market conditions that support rapid CCS deployment.

In conclusion, while CCS has the potential to significantly reduce CO2 emissions, its success depends on realistic growth trajectories and robust policy support. By learning from historical analogues and setting achievable targets, we can ensure that CCS plays a vital role in mitigating climate change.
