Carbon capture and storage (CCS) continues to make significant progress around the world against a backdrop of greater climate action from countries and private companies. The Global Status of CCS 2021 demonstrates the critical role of CCS as nations and industry accelerate to net-zero.

CCS networks connecting emissions sources to storage hubs are the most cost-effective deployment method. This report, part of the Circular Carbon Economy series, analyses global emissions and storage basins, identifying potential networks. It outlines CO2 transport design, cost minimisation, and highlights storage availability, technical feasibility, and the need for national assessments and localised pipeline cost models to guide CCS network development worldwide.

CCS is a mature, commercially available technology essential for net-zero and limiting warming below 2°C, requiring a 100-fold capacity increase by 2050. This report reviews policy, legal, and financing factors affecting CCS investability, and provides recommendations for governments to facilitate private sector investment through frameworks, policy, and regulatory measures.

The IEA-SDS scenario requires CCS to deliver 15% of global emissions reductions, demanding a 100-fold capacity increase by 2050, with capital costs of US$655–1,280 bn. This report examines government roles, project finance, green bonds for hard-to-abate sectors, and climate finance support in developing countries to unlock private investment for CCS deployment.

In early 2021, U.S. lawmakers introduced five bipartisan CCS bills to accelerate deployment. This brief, by Matt Bright, examines these bills, the three pillars of U.S. CCS policy, and its historical evolution. It highlights how strong policy drives CCS growth, offering insights into challenges and opportunities for global CCS deployment in the coming decades.

CCS must be globally deployed to reduce emissions, yet few projects exist in developing countries. Commissioned by ClearPath and Southern Company, this report examines climate finance’s role in supporting CCS, addressing existing facility support, deployment barriers, investment risks, and funding mechanisms. Climate finance can boost readiness and close funding gaps for CCS in these regions.

Achieving net zero demands rapid deployment of emissions-reducing technologies. This report, part of the Circular Carbon Economy series, examines blue hydrogen’s role in climate mitigation, covering costs, resource needs, and policy recommendations. Blue hydrogen can accelerate clean hydrogen adoption but requires sustained policy support to meet global climate targets.

CCS is essential for net-zero goals, with deployment costs critical for economic and environmental outcomes. This report, part of the Circular Carbon Economy series, examines CCS technology readiness and cost drivers, including scale, CO2 concentration, energy, and innovation. Advancing technology will reduce costs and enable CCS in hard-to-abate sectors like cement, steel, and DAC.

The Global Status of CCS Report 2020 highlights CCS’s critical role in achieving net-zero by 2050 and reviews milestones from the past year. It covers the global CCS pipeline, policy, storage, and regulation, with regional updates and a technology section showcasing innovations and applications advancing CCS deployment worldwide.

At DOE’s request, the Global CCS Institute studied how ESG ratings influence CCS investment. The assessment examined impacts of ESG ratings on companies, CO2 exposure, CCS’s role in ratings, and links to financing. It also explored climate litigation and policy impacts, clarifying ESG’s complex relationship with CCS deployment and investment.

The Global CCS Institute’s flagship report highlights CCS’s value under two themes: climate and economic benefits. CCS enables deep industrial decarbonisation, large-scale clean hydrogen, low-carbon power, and negative emissions. Economically, it drives growth, creates jobs, supports just transition, fosters innovation, and reuses infrastructure, reducing decommissioning costs while supporting net-zero industries.

As oil and gas companies are evolving their business models in the context of the energy transition,  and a growing number of them are committing to net-zero targets,  CCS has started to feature more prominently in their strategies and investments.
