Summary of "Carbon Capture and Storage in Developing Countries: A Perspective on Barriers to Deployment"

Core Content

This World Bank report provides an analysis of the challenges and opportunities for deploying carbon capture and storage (CCS) technologies in developing countries, with a focus on the Southern African and Balkan regions. It examines the economic, legal, and financial barriers to CCS deployment and explores how these can be addressed to support the integration of CCS into low-carbon growth strategies.

Main Viewpoints

• CCS as a Mitigation Technology: CCS is seen as a key technology for reducing greenhouse gas (GHG) emissions in the power and industrial sectors. It can serve as a technological bridge to achieve mid-term emission reduction goals.
• Economic Challenges: The report highlights that CCS technologies are currently expensive, with significant increases in the levelized cost of electricity (LCOE) due to the energy penalty and capital costs. The economic feasibility of CCS depends heavily on the price of carbon and the availability of enhanced hydrocarbon recovery (EOR/ECBM) benefits.
• Legal and Regulatory Barriers: Legal frameworks in developing countries are often underdeveloped or inconsistent, creating uncertainty for investors. The report reviews international and regional legal instruments and suggests that harmonizing and strengthening these frameworks is essential for CCS deployment.
• Climate Finance: Climate finance mechanisms, including the Clean Development Mechanism (CDM), are critical for supporting CCS projects in developing countries. However, accessing these funds remains challenging due to the complexity of project design and the lack of a clear policy environment.
• Project Finance Structures: The report outlines various project finance structures that can be used to support CCS deployment, including concessional financing and blended debt instruments. These structures can help reduce the financial burden and make CCS projects more attractive to investors.

Key Information

Economic Impacts

• LCOE Increases: The report models the impact of CCS on the levelized cost of electricity (LCOE), showing that CCS increases LCOE by varying percentages depending on the technology and carbon price.
• Carbon Price Influence: A carbon price of $100 per ton CO₂ is found to be necessary for CCS to be economically competitive in Southern Africa, compared to $50 per ton in the Balkans.
• EOR/ECBM Benefits: Enhanced oil recovery and enhanced coal-bed methane recovery can offset some of the costs of CCS, making it more economically viable in certain regions.

Legal and Regulatory Frameworks

• International Instruments: The report discusses the role of international agreements such as the Kyoto Protocol, the UNFCCC, and the CDM in facilitating CCS deployment.
• National Legal Regimes: It reviews the legal frameworks in Southern Africa and the Balkans, noting that many countries lack comprehensive regulations for CCS.
• Recommendations: The report recommends strengthening legal frameworks, improving transparency, and creating clear policy signals to reduce investor risk and encourage CCS deployment.

Climate Finance

• Role in CCS Deployment: Climate finance is essential for funding CCS demonstration and deployment projects in developing countries.
• Access Challenges: CCS projects face significant challenges in accessing carbon finance due to the complexity of project design, lack of policy clarity, and limited availability of financial instruments.
• Good Practice: The report identifies key components for good practice in CCS project design and operation, including robust legal frameworks, clear policy signals, and access to financial support.

Project Finance Structures

• Blended Debt Instruments: The report suggests using blended debt instruments to reduce the cost of capital for CCS projects.
• Concessional Financing: Concessional financing is found to be effective in reducing the LCOE of CCS projects, particularly for integrated gasification combined cycle (IGCC) plants.
• Impact on Electricity Rates: The report shows that CCS can increase electricity rates, but the extent of the increase depends on the level of carbon pricing and the efficiency of the power plant.

Conclusion

The report concludes that while CCS has the potential to significantly reduce GHG emissions in the power sector, its deployment in developing countries faces numerous economic, legal, and financial barriers. Addressing these barriers requires a combination of national and international efforts, including the development of supportive legal frameworks, the availability of climate finance, and the implementation of effective project finance structures. The findings suggest that a carbon price of $100 per ton CO₂ is necessary for CCS to be economically competitive in Southern Africa, while in the Balkans, a lower price may suffice. The report also emphasizes the importance of EOR/ECBM in reducing the costs of CCS and making it more viable in certain regions.

Key Findings

• CCS technologies are still in the early stages of development and require large-scale demonstration to overcome technical and economic challenges.
• Legal and regulatory frameworks in developing countries are often inadequate, creating uncertainty for investors.
• Climate finance is crucial for supporting CCS projects, but access remains limited.
• Project finance structures, including concessional financing and blended debt instruments, can help reduce the cost of capital for CCS projects.
• The economic feasibility of CCS depends on the carbon price and the availability of EOR/ECBM benefits.
