Executive Summary
The International Energy Agency (IEA) has conducted a global study focusing on recently constructed fossil-fuel fired power plants. This report specifically evaluates the most cost-effective plants with the highest efficiencies and lowest emissions. The aim is to highlight the availability of efficient technologies and operational practices that could be deployed globally, particularly in countries with high fossil fuel usage.
Key Findings
-
Efficient Technologies Available: Reliable operation at high efficiency for coal-fired power generation is possible at a commercially acceptable cost, utilizing advanced technologies like pulverized coal combustion (PCC) with supercritical steam turbine cycles. This is complemented by the application of Integrated Gasification Combined Cycle (IGCC) and natural gas-fired combined cycle plants.
-
Case Studies: Eight detailed case studies are presented, covering coal-fired plants in Europe, North America, Asia, and Africa, and a natural gas-fired plant in Europe. These studies showcase the technologies and operational strategies employed to achieve high efficiencies and low emissions.
-
Technological Review: An overview of IGCC technology is provided, highlighting its potential in achieving higher efficiency and lower emissions compared to traditional coal plants.
-
Challenges and Opportunities: The report identifies the challenges in deploying these technologies globally, emphasizing the need for supportive policies that encourage operational best practices and continuous technological advancements.
-
Policy Recommendations: It suggests measures for wider deployment of these technologies, especially in countries with significant fossil fuel usage, aiming to enhance energy efficiency and reduce environmental impact.
Conclusion
This report serves as a technical foundation for further analysis on the upgrading of older coal-fired power plants in major coal-consuming countries. It underscores the availability of efficient technologies and operational practices, advocating for their wider adoption and the integration of environmental considerations into energy policy-making.
