Coal power plants generate about half of the United States' electricity and are expected to remain a key energy source. Coal power plants also account for about one-third of the nation's emissions of carbon dioxide (CO2 ), the primary greenhouse gas that experts believe contributes to climate change. Current regulatory efforts and proposed legislation that seek to reduce CO2 emissions could affect coal power plants. Two key technologies show potential for reducing CO2 emissions: (1) carbon capture and storage (CCS), which involves capturing and storing CO2 in geologic formations, and (2) plant efficiency improvements that allow plants to use less coal. The Department of Energy (DOE) plays a key role in accelerating the commercial availability of these technologies and devoted more than $600 million to them in fiscal year 2009. Congress asked GAO to examine (1) the maturity of these technologies; (2) their potential for commercial use, and any challenges to their use; and (3) possible implications of deploying these technologies. To conduct this work, GAO reviewed reports and interviewed stakeholders with expertise in coal technologies. DOE does not systematically assess the maturity of key coal technologies, but GAO found consensus among stakeholders that CCS is less mature than efficiency technologies. Specifically, DOE does not use a standard set of benchmarks or terms to describe the maturity of technologies, limiting its ability to provide key information to Congress, utilities, and other stakeholders. This lack of information limits congressional oversight of DOE's expenditures on these efforts, and it hampers policymakers' efforts to gauge the maturity of these technologies as they consider climate change policies. In the absence of this information from DOE, GAO interviewed stakeholders with expertise in CCS or efficiency technologies to identify their views on the maturity of these technologies. Stakeholders told GAO that while components of CCS have been used commercially in other industries, their application remains at a small scale in coal power plants, with only one fully integrated CCS project operating at a coal plant. Efficiency technologies, on the other hand, are in wider commercial use. Use of both technologies is, however, contingent on overcoming a variety of economic, technical, and legal challenges. In particular, with respect to CCS, stakeholders highlighted the large costs to install and operate current CCS technologies, the fact that large scale demonstration of CCS is needed in coal plants, and the lack of a national carbon policy to reduce CO2 emissions or a legal framework to govern liability for the permanent storage of large amounts of CO2. With respect to efficiency improvements, stakeholders highlighted the high cost to build or upgrade such coal plants, the fact that some upgrades require highly technical materials, and plant operators' concerns that changes to the existing fleet of coal power plants could trigger additional regulatory requirements. CCS technologies offer more potential to reduce CO2 emissions than efficiency improvements alone, and both could raise electricity costs and have other effects. Most stakeholders told GAO that CCS would increase electricity costs, and some reports estimate that current CCS technologies would increase electricity costs by about 30 to 80 percent at plants using these technologies. DOE has also reported that CCS could increase water consumption at power plants. Efficiency improvements offer more potential for near term reductions in CO2 emissions, but they cannot reduce CO2 emissions from a coal plant to the same extent as CCS. GAO recommends that DOE develop a standard set of benchmarks to gauge and report to Congress on the maturity of key technologies. In commenting on a draft of this report, DOE concurred with our recommendation.

Coal has long been the major fossil fuel used to produce electricity. However, coal-fired electric power plants are one of the largest sources of air pollution in the United States, with greenhouse gas (GHG) emissions from burning of fossil fuels believed to be the major contributor to global climate change. Regulations under development at the Environmental Protection Agency (EPA) would impose new requirements on fossil-fuelled (mostly coal-fired) power plants (CFPPs) to control GHG emissions. This book focuses on efficiency improvements to power plants, and discusses retrofits, technologies, and other modifications to facility operations which offer the potential to improve power plant efficiency and reduce CO2 emissions.

This book presents the evolution toward advanced coal-fired power plants. Advanced power plants with an efficiency level of 45% are today commercially available and even more efficient plants are in their development phase. Considering that presently many pulverized coal-fired power plants operate with an efficiency of about 32%, an improvement of more than 40% specific coal consumption and CO2 discharge can be achieved. Before trying to apply as a secondary measure the use of carbon sequestration, it seems that this 40% specific CO2 discharge reduction as a primary measure can much easier be achieved. The effect of power generation on the environment can be drastically improved by the use of flue gas cleanup systems in advanced pulverized coal-fired power plants (SO2 emission reduction from 40 to 1.4 lb/MWh and NOx emission reduction from 7.5 to 0.64 lb/MWh). With an increased number of coal-fired plants, CO2 discharge and emissions can be reduced, even with an increase of electric power generation in the US by 38% over the next 20 years. Even though the book concentrates on pulverized coal-fired power plants, it also discusses and compares other options like fluidized-bed combustion and coal gasification.

Coal accounts for approximately one quarter of world energy consumption and of the coal produced worldwide approximately 65% is shipped to electricity producers and 33% to industrial consumers, with most of the remainder going to consumers in the residential and commercial sectors. The total share of total world energy consumption by coal is expected to increase to almost 30% in 2035. This book describes the challenges and steps by which electricity is produced form coal and deals with the challenges for removing the environmental objections to the use of coal in future power plants. New technologies are described that could virtually eliminate the sulfur, nitrogen, and mercury pollutants that are released when coal is burned for electricity generation. In addition, technologies for the capture greenhouse gases emitted from coal-fired power plants are described and the means of preventing such emissions from contributing to global warming concerns. Written by one of the world’s leading energy experts, this volume is a must-have for any engineer, scientist, or student working in this field, providing a valuable reference and guide in a quickly changing field.

Reducing carbon dioxide emissions from coal plants can cut greenhouse gas emissions. One option is to replace some coal power with natural gas (NG) generation, a low carbon source of electricity, by increasing the power output from underutilized NG plants. This report provides an overview of the issues. Contents: (1) Intro.; (2) Background on Gas-Fired Generation and Capacity: Trends; Factors Supporting the Boom in Gas-Fired Plant Construction; Carbon Dioxide Emissions; (3) Coal Displacement Feasibility Issues; Estimates of Displaceable Coal-Fired Generation and Emissions; Transmission System Factors; Long-Distance Transmission Capacity; Transmission System Congestion; NG Supply and Price; NG Transport. and Storage.
