DOWNLOAD EBOOKReducing 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.

DOWNLOAD EBOOKCoal has long been the major fossil fuel used to produce electricity. The existing coal-fired power generation fleet consists of over fifteen hundred separate units ranging in size from just a few megawatts (MW) to thirteen hundred (1,300) MW. Together these coal-fired power plants (CFPPs) constitute over 300 gigawatts (GW) of installed electric generating capacity and are responsible for generating more electricity than any other fuel type in the United Sates: between thirty-seven and fifty percent of the total kilowatt-hours (kWh) produced annually during the last decade. 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. This book discusses efficiency improvement options of coal-fired power plants.

DOWNLOAD EBOOKCoal 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.

DOWNLOAD EBOOKIndependent power producers will build a substantial fraction of expected new coal-fired power generation in developing countries over the coming decades. To reduce perceived risk and obtain financing for their projects, they are currently building and plan to continue to build subcritical coal-fired plants with generating efficiency below 40%. Up-to-date engineering assessment leads to the conclusion that supercritical generating technology, capable of efficiencies of up to 45%, can produce electricity at a lower total cost than conventional plants. If such plants were built in Asia over the coming decades, the savings in carbon dioxide emissions over their lifetime would be measured in billions of tons. IPPs perceive supercritical technology as riskier and higher cost than conventional technology. The truth needs to be confirmed by discussions with additional experienced power engineering companies. Better communication among the interested parties could help to overcome the IPP perception issue. Governments working together with industry might be able to identify creative financing arrangements which can encourage the use of more efficient pulverized clean coal technologies, while awaiting the commercialization of advanced clean coal technologies like gasification combined cycle and pressurized fluidized bed combustion.

DOWNLOAD EBOOKAmerica has officially entered the “coal cost crossover” – where existing coal is increasingly more expensive than cleaner alternatives. Today, local wind and solar could replace approximately 74 percent of the U.S. coal fleet at an immediate savings to customers. By 2025, this number grows to 86 percent of the coal fleet. This analysis complements existing research into the costs of clean energy undercutting coal costs, by focusing on which coal plants could be replaced locally (within 35 miles of the existing coal plant) at a saving. It suggests local decision-makers should consider plans for a smooth shut-down of these old plants—assessing their options for reliable replacement of that electricity, as well as financial options for communities dependent on those plants. This report should begin a longer conversation about the most cost-effective replacement for coal, which may include combinations of local or remote wind, solar, transmission, storage, and demand response.

DOWNLOAD EBOOKThis 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.
