This work analyses the carbon dioxide (CO2) capture system operation within the Electric Reliability Council of Texas (ERCOT) and Great Britain (GB) electric grids using a previously developed first-order hourly electricity dispatch and pricing model. The grids are compared in their 2006 configuration with the addition of coal-based CO2 capture retrofits and emissions penalties from 0 to 100 US...

Compressed air energy storage (CAES) is one of the large-scale energy storage technologies utilized to provide effective power peak load shaving. In this paper, a coal-fired external combustion CAES, which only uses coal as fuel, is proposed. Unlike the traditional CAES, the combustion chamber is substituted with an external combustion heater in which high-pressure air is heated before entering...

Coal-fired power plants in the United States may have to reduce their mercury emissions by up to 90% by 2007 2009 due to proposed regulations that could affect up to 1,100 utility boilers. Air pollution control system components such as electrostatic precipitators, baghouses, NOx reduction catalysts, SO2 scrubbers, and their various configurations in utility applications significantly impact me...

In addition to wind and photovoltaic power, concentrating solar thermal power (CSP) will make a major contribution to electricity provision from renewable energies. Drawing on almost 30 years of operational experience in the multi-megawatt range, CSP is now a proven technology with a reliable cost and performance record. In conjunction with thermal energy storage, electricity can be provided ac...

I am pleased to be here today to share with you our views about the benefits that Integrated Gasification Combined Cycle (IGCC) technology can deliver. IGCC can cost effectively produce power from solid fuels, such as coal, with substantial environmental benefits over other coal power generation technologies. If IGCC is adopted as the preferred coal based power generation technology, it will he...

The radioactivity in human tissues (lungs) obtained from the dead body of people who died by lung cancer in the region of Ptolemais, Northern Greece, where 16 units of 4 major coal-fired power plants are in operation, was studied. The specific activities of radioactive nuclides searched for in human tissues were not remarkable. The syndrome of lung cancer deaths at that area which showed an inc...

1. The Three E’s of Sustainable Development In October 2002 the 16th Party Congress established the goal of expanding China’s economy fourfold by 2020 and defined the Three E’s strategy for economic development, energy security, and environmental protection. In pursuing these goals, China’s energy system cannot continue to expand using the current approach. The risks are that: • China will beco...

A solar-aided coal-fired power plant realizes the integration of a fossil fuel (coal or gas) and clean energy (solar). In this paper, a conventional 600 MW coal-fired power plant and a 600 MW solar-aided coal-fired power plant have been taken as the study case to understand the merits of solar-aided power generation (SAPG) technology. The plants in the case study have been analyzed by using the...

This paper investigates the extent to which ‘advanced’ knowledge and technology is likely to play a role in reducing greenhouse gas (GHG) emission in future by looking at the role that advanced knowledge and technology played in the technological change process that reduced SO2 emissions under the US SO2 cap and trade program. It investigates the hypothesis that advanced knowledge and technolog...

An area of major concern in considering increased coal production and utilization is the health and safety of increased numbers of workers who mine, process, or utilize coal. Hazards related to mining activities in the past have been especially serious, resulting in many mine related accidental deaths, disabling injuries, and disability and death from chronic lung disease. Underground coal mine...
