  • Legal lookout: competing coal ash proposals

    Depending upon comments the EPA gathers, industry may have to or not have to close out their coal ash containment ponds within five years. On May 4, 2010, EPA issued its long-awaited proposal to manage coal ash – the byproduct of burning coal to generate power. The agency proposed two quite different approaches for regulating coal ash, somewhat to the consternation of critics, who had hoped ...

  • Difficult Complex Decisions For Coal-fired Power Plant Operators

    Changing fuel prices, government regulations and technology all combine to make decision making difficult for operators and developers of coal-fired power generation facilities around the world. Power plant designers in developing countries face new local environmental regulations plus additional requirements stipulated by lenders such as the World Bank. In the developed world, the regulations ...

  • EPA targets electric utilities - the agency steps up efforts to manage coal ash damage

    Approximately 5.4 million cubic yards, or 1.1 billion gallons, of coal ash from the Tennessee Valley Authority (TVA) plant near Knoxville, Tenn., in December 2008 flooded some 300 acres of land, damaging property, polluting waterways, and killing fish. TVA will likely spend more than $500 million and perhaps as much as $1 billion dollars on the cleanup, says the U.S. Environmental Protection ...

  • Clean energy technologies will create waste

    The birth of mitigating our dependency on oil and coal is here. We are rapidly developing energy saving and renewable-energy solutions that are about to transform our lives for the better, bringing a new era of limiting our dependency on fossil fuel, and creating less wastes when generating electricity. But inevitably through this period we will create other wastes, some hazardous. These changes ...

  • Energy recovery from waste by use of fluidised-bed technology

    Revolving type fluidised-bed technology, developed by Ebara Corp., is installed in more than 100 facilities worldwide. The technology is applied for waste, coal and in situations where a conventional fluidized bed is difficult to use. Waste and/or coal can be treated and valuable energy can be recovered from a non-renewable source. This paper describes the application of the revolving fluidised ...

  • Assessing and improving the efficiencies of a steam power plant using exergy analysis. Part 1: assessment

    Energy and exergy analyses are used to examine the performance of a coal-fired steam power plant and to identify and evaluate possible modifications to improve the efficiency of the plant. The exergy analysis provides a detailed breakdown of the exergy losses (including waste exergy emissions and internal irreversibilities) for the overall plant and its components. The results show that ...

  • Nuclear power economics and prospects in the USA

    This paper addresses three questions concerning the economics of and prospects for nuclear power in the USA: (1) What is the long-term economic future of nuclear energy? (2) Is the inability to resolve the nuclear waste issue a factor that will limit new nuclear plant development? (3) Are the new designs for nuclear plants an advance over current designs? With respect to the first question, we ...

  • Innovative Solutions for the Power Generation Industry

    The global demand for power continues to increase, especially in fast growing areas of Asia including China, India and the Middle East. The environmental regulations on these power generation companies are also becoming more stringent. Power generation companies need smart, sustainable solutions to meet the specific water quality requirements that will ensure consistent process and power ...

  • The development of biomass gasification technology towards market penetration in China

    Biomass is the second most frequently used fuel, after coal, in China, which accounts for 20% of primary energy consumption. Though the main usage of biomass is for household cooking, the newly developed biomass gasification technology, especially the circulating fluidized bed gasification (CFBG) technology, has laid the foundations for allowing biomass gasification industry penetration into the ...

  • Increasing the use of recovered mineral components in cement or concrete

    Section 6017(a) of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users, P.L. 109-59, Aug. 10, 2005 (SAFETEA-LU), directs the U.S. Environmental Protection Agency (EPA or the Agency) to, “…conduct a study to determine the extent to which procurement requirements, when fully implemented…may realize energy savings and environmental benefits attainable with ...

  • Efficiency is cheap, but will it sell?

    Expect to see this number a lot in energy discussions over the next few years: 2.5 cents/kWh. It is the average cost of energy efficiency, a figure pegged this week in a new report by the American Council for an Energy Efficient Economy. This number is big news because it is so small. As a resource, energy efficiency beats out all conventional power sources on price. Moreover, it’s a price that ...

  • The natural gas revolution: Good or bad for energy efficiency?

    If there were an equivalent in the energy industry to Time Magazine’s Person of the Year, natural gas would be this year’s winner. The dramatic rise in natural gas supply, and fall in price, has reconfigured the energy scene in the United States, suddenly creating a bounty of domestic energy, driving down wholesale power prices and speeding retirement of polluting coal-fired plants. ...

  • Q&A: The world’s eyes turn to Minnesota on district energy

  • The future of nuclear power worldwide

    Energy production from fossil fuels, mainly natural gas and coal, contributes significantly to global warming through large-scale greenhouse gas emissions, mainly of hundreds of billions of tonnes of carbon in the form of carbon dioxide. At least for the next few decades, one of the realistic options for reducing carbon dioxide emissions from energy production could be the increasing use of ...

  • The Energy Game is Rigged: Fossil Fuel Subsidies Topped $620 Billion in 2011

    The energy game is rigged in favor of fossil fuels because we omit the environmental and health costs of burning coal, oil, and natural gas from their prices. Subsidies manipulate the game even further. According to conservative estimates from the Global Subsidies Initiative and the International Energy Agency (IEA), governments around the world spent more than $620 billion to subsidize fossil ...
