  • Inquiry Into Coal Seam Gas

    Poorly planned or managed coal seam gas (CSG) exploration or extraction activities pose considerable risks to both groundwater and surface water systems. Key water quality issues, from my own perspective, are listed below. Specific issues may be of greater or lesser significance for particular projects, but all of these issues should be thoroughly and transparently assessed for all proposed ...

  • Is `clean` coal possible?

    VANCOUVER, April 18, 2007 (GLOBE-Net) - Coal is the world’s most commonly used fuel to produce electrical energy, and will continue as such for some time. Yet it is one of the ’dirtiest’ of all fossil fuels. It is a major source of toxic air pollutants and the leading source of energy-related greenhouse gas emissions. Many believe ’clean coal’ technologies will improve the energy efficiency of ...

  • Coal-to-liquid fuels poised for a comeback

    Converting coal into liquid fuels is known to be more costly than current energy technologies, both in terms of production costs and the amount of greenhouse gases the process emits. Production of coal-to-liquid fuel, or CTL, has a large carbon footprint, releasing more than twice the lifecycle greenhouse gases of conventional petroleum fuels. However, with the rise in energy prices that began ...

  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • Coal Bed Methane - A Global Market Scenario

    Coal Bed Methane (CBM) is a type of natural gas that is commonly extracted from coal beds located at depths between 300 to 1000 metres. This gas is an odorless, colorless mixture of a variety of gases, but with major share of methane – even upto 95% in many cases.  Browse: Coal Bed Methane ...


  • Low-permeability liner solution for coal-ash by-products

    PROJECT: TVA Kingston Gypsum Pond Expansion LOCATION: Harriman, Tennessee PRODUCTS: BENTOMAT® 600CL BENTOMAT® CL EASY ROLLER™ Deployment System BACKGROUND: As part of its emissions control at the Kingston Fossil Plant, flue gas desulfurization is performed, which creates as a by-product a synthetic ...

  • Analysis of U.S. coal plant retirements case study

    In 2010, MJB&A completed a report for a major natural gas transmission company of coal-fired electricity generating units (EGUs) in several different geographic regions and their potential for retirement and/or to repower with natural gas. This analysis developed an indicative model of future coal-fired power plant repowerings and retirements based on a range of operational and market ...

  • Coal and its future are fueling conflicts around the globe

    "Coal Wars: The Future of Energy and the Fate of the Planet" (Palgrave Macmillan), by Richard Martin Fierce conflicts over coal are taking place around the globe, but author Richard Martin says the decline and ultimate demise of the fuel that powered the Industrial Revolution is inevitable and cannot be reversed. What he cannot predict, he says, is whether the transition to energy sources that ...

  • The role of coal technologies to support responsible economic growth

    The Asian Pacific region is home to the fastest-growing economies in the world. These economies are expected to double gross domestic product (GDP) in the next decade, and coal will play a major role as the primary energy source for electric power. The tremendous projected financial burden associated with the installation of new, coal-fired electric power facilities to fuel this unprecedented ...

  • Preliminary research of health and environmental impacts and greenhouse gas emission from coal-fired power and nuclear power chains in China

    The present paper treats health, environmental impacts and greenhouse gas emission resulting from both the coal-fired power chain and nuclear power chain in China. The nuclear power chain resulted in adverse health impacts 3-4 orders of magnitude lower than those from the coal-fired power chain, also radiological emissions were 1-2 orders of magnitude lower. Estimated greenhouse gas emission ...

  • China may be ready to kick coal habit

    There are still doubts. The statistics might be proved wrong. But it looks as if China might be starting to wean itself off its coal consumption habit. China produces and consumes nearly as much coal as the rest of the world combined. Coal, the most polluting of all energy sources, has powered the growth of China’s flyaway economy. But as incomes have risen, so has pollution. The country is ...

  • Photosynthetic pigment concentrations, gas exchange and vegetative growth for selected monocots and dicots treated with two contrasting coal fly ashes

    There is uncertainty as to the rates of coal fly ash needed for optimum physiological processes and growth. In the current study we tested the hypothesis that photosynthetic pigments concentrations and CO2 assimilation (A) are more sensitive than dry weights in plants grown on media amended with coal fly ash. We applied the Terrestrial Plant Growth Test (Guideline 208) protocols of the ...

  • New coal report underscores the urgent need for global clean energy development

    The latest International Energy Agency’s (IEA) Medium-Term Coal Market Report 2012 re-confirms the dangerous path the world is on–a path of increasing dependence on coal, which carries serious environmental risks for people and the planet. According to ...

  • Fast and reliable safety surveillance in coal silos – Case Study

    CO Monitoring in Coal Silos Coal Silos are widely used nearby mining facilities or as intermediate storage containers at steel or cement plants. A major threat in running this facilities is the random occurance of partial self-ignition of the coal. This leads to elevated CO concentrations inside the headspace of the silo. This self-ignition is hardly to predict, since its occurance ...

  • Fact Sheet: U.S. electricity markets increasingly favor alternatives to coal

    The U.S. electric power system is gradually shifting toward cleaner forms of generation. One sign of this transition is the declining use of coal for electric power production. In 2011, use of coal for U.S. power generation dropped to its lowest level in more than a decade, according to the federal government’s independent U.S. Energy Information Administration (EIA). In fact, the EIA ...
