  • Trump Touts 'Clean Coal': What Is It, Really? | Live Science

    Carbon capture. Trump's confusing use of "clean coal" is par for the course; the term itself is fairly vague and has no set definition, said Shiela Medina, the associate director of development ...

  • Pre-Combustion Carbon Capture Research | Department of Energy

    Pre-combustion capture refers to removing CO 2 from fossil fuels before combustion is completed. For example, in gasification processes a feedstock (such as coal) is partially oxidized in steam and oxygen/air under high temperature and pressure to form synthesis gas.

  • Petra Nova is one of two carbon capture and sequestration ...

    Petra Nova's carbon-capture system is designed to capture about 90% of the carbon dioxide (CO2) emitted from the flue gas slipstream, or about 33% of the total emissions from Unit 8. The post-combustion process is energy intensive and requires a dedicated natural gas unit to accommodate the energy requirements of the carbon-capture process.

  • What is coal? | World Coal Association

    Coal formation. All living plants store solar energy through a process known as photosynthesis. When plants die, this energy is usually released as the plants decay. Under conditions favourable to coal formation, the decaying process is interrupted, preventing the release of the stored solar energy. The energy is locked into the coal.

  • Capture - Coal 21

    Post-combustion capture separates CO 2 from the gas stream produced after coal or other fossil fuels are used to generate electricity. It is currently the most advanced capture technology and can remove up to 90 per cent of emitted CO 2.. The most common process for post-combustion capture uses liquid chemicals called amines.

  • Carbon Capture R&D | Department of Energy

    The Carbon Capture Program consists of two core research Technology Areas: Post-Combustion Capture; Post-combustion capture is primarily applicable to fossil fuel based systems such as conventional pulverized coal (PC)-fired power plants, where the fuel is burned with air in a boiler to produce steam that drives a turbine/generator to produce electricity.

    Dec 07, 2009 · Process could capture carbon more cheaply. Implementing such a system at a full-scale power plant has two main challenges, says David Thimsen, a senior project manager for advanced coal .

  • Integrated gasification combined cycle - Wikipedia

    An integrated gasification combined cycle (IGCC) is a technology that uses a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the power generation cycle. Some of these pollutants, such as sulfur, can be turned into re-usable byproducts through the Claus process.
