  2. Emission intensity - Wikipedia

    en.wikipedia.org/wiki/Emission_intensity

    An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).

  3. Supercritical carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Supercritical_carbon_dioxide

    Supercritical carbon dioxide. 2) is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Carbon dioxide usually behaves as a gas in air at standard temperature and pressure (STP), or as a solid called dry ice when cooled and/or pressurised sufficiently. If the temperature and pressure are ...

  4. Carbon sequestration - Wikipedia

    en.wikipedia.org/wiki/Carbon_sequestration

    Carbon sequestration is the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [3] Biologic carbon sequestration is a naturally ...

  5. Transcritical cycle - Wikipedia

    en.wikipedia.org/wiki/Transcritical_cycle

    v. t. e. A transcritical cycle is a closed thermodynamic cycle where the working fluid goes through both subcritical and supercritical states. In particular, for power cycles the working fluid is kept in the liquid region during the compression phase and in vapour and/or supercritical conditions during the expansion phase.

  6. Regulation of greenhouse gases under the Clean Air Act

    en.wikipedia.org/wiki/Regulation_of_greenhouse...

    These six greenhouse gases are: carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF 6). These greenhouse gases in the atmosphere constitute the "air pollution" that threatens both public health and welfare. 2) The Cause or Contribute Finding, in which the ...

  7. Gas engine - Wikipedia

    en.wikipedia.org/wiki/Gas_engine

    A gas engine is an internal combustion engine that runs on a fuel gas (a gaseous fuel), such as coal gas, producer gas, biogas, landfill gas, natural gas or hydrogen. In the United Kingdom and British English -speaking countries, the term is unambiguous. In the United States, due to the widespread use of "gas" as an abbreviation for gasoline ...

  9. Transient climate response to cumulative carbon emissions

    en.wikipedia.org/wiki/Transient_climate_response...

    The transient climate response to cumulative emissions of carbon dioxide (TCRE) is the ratio of the globally averaged surface temperature change per unit carbon dioxide (CO 2) emitted. [1][2] [3] [4] As emitted CO 2 may stay in the atmosphere for thousands of years, this response is the amount that the global temperature changes per the net ...
