  2. Alternative fuel - Wikipedia

    en.wikipedia.org/wiki/Alternative_fuel

    Alternative fuels, also known as non-conventional and advanced fuels, [1] are fuels derived from sources other than petroleum. [2] Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity. [3]

  3. Substitutional fuel - Wikipedia

    en.wikipedia.org/wiki/Substitutional_fuel

    Conventional fuels include fossil fuels such as coal, oil (including fuel oil, diesel fuel, and gasoline), and natural gas. [2] [circular reference] Fossil fuels have many negative externalities, most notably air pollution and contributing to climate change. Both the extraction and combustion of conventional fuels have negative externalities.

  4. Substitute natural gas - Wikipedia

    en.wikipedia.org/wiki/Substitute_natural_gas

    Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH 4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems.

  5. Unconventional (oil and gas) reservoir - Wikipedia

    en.wikipedia.org/wiki/Unconventional_(oil_and...

    When pressure differences are relatively high, oil and gas rise to the well bore naturally through buoyancy. [c] Where the pressures are low, flow can be assisted with pumps (e.g. nodding donkeys). [2] Schematic cross-section of general types of oil and gas resources featuring unconventional as well as conventional reservoirs

  6. Using Natural Gas As Alternative Fuels ー Net-Zero Carbon - AOL

    The search for alternatives to diesel fuel has been ongoing, leading people to turn to options like hydrogen, battery fuel cells, and the subject of this episode of Net-Zero Carbon: liquified ...

  7. Compressed natural gas - Wikipedia

    en.wikipedia.org/wiki/Compressed_natural_gas

    Compressed natural gas vehicles require a greater amount of space for fuel storage than conventional petrol-powered vehicles. Since it is a compressed gas, rather than a liquid like petrol, CNG takes up more space for each GGE (petrol gallon equivalent). However, the cylinders used to store the CNG take up space in the trunk of a car or bed of ...

  8. Syngas - Wikipedia

    en.wikipedia.org/wiki/Syngas

    Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, [1] in various ratios. The gas often contains some carbon dioxide and methane . It is principally used for producing ammonia or methanol .

  9. Synthetic fuel - Wikipedia

    en.wikipedia.org/wiki/Synthetic_fuel

    Side-by-side comparison of FT synthetic fuel and conventional fuel. The synthetic fuel is extremely clear because of the near-total absence of sulfur and aromatics. Synthetic fuel or synfuel is a liquid fuel , or sometimes gaseous fuel , obtained from syngas , a mixture of carbon monoxide and hydrogen , in which the syngas was derived from ...
