  2. Refuse-derived fuel - Wikipedia

    en.wikipedia.org/wiki/Refuse-derived_fuel

    Continuous use of various waste-derived alternative fuels then followed in the mid-1980s with “Brennstoff aus Müll“ (BRAM) – fuel from waste – in the Westphalian cement industry in Germany. At that time the thought of cost reduction through replacement of fossil fuels was the priority as considerable competition pressure weighed down ...

  3. 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]

  4. Solid fuel - Wikipedia

    en.wikipedia.org/wiki/Solid_fuel

    Solid fuels have been used throughout human history to create fire [2] and solid fuel is still in widespread use throughout the world in the present day. [3] [4] Solid fuel from biomass is regarded as a renewable energy source which can contribute to climate change mitigation efforts. Solid fuel from fossil fuels (i.e. coal) is not a renewable ...

  5. Fossil fuel - Wikipedia

    en.wikipedia.org/wiki/Fossil_fuel

    The origin of fossil fuels is the anaerobic decomposition of buried dead organisms. The conversion from these organic materials to high-carbon fossil fuels typically requires a geological process of millions of years. [4] Due to the length of time it takes nature to form them, fossil fuels are considered non-renewable resources.

  6. Syngas - Wikipedia

    en.wikipedia.org/wiki/Syngas

    Chemical uses include the production of methanol which is a precursor to acetic acid and many acetates; liquid fuels and lubricants via the Fischer–Tropsch process and previously the Mobil methanol to gasoline process; ammonia via the Haber process, which converts atmospheric nitrogen (N 2) into ammonia which is used as a fertilizer; and oxo ...

  7. Motor fuel - Wikipedia

    en.wikipedia.org/wiki/Motor_fuel

    Currently, the majority of motor vehicles worldwide are propelled by internal combustion engines powered by petroleum-based fossil fuels such as gasoline, diesel or autogas. Other fuel types include ethanol, biodiesel, biogasoline, propane, compressed natural gas (CNG) and hydrogen (either using fuel cells or hydrogen combustion).

  8. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    If the combustion of carbon-neutral fuels is subject to carbon capture at the flue, they result in net-negative carbon dioxide emission and may thus constitute a form of greenhouse gas remediation. Negative emissions are widely considered an indispensable component of efforts to limit global warming, although negative emissions technologies are ...

  9. Coal - Wikipedia

    en.wikipedia.org/wiki/Coal

    The IPCC considers fossil fuels to be unabated if they are "produced and used without interventions that substantially reduce the amount of GHG emitted throughout the life-cycle; for example, capturing 90% or more from power plants." [175] [176]
