A fossil fuel [a] is a carbon compound- or hydrocarbon-containing material [2] formed naturally in the Earth's crust from the buried remains of prehistoric organisms (animals, plants or planktons), a process that occurs within geological formations.
This involves synthesis of oil within the crust via catalysis by chemically reductive rocks. A proposed mechanism for the formation of inorganic hydrocarbons [36] is via natural analogs of the Fischer–Tropsch process known as the serpentinite mechanism or the serpentinite process. [21] [37] CH 4 + ½ O 2 → 2 H 2 + CO (2n+1) H 2 + nCO → C ...
Kerogen formation represents a halfway point between organic matter and fossil fuels: kerogen can be exposed to oxygen, oxidize and thus be lost, or it could be buried deeper inside the Earth's crust and be subjected to conditions which allow it to slowly transform into fossil fuels like petroleum.
Methods to produce hydrogen without the use of fossil fuels involve the process of water splitting, or splitting the water molecule (H 2 O) into its components oxygen and hydrogen. When the source of energy for water splitting is renewable or low-carbon, the hydrogen produced is sometimes referred to as green hydrogen .
Petroleum is a fossil fuel that can be drawn from beneath the Earth's surface. Reservoirs of petroleum are formed through the mixture of plants, algae, and sediments in shallow seas under high pressure. Petroleum is mostly recovered from oil drilling. Seismic surveys and other methods are used to locate oil reservoirs.
Coal homogenization – Process of mixing coal to reduce variance; Coal measures (stratigraphic unit) Health and environmental impact of the coal industry; Fluidized bed combustion – Technology used to burn solid fuels; Fossil fuel phase-out – Gradual reduction of the use and production of fossil fuels
Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N 2), carbon monoxide (CO), hydrogen (H 2), and carbon dioxide (CO 2).
Illustrating inputs and outputs of steam reforming of natural gas, a process to produce hydrogen and CO 2 greenhouse gas that may be captured with CCS. Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water.
