A fossil fuel [a] is a carbon compound - or hydrocarbon -containing material such as coal, oil, and natural gas, [2] formed naturally in the Earth's crust from the remains of prehistoric organisms (animals, plants and planktons ), a process that occurs within geological formations. Reservoirs of such compound mixtures can be extracted and ...
Hydrocarbon. Ball-and-stick model of the methane molecule, CH 4. Methane is part of a homologous series known as the alkanes, which contain single bonds only. In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [1] : 620 Hydrocarbons are examples of group 14 hydrides.
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.
The team also found that the heat waves that baked much of the globe in July 2023 would have been “virtually impossible” without the planetary heating caused by burning fossil fuels.
Chemical fuels are substances that release energy by reacting with substances around them, most notably by the process of combustion . Chemical fuels are divided in two ways. First, by their physical properties, as a solid, liquid or gas. Secondly, on the basis of their occurrence: primary (natural fuel) and secondary (artificial fuel).
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10] The vast majority of biomass used for bioenergy ...
Methanol may be made from fossil fuels or renewable resources, in particular natural gas and coal, or biomass respectively. In the case of the latter, it can be synthesized from CO 2 (carbon dioxide) and hydrogen. [3] The vast majority of methanol produced globally is currently made with gas and coal. [4]
When heated to the right temperatures in the earth's crust, (oil window c. 50–150 °C, gas window c. 150–200 °C, both depending on how quickly the source rock is heated) some types of kerogen release crude oil or natural gas, collectively known as hydrocarbons (fossil fuels).
