Carbon-based fuel is any fuel principally from the oxidation or burning of carbon.Carbon-based fuels are of two main kinds, biofuels and fossil fuels.Whereas biofuels are derived from recent-growth organic matter [1] and are typically harvested, as with logging of forests and cutting of corn, fossil fuels are of prehistoric origin [2] and are extracted from the ground, the principal fossil ...
Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO 2 ) as a feedstock . Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels , which are made by chemically hydrogenating carbon dioxide, and biofuels ...
Another option is the use of alternative fuel composition in conventional fossil fuel-based vehicles, making them function partially on renewable energy sources. Other approaches include personal rapid transit , a public transportation concept that offers automated, on-demand, non-stop transportation on a network of specially built guideways.
Porsche is investing $75 million in Chilean company HIF, which has developed a method of creating a synthetic liquid fuel that can be used in any gasoline-burning engine and is also almost carbon ...
The transportation industry, a longtime and significant contributor to CO2 emissions, has reached a major milestone: In 2023, carbon emissions on new cars hit a record low of 319 grams of CO2 per ...
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.

At about 7.5 lb/USgal (900 g/L) this is about 38 billion USgallons (144 billion L). Currently vegetable oil is mostly used in food and some industrial uses with a small percentage used as fuel. The major fuel usage is by conversion to biodiesel with about 3 billion US gallons (11,000,000 m 3) in 2009. [23]
Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide [1] or biomass, and biodiesel), Hydrogen fuel (when produced with renewable processes), and fully synthetic fuel (also known as electrofuel) produced from ambient carbon dioxide and water.
