What are biomasses and biofuels?
Biomass can be used to produce renewable electricity, thermal energy, or transportation fuels (biofuels). Biomass is defined as living or recently dead organisms and any byproducts of those organisms, plant or animal.
Is CNG a biofuel?
Like conventional natural gas, RNG can be used as a transportation fuel in the form of compressed natural gas (CNG) or liquefied natural gas (LNG). RNG qualifies as an advanced biofuel under the Renewable Fuel Standard.
What is biomass feedstock?
Biomass feedstocks include forest products wastes, agricultural residues, organic fractions of municipal solid wastes, paper, cardboard, plastic, food waste, green waste, and other waste. Biomass is a sustainable feedstock for chemicals and energy products. Biomass feedstocks are more evenly distributed in the world.
Is oil a biofuel?
Bioethanol is produced by the fermentation of carbohydrates produced in starch crops or sugar, while biodiesel is made from animal fats and vegetable oils. Crude oil, on the other hand, is a naturally occurring flammable liquid consisting of complex mixtures of hydrocarbons and other organic compounds.
Is coal a biofuel?
Biofuel is fuel derived from living matter called biomass (usually plant matter). Examples of biofuels include but are not limited to biodiesel, ethanol, and vegetable oil….Interactive graph.

| Coal and coal products | 162659.58 PJ |
| Natural gas | 137876.51 PJ |
| Biofuels and waste | 55442.21 PJ |
| Nuclear | 29592.91 PJ |
Which plants are used for biofuels?
Biofuels are renewable substitutes for fossil fuels that are mainly produced from crop plants such as corn, soybeans, wheat, and sugarcane. But animal fats and other byproducts, along with household food waste, can also be used to make biofuels.
What are feedstocks in oil and gas?
Feedstock is any hydrocarbon input to a process unit. This could be crude oil or any intermediate refining stream. When the term feedstock is used for the feed to the entire refinery, it typically means non-crude feedstocks such as VGO and blendstocks.
What are types of feedstocks?
Biomass Feedstocks as a Renewable Carbon Source
- Agricultural residues (e.g., corn stover)
- Algae.
- Dedicated energy crops (e.g., switchgrass, miscanthus, energy cane, sweet sorghum, high biomass sorghum, hybrid poplars, and shrub willows)
- Forestry residues (e.g., logging residues and forest thinning)
What is the most popular biofuel?
Ethanol fuel
Ethanol fuel is the most common biofuel worldwide, particularly in Brazil.
How is biofuel made?
Biodiesel is produced from vegetable oils, yellow grease, used cooking oils, or animal fats. The fuel is produced by transesterification—a process that converts fats and oils into biodiesel and glycerin (a coproduct).
