Biofuel Basics - Department of Energy
Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called "biofuels," to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology.
Ethanol explained - U.S. Energy Information Administration (EIA)
In the United States, nearly all fuel ethanol is produced from corn kernel starch, which is considered a conventional biofuel under the U.S. Renewable Fuel Standard Program (RFS). Ethanol has other potential sources aside from fermentating grain starch and sugars.
Biofuels explained Ethanol - U.S. Energy Information Administration …
In 2022, U.S. fuel ethanol production (as measured by renewable fuels and oxygenate plant net production of fuel ethanol) was about 15.4 billion gallons (about 0.4 billion barrels). Fuel ethanol production fell in 2020, mainly because lower overall gasoline demand reduced the demand for ethanol blending into motor gasoline.
Ethanol vs. Petroleum-Based Fuel Carbon Emissions
Jun 23, 2022 · Biofuels have been proven to emit significantly lower greenhouse gas (GHG) emissions than petroleum-based fuels, and recent scientific studies indicate that net-zero emission biofuels are not only possible, but achievable. Corn ethanol and other biofuels.
Biofuels Factsheet | Center for Sustainable Systems
Ethanol, an alcohol blended with gasoline for vehicle fuel, is the most produced (82%) and used (75%) biofuel in the U.S. 2; The U.S. and Brazil produced 80% of the world’s ethanol in 2022. 3 94% of U.S. ethanol is derived from corn 4, while Brazil uses sugarcane as feedstock 4.
Biofuels, from ethanol to biodiesel, facts and information
Jul 15, 2019 · Much of the gasoline in the United States contains one of the most common biofuels: ethanol. Made by fermenting the sugars from plants such as corn or sugarcane, ethanol contains oxygen that...
Bioenergy Basics - Department of Energy
Biomass is one type of renewable resource that can be converted into liquid fuels—known as biofuels—for transportation. Biofuels include cellulosic ethanol, biodiesel, and renewable hydrocarbon "drop-in" fuels. The two most common types of …
What are the Pros and Cons of Ethanol Biofuel?
Jul 23, 2019 · Biofuels like ethanol might help fight climate change. But they can contribute to food insecurity and greenhouse gases in ways that might surprise you.
Ethanol | Transportation | 2024 | ATB | NREL
Ethanol. Ethanol is a renewable fuel. Made from biomass (i.e., a variety of plant materials), ethanol is used in 98% of U.S. gasoline. ... The biogenic carbon in a biofuel such as ethanol is considered carbon-neutral in the R&D GREET model because the biogenic carbon is assumed to be sourced from the atmosphere during biomass growth.
Biofuels Basics | NREL
The two most common types of biofuels in use today are ethanol and biodiesel. NREL researchers are developing technology to produce ethanol from the fibrous material (cellulose and hemicellulose) in corn stalks and husks or other agricultural or forestry residues.
