Biomass explained - U.S. Energy Information Administration …
网页2024年7月30日 · Biomass is renewable organic material that comes from plants and animals. Biomass can be burned directly for heat or converted to liquid and gaseous fuels through various processes. Biomass was the largest source of total annual U.S. energy consumption until the mid-1800s.
Biomass Energy - National Geographic Society
网页2023年10月19日 · People have used biomass energy—energy from living things—since the earliest homonids first made wood fires for cooking or keeping warm. Today, biomass is used to fuel electric generators and other machinery.
What is Biomass? - Energy Theory
网页2023年11月17日 · Biomass refers to renewable organic matter derived from plants and animals, containing stored chemical energy from the sun, generated through photosynthesis. It can be directly combusted for heat or transformed into liquid and gaseous fuels through various processes.
Biomass (energy) - Wikipedia
网页Biomass pyrolysis produces fuels such as bio-oil, charcoal, methane, and hydrogen. Hydrotreating is used to process bio-oil (produced by fast pyrolysis) with hydrogen under elevated temperatures and pressures in the presence of a catalyst to produce renewable diesel, renewable gasoline, and renewable jet fuel.
Bioenergy Basics - Department of Energy
网页Biopower technologies convert renewable biomass fuels into heat and electricity using processes like those used with fossil fuels. There are three ways to harvest the energy stored in biomass to produce biopower: burning, bacterial decay, and conversion to …
Definition, Renewable Energy, Types, & Pros and Cons - Britannica
网页2024年9月6日 · Biofuel is a renewable energy source that is derived from plant, algal, or animal biomass. Biofuel is advocated as a cost-effective and environmentally benign alternative to petroleum and other fossil fuels.
Biomass - Understand Energy Learning Hub
网页2023年2月1日 · Biomass can be burned directly for heat or converted to liquid and gaseous fuels through various processes. Liquid biofuels and biogas are energy carriers, or currencies, that are easier to use, transport, and store.
Biofuel Basics - Department of Energy
网页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.
Biomass Energy Basics | NREL
网页Biomass energy supports U.S. agricultural and forest-product industries. The main biomass feedstocks for power are paper mill residue, lumber mill scrap, and municipal waste. For biomass fuels, the most common feedstocks used today are corn grain (for ethanol) and soybeans (for biodiesel).
网页Bioenergy, or energy derived from biomass, is a sustainable alternative to fossil fuels because it can be produced from renewable sources, such as plants and waste, that can be continuously replenished.
