Biomass Energy Glossary
Navigate the complex terminology of bioenergy and sustainability. From BECCS to Torrefaction, find clear definitions for key industry terms.
A
Anaerobic Digestion
A biochemical process where microorganisms break down organic matter in the absence of oxygen, producing biogas (mostly methane) and a nutrient-rich digestate fertilizer.
B
BECCS
Bioenergy with Carbon Capture and Storage. A technology that combines bioenergy production with the capture and permanent storage of the carbon dioxide produced, potentially achieving negative emissions.
Bioenergy
Renewable energy produced from biological sources, including forest residues, agricultural crops, and organic waste.
Biofuel
A fuel derived directly from living or recently living organic matter, such as ethanol from corn or biodiesel from vegetable oils.
Biogas
A mixture of gases, primarily methane and carbon dioxide, produced by the breakdown of organic matter in the absence of oxygen.
Biomass
Organic material derived from plants and animals, which contains stored energy from the sun and can be used as fuel.
Black Liquor
The waste product from the kraft process when digesting pulpwood into paper pulp, containing wood residues and chemicals, often used as an energy source in paper mills.
C
Carbon Neutrality
The state of achieving net-zero carbon dioxide emissions by balancing carbon emissions with carbon removal or sequestration.
Carbon Sequestration
The long-term storage of carbon in plants, soils, geologic formations, or the ocean, helping to mitigate global warming.
Cascading Use
The principle of prioritizing the use of biomass for high-value materials (like timber or chemicals) before using it for energy recovery at the end of its life cycle.
Cogeneration (CHP)
Combined Heat and Power. The simultaneous generation of electricity and useful heat from the same energy source, significantly increasing overall efficiency.
E
Energy Crop
A plant grown specifically for use as a fuel or for conversion into biofuels, such as switchgrass, willow, or miscanthus.
F
Feedstock
The raw material used to supply or fuel an industrial process, such as wood chips, agricultural residues, or food waste used for energy production.
G
Gasification
A thermochemical process that converts organic materials into a combustible gas mixture called syngas by heating it with a controlled amount of oxygen.
I
Indirect Land Use Change (ILUC)
The unintended consequence of releasing more carbon emissions due to land-use changes elsewhere in the world induced by the demand for biofuel crops.
L
Life Cycle Assessment (LCA)
A systematic analysis of the environmental impacts of a product or process throughout its entire life cycle, from raw material extraction to disposal.
Lignocellulosic Biomass
Plant dry matter composed mainly of cellulose, hemicellulose, and lignin, which forms the structural part of woody plants and grasses.
P
Pelletization
The process of compressing biomass into small, dense pellets to improve its energy density, handling, and transport efficiency.
Pyrolysis
The thermal decomposition of organic material at high temperatures in the absence of oxygen, producing bio-char, bio-oil, and syngas.
S
Sustainable Forest Management
The management of forests according to principles that ensure they remain healthy, productive, and biodiverse while meeting current and future social, economic, and ecological needs.
Syngas
Short for synthesis gas, a fuel gas mixture consisting primarily of hydrogen and carbon monoxide, produced through gasification or pyrolysis.
T
Torrefaction
A mild form of pyrolysis that 'roasts' biomass at relatively low temperatures to improve its fuel properties, making it more brittle and energy-dense.
