Biomass vs. Biogas — What's the Difference?

By Tayyaba Rehman — Updated on September 20, 2023
Biomass refers to organic material from plants and animals that can be used as a renewable energy source. Biogas is a specific type of gas produced by the anaerobic decomposition of biomass and is commonly used for heating and electricity.

Key Differences

Biomass is a broad category of organic material derived from living or recently living organisms, including wood, agricultural residues, and animal waste. Biogas, on the other hand, is a specific gaseous product resulting from the breakdown of biomass in an environment without oxygen (anaerobic). Biomass serves as the raw material, while biogas is one of the end products.
Biomass can be converted into various forms of energy or material products. These can include solid fuels, liquid fuels, and even electricity through combustion or biochemical processes. Biogas is a subset of the energy products that can be produced from biomass, generally formed through anaerobic digestion or fermentation. Biomass has a wider range of applications, whereas biogas is mainly used for heating and electricity generation.
Biomass is often directly burned for heat or converted into pellets, biodiesel, or ethanol. Biogas is typically collected and stored for use as a fuel. In biomass, the energy is stored in the form of chemical bonds in the organic material itself. In biogas, the energy is stored in the form of methane gas, which can be burned to release that energy.
In summary, biomass is the broader term encompassing all types of organic matter that can be used for a range of energy applications. Biogas is a more specific term, describing the gas produced from the anaerobic decomposition of biomass. While biomass offers multiple avenues for energy conversion, biogas is a singular form of renewable energy derived from biomass.

Biomass

Biomass is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops and waste from forests, yards, or farms.

Biogas

Biogas is the mixture of gases produced by organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.

Biomass

The total mass of living matter within a given unit of environmental area.

Biogas

A mixture of methane and carbon dioxide produced by bacterial degradation of organic matter and used as a fuel.

Biomass

Plant or animal material, such as forestry byproducts or agricultural waste, that is used as a fuel or energy source.

Biogas

A mixture of methane and carbon dioxide, produced by anaerobic digestion of organic waste matter, used as a fuel

Biomass

(biology)

Biomass

The total mass of a living thing or a part thereof (such as a cell).

Biomass

The total mass of all, or a specified category of, living things within a specific area, habitat, etc.

Biomass

Organic matter from living things which were recently alive (especially vegetation) used as a fuel or source of energy, especially if cultivated for that purpose; also, fuel produced from such organic matter; biofuel.

Biomass

Plant materials and animal waste used as fuel

Biomass

The total mass of living matter in a given unit area
