In the guide below, we briefly outline the differences and similarities between biomass vs biofuel vs bioenergy vs biogas.
We also indicate how they relate to one another.
Biomass
Biomass is organic material, and is considered to be ‘renewable’
It mainly comes from different types of plants, and also algae (although some reports indicate it can also come from animals)
Biomass is the material that all three of biofuel, bioenergy and biogas are derived from
A range of ‘bioproducts’ (commodities) are also derived from biomass
Biofuel
Biofuels are fuels derived from biomass
Biomass goes through a conversion process to become a refined biofuel product
Biofuels are commonly used for transportation in vehicles as fuel
Two common examples of biofuels are ethanol, and also biodiesel
Bioenergy (Biopower)
Bioenergy is also referred to as biopower
It is energy that is derived from biomass
Energy generation from biomass can produce heat, or electricity
There’s multiple ways to release the energy contained in bioenergy (which gets stored in biomass from the process of photosynthesis)
Biogas
Biogas is gas (mainly methane and carbon dixoide) captured from the anaerobic digestion of organic waste and organic matter
The gas is an energy source which can be used for heat or electricity (for use in engines, microturbines, and fuel cells)
But, there’s also liquid and solid components (called digestate) produced from the break down of organic matter (separate to the gas released) that can be used as a soil amendment
Biomass vs Bioenergy vs Biofuel vs Biogas – Similarities & Differences
Similarities
The similarities are that all three of bioenergy, biofuel and biogas are derived from biomass material
They are all considered to be ‘renewable’ in this regard too
Differences
The main differences are that:
– Biomass is the material used to produce the other three
i.e. these other three products are derived from biomass, and therefore rely on biomass
– Bioenergy, biofuels and biogas are all produced in different ways
As an example, biofuels require their own conversion process, whereas biogas is produced from anaerobic digestors
– Bioenergy, biofuels and biogas are used across different industries and for different applications
As an example, biofuels might be used much more heavily for transportation and vehicles, whilst bioenergy might mainly be used for heat or electricity generation
