Methane (CH4) and carbon dioxide (CO2)
What is the process by which biogas is produced?
Anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor
How can biogas be used as a fuel?
It can be used in fuel cells, for heating purposes such as in cooking, and in a gas engine to convert the energy into electricity and heat

Study Notes
Biogas Composition
- Biogas primarily consists of methane (50-70%) and carbon dioxide (30-40%) with small amounts of other gases.
Biogas Production
- Biogas is produced through anaerobic digestion, a natural process in which microorganisms break down organic matter in the absence of oxygen.
Biogas as a Fuel
- Biogas can be used as a renewable energy source for heat, electricity, and transportation fuel.
- It can be used directly as a substitute for fossil fuels in power generation, industrial processes, and vehicle fuel.
- Biogas can be upgraded to biomethane, a pipeline-quality natural gas equivalent, for injection into gas grids.
Biogas in the United Kingdom
- The UK has a significant potential for biogas production from agricultural, municipal, and industrial organic waste.
- Biogas could contribute significantly to the UK's renewable energy targets and reduce greenhouse gas emissions.
Renewable Resource
- Biogas is considered a renewable resource because it is produced from organic waste, which is replenished naturally.
- The biogas production process is carbon neutral, as the amount of carbon dioxide emitted during energy generation is equal to the amount of carbon dioxide absorbed by the organic matter during its growth.
