What is biomethane?


Biogas is made by breaking down(digesting) manure, agricultural biomass,sewage water or material from landfill sites. In general biogas is applied as fuel in CHPs (combined heat and power units) to generate electricity and heat. However, often the heat cannot be used or is hardly used, resulting in a loss of 40-50% of the energy in the biogas.

Biogas can also be converted into biomethane. Biomethane is renewable natural gas. It is fully interchangeable with natural gas and can be fed into the natural gas grid. Thus, less fossil natural gas is required and less CO2 is emitted. When converting biogas to biomethane only 10% of the energy is used in the process, which means 90% of the energy in the biogas is available for consumption.


Advantages of biomethane
  • Biomethane is easy to market as the demand is high,
  • Biomethane can be stored, unlike green electricity,
  • Energy efficiency is high compared to green electricity,
  • No time-of-day tariffs, enabling all round production,
  • Suitable as transport fuel.
