Biomethane (RNG)

Biomethane (Renewable Natural Gas) is a source of methane derived from the purification of biogas, which has the same characteristics as natural gas. The so-called upgrading process opens a whole new world of biogas valorization. Biomethane offers new end consumers a variety of ways to green their energy sources - it can be injected in the natural gas grid or be used to fuel vehicles.

Why should you invest into biomethane now?


  • Higher efficiency than electricity valorization
  • Less dependent from subsidized feed in tariffs
  • Technical feasibility proven for more than a decade
  • Wide range of biogas upgrading technologies available
  • Overall increase in government incentives supporting biomethane
  • Worldwide growing market for biomethane
  • Extended independency from fossil fuel (imports)
  • Utilization of existing infrastructure & gas filling stations
  • Energy storage capability
  • Generation of sustainable employment in rural areas

How we produce biomethane.

With our unique PowerRing digester, we can produce biomethane from a wide range of different feedstocks. Due to our optimal mixing technology, the feedstock is used in the most efficient way and BIOGEST plants are showing higher degradation rates than classic biomethane plants.

The compact design and concrete roof assure an insulation of the whole digester which leads to minimized thermal energy demand, thus reducing the amount of gas consumed to heat the digester. This significant difference directly translates to an increased amount of injected biomethane which results in revenues for the project.

BIOGEST has worked with many different gas upgrading manufacturers and has already installed many biogas plants worldwide, including several biomethane plants. We cater to the needs of each specific project by evaluating the different technology options with each clients.
