Biomethane

Biomethane, or biogas, is a 100% renewable gas derived from organic matter. A true driver of the energy transition, it helps reduce CO₂ emissions while offering a local and sustainable alternative to fossil gas.

ENGIE had already been active internationally in the field of biomethane development for some time, and reached a new milestone in 2024 with the acquisition of its first production unit on Belgian soil: Biogas Bree. This facility already supplies nearly 6,000 households with biomethane — also called green gas!

With this acquisition, ENGIE reaffirms its ambition: to produce 10 terawatt-hours of biomethane per year in Europe by 2030. A local and renewable energy, essential for building a decarbonized society. Biomethane strengthens the reliability of the energy system, reduces our dependence on imports, and facilitates the integration of intermittent renewable energies such as solar and wind.

What is biomethane?

Biomethane is a renewable gas obtained by fermenting organic waste from households, agriculture, or industry. With a carbon footprint 8 times lower than natural gas, it offers a sustainable and ecological alternative to meet energy needs.

How is biomethane produced?

Biomethane production involves three key steps: raw material recovery, methanization, and biogas purification. Once purified, biomethane is reinjected into the gas networks.

What are the benefits of biomethane?

Reduction of greenhouse gases: Biomethane reduces CO₂ emissions by 81% compared to natural gas.
Waste valorization: Biomethane transforms organic waste into energy and provides a natural fertilizer (digestate) to improve soil quality.
Reduction of chemical fertilizers: Digestate, rich in nitrogen, reduces the use of chemical fertilizers and promotes a healthier return of nutrients to the soil.
Storable energy: Biomethane can be transported and stored in existing gas infrastructure without additional investments.
Promotes the circular economy: Valorization of waste and reduction of environmental impacts.
