Activities: biomethane production
Start: January 2023
In January 2023, TotalEnergies commissioned the BioBéarn biogas production unit in Mourenx in the south-west of France. With an annual production capacity of 160 gigawatt hours (GWh), BioBéarn has reinforced our position as a major biogas player in France and Europe.
BioBéarn has been built on a 7-hectare former brownfield site in the center of the Lacq basin and represents TotalEnergies' 18th biogas production unit1 in France. The unit will be capable of converting 220,000 tons of organic waste every year from local farming activities and the agri-food industry.
The anaerobic digestion process converts this feedstock into biogas. Once purified, the biogas becomes biomethane, which is a renewable and carbon-free gas offering similar characteristics to natural gas. Its production has been certified as sustainable by ISCC2 under the highest sustainability criteria of the EU REDII Directive.
Since January 2023, the unit has been feeding its biomethane into the natural gas transmission network operated by Teréga. It will gradually be scaled up to produce up to 160 GWh at 100% capacity, which is equivalent to the average annual consumption of 32,000 inhabitants. By avoiding the emission of 32,000 tons of CO2 per year, BioBéarn is also enabling the Lacq basin, a historical gas area, to achieve local and sustainable growth.
Finally, as part of a Biomethane Purchase Agreement signed in June 2023, BioBéarn will supply Saint-Gobain France with 100 GWh of biomethane over a three-year period starting in 2024. As such, we are supporting Saint-Gobain with its efforts to reduce its greenhouse gas emissions in France.
