Solutions for biogas and bioCO₂
For over 30 years, Air Liquide has been developing solutions for valorizing biogas from methane digesters. Through membrane purification, the biogas is separated into bio-CO₂ and biomethane. Various gas liquefaction technologies are then implemented to facilitate transport and use.
Air Liquide, a complete range for biogas and bioCO₂
Biogas purification units
Air Liquide offers tailor-made biogas purification solutions with highest efficiency of the biogas purification and separation. Our membrane technologies effectively separate methane from CO₂.
The resulting biomethane can thus be injected into the natural gas network or used as a fuel for land and sea transport, for example. With an extraction rate of over 99.5%, our solutions contribute to optimal biogas recovery.
A green gas that's good for the environment
Biomethane (or bioLNG after liquefaction) is a renewable energy source that plays a key role in decarbonising industry and heavy mobility. Derived from the digestion of organic matter (methanisation), it is considered CO₂-neutral as it does not contribute to the increase in the greenhouse effect.
