We have developed next-generation of water- and amine-based biogas upgraders that enable biogas plants to be operated more efficiently and with the option of converting the biogas stream not only into natural gas grid specification methane but also into high-value products such as liquid bio methane and bio CO2
Airco Process Technology – Obviously Green
When biogas from AD’s is split into Methane and Carbon Dioxide in a Biogas Upgrading plant, normally only the Methane is utilized. It is however relatively easy also to capture and utilize the Bio CO2, offering a second value stream
Why Upgrade Biogas
In most cases upgrading biogas to biomethane for the natural gas grid is the most financially attractive option for biogas plant owners.
In addition to the methane stream, there is a significant CO2 stream from biogas upgraders. Traditionally this has been viewed as a potential liability, but with the current investments in Power-to-X technologies, there will be a very substantial need for CO2 from green sources, such as biogas.
Biomethane from our upgraders can also be liquefied (as CBG or LBG) and can for instance be used in the transportation sector (trucks, heavy machinery, ships).
