    The driving factor for the capturing and selling of CO2 in biogas plants is the demand. Until 3-4 years ago, there was no real demand for biogenic CO2. Around the COVID era and after, the CO2 production got disrupted and markets started looking elsewhere. Capturing and producing liquified CO2 from a membrane upgrading system is easy and the equipment can be installed at the same time or later on.

    The numbers might seem small at the moment but interest is growing and many new projects are considering CO2 as a revenue source. It would actually turn otherwise non economically feasible projects into successful ones.

    The demand is there, from sequestration to greenhouses, food and beverage. All we need is time, for the word to get out to existing upgrading plants and for developers / engineers to start including CO2 capture at the conception point of the project, in order to secure funding for the CapEx.
