CO₂ liquefaction is the process of converting gaseous CO₂, separated during biogas upgrading, into liquid form (LCO₂), a commercially valuable product used in food and beverage, horticulture, welding, and refrigeration applications. HoSt offers CO₂ liquefaction technology through its daughter company Bright Renewables, turning what would otherwise be a waste stream into an additional revenue source for biogas plant operators.
