Small Scale Biogas Upgrading Plant

Page last modified
August 4 2023

A small scale LP-Cooab (Low-Pressure CO2 Absorption) upgrading system was standardized in collaboration with CCS, branded Bio-Up®, specifically to make biogas upgrading available for normal sized farms. A dairy farmer with 200 cows (or equivalent) is already able to profit from sustainable energy production, depending on your national renewable energy benefits. Bio-Up® is completely integrated in a standard 40ft container and delivered pre-assembled on site. A fully automated system and remote control means that it is easy to operate.
