Biogas - more cost effective upgrading using biocatalyst

One major barrier for increased use of biogas in the natural gas grid is the cost of upgrading the biogas. Upgrading is basically removing Carbon Dioxide from biogas so only Methane remains in the gas. However the cost of energy required in the commercially available technologies add a substantial cost to the upgraded gas. By using an biocatalyst the efficiency of the upgrading process can be increased and the cost of energy reduced. A partnership has been formed to demonstrate the technology on a full scale basis. The project also demonstrates how the biogas upgrading can be integrated in the biogas system at a waste water treatment plant producing the biogas and injection of the upgraded gas in the natural gas grid. When the ENZUP upgrading facility commences in full operations end 2015, this is expected to be the largest demonstration of a biocatalyst-based approach to remove Carbon Dioxide from an industrial gas stream anywhere in the world.
