As stated in the other replies, upgrading costs depend on key parameters, such as the gas flow, the concentration of contaminants to clean your biogas (H2S, VOCs, Siloxanes) and the technology you choose (ie. membrane upgrading, amines, PSA). The size of the project would naturally also impact CapEx and OpEx. Depending on the project, gas cleanup and upgrading could cost anything from $1M – $15M, so the answer here is ‘it depends on your project’.
