Increase biogas revenues with accurate methane volume calculation

Making biogas production profitable as quickly as possible is typically one of the most important factors when starting up or developing a biogas plant. Subsidy payments often require Combined Heat and Power (CHP) efficiency above a certain value. The calculated methane production (expressed in cubic meters per hour) represents the energy input to the CHP engine, which is the starting point for the efficiency calculation. Overestimating the energy input makes it more difficult to achieve the efficiency required for claiming the subsidy, which can have significant consequences for the plant.

In order to achieve the required efficiency level it is critical that your methane measurements are not wrong due to incorrect compensation. Biogas plants typically calculate methane volume by multiplying dry methane concentration (extractive measurement) with wet flow rate (in-situ measurement), which results in an error in the calculated volume that is proportional to the humidity of the gas.
