41G   Gross abatement amount for a project biomethane facility

       The gross abatement amount for project biomethane facility m for a reporting period, GAdisplacement, m (in tonnes CO2-e), is worked out using the formula (equation 23):

       where:

       h is a biogas upgrading system at project biomethane facility m used during the reporting period.

       m is a project biomethane facility.

       QBM, h is the total volume of biomethane sent out by biogas upgrading system h during the reporting period, in cubic metres, determined in accordance with the monitoring requirements.

       ECNG is the energy content factor for natural gas distributed in a pipeline, in gigajoules per cubic metre, set out in Part 2 of Schedule 1 to the NGER (Measurement) Determination.

       EFNG, CO2 is the carbon dioxide (CO2) combustion emissions factor for natural gas distributed in a pipeline, in kilograms CO2-e per gigajoule, set out in Part 2 of Schedule 1 to the NGER (Measurement) Determination.

            Note: Methane (CH4) and nitrous oxide (N2O) emissions are constant regardless of whether biomethane or natural gas is combusted, and hence do not result in displacement abatement.
