37  Emissions from combustion of biogas

       For the purposes of section 32, the methane combustion emissions from methane destroyed by combustion devices or taken to have been destroyed by biogas upgrading systems for project treatment facility t during a reporting period, ECom,t (in tonnes CO2-e), is worked out using the formula (equation 16):

       where:

       t is a project treatment facility.

       ECom,t means the methane combustion emissions from methane destroyed by combustion devices or taken to have been destroyed by biogas upgrading systems for project treatment facility t during the reporting period, in tonnes CO2-e.

       h means:
          (a) a combustion device used at project treatment facility t; or
          (b) a biogas upgrading system of a project biomethane facility.

       MSent t, h means the methane from project treatment facility t sent to combustion device or biogas upgrading system h during the reporting period, in cubic metres, worked out in accordance with section 30.

       PLh is the biomethane production loss factor for biogas sent to combustion device or biogas upgrading system h, expressed as a fraction, worked out in accordance with section 37A.

            Note: PLh accounts for methane lost during biogas upgrading. It does not affect methane that is sent to combustion devices.

       TLh is the transport loss factor for biogas sent to combustion device or biogas upgrading system h, expressed as a fraction, which is:
          (a) if h is a combustion device—zero; or
          (b) if h is a biogas upgrading system and all biomethane produced by the biogas upgrading system during the reporting period is consumed at a project treatment facility or project biomethane facility—zero; or
          (c) otherwise—0.02.

            Note: TLh accounts for methane that is not combusted due to gas lost in transport. It is only relevant when a project undertakes biomethane production and sends the gas off-site for use and combustion.

       ECBG means the energy content factor for sludge biogas that is captured for combustion (methane only), in gigajoules per cubic metre, set out in Part 2 of Schedule 1 to the NGER (Measurement) Determination.

       j means a greenhouse gas type, which is methane or nitrous oxide.

       EFj means the emissions factor for greenhouse gas type j for combustion of sludge biogas that is captured for combustion (methane only), in kilograms
       CO2-e per gigajoule, set out in Part 2 of Schedule 1 to the NGER (Measurement) Determination.
