37B  Production and transport emissions from methane sent to biogas upgrading system

            Note: If a project treatment facility does not send methane to biogas upgrading systems during a reporting period, EUpgrade, t will be zero.

       For the purposes of section 32, the production and transport emissions from methane sent to biogas upgrading systems for project treatment facility t during the reporting period, EUpgrade, t (in tonnes CO2-e), is worked out using the formula (equation 16A):

       where:

       t is a project treatment facility.

       EUpgrade, t means the production and transport emissions from methane sent to biogas upgrading systems for project treatment facility t during the reporting period, in tonnes CO2-e.

       h means a biogas upgrading system of a project biomethane facility.

       MSent t, h means the methane from project treatment facility t sent to 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 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 biogas upgrading system h, expressed as a fraction, which is:
          (a) 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
          (b) 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.

       γ means the factor, set out in Part 5.3 of the NGER (Measurement) Determination, that converts cubic metres of methane to tonnes CO2-e at standard conditions.

            Note: In 2022, γ was 6.784 x 10-4 x 28.
