45  Methane destroyed in biomethane produced by project biomethane facilities

  The volume of methane sent out from project biomethane facility f during a reporting period (BCf), in cubic metres, is worked out using the following formula:

 

| A formula to calculate the methane destroyed in biomethane produced by a biomethane facility f during a reporting period. | Equation 16 |

 

 

| K | means a biogas upgrading system that is part of project biomethane facility f. | | Q subscript BM comma k | means the total volume of biomethane sent out by biogas upgrading system k during the reporting period, in cubic metres, determined in accordance with the monitoring requirements. | | W subscript BM comma CH4 comma k | means the proportion of QBM, k that is methane, expressed as a fraction, determined in accordance with the monitoring requirements. | | TL subscript BM comma f | means the transport loss factor for biomethane produced by project biomethane facility f, expressed as a fraction, which is: <br>    if all biomethane produced by the biogas upgrading system f during the reporting period is consumed at the project landfill or a project biomethane facility—zero; or     otherwise—0.02.<br>Note:  TLBM accounts for methane that is not combusted due to gas lost in transport of biomethane. | | DE subscript BM | means the methane destruction efficiency for biomethane produced by a biogas upgrading system, expressed as a fraction, which is 0.98. |
