Sequestration Inputs for RNG Upgrader Emissions

Hello,

I am working on a Manure-to-RNG anaerobic digester project where the exhaust stream from the biogas upgrader gets captured and sequestered. The natural gas combustion emissions do not get captured.

I am currently unsure whether cell AZ19 in the Sequestration tab should be the fraction of captured upgrading emissions over the total released CO2 from the upgrader or the fraction of captured upgrading emissions over the total released CO2 from the entire process. Could you please clarify?

Additionally, the emissions from the upgrader are biogenic CO2. Does the model consider this and distinguish this from non-biogenic CO2 in the results?

Thank you

Hi Don,

Thank you for your response. I understand cell AZ19 can be adjusted to reflect the value in AZ30, but cell AZ30 is not used in the Upstream Results HHV and BC LCFS results. Could you please clarify?

Thank you,
Fiona
