LNG CI = NG to LNG + NG to CNG?

Hello,

I am calculating the carbon intensity of the LNG using version 4.03 of the GHGenius. The facility uses the natural gas from the grid to liquefaction. When running the program, should I sum the results from column Q (NG to LNG) and R (NG to CNG) to ensure that the production of the CNG from extraction to compression and transmission are included in the final CI?
If so, could you confirm if all rows from Q and R9 to Q to R20 should be summed up without the risk of double-counting? For example, the final results for the LNG CI (without exhaust combustion) of the results attached is 21,523 gCO2e/ GJ (11,531 gCO2e/GJ + 9,992gCO2e/GJ)?

Thank you for your time,
Kind regards,

Thank you for clarifying that.
I am getting very low results for the LNG CI. When I run the default values for BC version 4.03a, I get 14.58 gCO2e/MJ (11.71 gCO2e/MJ +2.87 gCO2e/MJ from exhaust emissions).
When comparing this to approved carbon intensities and secondary sources, I would expect a default CI to be ranging around 65 to 75 gCO2e/MJ. Also, the combustion of LNG looks to be higher than 2.87 gCO2e/MJ, most likely something about 50 gCO2e/MJ. Moreover, looking at the exhaust emissions tab, the cell AF142 looks more likely (50 gCO2e/MJ) than the Net CO2+non CO2 2.87 gCO2e/MJ in AF143.
Could you help me understand if I am missing something? And why the fuel use is so low?

Thanks for your time,
kind regards

Thank you, that clarifies.
I have one more question. Could you clarify what does the refuelling site in version 4.03 refers to? In this version, I have the option to enter the number of transfers for "small scale, refuelling site" and "large scale central site". My understanding is that:
- Central site is the LNG facility. # of transfers = 2 (storage tank to the truck and truck to the dispensing station)
- Refuelling station is the dispensing station. # of transfers = 1 (end-use)

Is this correct?

Thanks,
best regards,
have a nice weekend,

Thank you!
