H2 fuel cell vs incumbent gasoline and diesel vehicle intensities

Hi, just want to make sure I am using the program correctly to compare the total life cycle CO2e emissions for H2 fuel cell vehicles relative to the typical gasoline and diesel fuels on a per km basis. The H2 is assumed to be produced from natural gas via a SMR, with carbon capture. It is assumed the gasoline and diesel are produced via refinery pathways from crude oil. My understanding is as follows:

1) On the worksheet "Output Summary" I would compare "Fuel Cell CH2 NG100" to the other fuels.
2) Any suggestions on what the best gasoline/diesel would be considered for incumbent fuels used in Canada - i.e. there are so many different gasolines/diesels.

Thanks.

It would be best to take the results from the Lifecycle Results sheet.

The FCV would be in column T, rows 6 to 29 for the light duty vehicle.

The gasoline emissions would be either column C for 100% gasoline in the same rows 6 to 29 or Column B rows 33 to 56 for a 10% ethanol/90% gasoline blend.

Thanks you for the prompt response.

to confirm on the lifecycle results tab the Hydrogen CH2 (NG-100/Water0) in column "I" would refer to a vehicle with direct internal combustion of compressed hydrogen produced solely (100%) from SMR of natural gas, with 0% electrolysis hydrogen?

Yes, column I on the lifecycle results sheet is for a hydrogen powered internal combustion engine.
The choice of hydrogen production system for this pathway is found on the Input sheet in cell B49.
