Subpart P requires a facility to report annual CO2 emissions from each hydrogen production process unit. To calculate the annual CO2 emissions from each hydrogen production process unit, users must use one or more of three equations based on the unit feedstock consumed during the data collection year. Users may use different calculation worksheets for different process units as required by the feedstock type for each unit. Users may use more than one calculation worksheet for a process unit if the unit has more than one type of feedstock.
...
For each process unit with a solid feedstock, users should calculate annual CO2 emissions using Equation P-3 via the Equation P-3 Calculation Worksheet. Equation P-3 is provided below:

Use the P-1 Calculation Worksheet to calculate the annual CO2 emissions from each hydrogen production process unit with a gaseous feedstock. A separate worksheet is to be used for each fuel and feedstock used in each hydrogen production process unit. Calculations for hydrogen production process units with liquid or solid feedstocks should be performed using different calculation worksheets and different equations. The P-1 Calculation Worksheet performs the calculation using Equation P-1, provided below.

Begin by entering the facility name, your name, the process unit name or identifier, the reporting period, and any additional comments in the green input cells of the general information table located immediately below the equation in the calculation spreadsheet. This is for your records.
...
The calculation worksheet will calculate the annual CO2 emissions from a unit with a gaseous feedstock. This calculated value will be displayed in the red-bordered cell in the Annual CO2 Emissions (metric tons) from Equation P-1 table at the bottom of the worksheet. This value should be entered in e-GGRT for this process unit.
