H2 generation through NG-carbon capturing was created by parthos
Hi,
If the hydrogen is generated form Natural Gas through reforming and CO2 is been captured as shown in the figure below, how could I manipulate data for that hydrogen LCA. Additionally, if electrolysis is powered by renewable as shown in figure, how could I generate LCA for this process.

For the electrolysis pathway you can define the source of power.
1. On the Power Gen sheet select the mix of power in row 21.
2. On the Upstream Emissions sheet in cell CP11, change the term Elec Emissions'!$B55 to Elec Emissions'!$B56.
Your hydrogen production emissions will be in Column CP.
Note that all sources of electricity in the model have some emissions, there is no such thing as zero emissions electricity.

For the SMR pathway you make the following changes.
1. On the Input sheet in cell B69 enter 1.
2. Go to the sequestration sheet, enter your sequestration parameters in column P, rows 19 to 26.

The results are found on the Upstream Emissions sheet in column CR.
