Multiple feedstock for H2 production was created by mshreya
Hi Connor,
Will there be any pathway for H2 from Renewable Natural Gas in future?Or an option to add more than one feedstock in a single pathway? It would be nice if we had the option to build a custom pathway if needed.

It is possible to do this in the existing model. If you look at rows 84 to 93 on the Alt Fuel Prod tab you will find the capacity to add other fuels to a pathway. The last three rows are placeholders where other fuels could be added.
There are two sources of RNG that take the information for that pathway in the model and use it in the fuel pathway that is of interest.
This was built to include additional fuels and not necessarily feedstocks, but for something like hydrogen the fuel is the feedstock.

Thank you, Don.
A followup question on this.
The Sheet Fuel Char has a section : " MIX OF FEEDSTOCK FOR FUELS".Cell B28 has a default value for "Hydrogen from natural gas (rest from water electrolysis).". When we use RNG as a feedstock along with NG, do we need to specify what fraction of total feedstock is from NG? If so, where do we do that?
Also, in the same sheet, for the section FUEL CHARACTERISTICS: INPUT/ACTIVE DATA , I could not find anything for RNG. Could you kindly help to locate the fuel characteristics of RNG, so that it could be changed if needed.
Thanks,
mshreya

You do not need to change the values in B28 to run RNG.
We assume that the methane and N2O emissions are the same for RNG and NG. We don't track the carbon balance for renewables fuels as we do for fossil fuels.
