I believe I have discovered an error in the CRNG feedstock transport calculation. On the Transport tab, cell BA50, the formula is:
=$B$50/(1-'Fuel Char'!$J$144)

The denominator in this equation is to account for the moisture content of the organics. However, cell BA50 is then carried into cell BA57, the formula is:
=BA56/'Fuel Char'!K144/1000000/(1-'Fuel Char'!J144)

It is my understanding that the moisture content is accounted for twice in this calculation and therefore the feedstock transport emissions are overestimated. This is also true for the manure transport calculation (Transport AZ50 and AZ57).

This error becomes more clear when manipulating the moisture content of the feedstock to a high value. In my case, I had manure with a moisture content of 95%.

Could you please look into this and let me know if I should manipulate the formula?

Thanks

We are aware that the moisture content if factored in twice. It will be fixed in the next update.
