How to Input Hydrogen and wood residue into the system and get RNG and biochar

Hi,

I've been given the task of putting wood residue and H2 into the system and receive, RNG and biochar out 

"Product: 1055 GJ/day RNG, 315 kg/hr biochar

Input: 1500 kg/hr wood, 200 kg/hr H2, 1 MW electrical energy, 2 litre diesel/hr

No emissions or other chemicals, sequester the biochar."

I've been able to input the wood, electrical energy and diesel into the system, however whenever I try to input the H2 (kg/GJ) in "Alt fuel prod" (CB 44) I end up having a very large Co2/GJ of fuel in the "Upstream Results HHV". And to my understanding I need that value to be low as it shows the emissions. 

Another problem I have is I also try and add the biochar (kg/GJ) to AX 26 in "sequestration", but that does not seem to give me any luck as it always spits out 0 g sequestered/GJ produced. 

I assume I need that number to increase as that will lower emissions. 

Just wondering how I can solve these problems

Thanks,

 

Hi Don,

Thank you for that information.

I have another question for you. How do you calculate the carbon intensity of H2 fuel with different feedstocks.

Thanks,
