Step 15:
Double-click on your ICE-process and open its card “Data”. Below, in the Output
list you can see that the credit process (in column “replaced process”) is “heatcredit-gas-heating-DE-2000”.
Step 16:
Close the inner window and open card “Filter”. Take “heat” as “Search word” and
“crediting” as “Technology Group”.
Now you can see your crediting process “heat-credit-gas-heating-DE-2000” in the list to
the left.
Step 17:
Mark it and calculate its emissions using card “Results”
The value for CO2-equivalents is 293.5 kg / MWh. As 2 MWh are credited the following
formula for allocation by crediting results: (798 – 2*293.5) kg = 211 kg. This is the value
in the table above. The formula for SO2-equivalents is: (770.5 – 2*158.22) g =
approximately 453 g.
4.3 allocation by energy
Both ICE-outputs are forms of energy: electricity and heat. On process level it is
determined that per MWh electricity 2 MWh of heat are created. If only the main output
(electricity) is considered a value of one third of the value for “no allocation” results.
4.4 allocation by energy equivalent
The energy equivalent for electricity amounts by definition to 2.5; for heat the deposited
value is only 1. So – for the allocation by energy equivalent and the production of one
MWh electricity and two MWh heat - a factor of 2.5*1 / (2.5*1+1*2) = 2.5/4.5 = 5/9
results, with whom the value under „no allocation“ has to be multiplied.
4.5 allocation by economic value
The economic value of the electricity above was 152.25 €/MWh The heat of your gas-ICE
had the economic value of 21 €/MWh. So the factor for the calculation of allocation by
economic value from no allocation is: 152.25 / (152.25 + 2*21) = 0,784
Final remark:
Via card „allocation“ in menu Extras/Settings the allocation method is globally
changeable.
The change happens to all processes if
1. they have the hook „Allow global overwriting “ (on their card Meta data) set and
2. if the method of allocation is applicable to them.
