Dear all,
My problem is about emission credit for cleaner electricity:
I use a fuel cell (FC) for supplying a single family home (SFH) with heat (e.g. 17,000 MJ/a) and electricity (e.g. 14,000 MJ/a).
However, since the electricity demand of the SFH is only 13,000 MJ/a the FC actually, produce more electricity than needed. Hence, the SFH exports electricity to the grid.
I like to compare the “Life Cycle Impacts” per year of supply of heat and electricity by a FC compared to the supply by a system consisting of a “conventional gas condensing boiler” plus “electricity from the grid” (e.g. using the ENTSO-E electricity mix).
I would like to account for the fact that emission per kWh electricity surplus produced by the FC are lower than the emission per kWh using the ENTSO-E electricity mix.
Hence, I would like to give an emission credit to the “Life Cycle Impacts” per year of the FC. This corresponds to "the emission per kWh electricity using the ENTSO-E electricity mix" times "the electricity exported by the SFH".
Is there an elegant way to include this in an Umberto model?
Thank you and best regards,
Phil
