Abstract [en]

This master thesis examined two different fuels from a lifecycle perspective and from asystemic perspective. The work focused on the combined heat and power plant, CHP8, atFortum Värme’s plant at Värtahamnen. The fuels examined were tops and branches (grot)and recycled wood chips (RWC) where the field is studied including regard to changes insoil carbon. The results showed that recycled wood produced the lowest greenhouse gasemissions. RWC were estimated to release 0.7-1.7 g CO2-ekv per MJ fuel, comparedto10.3-17.5 g CO2-ekv per MJ fuel for grot. This applied when the biogenic emission wasexcluded for RWC. The result showed that grot from the Baltic countries had lower greenhousegas emissions, 10.3 g CO2-ekv per MJ fuel, than domestic grot from central Sweden,17.5 g CO2-ekv per MJ fuel. Finally, this work showed that combustion of biofuels atKVV8 reduced emissions from the northern European electricity grid.
