Abstract [en]

This contribution is based on the result of a project entitled "Systems Analysis: Energy Recovery from waste, catalytic combustion in comparison with fuel cells and incineration" is financed by The Swedish National Energy Administration. The aim of the project was to assess the energy turnover as well as the potential environmental impacts of biomass/waste-to-energy technologies. Four technology scenarios are be studied: (1) Gasification followed by low temperature fuel cells (i.e. Proton Exchange Membrane (PEM) fuel cells) (2) Gasification followed by high temperature fuel cells (i.e. Solid Oxide fuel cells (SOFC)) (3) Gasification followed by catalytic combustion (CC) and (4) Incineration with energy recovery. Looking at the result of the four technology chains in terms of the impact categories considered with impact per GWh electricity produced as a unit of comparison and from the perspective of the rank each scenario has in all the four impact categories, SOFC appears to be the winner technology followed by PEM and CC as second and third best respectively with incinerations as the least of all. On other hand, looking at the three important emissions (CO,. NOx and SOx) from the total systems (include both the core system and the external system), SOFC is the best technology equally followed PEM and CC as the second best. A comparison of the same emissions from the core systems places CC on equal level with SOFC as the best technologies with PEM as the second best.
