Emission and economic performance assessment of a solid oxide fuel cell micro-combined heat and power system in a domestic building

摘要: Combined heat and power (CHP) is a promising technological configuration for reducing energy consumption increasing security in the domestic built environment. Fuel cells, on account of their: high electrical efficiency, low emissions useful output have been identified as key option improving both building efficiency CHP applications. The work presented this paper builds upon results currently reported literature fuel cells operating applications, with an emission economic performance assessment real, commercially available SOFC mCHP system real building; under UK context. This aims to assess solid oxide cell (SOFC) system, at University Nottingham's Creative Energy Homes. evaluates, over one year period, associated carbon (emission assessment) operational costs (economic case compared ‘base case’ grid electricity highly efficient gas boiler.
