Thermodynamic analysis of a shared cogeneration system and electrical mobility located in a Northern Europe climate

Transition to alternative energy systems is required in EU countries. The aims are to decrease greenhouses gases emissions, relevance of fossil fuels for energy production and energy dependence on extra-UE countries. These goals could be achieved varying energy sources, for example increasing renewable energies and/or efficiency on energy production. This process of transition would require many years meanwhile it is necessary to use energy sources with a lower environmental impact. In this paper an innovative energy systems for household application is presented: it covers heating request and supplies electricity for user. SOFC (Solid Oxide Fuel Cells), heat pump and Stirling engine are utilised all together to achieve the maximum efficiency. In this case it is also simulated a transition from traditional petrol cars to electricity mobility. Different types of fuels are considered in this study to demonstrate the high versatility of SOFC as cogeneration system just changing the pre-reformer system. Thermodynamic analysis is performed to prove high efficiency even if different fuels are used.
