We recently proposed to increase efficiency of an industrial energy system with the adoption of a RSOC (Reversible Solid Oxide Cell). The aim is to produce both heat and electricity, increase the match between energy production and consumption meanwhile hydrogen is produced.
An existing paper mill located in Italy was analysed with the aim of revamping a part of the energy generation system with the adoption of RSOC/SOFC to dismiss one of the old steam turbine.
Thermodynamic analysis shows that primary energy saving is achieve even if hydrogen is produced.

In this study an innovative micro-cogeneration system for household application is presented: it covers heating, domestic hot water and electricity demands for a residential user. Solid oxide fuel cells, heat pump and Stirling engine are utilised as a system to achieve high energy conversion efficiency. A transition from traditional petrol cars to electric mobility is also considered and simulated here. Different types of fuel are considered to demonstrate the high versatility of the simulated cogeneration system by changing the pre-reformer of the fuel cell. Thermodynamic analysis is performed to prove high efficiency with the different fuels.
