Abstract:
A combined-cogenerative system is here presented and analysed in order to prove the concept and viability of coupling two of the most promising technologies nowadays available on the market of renewable energies and energy storage. A model based on reversible SOFC/SOE system developed within the framework of the EU funded EDEN project (h2eden.eu website, 2015) is coupled with an ORC system to exploit the waste heat coming from the hydrogen conversion process. ORC systems are renowned as one the most promising approaches to recover waste heat owing to its efficiency and reliability. ORC are able to recover a considerable part of the waste heat energy coming from both the power-to-hydrogen and water-to-hydrogen processes. Indeed, the fuel cell analyzed is able to operate as SOE system producing hydrogen when electric power is available from the grid. The design optimization of the comprehensive layout, however, is nontrivial because there exist many design variables and practical considerations. The model, based on data available from previous experimental test campaigns, is used first to complete the design of the layout and to properly size the system’s components. A simplified approach to implement and study the Steady State (SS) behaviour of the whole system is then proposed.
