This master thesis is part of the ComSos European project that aims to demonstrate the market potential of mid-sized fuel cells. In this work, only Solid Oxide Fuel Cells (SOFC) will be considered. A SOFC is an open electrochemical device able to produce electrical energy, and thermal energy as a byproduct, working at high temperatures and commonly using methane or hydrogen as fuels. The analysis of the energy consumption in the hotel industry will be performed in order to understand if the medium-high standard hotels represent a possible market for SOFCs development. A typical upmarket hotel needs a very high amount of energy but at the same time, it possesses a remarkable potential to reduce its consumption.
