Abstract

Integrated and combined cycles traditionally involve gas and steam turbines only. The paper analyses the integration of high-temperature fuel cells (FC) into Fuel Cell Combined Cycles (FCCC) and their use for the synthesis of complete CHP (Combined Heat and Power) networks. A synthesis procedure is presented utilising biomass and fossil fuels. This involves significant combinatorial complexity efficiently handled by the P-graph framework and its associated algorithms. This contribution provides a tool based on a procedure for efficient evaluation of early-stage energy technologies, specifying a set of market conditions and then testing the resilience of the design against variations of key parameters. The results show that such systems employing renewable fuels can be economically viable for a wide range of economic conditions, mainly due to the high energy efficiency of the FC-based systems. Further research and development with industrial relevance are outlined focusing on CO2 emissions reduction.
