Energy System Modelling and Optimisation

The development of novel energy technologies calls for accurate models capable of predicting their performance and operational issues, as well as effective optimisation tools to determine the most advantageous design and operating solutions. Since the early 90’s, the GECOS group has developed and validated detailed models of advanced energy systems (cooled expanders, fuel cells, membranes, etc) in collaboration with leading energy companies and research institutes. These models are integrated with state-of-the-art numerical methods with the final aim of determining the optimal process design, heat integration/recovery, planning/scheduling and operation.
