Roman Hackl's project aim is to develop the Total site analysis method (TSA) for analysing opportunities for implementation of common energy efficiency measures and advanced biorefinery concepts in industrial clusters. The project is to be conducted as a case study linked to the chemical complex in Stenungsund. The project will contribute to increased experience of how the TSA method can be used for energy systems analysis in industrial clusters. The potential for energy saving measures will be quantified and integration of a few selected biorefinery processes in the Stenungsund cluster will be investigated. Example for biorefineries are bioethylene production from lignocellulosic feedstock via fermentation and algae based biorefinery concepts. The selected cases will be evaluated with respect to techno-economic performance as well as associated potentials for reduction of CO2 emissions using energy market scenarios.
