SURE employs a comprehensive energy modelling framework, and in this regard, model development is essential to answer the project’s research questions. A milestone on the development of PSI’s Swiss TIMES Energy system Model (STEM) has been reached and published by Michel Obrist who enhanced the model for a specific industry sector. Insights on the advanced modelling approach are available in his article “Long-term energy efficiency and decarbonization trajectories for the Swiss pulp and paper industry”. https://doi.org/10.1016/j.seta.2021.101937
