In the Sustainable Energy Systems research group, we are working on integration and optimization of efficient, flexible and sustainable energy systems. Our research includes development of concepts for energy storage and processes for conversion of renewable energy to fuels (Power-to-X and Bio-to-X). The PhD Candidate will work on systems level modelling, design and optimization for such processes. The research will focus on developing methods for integration, flexibility and sustainability, in order to handle variable and uncertain operating conditions. Process insight should be utilized to develop methods for design and optimization of integrated systems. The research may include both use of commercial simulation tools and in-house model development for unit operations, as well as hybrid models. The project is open for different applications. Hence, the applicant should submit a project outline including suggestions for applications and integration opportunities, and suggestions for required development in methodology.
