Zusammenfassung

To address the existential threat of the climate crisis, the decarbonization of energy systems is of utmost importance. This challenge spans multiple sectors and requires strategies tailored to the specific application and available technological options. Energy system optimization through comprehensive system simulation provides an effective means for identifying the most techno-economically viable solutions. This work presents a versatile framework based on time-resolved mathematical modelling of generic energy systems that enables the determination of optimal system designs and operational strategies. The flexibility of the approach is demonstrated by several example applications: a decarbonization study of a deep-sea container ship that compares onboard carbon capture with alternative fuel solutions; a self-sufficiency-optimized industrial microgrid that examines the trade-off between cost and energy autarchy; a comparison of renewable fuel production pathways to assess future fuel price scenarios; and a macroscale analysis of the future European power system that explores the impact of localized hydrogen production on overall emissions. The framework facilitates a fast and holistic comparison of different technological concepts for energy systems and can serve as a key enabler for the implementation of effective decarbonization strategies at both the microscale and the macroscaleTo address the existential threat of the climate crisis, the decarbonization of energy systems is of utmost importance.
