COMETS is to develop a decision tool for identifying and optimizing policies and investments within an integrated energy system framework incorporating the transportation sector, supporting Denmark’s 2050 goal of becoming independent of fossil fuels.
With the transport sector being powered by an increasing share of renewable fuels, it will become increasingly integrated into the energy system: biofuels, hydrogen, electricity, and other alternative fuels have production chains with strong linkages to the broader energy system.
Some of the fuels can function as energy storage adding flexibility in the production of electricity and heat, and excess heat from the production of the fuels can be used for district heating or industrial processes Current energy system models cannot fully handle interactions between the energy and the transport systems, limiting their ability to model changes that affect both systems, e.g., modal shifts in transportation, transportation time optimization, and the influence of transport infrastructure investments on the energy system.
This project will develop soft-links between a newly developed behavior-based transport model and an integrated energy system model for Denmark. The combined modeling system will then be used to analyze different policy scenarios for energy and transportation with a participatory approach involving relevant stakeholders.
