INTERENERGY project final conference

The final conference of the project “Investigating energy transition pathways – interrelation between power-to-X, demand response and market coupling”– INTERENERGY , funded by the Croatian Science Foundation under the project number IP-2019-04 9482, took place, as a side event of the SDEWES 2023 Conference, at 13:30, on Tuesday, September 26th 2023 in the ROOM A. The special event chair and project leader was prof. Neven Duić from the University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture.

On this event, participants had the opportunity to get detailed information about the new, open source long-term energy planning model, which is developed with particular emphasis on the technologies that can enable energy transition towards 100% RES-based energy systems.

Also, a round table featuring the most prominent researchers in the field of energy planning took place, with the hot topic of advances in energy system modelling, including the modelling of various e-fuels, energy conversions needed for balancing of the smart 100% RES-based systems and their management.

Model presented at the conference in Greece

Researcher and member of the INTERENERGY team, Felipe Feijoo presented the H2RES model on July 12th, 2021. Presented version of the model includes power-to-x technology and demand-response modules. The model was presented at the EURO 2021 conference in Greece. The conference was held in Athens, and deals with operational research and management focusing on system optimization.

Hydrogen as a power-to-X vector in energy transition

A high-level panel was held online on 4th of March 2021, with project leader, prof. Neven Duić giving a presentation on the role of hydrogen in the energy transition. The event includes numerous presentations from distinguished researchers, such as prof. Frano Barbir (UNIST), Asst. prof. Ankica Kovač (UNIZAG FSB) and Prof. Robert Steinberger-Wilckens from the University of Birgminham, as well as a number of representatives of hydrogen and fuel cell development community.

Analysis of the Power-to-X in Denmark is online!

INTERENERGY collaborator Prof. Iva Ridjan Skov published an analysis of Power-to-X sector in Denmark, with the results indicating that the external factors such as current policy framework are more important than the internal technology related factors. Also, positive factors predominate negative ones.

About INTERENERGY project

Energy systems in the transition from fossil-based and centralized production, with high GHG emissions, to low-carbon systems based on variable and distributed renewable energy, pass through different phases of transformation. In the first phases, raise of integration of variable renewable energy sources (RES) can be performed in most of energy system configurations without the implementation of additional storage and conversion technologies. In later stages, with a high share of variable RES in the mix, synergies with other systems are needed to integrate the cheapest and sustainable energy. This project deals with interrelation between different power-to-x and demand response technologies and market coupling in the energy transition. Role of these technologies is investigated from the context of market coupling, which is already underway in the European Union. In this research, the key question which is addressed is the balanced integration of different power-to-X and demand response technologies, determining their optimal mix and avoiding unnecessary technological lock-ins. In order to achieve this, new modules will be created to model the behaviour of power-to-X and demand response technologies. Also, emerging markets for such technologies will be elaborated as well as business models for their integration. This is an important step in the digitalization of the energy system and employing the synergies in order to decarbonize multiple systems.
