Call for Abstracts

The focus of ISEC 2026 will be on how we can achieve energy sovereignty within a time horizon dictated by climate change and defined by politics.

Central topics will include the transformation of our economic system towards a sustainable circular economy, the complete phase-out of fossil fuels, and the implementation of sector coupling, energy storage systems, and smart electrification.

Special attention will be given to the ongoing transformation of energy infrastructure and urban energy systems as a key element of the energy transition. In this context, continued research and innovation, as well as the specific challenges and opportunities in the Global South, will be essential and the focus of the conference.

The Call will be open from 1. June - 31. August 2025.

Details about the Call for Abstracts will be published by the end of May on the ISEC-Website.
