400 participants from over 35 countries participated in the conference, which AEE INTEC organized in cooperation with UNIDO and RHC-ETIP.

The conference offered a high-caliber audience from research, industry, commerce, the energy sector, public administration, and politics the opportunity to take an in-depth look at the pressing issue of energy sovereignty, which is being driven by climate change and political guidelines.
With a focus on global solutions, the conference delved into transformative topics such as the transition to sustainable circular economies, the phase-out of fossil fuels, the coupling of energy sectors, energy storage systems, and the smart electrification of energy supply.

In six Key-note speeches, 77 presentations, 105 poster contributions, and intensive discussions, the experts explored how research findings can be translated into concrete measures for the energy transition.

Thanks to the perfect support of our support partners: The Federal Ministry Republic of Austria for Climate Action, Environment, Energy, Mobility, Innovation and Technology, KlimaAktiv, The Climate- and Energy Fund, Land Steiermark and the City of Graz. Our special thanks also go to our cooperation partners IEA TCP on Solar Heating and Cooling, IEA Energy Storage TCP, Solar Heat Europe (ESTIF), Global Network of Regional Sustainable Energy Centers (GN-SEC), Alliance ALLICE, and REN21.
