The HI2 Valley project promotes the development of a large-scale hydrogen (H₂) economy based on renewable energy sources in the Austrian industrial regions of Upper Austria, Styria, and Carinthia. The project is currently looking at the regulatory framework along the hydrogen value chain (Jovana Winkler) and perceptions of hydrogen, with the aim of deriving recommendations […]

Connecting district heating networks allows their heating plants to be used jointly, making supply more sustainable and cost-effective. Until now, there have been no connections between district heating supplies in different cities. Researchers at the Energieinstitut an der JKU have investigated whether connecting heating networks could lead to cost savings and positive environmental impacts. One

The Energy Institute at JKU Linz took part in the 20th Conference on Sustainable Development of Energy, Water and Environment Systems (SDEWES) in Dubrovnik – a city well known to Game of Thrones fans. In this impressive setting, our researchers presented new insights into the future of sustainable energy systems: Just like in Westeros, the

Our colleagues, Hannah Aster & Lukas Zeilerbauer had the privilege of attending LCM 2025 – the 12th International Conference on Life Cycle Management – in Palermo from 9–12 September 2025! This year’s theme, “Global to Local”, provided an inspiring platform to explore how life cycle approaches can be translated into real, impactful actions across different

A day with climate communicator Andreas Jäger. At the JKU Somnium, we honed our skills in science communication. Our work at the Energy Institute delivers a wealth of results! These are of great importance for economic and social development. This makes it all the more important to be able to package this scientific excellence in

In the HEATROCK research project led by Melanie Hörtler (Hoertler) from LINZ AG and in collaboration with other Austrian project partners, we are investigating innovative solutions for seasonal heat storage in district heating systems. The project examines the technical, ecological, economic, and legal aspects of hot water storage in caverns in crystalline rock. A publication

An article by our colleagues Simon Moser, Hans Böhm, Anja Gahleitner and Valerie Pfeffer-Rodin has been published in the latest issue of the magazine ‘nachhaltige technologien’ (03|2025). The issue is dedicated to the topic of industrial-urban symbiosis – from coexistence to cooperation. The article highlights, among other things: An exciting insight from Task 21 of

Our colleague Katrin Burgstaller, together with her project colleagues Wolfgang Haider and Andreas Bernögger, has recorded a very interesting podcast about their joint ACRP research project Hashtag#UrbEnPro! In the TU Vienna’s Zukunft Stadt podcast, they talk to Lena Hohenkamp, who is also part of the project team, about social innovations in the energy sector and

This week, our team had the pleasure of participating in the 19th International Symposium on District Heating and Cooling in Genk, Belgium.Thanks to EnergyVille, VITO and IEA DHC for hosting such a well-organized and inspiring event. Katharina Rusch shared results from the HeatHighway project in her presentation on “Economic evaluation of a heat highway between

On July 8, our colleague Michael Denk visited the Energy Research Institute of the Shandong Academy of Sciences (SDAS) in Jinan, China. During his stay, he gave a presentation on “The AI Power Paradox”, in which he highlighted the potential and challenges of the application of artificial intelligence in the energy system and the associated
