Forgotten or irreplaceable? The role of district heating in the energy transition

The seminar is aimed at district heating operators, researchers, and developers.

The event can accommodate 50 participants.

The seminar program is free of charge for participants. We offer participants a bus ride to the excursion sites on Wednesday's excursion day.

Participants book and pay for their own accommodation and travel.

Seminar participants can get a 10 % discount on daily room rates at Hotel Verso.

Room reservations can be made directly from Hotel Verso home page with the booking code JAMK. Alternatively, reservations can be made by phone to Hotel Verso reception +358 14 333 999 or by email info@hotelliverso.fi.

The presentation covers the conditions under which low-temperature, variable waste heat can be techno-economically integrated into district heating, and the role of fourth-generation district heating in this and in the energy transition more broadly.

Speaker: Altti Meriläinen, M.Sc. (Tech.), works as a Junior Researcher in the Department of Electrical Engineering at LUT University. He researches how renewable electricity and thermal energy generation and storage as well as energy flow control are techno-economically co-optimized for buildings and industry as part of the surrounding energy system. In his dissertation, he explores the conditions under which low-temperature waste heat generated in water electrolysis can be utilized cost-effectively in district heating and direct air capture of carbon. Additionally, he researches the electrification of heavy road transport, with a particular focus on design and control of charging infrastructure. In his free time, he enjoys various activities, including cycling, running, skiing, and working on personal engineering projects.

Speaker: Riku Martikainen, Business Manager at ALVA.

This work shows how demand-side optimisation can unlock low-temperature waste heat integration in district heating systems without requiring deep building retrofits. Using high-resolution monitoring and data-driven analysis in Viborg, the study identifies operational bottlenecks and demonstrates achievable reductions in supply and return temperatures. The results highlight how building-level control and data integration can translate into system-level gains, improving efficiency and enabling future large-scale waste heat utilisation.

Speaker: Michele Tunzi, Associate Professor in the Civil and Mechanical Engineering Department at Technical University of Denmark
