For district heating from RES and sewage sludge

Renewable energy storage technologies and their possible applications in the district heating system of Kozani were discussed by the partners of the NEUTRON project at their second meeting in Jülich, Germany, which was also attended by a delegation of EYATH, led by its president, Professor Agi Papadopoulos .

At the meeting on May 8 and 9, 2024, in which the Director of Sewerage Installations Kostas Kotoulas and the electrical engineer Vana Katsanou took part on behalf of EYATH, experts presented the latest technological developments in matters of storage and replacement by RES of the thermal energy of district heating, with possibility of application in the corresponding system of Kozani, but also in large installations. The participants also visited the MultiTESS thermal energy storage unit developed by the project partner Solar Institut Jülich of the Aachen University of Applied Sciences. Emphasis was given on the contribution of such technologies to the reduction of heating emissions of buildings, aiming at the long-term goal of Climate Neutrality by 2050.

The NEUTRON project is one of the 25 pilot projects selected as part of the European Mission of “100 Climate Neutral and Smart Cities”. It concerns the utilization of electricity from RES, such as photovoltaic and wind systems, but also the utilization of sewage sludge and biogas produced by the biological cleaning, all in the direction of the circular economy. Long-term benefits also include boosting local productivity and reducing dependence on fossil fuels.

Partners in the project, with a budget of 1 million euros, are organizations, academic and research centers, among which DEYA Kozani, Diadyma, EKETA, Aristotle University of Thessaloniki (Department of Mechanical Engineering and Law School), EYATH, Solar Institut Jülich of the Aachen University of Applied Sciences, as well as technology development companies. The opening meeting of the project took place in July 2023, in Kozani.
