Upgrading the performance of Tuzla’s District Heating Networks

The city of Tuzla is placed in North-East part of the country, with around 170,000 inhabitants. The DH system is based on cogeneration (CHP) in Tuzla’s coal-based power plant (Tuzla TPP)operated by EPBiH power utility. Tuzla TPP is the supplier of heat to both Tuzla City (220 MWth) and Lukavac city (50 MWth). In the near future, the town of Živinice is planned to be supplied with a thermal power of 70 MWth.

District Heating Network Kortrijk

The City of Kortrijk installed a pilot heatnet at Kortrijk Weide, as a nucleus for further extensions in the city. The feasibility to install a heatnet backbone from the waste incinerator at the outskirts of the city, along the River Leie, to the city center was researched. As many building projects are taking place along the river, this would create the opportunity to connect over 1,000 households.

Biomass Heating Grid in Grassau

In the Achental Valley, a mountainous area located in the south of Germany, a heating grid has been installed driven by wood chip burning. The potential of using biomass in the region has been discovered during the European RES-Integration project. This project has studied renewable energy potential in various poor regions across Europe. It resulted in the installation of a biomass center in Achental in combination with a boiler house, connected to a heating grid for 500 consumers.

Zero-emission Settlement in Bad Aibling

In the south of Germany a small district heating network has been installed in the town of Mietraching/Bad Aibling. The main sources of district heating are a woodchip boiler, mainly used in cold days, and solar collectors, mainly used in the warm days. The solar collectors are connected to centralised and decentralised buffer tanks for energy storage. Furthermore, a gas installation is delivering peak load for in mid-winter. The district heating network supplies heating to about 130 households, 2 schools, office buildings and a hotel.

District heating in Bornholm and Bornholms Forsyning

In 2008, the Regional Municipality of Bornholm decided to become a 100% sustainable and CO2-neutral society in 2025, in which only sustainable and renewable energy is used. In 2019, already 60% of the island’s energy is produced fossil-free by using wind, sun and biomass power. The island’s green vision, big share of renewable energy, citizen and community involvement and replicability of the energy solution helped in winning the 2019 RESponsible Island Prize.

Establishment of a district heating network in Ghent

Arcelor Mittal Ghent has a lot of residual heat, which is currently cooled down in order to discharge it in a canal or into the air. Local authorities and the company are investigating whether the residual heat could be used for a heat network towards Zelzate and Terneuzen. The Province of East Flanders acts as an energy broker that brings stakeholders together, to create support and to support actions towards realization.
