District Heating De-Carbonisation in Belgrade. Roadmap.

The operation temperatures of today’s district heating systems are too high for a massive integration of renewable systems, while the current control systems are no able to properly introduce weather-dependent, distributed heat sources such as solar systems. The district heating strategy for the city of Belgrade (Serbia) addresses these barriers with the focus to de-carbonising the city on a multi-year transition plan, including large investments, greater interconnection levels with large solar thermal plants and waste incineration plants, and the conversion of a power plant into CHP, among others. The size of the Belgrade district heating network, one of the biggest of Europe with >12PJ heat sales only compared to few district heating networks such as Copenhagen’s (>30PJ heat sales) or [...]

Demonstration site: the conversion of the district heating network of Iurreta into an ultra-low temperature system

The main aim of Iurreta demonstration site is to tests the possibilities of the ultra-low temperature district heating systems in corporate building complexes. For such purpose, the intervention proposed within the framework of RELaTED project requires the conversion of current district heating network into an ultra-low temperature system, where the operation temperatures are reduced, and additional distributed renewable heat sources are introduced. Current technical barriers to achieve this conversion will be solved by means of installing innovative technologies as building integrated solar thermal systems and reversible heat pumps capable of operating at ultra-low temperatures. This new ultra-low temperature network will allow to increase the efficiency of the existing heat plant by reducing water production temperature in one of the boilers. [...]

6th RELaTED General Assembly: the project partners presented their advances in Ultra-Low Temperature District Heating

The COVID-19 pandemic forced the RELaTED partners to gather virtually for their 6th General Assembly. The agenda for these days included an intense series of partners discussion, online workshops and technical coordination. This time, the RELaTED team worked by virtual meeting due to COVID-19 pandemic. Despite the circumstances, partners connected by video meeting from home and keep the project on track, focusing on the execution and technical coordination of the next months of work. During this four-day virtual meeting, the partners presented to the consortium their progress in the different work packages. They also explained their advances in the RELaTED Ultra-Low Temperature district heating solution and established a work plan for the following semester. After these intense series of online [...]

RELaTED project will be at the CoolDH & Celsius Talk on Low Temperature District Heating

RELaTED Project will be at the CoolDH & Celsius Talk: Low Temperature District Heating by the hand of Christian Holm Christiansen, Senior Consultant at the Danish Technological Institute (DTI). Place: https://zoom.us/j/893355855 Date: Thursday, April 16, 2020. Time: 10:30 - 11:30 CET. Organizer: Celsius Initiative & COOL DH. Register for the webinar >> Decarbonised district heating systems are already here and some of them are spelled low temperature district heating (LTDH). As a matter of fact, low temperature district heating can prove to be an important part in keeping the globe’s temperature low as well. This webinar will present some of the opportunities and challenges cities may encounter in their endeavour towards a sustainable and efficient energy system. This webinar is hosted [...]

Low temperature district heating project in Tartu, Estonia

Fortum Tartu is investigating new possibilities and solutions for developing the low temperature concept developed by RELaTED project in Tarkon, a selected part of the existing district heating network. The main idea is to investigate whether it is possible to lower the district heating supply temperatures in the existing district heating system, what its benefits are and where the limits are. The using of waste heat from industry as an energy source for district heating is also a part of the proyect. Read more about the technical concept of Tartu's demo site in the following document.

District heating: the key to decarbonising Europe’s heating

District heating (DH) systems are one of the most energy efficient heating systems in urban environments, with proven reliability within many decades already. District heating systems are identified as key systems to achieve the de-carbonization of heating energy in European Cities. Renewable and waste heat sources are foreseen at the same time as decarbonized heat sources and the way to guarantee competitive energy costs with limited influence of fossil fuel supply price volatility. To achieve this, a transition is needed in DHs, comprising not only measures to improve overall performance (temperature level reductions, improvement of substations, etc.), but to guarantee system viability as a whole in a context of reduced heat loads with the transition to Near Zero Energy Buildings [...]

Solar thermal potential in the district heating system of Belgrade City

The use of renewable energy sources as biomass, solar thermal solutions, geothermal energy, and waste heat is becoming more popular in Europe. The transition of district heating systems from fossil fuels to renewables is the next step in the development of district heating, but there is still a lot of work ahead for everyone, not only in the local level but in the whole world. Chairs of Opening ceremony: prof. dr Branislav Todorović, prof. dr Bratislav Blagojević and dr Milovan Živković (Photo: Serbian Society for HVAC&R). These are some of the topics discussed at the regional conference Renewable Energy Sources in District Heating and Cooling Systems held in Belgrade last december. This event was organized by the European [...]
