“The global crisis of COVID-19 has highlighted the importance of the sustainable Energy Transition”

Author: Olga Macías, Smart Buildings and Cities Researcher at TECNALIA Research and Innovation. The last few months all the news has been overshadowed by the global crisis of COVID-19. This pandemic has turned the whole world upside down and shaken worldwide economies. Among other consequences, many of us agree that this crisis has highlighted the importance of the sustainable Energy Transition, and the need to search for solutions with technical and economic feasibility that will facilitate this transition. That is why, now more than ever, we believe in the concept of ultra-low temperature, de-carbonized and smart networks developed in the RELaTED project as a solution that allows transforming the current district networks with a greater use of renewable [...]

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. [...]

WEBINAR: The low temperature district heating recording is now available

Watch and listen to the Low Temperature District Heating webinar, hosted by Celsius Initiative in partnership with COOL DH. Learn about how smart cities can transition to low temperature district heating, by the hand of Christian Holm Christiansen, Senior Consultant at the Danish Technological Institute (DTI), and RELaTED Project partner. Decarbonised district heating systems are already here. 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 presents some of the opportunities and challenges cities may encounter in their endeavour towards a sustainable and efficient energy system. It covers how to plan for the deployment of new DHC systems, as well as the extension and refurbishing [...]

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 [...]

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.

New posibilities for ultra-low temperature district heating in corporate district heating networks

Olga Macias, researcher in the field of energy eficiency in buildings in Tecnalia, explains the intervention developed by the RELaTED project in the demonstration site of Iurreta (Spain), in order to test the posibilites of the ultra-low temperature district heating systems in a corporate building complex. Tecnalia coordinates the RELaTED project which aims to develop an innovative concept of desentralized ultra-low temperature district heating networks. This new concept will be tested in four demonstrations sites, in Denmark, Serbia, Estonia and Spain. The Spanish project is located in Iurreta, in the North of Spain. This site is a policial base owned by the Department of Security of the Basque Goverment. The based consists on a total of thirteen buildings with diferent [...]

Metering and billing of consumption in ultra-low temperature district heating systems

In general, metering of district heating consumption in ultra-low temperature district heating (ULT DH) systems is not different from traditional district heating. However, when electricity is used to boost DHW temperature, this share of the DHW production is no longer metered by the district heating company, or must be metered separately by an additional electricity meter. This information has been extracted from the section 5 of the document D.2.2. Interconnection schemes for consumer installations. DOWNLOAD THIS DOCUMENT HERE >> Figure 3: principle of metering in ULT DH systems with electric booster In this case, there might be different ways to bill the consumer. One option is that the consumer is just billed the district heating consumption with usual [...]
