Energy price assessment associated with District Heating in Europe

The energy price assessment provides a review of the fuel types and their costs for the main heat production systems and primary energy sources associated with District Heating (DH) systems in Europe. Within this study, a review of heat production technologies and fuels is presented where the present, medium, and long-term energy costs for district heating networks are identified. Photograph: Flo Dnd in Pexels. The 4th generation District Heating and ULTDH have shown to be a highly efficient, environmentally friendly, and a cost-effective solution for heating and cooling. But to achieve this, conversion of DHNs is needed. To facilitate the conversion towards ULTDH, the RELaTED project has developed an innovative concept of decentralized ULTDH networks, which allows for [...]

Inaventa Solar starts a new project based on the results of its collaboration with RELaTED

The Norwegian manufacturer of solar collectors Inaventa Solar has recently started a new project, titled DisolBat (distributed solar and “blue batteries”), which builds on the results of its international collaboration with RELaTED project. Editor’s Note: This article was previously published at Inaventa Solar website. Work on RELaTED has led to the identification of innovative technical solutions for solar district heating. However, effective business models for the deployment of these solutions have not yet been established. Developing business models that take into account contributions along the entire value chain will therefore be the primary focus of DisolBat, which has been granted the maximum amount of funding available from the Research Council of Norway. Collaboration with the district heating industry Inaventa Solar's [...]

WEBINAR: Solar energy solutions for decarbonizing ULT DHC

How did the RELaTED pilot site in Denmark use solar power to deliver heat on the ULT DHC network? How can it help foster the EU renovation wave? Watch the recording to know it all. The EU Renovation wave, initiated in October 2020 by the European Commission, has targeted heating and cooling as a key sector in accelerating the renovation rate of buildings in Europe to notably cut CO2 emissions. One of the main aspects is to support the penetration of renewable energy sources (RES) in heating and cooling, including for district heating and cooling (DHC) networks. Solar energy appears to be a great technology for this aim. Its incorporation on existing DHC networks is a solution tested notably in [...]

NIBE’s new solutions for heating will test the posibilities of ULTDH in a building complex in Spain

The Swedish manufacturer NIBE recently sent to Spain some special developed heat pumps and hydraulic modules that will contribute to transform a district heating network into an ultra-low temperature network. These components and solutions will heat and cool two buildings in a corporate building complex in Iurreta, Spain, owned by the Basque Government. This building complex is defined as a demonstration site within the Horizon 2020 project RELaTED. The Swedish manufacturer of intelligent solutions for heating and control NIBE recently sent over to Iurreta, in northern Spain, some special developed components that will contribute to transform the district heating network onwned by the Basque Goverment into an ultra-low temperature network. Specifically, the shipment contained 3 special developed heat pumps, where [...]

An innovative solar system will soon be installed in a building complex in Spain

The solar collectors from Inaventa Solar will deliver energy for heating and domestic hot water to a building complex in Spain, owned by the Basque Government. This campus area is defined as a demonstration site within the Horizon 2020 project RELaTED, where the possibilities of ultra-low temperature district heating systems in corporate building complexes are being tested. Editor’s Note: This article was previously published at Inaventa Solar website. Photo: Inaventa Solar. A new solar system is on its way from the factory of the Norwegian manufacturer of solar collectors Inaventa Solar at Jevnaker to Iurreta in northern Spain. The solar collectors will be installed as a building-integrated solution in one of the south-facing facades of a larger building [...]

Energy improvement districts in the Basque Country

The RELaTED project deploys a decentralised, Ultra-Low Temperature district heating network concept. In RELaTED, every single building is converted into an energy node, where bi-directional heat exchange is allowed between the network and the building. One of the pilots of the project is located in Iurreta, in the Basque Country (Spain). This demonstration site will showcase the viability of the technology and the feasibility of DH, even in southern Europe. AUTHORS: Jesús M. Casado and José R. López - Ente Vascode la Energía - international@eve.eus District Heating (DH) systems are one of the most energy-efficient heating systems in urban environments, with proven reliability. When combined with renewable and waste heat sources, DH becomes an even higher efficient solution to decarbonise [...]

The Spring Edition of the FEDARENE Info includes information on RELaTED project

The 2021 Spring Edition of the FEDARENE Info is out. This edition -focuses on District Heating and Cooling- includes information about the RELaTED project and the progress made on its concept. Heating and cooling drive half of the energy consumption in Europe. However, more than two-thirds of demand is met with fossil fuels. Changing the conventional fossil paradigm in heating and cooling is essential for reaching the EU decarbonisation goals. District heating is one of the most promising options to decarbonise the heating sector and urban environments in general and is therefore crucial to reach European and global climate goals. Yet, several EU Countries are still facing challenges in implementing this technology: old and inefficient infrastructure, the unreliability of supply, loss of consumers, etc. [...]

Two approaches; one happy district heating & cooling network in Tartu, Estonia

Heat production technologies for district heating are only as efficient as the network they serve. Even if a heat plant is operating at 100% efficiency, heat loss due to the poor thermal insulation of buildings will create an “efficiency” ceiling that improvements at the heat production level cannot overcome. It would be as if a person were trying to heat their home in the winter with all the windows open. This analogy highlights one the biggest challenges for transitioning to ultra-low temperature district heating1 (ULTDH); How can a district heating (DH) operator improve the thermal efficiency for buildings they do not own? AUTHOR: Richard Karl Henahan – Research Analyst at the Institute of Baltic Studies. For the RELaTED project, the [...]

The desing of Triple Function Substations in combination with RELaTED technologies

Ultra-Low temperature district heating introduces multiple benefits at network level, as the reduction of heat losses and the improvement of heat generation efficiency. ULTDH also facilitates the integration of low temperatures renewable energy sources and waste heat into the district heating network. Renewable heat sources as solar thermal and heat pumps can be coupled to the district heating network and the buildings through specially designed district heating substations. Some images of the Microbooster and BILTST demonstration in Taastrup, Denmark. During the development of the RELaTED project, several Triple Function Substations (3FS) have been evaluated and designed. Those were investigated in different versions, connection schemes configurations and operating modes depending on the district heating characteristics, the building types and [...]
