Urban waste heat recovery, in which low temperature from urban sources is recovered for use a district network, has great deal of potential helping to achieve 2050 climate goals. For example, data centres, metro systems, public sector buildings and water treatment plants could be used supply 10% Europe’s demand. Despite this, at present, recovery not widespread an immature technology. Based on interviews with stakeholders, investors interested green investments, experience demonstrator...

There are currently several challenges facing the Swedish district heating (DH) industry. To address these challenges, new business models needed. One such model involves widespread use of Heat Pumps (HPs) in DH networks (DHN). However, HPs compete with other more conventional heat sources and their inclusion is not yet common. In this study, efficiency gains impacting cost CO2 emissions for HP inclusions compared to current state affairs different concepts developed discussed a typology...

Flexibility can support the energy transition and improve efficiency of heat supply to buildings. This study tests price models for inclusion pumps (HPs) in district heating network (DHN). Various were tested two cases Sweden. In Sweden, DH companies are increasingly confronted with instances where building owners invest a HP only use when it is too cold function efficiently. poses challenges due high costs associated peak load production. Potential gains HP-DHN flexibility investment...

Approximately 1.2 EJ of energy are potentially available for recovery each year from urban heat sources in the EU. This corresponds to more than 10 percent EU’s total demand and hot water. There are, however, a number challenges be met before waste can performed on wide scale. paper focuses non-technical issues related is written basis opinions gathered stakeholders field. Three focused upon. First, important barriers scale identified, where applicable, recommendations made regarding how...

Against the background of accelerating climate change, this paper examines to which extent sustainable infrastructure finance can effectively contribute European heat transition as a part "Great Transformation" towards neutral economy and society. Since building sector is responsible for approx. 35% EU's carbon footprint, district heating cooling networks provide an efficient technology decarbonizing energy supply buildings. New allows hot water generation that combustion free. A large-scale...

The Swedish district heating sector is successfully transitioning to a low-carbon energy system. industry has expanded since the 1950s and currently meets more than half heat demand. market was deregulated in 1996, thereafter, companies have been exposed an increasing number of challenges related technology, institutional factors market. Since municipal ownership dominates, must manage these ensure future competitiveness. However, theory suggests that business change difficult when current...

This paper addresses the implications on business model of district heating companies technology shift targeting lower temperatures in distribution network. Lower are valuable, since heat supply to low-energy buildings with low grid losses is facilitated. In addition, low-temperature sources can be integrated into an efficient energy system, improving environmental performance industry. opens a window opportunity update logic sector, allow diversification value proposed customers and closer,...

Excess heat is generated from different industrial processes and urban infrastructure (sewage water, transport, datacentres buildings). Thirty-five percent of the European energy demand for heating cooling could be met by excess heat. Today, however, this reserve barely exploited. There are known barriers to recovery but limited information on stakeholder interactions in early stages collaborations successful collaborations. Sweden world champion terms into district systems, country has a...

Use of low-temperature heat sources in district heating (DH) systems is gaining attention as a climate mitigation measure. Urban excess (UEH) from data centres, metro stations, sewage and service sector buildings' cooling system belongs to these sources. The use UEH affects energy supply costs. We analyse the long-term impacts utilizing four through dynamic modelling systems. study draws on real cases cities addresses local conditions. results show that utilization can contribute increased...

A large amount of low-temperature urban excess heat sources are available to play a fundamental role in the decarbonisation heating sector and present future District Heating Networks (DHNs). This work, context ReUseHeat project, defines performance assessment procedure applied four advanced recovery solutions from data centres, hospital cooling systems, sewage water networks underground stations. Key Performance Indicators defined allow for integral evaluation line with Smart Cities...

Abstract Background District Heating (DH) is a technology that provides heating and domestic hot water to buildings an important for supporting the European energy transition. As such systems increasingly resort renewable heat sources waste heat, it even more they operate in most efficient way possible. DH companies have access primary network of which can impact system performance. To maximize efficiency system, however, at building level, known as secondary also efficient; otherwise,...

(1) Background: To support the energy transition in Europe, EU has launched multiple initiatives. Supporting “Green Deal” is New European Bauhaus (NEB). District heating and cooling (DHC) an important part of a decarbonized system, its role been stressed by EU. In this paper, DHC is, for first time, reviewed assuming NEB principles. (2) Method: literature review combined with three cases was used collecting data. (3) Results: It confirmed that strong sustainability values. also identified...

Industrial heat recovery can be used in district heating systems. It is a possibility to make use of that otherwise lost. Increased usage industrial reduces the need for fuel combustion lowering green-house gas (GHG) emissions, such as CO2. companies can, however, move or close down activities. This apprehended risk and lowers interest invest recovery. In Swedish systems, recoveries have been undertaken since 1974. Today, active about seventy leads question how risky it is, companies, engage...

This study has been undertaken to understand whether business models for heating, cooling and hot water can be categorized as circular. The addresses the case of new, combustion-free technology by resorting low-temperature district energy. Such systems necessitate smart infrastructure with efficient demand supply matching ensuring most cost-efficient use heat over time. By studying 10 cases in a research project period stretching across 3 years, it is identified that all display circular...

Low temperature district heating is recognized as a key technology for the (cost-) efficient integration of renewable energy and waste heat sources in our systems. Several studies indicate that deployment local schemes measure reaching politically set climate goals. Further, implementation low systems are recommended taking maximum advantages synergies with other sectors decarbonization sector. Within IEA DHC Annex TS2 project already realized community system concepts well planned or...

Urban heat sources from urban infrastructure and buildings could meet ~10% of the European building heating demand. There is, however, limited information on how to use them. The EU project ReUseHeat has generated much existing knowledge waste recovery implementation. Heat a data center, hospital water were demonstrated. Additionally, stakeholders, risk profile, bankability business models. is characterized by high potential, competitiveness compared other alternatives, avoidance GHG...
