Heat Roadmap Europe 2050 : First Pre-study for the EU27
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This pre-study presents the findings concerning a considerable outlined expansion of the district heating sector within the current EU27 member states until 2050. Heat deliveries are presumed to grow by a factor of 2.1 until 2030 and by a factor of 3.3 until 2050.The current energy policy context is that the latest energy communication from the European Commission (Energy Roadmap 2050) contains only a very modest growth in the future for district heating systems and additional industrial heat use from industrial CHP plants. A small increase is foreseen for industrial demands, while heat deliveries to the residential and service sectors are expected to decrease. In total, the heat delivered is expected to increase by less than one per cent per year, giving a total increase of 20% until 2030 and of 40% until 2050.In this prestudy, more ambitious growth rates are assessed for district heating in the EU27 between 2010 and 2050. The chosen methodology in this pre-study contains a combination of hour-by-hour energy modelling of the EU27 energy system and mapping of local conditions, which is essential for district heating analysis. However, the link between these two actions has not been fully utilised in this pre-study due to the limited working time available: The mapping action has only indicated the input to the energy modelling action.

Renewable heating and cooling pathways – Towards full decarbonisation by 2050 – Final report
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- With the adoption of the EU Climate Law in 2021, the EU has set itself a binding target to achieve climate neutrality by 2050 and to reduce greenhouse gas emissions by 55 percent compared to 1990 levels by 2030. To support the increased ambition, the EU Commission adopted proposals for revising the key directives and regulations addressing energy efficiency, renewable energies and greenhouse gas emissions in the Fit for 55 package.The heating and cooling (H&C) sector plays a key role for reaching the EU energy and climate targets. H&C accounts for about 50 percent of the final energy consumption in the EU, and the sector is largely based on fossil fuels. In 2021, the share of renewable energies in H&C reached 23%. The decarbonisation of heating and cooling is addressed across several directives and regulations at EU level.The aim of this study is to support the analytical basis for the development and implementation of policies to ensure a seamless pathway to the full decarbonisation of the heating and cooling sector by 2050 in buildings and industry.

Tidskriftsartikel (refereegranskat)abstract
- Six different strategies have recently been proposed for the European Union (EU) energy system in the European Commission’s report, Energy Roadmap 2050. The objective for these strategies is to identify how the EU can reach its target of an 80% reduction in annual greenhouse gas emissions in 2050 compared to 1990 levels. None of these scenarios involve the large-scale implementation of district heating, but instead they focus on the electrification of the heating sector (primarily using heat pumps) and/or the large-scale implementation of electricity and heat savings. In this paper, the potential for district heating in the EU between now and 2050 is identified, based on extensive and detailed mapping of the EU heat demand and various supply options. Subsequently, a new ‘district heating plus heat savings’ scenario is technically and economically assessed from an energy systems perspective. The results indicate that with district heating, the EU energy system will be able to achieve the same reductions in primary energy supply and carbon dioxide emissions as the existing alternatives proposed. However, with district heating, these goals can be achieved at a lower cost, with heating and cooling costs reduced by approximately 15%. © 2013 Elsevier Ltd.

Heat Roadmap Europe 2050 : Second Pre-study for the EU27
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Many strategies have already been proposed for the decarbonisation of the EU energy system by the year 2050. These typically focus on the expansion of renewable energy in the electricity sector and subsequently, electrifying both the heat and transport sectors as much as possible. In these strategies, the role of district heating has never been fully explored system, nor have the benefits of district heating been quantified at the EU level. This study combines the mapping of local heat demands and local heat supplies across the EU27. Using this local knowledge, new district heating potentials are identified and then, the EU27 energy system is modelled to investigate the impact of district heating. The results indicate that a combination of heat savings, district heating in urban areas, and individual heat pumps in rural areas will enable the EU27 to reach its greenhouse gas emission targets by 2050, but at a cheaper price than a scenario which focuses primarily on the implementation of heat savings.

Mapping local European heat resources : a spatial approach to identify favourable synergy regions for district heating
- 2012
-
Konferensbidrag (refereegranskat)abstract
- A major setback in standard generic energy modelling is that national conditions constitute the basis for analysis. By such an approach, heat and energy assets, demands, and distribution structures are viewed from an aggregated perspective not permitting insight into unique local circumstances and conditions. As a consequence, genuinely local synergy opportunities, e.g. recovery and utilisation of excess heat from various activities and sources by distribution in district heating systems, are often ignored or overlooked in generic forecasts.The ambitious European targets to increase energy efficiency in future power and heat distribution and use acts as a force to address local conditions in a more systematic and thorough sense than previously elaborated. Increased utilisation of local heat assets and recovered excess heat from local activities, to provide space and tap water heating in residential and service sectors, can replace and thus substitute large shares of natural gas and electricity currently being used to satisfy low temperature heat demands. Spatial screening and identification of local conditions throughout Europe, by use of NUTS3 regions as analytical level of reference, can disclose favourable synergy regions by combining information on local heat assets and demands, and hence provide additional and pivotal information to energy modellers.In this study, local conditions such as excess heat from thermal power generation plants, Waste-to-Energy incineration facilities, energy intensive industrial processes, and renewable heat assets (geothermal and solar), are depicted together with heat demand concentrations, using GIS based spatial information, to visualise the possibilities of mapping local European heat resources.
