Joint Research Centre Technical Report – Assessment of heating and cooling related chapters of national energy and climate plans (NECPs) in EU Member States

JRC just published its assessment of the chapters of EU Member States’ National Energy and Climate Plans (NECPs) dealing with the heating and cooling sector. The analysis showed that most Member States are less ambitious in decarbonising their H & C sector in comparison with the power sector. JRC issued the following recommendations for drafting the heating and cooling sector goals and measures in the NECPs:

1) increasing the level of ambition, given the important role of this sector in fulfilling the EU’s climate and energy goals;

2) providing more information on the constraints that caused not meeting the requirement of reaching the renewable energy targets in the heating and cooling sector, with a detailed plan with measures to close the gap;

3) identifying and providing trajectories for the main renewable energy technologies contributing to reaching the sectorial target

4) clarifying the contribution of CHP to targets, for example that co-generated heat from natural gas CHP plants should not be considered waste heat and, therefore, cannot be counted towards the target specified in Article 23 of Directive (EU) 2018/2001 on the promotion of the use of energy from renewable sources.

District heating in the Western Balkans – we need clean, modern heating that works for everyone, for the long term

Achieving decarbonisation goals is not possible without reforming and modernising the district heating sector. Despite being an important source of space heating, district heating efficiency in the Energy Community is still at a low level. In its blog and video, Bankwatch Network addressed the issues that district heating systems in the Energy Community are facing and emphasised the need to start planning the transformation of district heating as soon as possible.

White paper on transforming district heating in Ukraine: assessment and recommendations

Ukraine is currently conducting deep reforms of district heating (DH) to address the sector’s challenges. Non-reflection of operating and investment costs in the DH tariffs have made it difficult if not impossible for companies to invest in modernization of the networks. Being closely interlinked with the natural gas sector, DH sector regulations should align with the upcoming natural gas market liberalization.

USAID with its Energy Security Project provides significant support to the reform process. This document describes key challenges faced by Ukraine’s DH sector and provides recommendations on developing and implementing a comprehensive 10-year strategy that can lead to loyal and satisfied customers, a sustainable and self-sufficient DH sector and an efficient and environmentally friendly heat supply market.

Options for large-scale installation of individual heat substations based on international best practices

A means to improve energy efficiency in the district heating sector is installing individual heat substations (IHSs) in buildings connected to the district heating network. IHSs allow for building-level temperature regulation and can significantly reduce heat consumption and overheating. IHSs are nearly universal in Western European countries with developed district heating systems. These investments have improved service quality and energy efficiency and are generally found to be cost-effective. The report provides the financial and legal solutions for large-scale deployment of IHSs in Ukraine, building on analysis of international best practices in three Member States – Poland, Czechia and Latvia, as well as United Kingdom.

European Commission issues Recommendation on content of comprehensive assessment of DHC potential

The Contracting Parties of the Energy Community have an obligation, based on Article 14 of the Energy Efficiency Directive (EED), to conduct a comprehensive assessment of the potential for high-efficiency cogeneration and district heating and cooling, which must include all the elements referred to in Annex VIII of the EED. The obligations to deliver the first comprehensive assessment and notify the Energy Community Secretariat were due by 30 November 2018.

Annex VIII of the EED was amended by the Commission Delegated Regulation (EU) 2019/826 of 4 March 2019, which simplifies the requirements for the assessments and aligns them with the legislative acts of the Clean Energy Package. e. The European Commission, after analysing the first set of comprehensive assessments of Member States, delivered this recommendation to further instruct the Member States on the updated requirements of the content of the comprehensive assessments. These instructions can guide Contracting Parties in designing their comprehensive assessments.

JRC’s Study on Integrating renewable energy and waste heat in district heating

Based on a holistic case studies analysis of 8 efficient district heating and cooling (DHC) systems in different EU Member States (Denmark, France, Germany, Italy, Lithuania and Spain), the study investigates the design and operation of DHC systems mainly supplied by renewable energy sources and (excess) waste heat and cold sources. The study aims at identifying the key success factors enabling the integration of those sources, and drivers and conditions for their replicability in other cities and communities. Finally, it suggests some potential policy guidelines to support the integration of local and low-carbon energy sources through DHC. Read more in the JRC’s study.

A carbon pricing design for the Energy Community

The Energy Community has commissioned Kantor and E3 M to prepare a study proposing a carbon pricing mechanism for the time horizon until 2040, suitable for the decarbonisation of the power and district heating sectors in the Contracting Parties. The PRIMES-IEM model was used to quantify five stylized scenarios for the introduction of carbon pricing in the power and district heating sectors in each CP: 1) Baseline Scenario, 2) Full Carbon Pricing and Market Fragmentation Scenario, 3) Gradual Carbon Pricing and Market Fragmentation Scenario, 4) Full Carbon Pricing and Market Integration Scenario and 5) Gradual Carbon Pricing and Market Integration Scenario.

Fossil fuels being by far the dominant energy source in district heating in the Energy Community, the study investigates the impact of each scenario on heat prices. The study puts forward a proposal for a Cap and Trade policy option in the power and district heating sectors, rather than a carbon tax, and also recommends the Gradual Carbon Pricing and Market Integration Scenario as the optimal approach for the Energy Community. Read more about the scenarios, policy options and recommendations in the Report.

JRC‘s Technical Report on Decarbonising the EU heating sector

The heating and cooling sector has been recognised as key for achieving decarbonisation and energy efficiency targets. The Joint Research Centre has presented two clean transition pathways for the heating sector in EU Member States, namely electrification of heat and efficient heat and power production and district heating networks. The study finds that electrification of heat, by replacing all current fossil-fuelled heat generation technologies by heat pumps, would reduce by 16% the combined emissions of the heat and power sector. The implementation of the second pathway concludes that if all current or future steam based power plants were operating on CHP mode together with district heating networks (including thermal storage), the overall efficiency of the energy system would increase significantly. Read more about decarbonising the EU heating sector in the JRC’s technical report.

IRENA’s Innovation outlook: Thermal energy storage

The report expects the global thermal energy storage (TES) market to triple in size by 2030. TES use in district heating and cooling effectively decouples demand from supply, allowing energy to be stored on a seasonal basis. The resulting flexibility allows far greater reliance on variable renewable sources, such assolar and wind power. District heating already incorporates sensible heat technologies such as tank TES (or TTES) and underground TES (or UTES). Water tank TES (or WTTES), already widely used in buildings, is also coming into increasing use for solar thermal plants in the mining, food and textile industries. The report includes 12 case studies illustrating several TES technologies and their impact on the energy sector.

EU Strategy for Energy System Integration

In June 2020, the European Commission adopted the EU Strategy for Energy System Integration. The Strategy emphasises the role of the district heating systems in sector coupling. The heating sector can be coupled with the power sector through the roll-out of heat pumps as a way for building electrification. Moreover, to ensure that local energy sources are sufficiently and effectively used, waste heat from industrial sites should be reused, on-site or trough district heating and cooling networks.
