1 District Heating & Cooling Networks in the 2050 Energy System 11/10/2016 Carsten Petersdorff

2 The Energy System of 2050 The Energy system of 2050 will be the one that: emits low/no carbon in 2050 fits to increasing urbanisation is an integrated energy system, fully utilizing flexibilities & storage capacities provides minimal dependencies on fuel imports is affordable and supports economic prosperity of the EU. fotolia/kwest fotolia/anasirkhani fotolia/vege 2

3 Energy efficiency and low carbon sources are both needed to meet requirements of the energy system 2050 fotolia/dalmatin.o Strategy Strong energy efficiency measures lead to substantial energy savings Remaining demand will be still significant Increasing share of lowcarbon sources in the supply mix needed Source: Heat Road Map Europe (2013) Space heating in the EU-EE scenario from the Energy Roadmap 2050 report, the Deep Renovation scenario from Ecofys in Eurima Renovation Tracks study, and the new space heating demand assumed in the Heat Road Map Europe Energy Efficiency (HRE-EE) scenario. 3

4 What will the future role of district heating look like? How will DH&C develop together with strong reduction of demands in the buildings? What is the role of DH&C in delivering the RES solutions for high density city areas and villages? How would DH&C contribute as an integral part of energy system?

5 Diverse DH&C markets in the current situation Northern Europe: e.g. Denmark, Sweden; front runner, more than 50% of the citizens of the Northern countries in the EU are served by DH Central & Eastern Europe: long tradition, fossil-fuel based, change needed to become low carbon Western Europe: e.g. UK, France, Netherlands, quite low market penetration, detailed plans to start extending existing grids and constructing new networks In general change to low carbon systems is needed European Cities with DH&C systems Source: Heat Roadmap Europe Study (2013) 5

6 Learnings from Case Studies: coupling energy efficient buildings with modern DH&C networks Case study Torino, Italy Continued connection of renovated buildings into the existing DH network as it is the most convenient solution from end user perspective. DH provider adjusts to the changing market (decrease in heat demand) by shifting focus to providing additional services to customers. DH is seen as the only option to bring in renewables into the dense city landscape. Source: IREN Group (2014) ge%20and%20hydroelectric%20storage%20- %20CLARA.pdf 6

7 Learnings from Case Studies: coupling energy efficient buildings with modern DH&C networks (continued) Case study Nieuw Zuid, Antwerp, Belgium Successful integration of very low energy buildings to a newly developed DH network. DH provided by its versatility in the supply mix which can be designed and changed according to long term plans of the region. New development Synergies Heat Network CHP Strong involvement of city authorities, driven by its ambitions with respect to DH. City executed feasibility studies, took the decision about the energy standards and about the heating technology (DHC instead of a gas network). Source: 7

8 District Cooling District Cooling Currently, cooling is mainly produced by electricity-driven compression chillerscosts are hidden in the electricity bill. Space cooling demands are expected to rise towards District cooling has high potential in combination with efficient buildings as lower individual loads balance the higher flow rate and allow for the connection of more buildings. Case study Copenhagen, Denmark An example of well-established district cooling network with existing and new energy efficient building. Often district cooling is the only method that can support requirements within building regulations. Source: 8

10 DH&C offers a great potential to link electricity market with heat (and fuel) markets Increasing need for integration of energy networks: Thermal storages required to optimise the performance of heat networks; Flexibility can be increased via utilising resource diversity for heat sources; Flexibility via integration of heat networks with electricity grids Source: International Energy Agency (IEA) (2014) Linking Heat and Electricity Systems 10

11 Conclusions EU Energy & Climate goals require deep and cost effective emission reductions towards 2050 Transformation of building stock with substantially decreased demand is a key requirement. However, there will be substantial heat demand in future. The heat delivery services need to be adopted to enable greater share of renewable and recoverable heat energy sources into an integrated urban energy system. DH&C networks proves to be promising solution DH&C serve as flexible tools to bridge electrical and thermal energy systems, which will play an increasingly important role in achieving integrated, sustainable energy networks in the future The development of modern district heating systems in urban areas has a significant potential to contribute to integrated energy solutions 11
