3 Motivation Energy Road Map 2050 (EU commission) Road Map 2050 (McKinsey et.al) The energy report – 100% renewable energy by 2050 (WWF) Energy Technology Perspectives 2010 (IEA) World Energy Outlook (IEA) Deciding the Future – Energy Policy Scenarios to 2050 Consensus/general: Combined heat & power (CHP) and district heating (DH) are important Consensus/general: Combined heat & power (CHP) and district heating (DH) are important The European Commission in the Energy Roadmap 2050 communication: An analysis of more ambitious energy efficiency measures and cost- optimal policy is required. Energy efficiency has to follow its economic potential. This includes questions on to what extent urban and spatial planning can contribute to saving energy in the medium and long term; how to find the cost-optimal policy choice between insulating buildings to use less heating and cooling and systematically using the waste heat of electricity generation in combined heat and power plants.

7 Showing DH benefits in 2 steps Step 1: (Energy Efficiency) -Increasing DH to 30% then 50% -Increasing CHP -Using Oil/Natural gas in CC-CHP Step 1: (Energy Efficiency) -Increasing DH to 30% then 50% -Increasing CHP -Using Oil/Natural gas in CC-CHP Step 2: (Utilise waste and RE sources) -Industrial waste heat -Waste incineration -Geothermal heat -Large-scale Solar Thermal Step 2: (Utilise waste and RE sources) -Industrial waste heat -Waste incineration -Geothermal heat -Large-scale Solar Thermal

8 Future: EU Energy Roadmap 2050 Completed for the European Commission in 2011, by the National Technical University in Athens Presents 6 energy scenarios for the EU27: Reference: Business-as-usual CPI: Updated business-as-usual EE CCS Nuclear High RE

9 2030/2050 Modelling EU CPI PRIMES Data 2030 & 2050 Model District Heating Alternatives 2010 = 12% DH 2030 = 30% DH 2050= 50% DH Results (PES, CO2, Costs) EU Energy Roadmap 2050 Current Policy Initiatives (CPI)

10 HRE1 Conclusion: 50% DH and CHP Decrease primary energy supply and especially fossil fuels and CO2 emissions Decrease annual costs of energy in Europe by approximately 14 Billion in 2050 Create additional 220,000 jobs over the period Further integration of RES LESS FUEL LESS MONEY MORE EU JOBS MORE RE

11 Cost and Jobs: Saved fuel costs of annual approx. 30 Billion EUR in 2050 In total cost are reduced by 14 Billion EUR in 2050 Additional investments of a total of 500 billion EUR Additional jobs from to 2013 to 2050: 8-9 million man-year in total Approx. 220,000 jobs.

12 Future: EU Energy Roadmap 2050 Completed for the European Commission in 2011, by the National Technical University in Athens Presents 6 energy scenarios for the EU27: Reference: Business-as-usual CPI: Updated business-as-usual Energy Efficiency (EU-EE) Carbon Capture & Storage Nuclear High Renewable Energy HRE2: Is district heating a good idea if we implement a lot of energy efficiency in the buildings?

13 Energy Modelling EU-EE PRIMES Data 2030 & 2050 Model District Heating Alternatives 2010 = 12% DH 2030 = 30% DH 2050= 50% DH Results (PES, CO2, Costs) EU Energy Roadmap 2050 Energy Efficiency (EE)

14 Key Measures in EU-EE Scenario High renovation rates for existing buildings due to better/more financing and planned obligations for public buildings (more than 2% refurbishment per year) Passive houses standards after 2020 Obligation of utilities to achieve energy savings in their customers' energy use over 1.5% per year (up to 2020) Strong minimum requirements for energy generation, transmission and distribution including obligation that existing energy generation installations are upgraded to the

15 EU-EE Scenario Heat Demand Concerns Hot water demand decreases by 50% between 2010 and 2050 Specific Heat Demands reduce by 70% between 2010 and 2050

16 EU-EE Scenario 63% Drop in Heat Demands Cost B300/year

17 HRE-EE Hot Water Growth = +16% Residential and non-residential buildings is expected to grow by 32% and 42% respectively between 2015 and 2050 Population will grow by 3.2% between 2010 and Individuals are likely to take more showers and baths in the future than they do today. People are not expected to live with one another as much in the future. At present, there are regions in Europe where the use of hot water is limited due to technical and financial limitations.

18 HRE-EE Space Heating = -47%

19 Implementing District Heating 1.Individual boilers are replaced by district heating: 30% in 2030 and 50% in 2050 Individual heat pumps are not replaced 2.Individual cooling units are replaced with district cooling. 10% in 2030 and 20% in 2050 Natural cooling and absorption heat pumps are both used.

20 Heat Demand by Source

21 Implementing District Heating 3.New DH production facilities are constructed: CHP, boilers, heat pumps, and thermal storage. 4.Additional resources can now be utilised by the district heating network: Industrial surplus heat: 100 TWh/year Direct geothermal heat: 100 TWh/year Waste incineration: 150 TWh/year Large-scale solar thermal: 100 TWh/year Wind power for large-scale heat pumps: 65 TWh/year

28 Case Study: Århus

29 District heating is an attractive solution in areas with a high heat density District heating can be seen as an efficiency measure similar to reductions in heat demand, because it enables the use of fuels in a more efficient way Heat reductions in buildings can be combined with district heating so that it is competitive with individual solutions Conclusions

30 Conclusions (1) If we continue under a business-as-usual scenario, then district heating can: Reduce the PES Reduce the CO2 emissions Reduce the costs of the energy system Use more renewable energy

31 Conclusions (2) If we implement a lot of energy efficiency measures, then district heating will: Meet the same goals, ie: Utilise the same amount of fossil fuels Enable the same CO2 emission reductions Cost approximately 10% less
