  1. 1. 1 Click to add title Decarbonising heat: networks, pumps or pipes? Robert Sansom – Imperial College UK energy system in transition: Technology, infrastructure & investment Edinburgh - 1st April 2014
  2. 2. 2 Click to add titleTowards decarbonising heat Maximising the opportunities for Scotland Four key challenges: • Decarbonising heat • Diversifying sources of heat • Reducing pressure on household energy bills • Seizing the economic opportunities
  3. 3. 3 Click to add titleDecarbonising heat Total final energy consumption in Scotland 2011 Source: DECC. (2013). Total final energy consumption statistics (Sub-national): 2011. Heat Electricity Transport Heat accounts for 47% of total CO2 emissions.
  4. 4. 4 Click to add titleSources of domestic heat Source: Scottish condition survey using 2012 data. Heat Electricity Transport
  5. 5. 5 Click to add titleHalf hourly heat demand Heat
  6. 6. 6 Click to add titleImpact of temperature on UK gas demand Heat is very temperature sensitive
  7. 7. 7 Click to add titleUK daily temperature annual duration curves
  8. 8. 8 Click to add titleFuture heat demand High Government Intervention and Uptake scenario • Very aggressive energy efficiency improvements • Significant electrification (>50%) of heat using heat pumps • Modest development of district heating • No storage heating TWh Domestic
  9. 9. 9 Click to add titleImpact on Scottish electricity infrastructure
  10. 10. 10 Click to add titleComparison of low carbon heat technologies 0 1 2 3 4 5 Running cost Deployment Performance Optionality Investment cost Flexibility Network impact Heat output Heat pumps District heating Electric storage heaters 5 = Good 1 = Poor
  11. 11. 11 Click to add titleSummary and conclusions • Decarbonising heat is essential to meet Scotland’s 2050 CO2target. • A transformation of Scotland’s heat sector is required. • There is considerable uncertainty in terms of costs, performance and deployment of heat technologies. • A “whole systems” approach is essential. • Heat storage provides substantial opportunities to support intermittent and inflexible generation. • Consumer engagement is crucial to deliver:  reductions in heat demand.  selection of heating technology.
