Four key challenges:
• Decarbonising heat
• Diversifying sources of heat
• Reducing pressure on household energy bills
• Seizing the economic opportunities

Click to add title Summary 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.
