Heat Energy

 

Space and water heating (excluding industrial process heat) account for about a quarter of UK energy consumption today, with demand of approximately 550-600 TWh per year. This TINA focuses on heat pumps, heat networks and heat storage as three key heat technologies that could play a key role in meeting UK and global heat demand in an emissions constrained future. Analysis suggests that these technologies could deliver anywhere from one-third to almost the entire UK heat demand by 2050. We estimate potential 2050 deployments levels of 70-240GW (100-340TWh) for heat pumps, 10-95GW (20-200TWh) for heat networks, and 6-190GW for heat storage.

Innovation in these heat technologies could reduce UK energy system costs by £14-66 billion to 2050, with heat storage also offering additional value by enabling other system adjustments. Innovation can also help create a UK industry with the potential to add £2-12 billion to UK GDP to 2050. Significant private sector investment in innovation, catalysed by public sector support where there are market failures, can deliver the bulk of these benefits with strong value for money.
