Project Summary

There is some evidence that hybrid heating systems - heat pumps coupled with conventional technologies - can achieve significant carbon reductions when actively-controlled. There is a need, however, to better understand the interdependencies between this hybrid heating and the wider energy system of different vectors at different scales. Also, the consequential impacts of hybrid heating on network constraints and regional, time-varying, marginal carbon emissions needs to be identified. This project addresses these by soft-linking dispatch models across scales and vectors with carbon analysis to examine the opportunities and costs of emissions-led dispatch of hybrid heating.
