Abstract
This paper explores various combinations of electric heat pumps (EHPs), hydrogen boilers (HBs), electric boilers (EBs), hydrogen absorption heat pumps (AHPs) and energy storage technologies (electric and thermal) to assess their potential for matching heating and cooling demand at low cost and with low carbon footprint. A technology-to-systems approach is adopted, based on comprehensive thermodynamic and component-costing models of various heating technologies, which are integrated into a whole-energy system optimisation model to determine cost-effective configurations of heating and cooling systems that minimise the overall cost for both the system and the end-user. Case studies presented in the paper focus on two archetypal systems that differ in terms of heating and cooling demand and availability profiles of renewables (high PV vs high wind energy penetration). The proposed approach identifies efficient system-driven designs of low-carbon heating and cooling solutions, which will be affected by the characteristics of the system such as share of variable renewables, energy demand level and availability of competing flexibility options. Modelling results indicate the trade-off between investment costs and conversion efficiency of different technologies and highlight the role of electricity generation mix in choosing the cost-efficient portfolio of heating technologies. Capacities of different heating and cooling technologies are found to vary significantly depending on system properties such as the volume and diversity of heat demand and the availability profiles of renewable generation.
