Heating with Ice for Cost Effective Electrification, Resilience and Optimization

Building electrification using air-source heat pumps (ASHPs) is costly and requires a significant amount of space. Ice heating has the potential to reduce the capacity of ASHPs needed for full electrification by 50%, while also allowing for grid interactive peak shifting for added energy resilience and time-of-use carbon savings in order to meet decarbonization policies and local stretch codes. This thermal storage solution can dramatically reduce first costs, carbon emissions, and space required for full electrification of new construction and existing buildings.

Learning Objectives:

  • Identify how ice storage enables buildings to recover heat and electrify more efficiently.
  • Explore how ice storage can be coupled with familiar mechanical equipment to reduce capacity, space, and first cost for electrification.
  • Explain how ice storage can enable buildings to shift peak energy use for energy resilience and time-of-use energy cost and carbon savings.
  • Examine how federal incentives for thermal storage can offset capital costs and improve ROI.
