Summary

Heating, ventilation, air conditioning, and refrigeration (HVAC&R) in buildings is responsible for a significant portion of the U.S. primary energy consumption. To address energy and climate issues, technological breakthroughs for next generation HVAC&R technologies are expected to enable high energy efficiency and decarbonization targets. Among the novel technologies, the chemical looping heat pump (CLHP) has been proposed as a promising and valuable alternative to conventional vapor compression (VC) systems. Previous analyses have shown that CLHPs can achieve 20-30% performance improvements with significant cost savings opportunities. However, there has been no direct comparison of economics between CLHP and existing technologies.
In this work, a modeling framework to estimate levelized cost of energy (LCOE) for space conditioning applications is developed to enable a direct early-stage comparison of emerging technologies with conventional VC systems. The LCOE is composed of two contributions, levelized operating expenditures (OPEX) and levelized capital expenditures (CAPEX), that are helpful in understanding the influence of key factors such as unit utilization (annual cooling and heating delivered, kWht/yr) and price of electricity (POE, $/kWhe). The LCOE model was used to evaluate various scenarios (e.g., different utilizations, utility costs, and unit performance improvements) with the goal of determining target markets for initial CLHP products across the United States.
