Heat pump technology has emerged as a pivotal solution for heating and cooling applications, leveraging renewable and waste heat sources effectively. This field is gaining momentum as the imperative to address climate change intensifies globally, with a marked increase in temperatures prompting national and regional carbon-neutral roadmaps. Heat pumps' central role in such strategies is underscored by their efficiency and potential for decarbonization. They are notably more effective than conventional heating systems like gas or oil furnaces since they transfer rather than generate heat. This mechanism significantly cuts energy consumption in buildings, which is crucial given that such consumption accounts for approximately 80% of a building's total energy use.

This Research Topic aims to explore the evolving efficiencies, applications, and significant role of heat pumps in energy decarbonization. The focus will be on how these systems align with global strategies to curb carbon emissions, facilitating a transition to renewable energy sources, and improving system performance even in less accommodating climates. We are particularly interested in research that addresses the technological advancements that enhance heat pump reliability and cost-effectiveness, contributing actively to their growing adoption.
