Natural Refrigerants in Heat Pumps: Pushing the Boundaries of Sustainability
Welcome to Issue 1/2025 of Heat Pumping Technologies Magazine!
We are excited to present the very first edition of Heat Pumping Technologies Magazine for 2025, dedicated to a crucial and timely theme: “Natural Refrigerants in Heat Pumps: Pushing the Boundaries of Sustainability.”
As the global urgency for sustainable solutions accelerates, the heat pump sector is evolving rapidly to meet the challenge. Natural refrigerants, including carbon dioxide (CO₂), ammonia, hydrocarbons, and water, are gaining significant momentum due to their low global warming potential (GWP) and minimal environmental footprint. In this issue, we explore how these environmentally friendly alternatives are redefining heat pump technologies, driving innovation, and shaping the future of sustainable heating and cooling.
We begin with the Foreword, titled “Natural Refrigerants in Heat Pumps: Pushing the Boundaries of Sustainability,” setting the tone for an in-depth exploration of how natural refrigerants are leading a transformation in the industry.
Our Column, “From Legacy to Leadership: District Heating in Eastern Europe as a Platform for Large-Scale Heat Pumps,” examines how district heating systems are becoming fertile ground for large-scale sustainable heat pump integration.
The Topical Section showcases a series of articles highlighting cutting-edge research, technological breakthroughs, practical case studies, and forward-looking policy frameworks aimed at accelerating the adoption of natural refrigerants:
- Beyond Climate Change: Sustainability Assessment of Heat Pumps and Refrigerants
- Oil Meets Cool: Inside the World of Lubricant-Refrigerant Properties
- Domestic Heat Pumps Using Hydrocarbons: Current Status and Market Overview in Europe
- Review of Heating and Cooling Applications Where Hydrocarbons Have Been Introduced as Refrigerants and Future Perspectives of Their Use
- Modeling Leaks of Flammable Refrigerants
In the National Market Section, we turn our focus to the Netherlands with an exclusive “Heat Pump Market Report,” offering valuable insights into one of Europe’s most dynamic markets for sustainable heating and cooling solutions.
This debut issue captures the drive, ambition, and innovation shaping the next generation of heat pumps. We invite you to dive in and discover how natural refrigerants are pushing the boundaries of what is possible for a more sustainable world.
Enjoy your reading!
