With energy costs on the rise and the global push toward decarbonization, heat pumps have emerged as a key player in our pursuit of Net Zero – especially in the industrial sector.
How Heat Pumps Work
Heat pumps, contrary to their conventional counterparts, heat or cool a space through the transfer of heat rather than through combustion. In the winter, it works to extract heat from external sources such as the air, ground (geothermal) or water and transfers it into the built environment to warm it up. In the summer, the process works in reverse, removing heat from the indoors and releasing it out.
Challenges to Widespread Heat Pump Adoption
While heat pumps have been widely adopted in residential settings, large-scale industrial and commercial operations have been slow to transition due to high upfront costs, infrastructure constraints and, particularly in Canada and northern U.S. states, performance in extreme temperatures.
Optimal heat pump performance occurs when there is minimal temperature difference between the indoors and out. In harsh winter climates, extracting heat from the external environment can be challenging. Additionally, frost build-up on the heat pump coils can trigger an energy intensive defrost cycle. Ultimately, introducing heat pumps in extreme weather conditions was previously not ideal.
Recent Innovations and Breakthroughs
The next-generation of cold climate heat pumps (CCHPs) can now operate effectively at temperatures as low as -30°C, thanks to variable-speed compressors and improved refrigerants. When strategically integrated with smart controls and artificial intelligence, heat pumps can optimize energy usage, reduce operational costs and improve energy management in colder climates and in industries that rely on large-scale heating and cooling systems.
Industrial-grade heat pumps capable of reaching temperatures above 100°C are also now available, making them viable replacements for fossil fuel-based heating in sectors such as manufacturing, food processing, and district energy systems. Industries that depend on high-temperature heating, such as chemical production and metallurgy, are now exploring hybrid heat pump systems that integrate with existing boilers to reduce energy consumption. These systems allow for a gradual transition to sustainable energy sources without disrupting critical operations.
No One-Size-Fits-All: Optimizing for Your Business
While heat pumps provide a promising route to Net Zero for North America, there is no one-size-fits all solution.
