Industrial decarbonization: the growing role of high-temperature heat pumps
High-temperature heat pumps prove to be strategic for reducing emissions and energy consumption in industrial processes.
In the process of decarbonizing industry , one of the most complex issues concerns process heat. Many production sectors, in fact, require high temperatures, which are still predominantly generated using fossil fuels. In this context, high-temperature heat pumps (HTHPs) are emerging as one of the most promising solutions for reducing emissions and energy consumption in industrial processes.
According to the new technical brief published by the International Institute of Refrigeration (IIR), these technologies represent a strategic element to accelerate the electrification of industrial heat and promote the use of renewable energy in production processes.
From heat recovery to high-temperature industrial processes
High-temperature heat pumps are designed to provide thermal energy above 80°C , in some cases reaching up to 200-300°C . This allows them to be used in numerous industrial applications where heat is an essential component of the production process.
The main areas of application include:
- food industry
- textile
- paper mill
- chemistry
- plastics processing
One of the most interesting aspects is the possibility of recovering waste heat from industrial processes or infrastructure and reusing it efficiently. This approach allows for reducing fossil fuel consumption and improving the overall energy efficiency of the plants.
An increasingly mature technology
In recent years, HTHPs have undergone significant evolution, both technologically and in terms of application. Today, commercial systems with high levels of maturity are available, capable of covering power outputs ranging from a few kilowatts to 100 MW.
The growing interest in these solutions is also confirmed by the increase in research and development activities dedicated to high-temperature industrial heat pumps.
At the same time, energy performance also improves : HTHPs allow the production of more thermal energy than the electrical energy consumed, making them an increasingly competitive solution compared to traditional systems based on fossil fuels.
Refrigeration, energy recovery and new industrial scenarios
For the HVAC/R sector, the growth of high-temperature heat pumps confirms an increasingly evident trend: the convergence of refrigeration, energy recovery and industrial heat production.
HTHPs share many of the same technological logic as refrigeration, from thermodynamic cycles to refrigerants used, and energy efficiency management. This makes the HVAC/R sector a key player in the development of these solutions.
Looking ahead, the integration of heat recovery, industrial heat pumps, thermal storage, and renewable energy could redefine the way energy is managed in production processes, transforming heat from a simple operational requirement into a strategic lever for the energy transition.

High-temperature heat pumps are playing a central role in industrial processes requiring heat between 80°C and over 150°C, such as the food, pharmaceutical, chemical, and paper industries. In these sectors, they allow partial or complete replacement of gas and steam boilers, leveraging electricity and heat recovery. From a design perspective, they are becoming a key solution for reducing emissions and fossil fuel consumption while maintaining operational continuity and energy efficiency.
Compared to traditional fossil fuel systems, high-temperature heat pumps allow waste energy to be recovered and converted into usable heat with high COPs, reducing energy consumption and emissions. Furthermore, they improve the system's energy flexibility, especially when integrated with renewable sources and storage systems. This approach allows companies to reduce their exposure to the volatility of fossil fuels and improve the overall sustainability of their production processes.
In the medium term, rapid evolution is expected in compression technologies and natural refrigerants, with systems capable of reaching ever higher temperatures and broader industrial applications. Growing regulatory pressure for decarbonization will accelerate investment in these solutions, favoring standardization, cost reduction, and greater integration with renewable energy networks. For the industrial HVAC/R sector, high-temperature heat pumps represent one of the most strategic technologies in the energy transition.
