Industrial heat and electrification: high-temperature heat pumps gain ground

In the process of decarbonizing industry , one of the most complex issues concerns the production of high-temperature heat. Many industrial processes continue to rely on fossil fuels to generate thermal energy , especially in energy-intensive sectors where heat needs represent a significant portion of overall consumption.

In this scenario, high-temperature heat pumps (HTHPs) are emerging as one of the most exciting technologies for accelerating electrification and energy efficiency in industrial processes . According to a new technical brief published by the International Institute of Refrigeration (IIR), these solutions could play a central role in reducing industrial emissions through the use of renewable electricity and heat recovery .

From heat recovery to energy-intensive industrial processes

High-temperature heat pumps are designed to provide thermal energy above 80°C , reaching up to 200-300°C in some applications. This allows the technology to be used in various industrial processes that require large amounts of continuous heat.

Among the main application areas the following stand out:

• food industry
• paper mill
• textile
• chemistry
• plastics processing

One of the most interesting aspects is the possibility of recovering waste heat from production processes and reusing it efficiently . In this way, HTHPs not only reduce fossil fuel consumption, but also harness thermal energy that would normally be wasted.

An increasingly mature technology

In recent years, high-temperature heat pumps have undergone significant developments, both technologically and in terms of application. Today, commercial systems are available that can handle very high power outputs and temperatures that were previously difficult to achieve with electrical technologies.

The IIR technical brief also highlights how international research on the topic has grown rapidly over the past decade, with significant development of new configurations, refrigerants, and hybrid systems. At the same time, energy performance is also improving: many HTHPs offer higher coefficients of performance than traditional fossil-fuel-based systems.

Economic competitiveness still depends on the cost of electricity and the local energy landscape, but the progressive growth of renewables could make these solutions increasingly advantageous in the long term.

HVAC, Industry, and Energy: Toward Integrated Thermal Systems

The growth of high-temperature heat pumps confirms an increasingly evident trend also for the HVAC sector: the progressive integration between energy recovery, electrification and industrial heat production .

Today, HTHPs are no longer seen simply as an alternative to traditional boilers, but as part of more advanced energy systems, in which heat recovery, thermal storage, and renewable generation work together to improve efficiency and sustainability.

For designers and operators in the energy sector, this means dealing with a new generation of industrial plants, where heat is no longer just an energy consumption to be managed, but a resource to be recovered and valorized within the production process.
