Global Environmental Benefits of Industrial Heat Pumps

By upgrading heat at a lower temperature, industrial heat pumps use their high-energy efficiency to meet heating needs in industry, therefore helping to reduce the consumption of fossil fuels and the associated emissions of CO2 and other harmful gases such as SOx, NOx, methane and carbon monoxide.

This project tried to gain a better understanding of the global energy and environmental benefits of industrial heat pumps, to broaden the knowledge base and disseminate the information. By conducting the most comprehensive survey of industrial heat pumps to date, the IEA determined that over 4,600 industrial heat pumps are currently used in Canada, France, Japan, the Netherlands, Norway, Sweden, UK and USA.

In addition to determining current users, each participating country conducted a market assessment using the Industrial Heat Pump Screening Program. This was specifically developed to determine how industrial heat pumps could be used in different applications. Estimates were made on the potential for using industrial heat pumps in over 35 different processes in the year 2010. The study indicated that industrial heat pumps could reduce the energy consumption for industrial process heating by 1,300 to 3,100 PJ per year worldwide, or 2-5% of the global energy demand for process heat by the target year. The screening program was updated in 1997 and is available from the HPC.

Objectives

The objectives of the project were:

  • To heighten industry’s awareness of the large energy savings associated with industrial heat pumping
  • To broaden the information available to industry to help further development of industrial heat pumps
  • To estimate the market potential for various types of industrial heat pumps and illustrate opportunities for their use
  • To estimate the potential environmental benefits of Industrial Heat Pumps resulting from energy savings and emissions reductions
