Project - IEA Annex 35 – Application of industrial heat pumps

IEA Annex 35 – Application of industrial heat pumps

Project start April 2010. Ended April 2014.

Background

Securing a reliable, economic and sustainable energy supply as well as environmental and climate protection are important global challenges of the 21st century. Renewable energy and improving energy efficiency are the most important steps to achieve these goals of energy policy.

While impressive efficiency gains have already been achieved in the past two decades, energy use and CO2 emissions in manufacturing industries could be reduced further, if best available technologies were to be applied worldwide.

Heat pumps have become increasingly important in the world as a technology to improve energy efficiency and reduce CO2 emissions. In particular industrial heat pumps (IHPs) offer various opportunities to all types of manufacturing processes and operations. IHPs are using waste process heat as the heat source, deliver heat at higher temperature for use in industrial processes, heating or preheating, or for space heating and cooling in industry. They can significantly reduce fossil fuel consumption and greenhouse gas emissions in drying, washing, evaporation and distillation processes in a variety of applications. Industries that can benefit from this technology include food and beverage processing, forest products, textiles, and chemicals.

The introduction of heat pumps with operating temperature below 100 °C is in many cases considered to be easy, however, higher temperature application still require additional R&D activities for the development of high temperature heat pumps, integration of heat pumps into industrial processes and development of high temperature, environmentally sound refrigerants.

In this context, the IEA HPP-IETS Annex 35/13 "Application of industrial Heat Pumps", a joint venture of the International Energy Agency (IEA) Implementing Agreements "Industrial Energy-Related Technologies and Systems" (IETS) and "Heat Pump Programme" (HPP) has been initiated in order to actively contribute to the reduction of energy consumption and emissions of greenhouse gases by the increased implementation of heat pumps in industry

Purpose

The objective of the Annex was to reduce the use of energy and emissions of greenhouse gas emissions by the increased application of heat pumps in industry, by

  • Generating information for policy makers
  • Developing information for key stake holders in industry and its supply and consulting chain and for policy makers
  • Getting insight in business decision processes
  • Increasing the knowledge and information about IHP’s, database and getting existing information available
  • Applying new technologies and identifying the needs for technological development
  • Creating a network of experts
  • Finding synergy with renewable energy production to increase flexibility of the grid

Activites

The annex has been subdivided in the following tasks:

  • Task 1: Market overview, barriers for application
  • Task 2: Modeling calculation and economic models
  • Task 3: Technology
  • Task 4: Application and monitoring
  • Task 5: Communication.

Participants

The Annex 35/13 had 15 participating organisations from Austria, Canada, Denmark, France, Germany (Operating Agent) Japan, The Netherlands, South Korea and Sweden.
