Executive Summary 1-8 Introduction 1 Introduction 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 im- prove energy efficiency and reduce CO2 emissions. In particular industrial heat pumps (IHPs) offer various opportunities to all types of manufacturing processes and opera- tions. IHPs are using waste process heat as the heat source, deliver heat at higher tem- perature for use in industrial processes, heating or preheating, or for space heating and cooling in industry. They can significantly reduce fossil fuel consumption and green- house gas emissions in drying, washing, evaporation and distillation processes in a varie- ty of applications. Industries that can benefit from this technology include food and bev- erage 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 addi- tional R&D activities for the development of high temperature heat pumps, integration of heat pumps into industrial processes and development of high temperature, envi- ronmentally 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 "Indus- trial Energy-Related Technologies and Systems" (IETS) and "Heat Pump Programme" (HPP) has been initiated in order to actively contribute to the reduction of energy con- sumption and emissions of greenhouse gases by the increased implementation of heat pumps in industry The Annex 35/13 started on 01. April 2010 and expired on 30. April 2014 with 15 partici- pating organisations from Austria, Canada, Denmark, France, Germany (Operating Agent) Japan, The Netherlands, South Korea and Sweden. The Annex comprised an overview in the participating countries of the industrial energy situation and use, the state of the art and R&D projects in heat pumping and process technologies and its applications, as well as analysing business cases on the decision- making process in existing and new applications and in the wider application of industri- al heat pumping technologies. The annex has been subdivided in the following tasks:  Task 1:  Task 2:  Task 3:  Task 4:  Task 5: Market overview, barriers for application Modeling calculation and economic models Technology Application and monitoring Communication.
