Executive Summary 2-9 Market overview, barriers for applications 2 Market overview, barriers for applications The Task 1 Report summarized the present energy situation in general and the industrial energy use and related heat pump market subdivided into participating countries. Based upon these findings focus will be given to further work to meet the challenges for the wider application of industrial heat pumping technologies. Although heat pumps for the industrial use became available on the markets in the par- ticipating countries in recent years, just very few carried out applications can be found. To distinguish the reasons for this situation, application barriers were also a part of the survey in Task 1: Lack of knowledge: The integration of heat pumps into industrial processes requires knowledge of the capabilities of industrial heat pumps, as well as knowledge about the pro- cess itself. Only few installers and decision makers in the industry have this combined knowledge, which enables them to integrate a heat pump in the most suitable way. Low awareness of heat consumption in companies: In most companies knowledge about heating and cooling demands of their processes is quite rare. This requires expensive and time consuming measure- ments to find an integration opportunity for an industrial heat pump. Long payback periods: Compared to oil and gas burners, heat pumps have relatively high investment costs. At the same time companies expect very low payback periods of less than 2 or 3 years. Some companies were willing to accept payback periods up to 5 years, when it comes to investments into their energy infrastructure. To meet these expectations heat pumps need to have long running periods and good COPs to become economical feasible. High temperature application From the technical point of view one barrier can be identified regarding to the temperature limits of most commercially available heat pumping units. Many applications are limited to heat sink temperatures below 65°C the theoretical potential for the application range of IHP increases significantly by developing energy efficient heat pumps including refrigerants for heat sink temperatures up to and higher than 100°C. The barriers can be solved, as shown in the results of the Annex: short payback periods are possible (less than 2 years), high reduction of CO2-emissionen (in some cases more than 50 %), temperatures higher than 100°°C are possible, supply temperatures < 100 °C are standard.PDF Image | Industrial Heat Pumps
