R&D ON INDUSTRIAL HEAT PUMPS


More than 80% of the total energy use in industry consists of the need of heat in the form of steam at different pressure levels and for firing furnaces. The total industrial heat use together with exothermic heat from chemical reactions is eventually released to the
ambient atmosphere through cooling water, cooling towers, flue gasses, and other heat losses. This heat loss is called ‘Industrial waste heat’. A first, most logical, solution to this waste heat problem is to reuse the heat within the same process through process integration or at the same site. If this is not possible, problems with temperature level, timing or location
can be solved by heat pumping, heat storage or heat distribution. This paper focuses on heat pumping. European R&D and the goals set are defined by the European Technology Platform on Renewable Heating and Cooling (RHC-Platform) in their recent Strategic
Research and Innovation Agenda for Renewable Heating and Cooling. Industrial heat pumps are an important part in that strategy. The report is presented to the European Commission
as advice on which technology to support.

In the Netherlands an extensive program under ISPT focuses on heat pumping technologies tackling many of the topics raised under RCH. A general description of research and
development projects is given where it should be noted that for confidentiality reasons, exact details of the process and the control and design alternatives for these projects are not provided and only described in general terms.
