High-temperature heat pumps in climate pathways for selected industry sectors in Switzerland MICHEL D. OBRIST A, 1 RAMACHANDRAN KANNAN, 1 RUSSELL MCKENNA, 4,5 THOMAS J. SCHMIDT B,C. 2,3 & TOM KOBER. 1 To reach the goals of long-term energy and climate policy, the contribution of the industrial sector is important. Upgrading low temperature industrial waste heat using electric high-temperature heat pumps (HTHPs) can improve the overall energy-efficiency and mitigate CO2 emissions by replacing fossil fuels. The pulp and paper and the food and beverage industries use significant quantities of heat up to 200°C and therefore have a high potential for the application of HTHPs. In order to assess the role of HTHPs, a techno- economic bottom-up cost optimization model is developed building on the Swiss TIMES Energy system Model (STEM). We present an advanced modeling framework including energy and material flows, with a high temporal resolution and a segregation of the temperature level of the process heat. The results show that HTHPs are cost-effective up to a temperature of 150°C. Switzerland has the economic potential to deploy of about 100 MW th in the pulp and paper industry and 900 MW th in the food and beverage industry by 2050. Incentivizing the exploitation of this significant potential will require very high CO2 prices of several hundred €/tCO2 or additional policies to overcome investment barriers by supporting investment and flexible system-serving operation of heat pumps.

The Paper Industry Technical Association (PITA) is an independent organisation which operates for the general benefit of its members – both individual and corporate – dedicated to promoting and improving the technical and scientific knowledge of those working in the UK pulp and paper industry. Formed in 1960, it serves the Industry, both manufacturers and suppliers, by providing a forum for members to meet and network; it organises visits, conferences and training seminars that cover all aspects of papermaking science. It also publishes the prestigious journal Paper Technology International ® and the PITA Annual Review , both sent free to members, and a range of other technical publications which include conference proceedings and the acclaimed Essential Guide to Aqueous Coating .
