This report addresses the cost-effectiveness of process heat decarbonisation and power-to-heat options in the manufacturing industry with process temperatures of up to 120 °C. Options include high temperature heat pumps (HTHP), renewable or low-carbon fuels or combined heat and power plants. Previous studies have identified a large potential to adopt such options in Switzerland. However, high technology, energy and integration costs have been obstacles to integrate these technologies in existing processes. In addition, energy price developments have been very dynamic. Hence, we here provide an up-to-date assessment
