This report deals with the SUSHEAT deliverable 2.1, which provides information and data related to the energy demand of the industrial sector for high-temperature applications, the temperature specifications for meeting industrial heat demand, the potential for implementing SUSHEAT technologies, focusing on applying the Stirling-based-cycle heat pump and SHIP systems specifically in food and dairy industries, as well as fish meal and oil processing plants. Heat demand data for 2017 is provided for every European Union (EU28) country and industrial sector. The data reveals that the industrial heat demand for 2017 totalled 1600 TWh, accounting for around 50% of the total energy demand in the industrial sector. In 2021, final energy consumption in the European Union (EU) rises to 39,351 PJ, a significant increase of 6.2% compared to the previous year. Heat demand in this deliverable has been classified into various temperature ranges, starting from very low (up to 60°C), then low to medium (60 to 150°C), followed by medium (150 to 400°C), and high (above 400°C). The Heat pump technology has the potential to convert a significant portion of the existing 175 TWh excess waste heat potential into industrial-process heat, covering an estimated demand of 47 TWh in the 100–200 °C output temperature range.
