Symposium on: Streamlining the optimisation of Sustainable Thermal Energy systems and Prototype technologies in process industries 

The European process industries play a vital role in achieving climate neutrality by 2050, currently responsible for 20% of greenhouse gas emissions and 25% of final energy consumption in Europe. A significant portion (66%) of industrial energy use is dedicated to process heating. While technologies like heating electrification can support decarbonisation, challenges such as high upfront costs, low digitalisation, and the need for further R&D on heat pumps remain. Sustainable heating technologies aim to improve energy management at the plant level through peak reduction and load shifting.

 StreamSTEP: Streamlining the adoption of advanced solutions, comprising both technologies and practices, for sustainable heating energy in energy-intensive industries

The StreamStep project aims to improve heating energy management in industrial processes. The

project will deploy five innovative heat exchanger prototypes for waste heat across temperatures from 135°C to over 1400°C. High-temperature heat pumps will enhance heat recovery, achieving outlet temperatures of 150°C and 215°C, with improved performance through ejector technology. Advanced manufacturing techniques and novel material alloys will enable these innovations. The system will be demonstrated across five sectors, copper, ceramics, silicon, plastics and oil & gas, with significant impacts on waste heat recovery, productivity, and energy flexibility.

Researcher, Sarina Bao is the Coordinator,  Senior Researcher Eivind Johannes Øvrelid  is the Scientific and Technical Director, and Prof. Hussam Jouhara is the Demonstration Implementor of the StreamSTEP project.

StreamSTEP Solutions

Advanced Heat Exchanger (AHX)

5 advanced HX prototypes will be delivered, tailored to challenging applications in process industries while employing advanced manufacturing technologies to address challenging streams (e.g., corrosion, erosion, non-steady waste heat streams, radiative sources), cost-efficiency, heat recovery rate between 50-90%, from gaseous and solid media, with dynamic operation.

High Temperature Heat Pump (HTHP)

High temperature heat pumps (HTHPs) are introduced to address challenges for sustainable heating energy use, with outlet temperatures in the 150-215 °C range and revise the role of ejector components to further boost HTHP coefficient of performance – COP.

Process Industry Digitalisation 

Process data collection and management platform will be consolidated, providing the digital infrastructure needed for the planning and management of process lifecycle, supported by the integration of sensor configurations, enabling real-time and predictive monitoring. 

Improved heat performance 

Combine various additive manufacturing techniques with digital advancements to improve efficiency, sustainability, and design flexibility while reducing material use, cycle time, and costs enabling concept improving heat performance.

Smart energy Planning and Management 

Process hybrid Digital Twin (HDT) framework will be consolidated to enhance the design and management of heat recovery and reuse processes, utilising virtual models to simulate and optimize real-world systems.

Expected Impact

StreamSTEP will find ways to adopt advanced solutions, comprising both technologies and practices, for sustainable heating energy in Energy Intensive Industries leading to the following impacts:

  1. Consolidate a process data collection and management platform, providing the digital infrastructure needed for the planning and management of process lifecycle.
  2. Consolidate a process hybrid Digital Twin (HDT) framework to enhance the design and management of heat recovery and reuse processes.
  3. Reduce 25% environmental footprint of heat exchanger and heat pipe components manufacturing.
  4. Deliver 5 advanced HX prototypes – DC1 Copper, DC2 Ceramic, DC3 Silicon, DC4 Plastic, DC5 Oil and gas.
