HighEFF short course on Industrial energy recovery

A one-day course entitled “Industrial Energy Recovery” was held 19 March at the Scandic Bakklandet Hotel. A total of 28 participants were in attendance: 4 from industry, 7 from SINTEF Energy Research, 7 from NTNU (professors, postdocs and PhDs) and 10 Master's students. The core topic of the course was Process Integration with focus on analysis, design and optimisation of systems for Heat Recovery and Work and Heat Integration. Both thermodynamics-based methods (Pinch Analysis) and optimisation-based methods (Mathematical Programming) were described. There was also a brief introduction of the Exergy concept and how Exergy (considering both the first and second law of thermodynamics) can be used as a performance indicator for energy use in industry.

In addition to lectures based on 108 slides, ample time was dedicated to questions, answers and discussions. The course was given by Truls Gundersen, Professor Emeritus at the Energy and Process Engineering department, NTNU.

Choosing eco-friendly refrigerants for appliances

Some refrigerants are better for the environment than others, but making the right choice is easier said than done for the average consumer. We took a look at the available options to try and simplify things a bit.

HighEFF at the TMS Conference
in Orlando, USA, 3-8 March 2024

The annual TMS (The Minerals, Metals and Materials Society) conference brings together over 4000 engineers, scientists, business leaders and other professionals in minerals, metals and materials technology. The event sets the stage for a comprehensive, interdisciplinary exchange of technical knowledge.

HighEFF's Samuel Senanu, Egil Skybakmoen and Asbjørn Solheim contributed to the conference with the publication: "Sustainability of Different Aluminium Production Technologies". The publication, presented by Samuel, presented various aluminium production technologies evaluated at the HighEFF research Centre over its eight years of operation. Technologies discussed in the publication include inert anode technology, the chloride process, and improved Hall-Héroult technology.

Other publications that were presented and are relevant to the aluminium industry were "Limits for the Current Efficiency in Aluminium Electrolysis Cells" and "Aluminium Carbide and Carbon Dust in Aluminium Electrolysis Cells – A Conceptual Model for Loss in Current Efficiency", by Asbjørn Solheim, and "Online Monitoring of Metal Oxides in Molten Fluoride Electrolytes", co-authored by Samuel Senanu.

Additionally, REEL Norway's Håvard Olsen presented results from the HighEFF spin-off project Agate: "Preliminary testing and simulations of pot integrated Abart (PIA) at Alcoa Mosjøen". The publication is a collaboration between SINTEF, Alcoa Norway and REEL Norway.

The on-site turnout at the Aluminium reduction session was very good (60-80 participants throughout), with representatives from several global aluminium companies and international research institutes and universities.

HighEFF's participating scientists were met with many questions about the work done within the Centre, and generally in Norway regarding the green transition, renewable energy and other relevant topics.
