On 17 April, Professor Antonello Monti of RWTH Aachen University will speak at the scientific meeting of the engineering and economics class of the “Nordrhein-Westfälische Akademie der Wissenschaften und der Künste” about the development goals of his discipline in terms of solving major societal challenges.

Against the background of the international situation, the energy transition process is more important than ever.The necessary technological transformation of the energy system must be approached from two angles: On the one hand, a new major player in energy supply has emerged: renewable energy. On the other hand, there are new consumers such as electromobility and heat pumps. Digitalisation is proving to be a key enabler in this process. You could even say that digitalisation is not an option, but a necessity. The power system is consequently becoming a large, programmable cyber physical infrastructure with a high level of complexity. In his presentation “The Digitalisation of the Energy Systems: from the electrons to the cloud”, Professor Monti addresses this complexity by analysing the solutions currently being developed for the different levels of the infrastructure.

” Rethinking the whole architecture means reconsider the basic principles of operation of the new power system but also the corresponding IT systems”,
announced Professor Monti, Director of the Institute for Automation of Complex Power Systems (ACS).

So what does it mean to run a digital grid? And will we be able to build a digital grid that is as reliable as the current infrastructure?

The solutions he proposes in his presentation are the result of concrete experience from large European research projects. Professor Monti leads a research group with about 50 full time scientists working intensively on the the border between energy and information and communication technologies. He is responsible for coordinating some of the most relevant European projects in this field, such as OneNet, TwinEU und int:net. His research work has received several awards, including the prestigious “IEEE Field Medal Award for Innovation in Public Infrastructure” and the “NRW Innovation Award”.

In another presentation – “Sustainable metals: contributions from basic research” – Professor Dierk Raabe from the Max Planck Institute for Sustainable Materials will address the question of whether we can succeed in decarbonising a key industry with “green steel”.

This admission is considered one of the highest academic honours that can be achieved in North Rhine-Westphalia (NRW). Congratulations!

In addition to Dr Jan Moritz Joseph, Junior Professor Lisa Spantig, Dr Maike Dohrn and Dr Julia Exarchos – all from RWTH Aachen University – were also accepted into the Young Academy of the North Rhine-Westphalian Academy of Sciences, Humanities and the Arts. The Academy has accepted a total of 19 new scholarship holders into its Young Academy. The RWTH has the most new members. Admission to the “Junges Kolleg” is one of the most important honours for young academics in North Rhine-Westphalia. They receive an annual grant of 10,000 euros and take part in academy events.

Dr Jan Moritz Joseph from the Institute for Communication Technologies and Embedded Systems (ICE) at RWTH Aachen University is researching energy-efficient methods for the design and use of AI in embedded systems. The focus is on neuromorphic hardware. Traditionally, AI is executed on systems in which computing and memory units are separate, which limits performance. Neuromorphic systems combine both units in a new component and are therefore more energy-efficient. Dr Jan Moritz Joseph and his team are designing an integrated system in which hardware and software are developed together. He and his team received the RWTH’s Innovation Award 2022 for the best transfer project for their hardware and software development systems. He studied computer science and medical technology and received his doctorate in electrical engineering and information technology in 2019.

The academy has been supporting young talent in NRW with the “Junges Kolleg” since 2006 and now has around 170 active, associated and former scholarship holders. In addition to a doctorate, membership requires outstanding academic achievements at a university or research institution in North Rhine-Westphalia. Members must not be older than 36 at the time of admission. RWTH Aachen University currently has seven researchers in the “Junges Kolleg”.

We at the Faculty of Electrical Engineering and Information Technology would like to congratulate Dr Jan Moritz Joseph on joining the Academy.

Innovative technologies and sustainable solutions in focus: RWTH start-ups make their mark in the fight against climate change.

The NRW 2023 Innovation Award has put the spotlight on two outstanding RWTH spin-offs: “Accure” and “Cylib”. These two start-ups not only have their roots at RWTH Aachen University, but also share a common mission – to fight rising temperatures and the associated challenges of climate change.

“Accure” was founded in 2020 by Dr. Kai-Philipp Kairies, Dr. Georg Angenendt and Dr. Johannes Palmerist and emerged from the Chair of Electrochemical Energy Conversion and Storage Systems Technology headed by Professor Dirk Uwe Sauer. Dirk Uwe Sauer and co-founder Kai-Philipp Kairies accepted the NRW 2023 Innovation Award in the “innovation2business” category in Düsseldorf. This award recognizes individuals who have developed successful business models from outstanding ideas.
The start-up specializes in monitoring the performance, safety and lifetime of batteries based on big data and the use of artificial intelligence (AI). Such an innovative approach is crucial for the introduction of sustainable energy storage solutions. Dirk Uwe Sauer emphasizes the need to transfer scientific findings to the business world in order to have a positive impact on society. This is exactly what “Accure” has successfully achieved.

“This honor means a lot to us,” says Sauer, “because we are standing up for changing things with our research.”

The award in the “innovation2business” category comes with prize money of 50,000 euros, which will be earmarked for further research purposes.

The evening was even more exciting than for “Accure” for Lilian Schwich, one of the three founders of “Cylib”. While “Accure” had already been determined as the award winner before the event, Lilian Schwich had to compete against two other nominees in the “innovation4transformation” category on Monday evening.
The start-up, which she founded together with her husband Dr. Gideon Schwich and Paul Sabarny, has spent years developing a process at RWTH Aachen University to recycle all the components of a lithium-ion battery. The goal is to recover all components and thus close the gap in the circular economy. This approach is not only more effective, but also more environmentally friendly compared to the current state of the art.

“The award is also a recognition for the long hard time of research,” said Lilian Schwich, “with research we spent many hours, days, weeks, weekends.”

The audience award “innovation4transformation” is given to personalities whose innovative products, solutions or business models contribute in an outstanding way to solving transformation challenges. This category is endowed with 25,000 euros and recognizes the contribution of “Cylib” to the circular economy and environmental protection.

Both awards underscore the important role of RWTH spin-offs in developing innovative solutions to the pressing challenges of the 21st century, particularly in the fight against climate change. With their groundbreaking technologies and sustainable approaches, they are pioneers on the path to a more environmentally friendly and sustainable society.

Other highlights included three keynote presentations from renowned individuals with expertise:

For Team Viewer, Dr. Hendrik Witt presented real-life use cases for augmented reality solutions for process optimization in the working world and explained the extent to which wearables and sensors are driving the industrial metaverse. The goal, he said, is digitization far from desks, for example in logistics, manufacturing or field service. Team Viewer sees the metaverse as an interface between the real world, the Internet and technology. Its AR platform Frontline offers augemnted reality, mixed reality and artificial intelligence on smart glasses, smartphones, tablets and other wearables. Empowered so-called frontline workers through this could usher in the next industrial revolution.

Professor Nilesh Madhu of Ghent University vividly explored the evolution of communication technology in his talk; from the use of tedious, hand-made, stochastic models to a plethora of impressive state-of-the-art data-driven approaches. His remarks also allowed a glimpse into the future and opened the discussion on whether the knowledge and experiences of the past are suitable to pave the way there.

Focusing on practical experience and the application of research results, Professor Frank Kurth from the Frauenhofer Institute for Communication, Information Processing and Ergonomics presented concrete safety application scenarios that use various approaches, including Deep Learning, for information extraction. Especially with respect to voice communication, the extraction of information from sensor signals is a significant aspect of safety-critical applications. This requires reliable methods, while complying with applicable law. The challenge here is often the poor quality of audio signals combined with the need to process large amounts of data in real time.

In addition to the exciting scientific content shared at the conference, a rich cultural offer was also opened to the participants. The city of Charlemagne showed its best side during the various guided tours and allows many insights into its historical heritage.

The conference was organized by the Informationstechnische Gesellschaft (ITG) in VDE, in cooperation with the Technical Committee Speech Communication AT3, as well as the Technical Program Committee and the Institute for Communication Systems at RWTH Aachen University.
