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.

The project for CO2-neutral energy supply in Herzogenrath, the first city in NRW to strive for this goal, is accompanied by a consortium of four chairs and institutes, including the Chair of Electrochemical Energy Conversion and Storage Systems Technology.

Herzogenrath wants to achieve CO2-neutral energy supply by 2030. A consortium of Siemens Energy, RWTH Aachen University, Aachen University of Applied Sciences and the Niederrhein University of Applied Sciences is conducting research on the project “Energy Park Herzogenrath Research & Development”, which is funded by the Federal Ministry of Economics and Climate Protection with 2.7 million euros. The project is also closely interlinked with other ongoing research and funding projects: at the local flat glass manufacturer Saint Gobain, CO2-free production is being researched, in which the Chair of Electrochemical Energy Conversion and Storage Systems Technology at the E.ON Energy Research Center (ERC) of RWTH Aachen University is involved. The aim is to recycle the heat generated during glass production in Herzogenrath and Kerkrade in the Netherlands as green heating energy.

The project uses a digital twin that virtually maps and simulates the energy supply. In this way, different scenarios can be tested and optimised. The project looks at generation, consumption and marketing options across sectors. RWTH is receiving around 918,000 euros in funding for this.

Climate protection through electrical engineering – Professor Dirk Uwe Sauer’s lecture at the Children’s University

Whether drought, floods or forest fires – the consequences of global warming are dramatic for nature and people. The countries of the global south are being hit particularly hard, but the effects are also being felt here. We experienced this at the latest with the devastating floods in July 2021. That is why we urgently need to address the issue of climate change. 

This is also what Dirk Uwe Sauer, Professor of Electrochemical Energy Conversion and Storage Systems Technology at RWTH Aachen University, is doing. He has been researching new energy systems for over 30 years and advises politicians on the energy transition.

„We see in all places that climate change is happening – with many negative consequences. And we urgently need a radical change in the way we have supplied ourselves with energy so far.“

This does not only affect us adults, but especially the children and young people of today. They will have to live with the limitations that climate change will bring. “I don’t think we should underestimate what children know and what they are capable of,” says Professor Sauer.

It is not too late to make a difference

In his lecture, the physicist not only explained the dangers of climate change, but also made the necessary changes understandable. He used various materials such as videos, slides and interactive presentations to show the physical basics and the possibilities through timely action: “I also want to spread optimism and show that things can also get better than they currently are. Because if we still grab the wheel in time, then we still have the possibility to avoid worse things.” For this to happen, however, society must overcome its fear of new technologies. The professor said that there is too much talk about the risks instead of seeing the opportunities. “And we simply can’t afford that now either.” A ruling by the Federal Constitutional Court in 2021 has obliged politicians, and thus the population, to act more quickly. The slower progress is made, the more the living conditions of the next generations are restricted. That is why the previous federal government tightened the climate protection targets and the Climate Protection Act. “We have the opportunity to achieve these goals. We have the necessary technologies to supply all eight billion people in the world properly with renewable energy,” Sauer said.

Climate change is an important issue that concerns us all. But what does it actually mean and how can we work against it? Professor Sauer explained this to the children in his lecture at the Children’s University on 16 June 2023. He showed them how the earth is warming up and what consequences this has for nature and people. He also presented solutions on how we can protect the climate with renewable energies and new technologies. For example, with solar cells that generate electricity from sunlight, or with electric cars that emit no exhaust gases. Professor Sauer showed the children not only the problems of climate change, but also the opportunities that arise from it. He showed them that we can not only influence the climate with our energy supply, but also promote biodiversity.

„I would like to show the children that, for example, large photovoltaic systems on open fields not only generate electricity, but also create space for extensive agriculture, for insects that can live and flourish in these areas again.“

Climate change is a major challenge that we can only overcome together. For this, we need an awareness of the connections between energy and the environment that starts with children. Another goal of the Children’s University event was to get the children excited about scientific topics. “Physics has the great advantage that it can illustrate things very vividly and also show connections,” said Sauer. Using simple means, Professor Sauer showed where research starts and what possibilities can arise through technical progress.
