“ELMAR” project: The ISEA is part of it!

September 30th, 2022 | by

The objective of the ELMAR project is to integrate the use of electric heavy mining machinery in the domestic extractive industry and demonstrate its utility.

A secure supply of mineral raw materials is essential for the competitiveness and prosperity of Germany and Europe. At the same time, raw material extraction results in substantial carbon dioxide emissions and therefore needs to become more sustainable in order to help achieve climate targets and to remain competitive. This includes, in particular, the decarbonization of operations that extract raw material. In Germany, this affects around 1,600 companies with around 2,700 plants and 23,500 employees in gravel, sand, and natural stone production alone.

Up to now, a significant proportion of the energy used in the extraction of raw materials at these plants has been used for internal transport. And most of this energy is being consumed by mobile diesel-powered (heavy-duty) vehicles. Conversion to (battery) electric operation is therefore a key lever for reducing emissions in this sector. This applies to the retrofitting of existing companies as well as to future projects.

 

Decarbonization of Domestic Raw Material Extraction – A Holistic Approach

In the newly launched ELMAR project, a consortium of research and industry partners is investigating how the decarbonization of the raw materials sector can be achieved and implemented in a holistic approach. The project involves the deployment of autonomous electric heavy-duty electric mine transport systems, the adaptation of the infrastructure this requires, and the redesign of operational processes. In addition, the project seeks to optimize the matching of energy demand and energy supply with the help of a connected, model-based and intelligent operational management.

ELMAR lays an important foundation for the integration of electric automated mobile heavy-duty transport machines in raw material extraction,” says Dr. Tobias Hartmann of the Institute for Advanced Mining Technologies at RWTH Aachen University. “Maintaining process reliability in extraction while ensuring security of electrical supply, as well as coupling it to renewable energy sources, we want to demonstrate in representative application scenarios that electrical transport is possible in domestic resource extraction. The holistic approach taking production, energy demand and energy supply aspects int account makes it possible to optimize existing and upcoming operating concepts.”

The consortium consists of two RWTH institutes, the Institute for Advanced Mining Technologies (AMT) and the Institute for Power Electronics and Electrical Drives (ISEA), and industry partners. Volvo Group Trucks Central Europe GmbH, Volvo Construction Equipment Germany GmbH, and Volvo Autonomous Solutions AB (commissioned by VCE Germany GmbH), are participating as construction equipment and transport vehicle manufacturers and automation providers. Other partners include mine operators Mineral Baustoffe GmbH (part of the STRABAG Group), Knauf Gips KG, and Nivelsteiner Sandwerke & Sandsteinbrüche GmbH; AI and cloud-based software providers PSI Fuzzy Logik & Neuro Systeme GmbH and PSI Software AG; and TITUS Research GmbH as a developer of autonomous monitoring systems.

The ELMAR project is scheduled to run until the end of July 2025 and receives around 6 million euros from the German Federal Ministry of Economics and Climate Protection (BMKW) as part of the “Research and Development in the Field of Electromobility” funding initiative.The total project volume is around 11 million euros.

Dr. Weihan Li has been awarded the second German Study Prize of the Körber Foundation for his dissertation.

Every year, the foundation awards the German Study Award to the best doctoral students from all disciplines. The main focus here is on the social significance of the research. We congratulate Dr. Weihan Li from the Institute for Power Electronics and Electrical Drives for his outstanding achievement.

Abstract:
Machine learning for efficient battery use in mobility and energy supply for sustainable climate protection
In the fight against climate change, batteries play a crucial role as a flexible energy storage system for renewable energies. However, battery ageing during use is proving to be the limiting factor for an efficient and reliable future energy system. In this work, machine learning enables online ageing diagnosis, prediction of future ageing progression and optimisation of operation strategy, which not only increases battery performance and lifetime, but also reduces unexpected failures and contributes to more transparency about battery health. The methodology developed improves battery use in mobile and stationary applications, enabling safer and longer-lasting operation, which saves costs in the long term, conserves resources and is socially feasible. This work thus provides an essential building block for the broad acceptance and implementation of climate-friendly mobility and energy supply on the way to a climate-neutral energy system.

We would also like to congratulate Dr. Lars Nolting from the Chair of Energy System Economics at RWTH Aachen University on winning the first prize, as well as all the other prize winners:
Dr. Manuel Häußler from the University of Konstanz, Dr. Kim Teppe from the University of Hamburg, Dr. Julia Böcker from the University of Lüneburg, Dr. Mareike Trauernicht from the Free University of Berlin and Dr. Felix Lansing from the Technical University of Dresden.

Healing Achilles heel of two-dimensional transistors

Stability – in the sense of stable operation thorough lifetime – is one of the key characteristics that an electronic device need to present to be suitable for applications. And it is the Achilles heel of transistors based on two-dimensional materials, which typically show much worse stability than devices based on silicon. A team of researchers from TU Wien, AMO GmbH, RWTH Aachen University and Wuppertal University has now demonstrated a novel engineering approach to enhance the electrical stability of two-dimensional transistors by carefully tuning the Fermi energy. The results have been reported in Nature Electronics.

Today, there is little doubt that devices based on graphene and other two-dimensional (2D) materials can exceed the state of the art for certain applications, thanks to their intrinsic properties. Two-dimensional materials are also seen as some of the most promising candidates for realizing ultimately scaled transistors at the end of the roadmap of silicon technology.  However, devices based on 2D materials often show poor electrical stability, meaning that their behavior changes depending on their operation history.

“Component reliability is one aspect that is often neglected in research. This is precisely where we have been working for several years, because it is of central importance for applications.” explains Professor Max Lemme, scientific director of AMO GmbH and Head of the Chair of Electronic Devices at RWTH. The instability is not only caused by 2D materials themselves, but mostly by charges trapped into the oxide-insulator used to fabricate the transistors. “Ideally, one would like to use a different insulator with fewer charge traps,” says Lemme, “but there are no scalable solutions for this yet. In our work, we have shown instead that it is possible to use a standard insulator such as aluminum oxide and to significantly suppress the adverse effects of the charge traps in the oxide, by adjusting the charge carrier density in the 2D material.”

The work combines a thorough theoretical analysis of the novel approach – dubbed by the authors ‘stability-based design’ – and a proof of principle demonstration of the concept, performed by measuring different types of graphene-based FETs. The key idea of the approach is to try to engineer the combination 2D-material/insulator in such a way that the energy of the charge traps in the insulator is as different as possible from the one of the charge carriers in the 2D material. Lemme explains: “Graphene based FETs were the ideal test bed for our approach, as it is relatively easy to tune the energy of charge carriers in graphene. The approach, however, is applicable to all FETs based on 2D semiconductors”.  These results represent a major step forward towards stable and reliable 2D materials transistors to be integrated in semiconductor technology.
