How catalysts become more active

March 26th, 2021 | by

Researchers from Jülich, Aachen, Stanford, and Berkeley have studied the layer-by-layer structure of catalyst material. They have discovered that a surface layer as thin as a single atom can double the activity for the reaction of water splitting – without increasing the energy consumption. This also doubles the amount of hydrogen produced.
The scientists hope that this increased understanding will allow developing better catalysts in the future to produce green hydrogen more energy-efficiently, and thus more cost-effectively, than before. Hydrogen is called green when it is produced by the electrolysis of water in a climate-neutral way using electricity from renewable sources. Hydrogen is regarded as an essential building block of the energy transition, partly because it can store wind and solar energy in times of oversupply and release it again later.

Part of the research results came about at the Peter Gruenberg Institute, Electronic Materials Division, in the Electronic Oxide Cluster Laboratory of Professor Regina Dittmann.

5 Years Helmholtz Institut Münster “Center for Ageing, Reliability and Lifetime Prediction of Electrochemical and Power Electronic Systems” (CARL)

March 11th, 2021 | by

Powerful battery technology is a core element that benefits us in many everyday applications. From smartphones to wireless work devices and electric vehicles – batteries are shaping our lives to an ever-increasing degree.
Around 2012, the idea was born to combine the expertise of Forschungszentrum Jülich, RWTH Aachen University, and the University of Münster in battery research. Thus, 5 years ago now, the Helmholtz Institute Münster “Ionics in Energy Storage” was founded, which has now become a respected part of the battery research landscape and leads to the continuous development of research infrastructures at the different locations. In Aachen, this is reflected by the construction of the “Center for Ageing, Reliability and Lifetime Prediction for Electrochemical and Power Electronic Systems (CARL)”.

Hybrid Provision of Energy based on Reliabilty and Resiliancy via Integration of Dc Equipment

February 26th, 2021 | by

The project HYPERRIDE started on 1 October 2020. The four-year project contributes to the field implementation of DC and hybrid AC-DC grids. It will actively identify and provide solutions to overcome barriers to successful roll-out of new infrastructure concepts throughout Europe.

The Institute for Automation of Complex Power Systems (ACS) will concentrate its work on the development of automation services for the hybrid AC/DC grid. The focus here is on optimal power flow and fault management, as well as on the realization of a metering device specifically dedicated to DC technology: the DC Measurement Unit (DMU).

These solutions will be integrated into the open ICT platform, specifically tailored for integration with hybrid AC/DC distribution systems, and tested, among the others, in the demo site of the RWTH Aachen Campus Melaten.

SOGNO – Service Oriented Grid for the Network of the Future

December 2nd, 2020 | by
Serviceorientiertes Stromnetz für die Stromversorgung der Zukunft

Institute for Automation of Complex Power Systems

RWTH Aachen University recently had a major role in the EU project „Service Oriented Grid for the Network of the Future“ (SOGNO). RWTH was represented by the Institute of Automation of Complex Power Systems (ACS), the Institute of Theoretical Information Technology (TI), and the Chair of Management Accounting. Moreover, Prof. Monti and Dr. Marco Pau from the Institute of Automation of Complex Power Systems served as technical managers of the project, thus coordinating the technical activities within the consortium.

The project SOGNO aims at developing a new concept of distribution grid management, based on the use of 5G communication, advanced deep learning techniques, and cloud virtualization to provide the intelligence needed to control future smart grids as a service for distribution system operators.

Project InductInfra – Will Roads Be Able to Supply Cars With Energy in the Future?

December 1st, 2020 | by

Within the project “InductInfra – Inductive Dynamic Energy Supply of Vehicles via Road Traffic Infrastructure” the Institute of Electrical Machines under the direction of Professor Kay Hameyer and the Institute of Highway Engineering under the direction of Professor Markus Oeser cooperate in this field. The project is financed by the Federal Ministry of Transport and Digital Infrastructure within the framework of the “Road Innovation Program” with about 1.6 million Euros until October 2023.

Both institutes want to develop concepts and material systems for energy transmission between vehicle and road and to research integration into the infrastructure. The aim is for vehicles to draw the energy required for operation or rapid charging from an induction field while driving. Induction modules embedded in the road generate the energy required for this. The project aims to develop the induction modules, the necessary materials and the technologies for their permanent integration into the transport infrastructure. Furthermore, the potential, operational safety and economic efficiency of supplying the induction modules with renewable energy will be determined.

Currently, the electrification of individual and commercial transport is in focus. There are still many problems for long-distance traffic, such as the lack of range, battery size, battery weight and the incomplete charging infrastructure. One possible solution could be continuous charging or energy transfer between the vehicle and the road during the journey. Electric vehicles with a virtually unlimited range, moderate battery size and low battery weight would thus become possible.

In April this year, the second version of the “ERIGrid 2.0” project of the Institute for Automation of Complex Power Systems at the E.ON Research Center was launched.

Its full name is as complex as the four-year project as “ERIGrid 2.0” stands for “European Research Infrastructure supporting Smart Grid and Smart Energy Systems Research, Technology Development, Validation and Roll Out – Second Edition”.

Professor Antonello Monti’s team is working on the holistic and cyberphysics-based validation approach for intelligent energy networks in the electrical sector. ERIGrid 2.0 provides support and training at system level for industrial and academic research and technology development for energy systems.

100 million euros for battery research

July 22nd, 2020 | by

 

BMBF funds battery competence cluster under RWTH leadership

As part of the overarching concept “Battery Research Factory”, the Federal Ministry of Education and Research is funding four additional battery competence clusters with a total of 100 million euros.

Professor Dirk Uwe Sauer from the Institute for Power Electronics and Electrical Drives (ISEA) coordinates the cluster “Battery Usage Concepts” (Batt Usage), which is funded with around 20 million euros. The aim is to develop a profound understanding of battery conditions and behavior to decide when secondary use of battery storage is possible and for which applications it makes the most sense.

The “Intelligent Battery Cell Production” cluster (InZePro), which is being funded with around 30 million euros, aims to increase and enhance flexibility in the productivity of cell production. This is intended to be achieved through comprehensive optimization of the production system using Industry 4.0 solutions.

The aim of the “greenBatt” recycling/green battery cluster is to close material cycles in the battery business. This cluster is also funded with around 30 million euros.

The “Analytics/Quality Assurance” (AQua) cluster focuses on continuously improving the performance of batteries while at the same time ensuring a long service life and a high level of safety. This cluster will receive funding of around 20 million euros.

The new clusters deal with future topics in battery research, ranging from production and usage concepts to recycling and quality assurance. RWTH Aachen University is involved in three of the four new clusters.
