"E-Mobility" – Workshop "How Efficient is Electro Mobility?"

How "green" is E-Mobility really?

The field of "e-mobility" is highly complex and highlights one of the greatest issues of the future. The field challenges many research disciplines, the political world and many economic sectors. In June 2015, at the invitation of the University of Oldenburg and the Hanse Wissenschaftskolleg, a high-quality, international panel of experts was assembled to discuss the status of development in this field and the current problems faced.

According to the Federal Motor Transport Authority of Germany, in the start of 2015 44.4 million passenger cars were registered, of which almost 19,000 were electric cars. The federal government aims to reach its goal of having one million electric cars on the country’s roads by the year 2020. "Given the manifold problems, this is a very ambitious goal, which cannot be achieved with introducing sales incentives only," asserts Alexandra Pehlken, head of the junior research group Cascade Use of the University of Oldenburg regarding the development plans of the nation. “There is also still a long way to go until the concept of E-Mobility really becomes a green solution.”

Article published by JADLeT

Matthias' article on A Game-Based Learning Course for Education on Remanufacturing Supply Chains was recently accepted for publication by JADLeT Journal of Advanced Distributed Learning Technology (available online). In this article, Matthias discusses the potential of a game-based course for teaching requirements specific to the management of remanufacturing supply chains (closed-loop supply chains). Matthias gained teaching experience in game-based learning courses at the University of Bremen (Germany) and at the University Arturo Prat (Iquique, Chile) between 2011 and 2014. He could build on this previous knowledge when researching remanufacturing supply chains. With this article Matthias addresses a gap between the already developed theoretical foundation of closed-loop supply chains and its limited implementation in education and practice.

Participation in 7th ITEE International Conference in Port Elizabeth (South Africa)

(As announced at 1st of June) Matthias went to ITEE in Port Elizabeth, South Africa, to present his joint paper with Alexandra on Support for improved scrap tire reuse and recycling decisions during the 7th ITEE International Conference (July 14-16th, 2015). He took advantage of being in Port Elizabeth to meet with Cainos Mukandatsama, a PhD candidate from Nelson Mandela Metropolitan University (NMMU), who attended our Summer School at HWK earlier this year.

Furthermore, Matthias went to visit VW South Africa and Lumotech Ltd. and he met some industry representatives during the conference.

Discussing the future of E-Mobility

Challenging many academic disciplines, the highly complex issue E-Mobility is at the focus of a number of research groups at the University of Oldenburg, which foster an international dia-logue. For this reason, the research group Cascade Use was involved in organising the international summer school and conference "How efficient is electro mobility" that took place at the Hanse Wissenschaftskolleg in June 2015.

Whether the focus lies on battery, fuel cell and recycling technologies, energy efficiency, electricity grids and renewable energies or material cycles – research in a multitude of subjects relevant for E-Mobility is long-established at the University of Oldenburg, with the energy research network ENERiO, the research group Cascade Use and the affiliated institutes Offis and Next Energy being especially active in this area. Following their invitation, 50 researchers from all over the world convened at the Hanse Wissenschaftskolleg in Delmenhorst for three days in order to discuss the future of E-Mobility. This interdisciplinary workshop was sponsored by the programme International Promovieren in Deutschland – for all (IPID4all) of the German Academic Exchange Service (DAAD) and by the Stiftung Innovationspool of the Hanse Wissenschaftskolleg.

One of the conference’s key subjects was the topic of energy. Sustainable E-Mobility goes beyond just using renewable energies, the participants agreed, and requires smart grids. Demand-Side-Management, i.e. managing the demand of grid-connected services, remains an important field for research.

When considering the entire product life cycle, material flows, recycling and resource efficiency move increasingly into focus. "We urgently need new concepts and technologies", says Pehlken, whose research group deals with the utilisation of resources. "As it remains uncertain which type of battery will prevail in the future, the recycling industry is still hesitating", she explains. For example, the recycling of lithium-ion batteries has not been realised at an industrial scale yet and so far, initial solutions for automated disassembly only exist in laboratories.

Apart from batteries, fuel cell technology remains an important option for E-Mobility. This was demonstrated by contributions from Canada, one of the leading countries in fuel cell research. According to these experts, new recycling technologies – aimed at recovering the platinum contained in fuel cells, amongst other materials – are a prerequisite for the commercialisation of fuel cell vehicles. Further promising research on alternative materials for proton exchange membrane (PEM) fuel cells, which may significantly increase their power range, is conducted at the University of Oldenburg.

E-Mobility is also strongly promoted in China, where the focus lies on so-called New Energy Vehi-cles. These are hybrid vehicles that can be charged over the electricity grid. Since 2014, their share has increased drastically and today, one in 300 vehicles in China is a New Energy Vehicle. For com-parison: In Germany only every 412. vehicle was a hybrid and only every 2343. vehicle a full electric one in early 2015.

The conference was accompanied by a summer school attended by 25 PhD candidates from all over the world. As part of the summer school, the group also visited the Mercedes factory in Bremen and was given an introduction to the integration of electric vehicles in the city of Bremen by Veniox GmbH.

Cascade Use collaborates with German-Chilean Project for Sustainable Raw Material Supply

Matthias Kalverkamp, researcher from the research group Cascade Use participated in a scientific exchange which took place in April 2015 as part of a BMBF-funded WTZ project for Green Supply Chains in raw material extraction. Since 2013, the BIBA – Bremer Institut für Produktion und Logistik GmBH and the University Arturo Prat are working jointly in this project. Thanks to an invitation from BIBA, Matthias joined the BIBA-scientist Thorsten Wuest on a visit to Iquique in the north of Chile. The purpose of their visit was to establish further contacts with scientist and companies in that region. Their joint research aims at a closer examination of carbon footprints in supply chain and logistics mining processes. In the long run they want to promote that carbon foot printing is considered in decision making in such processes in mining. Findings from this work are also used to assess raw material flows in the context of the research group Cascade Use.

In addition, the researchers initiated a knowledge exchange between the involved institutions regarding the extended utilization of resources. They conducted a lecture on optimal circular resource flows in industrial and commercial environments. Besides, they discussed potential future fields of cooperation. For the research group Cascade Use and in particular for Matthias it is interesting to further investigate the free trade zone of Iquique (ZOFRI) and its effects on the used cars and end-of-life vehicle (ELV) market.
