Business Administration and Production Management
03.03.2022 State Secretary Dr. Dirk Günnewig hands over the funding decision for the project Operations Research (OR) for Sustainability: Energy, Mobility, Industry
In scientific discourse and in research-based teaching, overcoming the climate crisis and increasing sustainability are central topics that are addressed, for example, in the courses of industrial engineering, mechanical engineering, environmental engineering, sales engineering and product management, business administration and economics. For the evaluation and design of our energy, mobility and industrial systems, decision-oriented, methods (e.g. linear programming, multi-criteria decision support) are required, as provided in particular by Operations Research (OR). The aim of the project is the development, implementation and dissemination of a digital, model- and application-oriented teaching/learning offer in the subject area "Operations Research for Sustainability". Current problems and solutions from the research projects of the University of Duisburg-Essen (coordination), Ruhr-University Bochum (RUB) and RWTH Aachen on the design of sustainable energy and mobility systems as well as industrial value chains will be didactically prepared and made available on the state portal ORCA.nrw.

New Publication: Environmental impacts of carbon capture and utilization by mineral carbonation: A systematic literature review and meta life cycle assessment
Thonemann, Nils; Zacharopoulos, Leon; Fromme, Felix; Nühlen, Jochen
Mineral carbonation technologies are associated with the concept of Carbon (dioxide) capture, utilization, and storage and rely on the mineralization reaction, which can be observed in nature. In order to overcome the slow natural reaction rates, diverse pathways are studied to sequester carbon dioxide into mineral products. However, studies that perform a life cycle assessment (LCA) on mineral carbonation are poorly comparable due to differences in the assessment methodology. A two-step approach is applied to report on and overcome this issue. First, a qualitative analysis based on a systematic literature review of 29 relevant articles was conducted. Second, a meta analysis with harmonized methodological assumptions was applied to assess which of the proposed ex-situ carbonation routes in literature has the lowest environmental impacts (16 different impact categories assessed). The qualitative literature review demonstrates that the most critical difference of the published LCAs on mineral carbonation technologies is handling multifunctional processes, as this parameter influences the result of an LCA. Since none of the assessed studies evaluated the technology readiness level (TRL) of the investigated technology, a TRL estimation based on the studies' descriptive information, ranging from 2 to 6, was provided. This is reflected in the predominant usage of laboratory or simulated data as the primary data source. The main finding of the meta analysis in terms of global warming and the impact category minerals and metals is that direct aqueous carbonation, carbonation mixing, and carbonation curing show negative values in those impact categories despite the deployed scenario. Hence, these three mineral carbonation technologies seem to be most promising. However, it could be demonstrated that other impact categories show positive results. In the case of indirect aqueous carbonation, it depends on the substitution credit assumed whether this pathway acts as a climate mitigation pathway.

Life Cycle Assessment of Synthetic Natural Gas Production from Different CO Sources: A Cradle-to-Gate Study
Eleonora Bargiacchi, Nils Thonemann, Jutta Geldermann, Marco Antonelli und Umberto Desideri
Fuel production from hydrogen and carbon dioxide is considered an attractive solution as long-term storage of electric energy and as temporary storage of carbon dioxide. A large variety of CO2 sources are suitable for Carbon Capture Utilization (CCU), and the process energy intensity depends on the separation technology and, ultimately, on the CO2 concentration in the flue gas. Since the carbon capture process emits more CO2 than the expected demand for CO2 utilization, the most sustainable CO2 sources must be selected. This work aimed at modeling a Power-to-Gas (PtG) plant and assessing the most suitable carbon sources from a Life Cycle Assessment (LCA) perspective. The PtG plant was supplied by electricity from a 2030 scenario for Italian electricity generation. The plant impacts were assessed using data from the ecoinvent database version 3.5, for different CO2 sources (e.g., air, cement, iron, and steel plants). A detailed discussion on how to handle multi-functionality was also carried out. The results showed that capturing CO2 from hydrogen production plants and integrated pulp and paper mills led to the lowest impacts concerning all investigated indicators. The choice of how to handle multi-functional activities had a crucial impact on the assessment.

The VHB has more than 2,600 members. The goal of the VHB as the professional association of business administration professors in the German-speaking countires is the promotion and further development of business administration as a socially relevant, internationally connectable and forward-looking academic discipline. Prof. Geldermann is the deputy chairwoman of the board of directors and responsible for research and publications from January 2021 to December 2022. In addition, she is designated Chairperson of the VHB from 2023 - 2024. Prof. Geldermann is very pleased about the trust placed in her by her colleagues. This honorary position also contributes to the visibility of our university as well as to the reputation of business administration at our faculty in Duisburg.
With all our exams for the winter semester 2019/20 written and already corrected as planned and all outstanding project meetings and business trips completed, the Chair would like to minimize the further risks that could result from the Corona pandemic. In particular, we would not like to contribute to the spread of the virus ourselves.
After several states and federal states have stopped teaching at schools and universities, we will therefore refrain from personal meetings and unnecessary travel as far as possible until after the NRW Easter holidays.
The lectures of the professorship will start on April 8, 2020, and we are currently preparing the contents for the lectures digitally. We will provide you with further information on the use of Moodle etc. by April 06, 2020 at the latest.
On 21.4. we will announce dates for exam reviews, provided that it will be possible to plan the review in a resonable way.
We expect to receive regular mail. We can be reached by email at the usual times. We will make sure that mails to the address email@example.com are read and answered regularly.
We thank you for your understanding!

Improving planning by integrating spatial data into decision support systems.
Journal of Decision Systems (2019) [Paper]
For many decision problems, the spatial availability of inputs or the spatial distribution of customers are important decision parameters that should be considered as precisely as possible. One example of such a decision problem is the strategic planning of so-called biorefineries. Biorefineries generate a variety of products from biomass, and their overall economic performance strongly depends on the regional availability of the scattered biomass inputs. However, spatial data is often omitted from performance analyses. In this paper, we show how spatial data can indeed be integrated into a decision support system using pre-editing in Geographic Information Systems (GIS) and GIS-Application Programming Interfaces (APIs). Towards this end, we describe the integration of spatial data into the planning process for two different biorefinery concepts in two different regions.KEYWORDS: GIS, spatial data, strategic planning, biomass biorefinery

Combining scenario planning, energy system analysis, and multi-criteria analysis to develop and evaluate energy scenarios.
Journal of Cleaner Production (2019) [Paper]
The transition from the current electricity system to a renewable electricity supply poses immense economic, technological, and policy challenges. Energy system models represent the complexity of interactions in combined processes from extraction of primary energy to the use of the final energy to supply services and goods. While these models were originally focused on energy security and costs, climate change, as the most pressing environmental concern as well as sustainability in general require the consideration of a broader range of decision-relevant aspects. In this context, scenario planning and multi-criteria decision-making can complement energy system analysis in the development and evaluation of energy scenarios. Therefore, we propose a combination of these three methods and illustrate it in a case study that investigates the transition of the electricity sector in Lower Saxony, Germany, to energy from renewable sources. The results of our case study show that the integration of multi-criteria analysis allows for better Problem structuring by focusing on relevant alternatives, external uncertainties, and evaluation criteria. The integration of scenario planning allows for a systematic investigation of external uncertainties. Thereby, the fallacy of investigating particular assumptions for uncertain parameters, which are however not consistent with the assumptions in the scenario, can be avoided. Finally, combining the methods allows for a more balanced and objective evaluation of alternative energy systems in terms of multiple criteria, which can be used to inform discussions among stakeholders and may thus increase acceptance.
