Techno-economic analysis of integrated water infrastructure projects 

Schär, Sebastian; Geldermann, Jutta

Infrastructure concepts for the water supply of Jordan and Palestine are to be planned across borders and include desalination plants, conveyance plants and pipe networks for the distribution of treated water in supply areas. In addition, hydropower plants can be included in such integrated water infrastructure projects. This paper presents a techno-economic analysis for a very early planning stage. 

01.08.2022 SALAM project completion

The Middle East is one of the driest areas in the world. The scarce freshwater resources cannot meet the growing demand and are heavily overused. Political tensions in the region make community-based water management difficult. To avoid a widening of the regional water crisis, the SALAM initiative is developing transboundary water transfer strategies with partners from Germany, Israel, Jordan and Palestine. 

SALAM is a continuation of work in the region that has been ongoing for more than 25 years. Close cooperation has developed in the water sector, bringing together partners in the Middle East to find a common solution to the water deficit. SALAM is supported by the Federal Ministry of Education and Research (ger. Bundesministerium für Bildung und Forschung - BMBF) with 2.3 million euros as part of the Integrated Water Resources Management (ger. Integriertes Wasserressourcen-Management - IWRM) funding measure under the "Research for Sustainability" (ger. Forschung und Nachhaltigkeit - FONA) strategy. 

The project results of the second project phase are summarised in the SALAM Brochure (external link). In this project, the Chair of ABWL and Production Management was responsible for a multi-criteria evaluation of water production and management variants and a techno-economic analysis of water infrastructure projects. In addition, the chair was involved in the creation of a regional macro model for transboundary water resource planning. 

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

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.

04.10.2020 New Publication: Life Cycle Assessment of Synthetic Natural Gas Production from Different CO2 Sources: A Cradle-to-Gate Study

Life Cycle Assessment of Synthetic Natural Gas Production from Different CO2 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.

Schröder, T.; Geldermann, J.:
Improving planning by integrating spatial data into decision support systems. 

Journal of Decision Systems (2019) [Paper]

Abstract
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]

Abstract
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.
