By leveraging the concentrated solar power capabilities of DSSs, this research examines their performance relative to alternative solutions such as photovoltaic (PV) systems and solar heating. A 25 kW Stirling Energy Systems (SES) DSS served as the basis for the analysis. Simulations were performed for local 2022 weather conditions in Germany. The study employed a detailed modeling approach using the NREL System Advisor Model (SAM) to quantify the energy outputs and evaluate the system efficiencies. The results indicate that the DSS achieved an electrical efficiency of 25% and a combined efficiency of 78% when accounting for the maximum thermal energy generated. Seasonal analysis highlights the adaptability to fluctuating energy demands, with advantages in winter heating applications. Comparative evaluations revealed DSSs as a viable cogeneration alternative to standalone PV systems and solar heaters, offering reduced environmental impacts and enhanced energy efficiency. Future work will address real-world operational conditions, including thermal storage and multigeneration integration, positioning the DSS as a sustainable solution for renewable energy generation.","lang":"eng"}],"status":"public","publication":"Sustainability","issue":"3","user_id":"83781","date_created":"2025-12-11T13:57:43Z","date_updated":"2025-12-11T14:01:17Z","doi":"10.3390/su17031257","year":"2025","conference":{"name":"12th European Conference on Renewable Energy Systems","end_date":"2024-05-17","start_date":"2024-05-16","location":"Mallorca / Spain "},"citation":{"din1505-2-1":"<span style=\"font-variant:small-caps;\">Klepp, Georg Heinrich</span>: Solar Stirling for Renewable Energy Multigeneration Systems.

Electric vehicles (EVs) are a promising alternative, but the issue lies in establishing efficient and environmentally friendly charging infrastructure. This review explores the existing research on the subject of photovoltaic-powered electric vehicle charging stations (EVCSs). Our analysis highlights the potential for economic growth and the creation of robust and decentralized energy systems by increasing the number of EVCSs. This review summarizes the current knowledge in this field and highlights the key factors driving efforts to expand the use of PV-powered EVCSs. The findings indicate that MATLAB was predominantly used for theoretical studies, with projects focusing on shading parking lots. The energy usage varied from 0.139 to 0.295 kWh/km, while the cost of energy ranged from USD 0.0032 to 0.5645 per kWh for an on-grid system. The payback period (PBP) values are suitable for this application. The average PBP was demonstrated to range from 1 to 15 years. The findings from this assessment can guide policymakers, researchers, and industry stakeholders in shaping future advancements toward a cleaner and more sustainable transportation system.","lang":"eng"}],"publication_status":"published","status":"public","issue":"5","publication":"World Electric Vehicle Journal"},{"publication_identifier":{"isbn":["978-3-319-79729-8","978-3-319-25069-4"],"eisbn":["978-3-319-25071-7"]},"title":"From the Concept to the Tap - Integrated Water Resources Managment in Northern Namibia","status":"public","publication":"Integrated Water Resources Management: Concept, Research and Implementation","publisher":"Springer ","author":[{"first_name":"Stephan","full_name":"Lier, Stephan","last_name":"Lier"},{"last_name":"Brenda","first_name":"Maria","full_name":"Brenda, Maria"},{"last_name":"Cornel","first_name":"Peter","full_name":"Cornel, Peter"},{"last_name":"Deffner","first_name":"Juta","full_name":"Deffner, Juta"},{"id":"81335","last_name":"Felmeden","full_name":"Felmeden, Jörg","first_name":"Jörg"},{"first_name":"Alexander","full_name":"Jokisch, Alexander","last_name":"Jokisch"},{"first_name":"Thomas","full_name":"Kluge, Thomas","last_name":"Kluge"},{"full_name":"Müller, Katherina","first_name":"Katherina","last_name":"Müller"},{"last_name":"Röhrig","first_name":"Julian","full_name":"Röhrig, Julian"},{"first_name":"Vanessa","full_name":"Stibitz, Vanessa","last_name":"Stibitz"},{"last_name":"Urban","full_name":"Urban, Wilhelm","first_name":"Wilhelm"}],"publication_status":"published","abstract":[{"lang":"eng","text":"Namibia is the most arid country in Sub-Saharan Africa. The Cuvelai-Etosha Basin (CEB) in central northern Namibia in particular is experiencing various ecological and social-ecological challenges such as high climate variability, saline groundwater, dependence on Angola for freshwater supply, high population growth and density, and increasing urbanisation. These challenges make water supply and management difficult and threaten the livelihood of the local population and the health of the ecosystem. Facing up to these challenges, the German-Namibian research project CuveWaters has developed, adapted and set up different technologies as pilot plant s. The Integrated Water Resources Management (IWRM) concept of CuveWaters is based on a multi-resource-mix in which water is obtained from different sources (rainwater, floodwater, groundwater and wastewater) and used for various purposes. High quality water is used as drinking water; water of a relatively low quality is used for irrigation. In cooperation with the residents of four villages and one small town, the project partners are implementing different technologies to collect and store, produce, treat and reuse water. The implemented technologies are rain- and floodwater harvesting, groundwater desalination, and the combination of sanitation, wastewater treatment and water reuse. The aim is to improve peoples’ livelihood through research on innovative and adapted solutions which contribute to a successful and adapted application of IWRM. To this end, the project integrates science, technology and societal aspects in a transdisciplinary research approach by linking scientific knowledge from natural, engineering and social sciences with the everyday practices and know-how of the stakeholders involved. Thus, the technical aspects are complemented by a wide range of societal and scientific components, such as capacity development, monitoring, participation or knowledge management. These ensure societal embedding of the technologies and knowledge transfer. This paper will illustrate the transdisciplinary approach, implemented technologies and accompanying measures as well as key results."}],"year":"2016","editor":[{"last_name":"Borchardt","full_name":"Borchardt, Dietrich","first_name":"Dietrich"}],"citation":{"havard":"S.
