Title:

Towards a Smart City Playground for Research and Experimentation of Energy Use Cases in a University Campus Setting
Authors:

Nikolay Tcholtchev, Martin Gergeleit, Stephan Böhm, Heinz Werntges and Holger Hünemohr
Abstract: The current paper describes our planned activities towards establishing an experimentation platform for energy management as part of our research and teaching activities at the RheinMain University of Applied Sciences (UAS) in Wiesbaden, Germany. Our vision is to establish a data platform that gathers energy related data and information from various sources, including sensors, weather data, existing energy management systems, open data platforms and different research data sets available for the community. In order to transfer the data to the data platform, different communication protocols (e.g. MQTT, 5G/6G, LoRaWAN, WiFi, CoAP, 6LoWPAN …) and data models/formats (NGSI-LD, XML, JSON, SensorThings …) should be put in place and utilized in a campus setting, such that data and information can flow into the logically centralized data platform. Our vision is to follow established smart city (pre-)standards for Open Urban Platforms, such as the DIN SPEC 91357, DIN SPEC 91397 and DIN SPEC 91377. By following such open modular approaches, we want to enable a framework of different software and hardware components as well as datasets, which can be used for teaching (e.g. in seminars and lectures) as well as for research activities in the course of PhD projects.

Authors:

Stanislav Misak, Lukas Prokop, Vojtech Blazek, Ivo Pergl and Mohit Bajaj
Abstract: The Centre for Energy and Environmental Technologies – Explorer (CEETe) is a research platform combining research and development of cross-sectoral cooperation in sustainable energy, aiming to transfer innovative technologies to ensure energy self-sufficiency and raw material independence in the European context. Its interdisciplinary approach enables the efficient decarbonisation of industrial processes, the optimisation of the use of renewable energy sources and the implementation of circular economic models. CEETe's research activities include advanced energy technologies and environmental processes, with key areas being combustion modelling, hydrogen technology development and energy storage. The Centre is actively involved in international research projects and technology transfer to industry. This article provides an overview of the key research areas, current projects and future directions of CEETe's scientific activities, emphasising the integration of advanced technological solutions for sustainable energy and environmental management.

Title:

Modeling and Simulation of Ethanol Steam Reforming for Sustainable Hydrogen Production
Authors:

Luca Cimmino, Francesco Calise, Francesco Liberato Cappiello, Massimo Dentice d’Accadia and Maria Vicidomini
Abstract: The transition toward sustainable energy systems emphasizes hydrogen as a clean energy carrier, with ethanol steam reforming emerging as a promising pathway for its renewable production. This study presents a one-dimensional reactor model developed and simulated using MatLab, integrating thermodynamic, kinetic, and heat transfer analyses to evaluate the performance of ethanol reforming. The model was validated against existing literature and simulated under varying operational parameters. Key numerical results indicate that the reactor achieves a hydrogen yield of 85% and an energy efficiency exceeding 75% at optimal conditions, with inlet temperatures of 600°C and an ethanol-to-water molar ratio of 1:3. Sensitivity analysis revealed that increasing the ethanol flow rate from 0.1 to 0.3 mol/s reduced the hydrogen yield by 12%, while adjusting the reactor diameter from 0.05 m to 0.1 m improved the thermal efficiency by 10%. The system performance was also significantly influenced by heat transfer coefficients, which ranged from 500 to 800 W/m²·K along the reactor. The study also highlights the potential of integrating carbon capture technologies to mitigate CO2 emissions generated as a byproduct. These findings provide valuable insights for optimizing ethanol reforming reactors, paving the way for scalable and sustainable hydrogen production technologies in renewable energy systems.

Title:

Dynamic Simulation Model of a Renewable Energy Community for Small Municipalities
Authors:

Francesco L. Cappiello, Luca Cimmino, Chiara Martone and Maria Vicidomini
Abstract: The presented paper describes the dynamic simulation model developed to predict the real time operation of a Renewable Energy Community based on PV panels coupled with energy storage systems. The dynamic model is able to evaluate the self-consumed energy of the community as well as the energy delivered to the grid considering a real electric load of the community. The model is able to evaluate in detail the economic feasibility of the plant, according to a comprehensive economic analysis, based on the Italian regulation. TRNSYS software is used to model the included energy components. The model is applied to a suitable case study, the municipality of Foiano di Val Fortore, located in the south of Italy. The main results of the presented analysis highlight that the photovoltaic panels lead to a reduction of the primary energy consumption of the renewable energy community by 32%. Due to incentives the achieved simple payback is extremely low. In fact, when the energy storage system is not considered, the achieved simple payback is equal to 4.0 years. When the PV panels are coupled with the energy storage system, the simple payback reaches the value of 13.5 years.
