Projekt-Sachbericht WIR! h2-well Wasserstoffquell- und Wertschöpfungsregion Main-Elbe-LINK
No full textDas Teilvorhaben wurde im Rahmen des Verbundvorhabens "h2well‐compact – Kompaktes Wasserstoffversorgungssystem für dezentrale Mobilitätsanwendungen" durch die Höschel & Baumann Elektro GmbH durchgeführt und verfolgte das übergeordnete Gesamtziel des Verbundvorhabens, technische Komponenten für eine dezentral organisierte Wasserstoffwirtschaft zu entwickeln und zu erproben. Im Teilvorhaben sollte dabei, eine teilstandardisierte, technische Lösung entwickelt werden, über die die Versorgung eines dezentralen Wasserstoffversorgungssystems mit erneuerbarer Elektrizität aus kleinskaligen, regionalen Erneuerbaren-Energien-Anlagen realisiert werden kann. Diese teilstandardisierte, technische Lösung sollte modellhaft anhand der Kleinwasserkraftanlage der Antragstellerin im Leistungsbereich < 100 kW umgesetzt und bezüglich der Leistungsfähigkeit und Ressourcen- sowie Energieeffizienz in einem Probebetrieb, untersucht werden. Dabei wurden die folgenden Arbeitsziele verfolgt:
- die elektro- sowie regelungs- und steuerungstechnischen Infrastruktur der Kleinwasserkraftanlage in Bezug auf die Anbindung von Elektrolysesystemen zu analysieren und zu bewerten sowie ein teilstandardisiertes Schaltschranksystem zur Herstellung der Anbindungsmöglichkeit von Elektrolysesystemen an bestehenden Erneuerbaren-Energien-Anlagen zu konzipieren,
- ein regelungstechnisches Anlagenkonzept der Kleinwasserkraftanlage zur Abbildung von Betriebsregimen für den Probebetrieb zur Erforschung des Gesamtsystems unter realen Nutzungsbedingungen zu entwickeln,
- erneuerbare Elektrizität für den Betrieb eines kompakten PEM‐Druckelektrolyseurs und eines trailerbasierten Verdichters durch die Kleinwasserkraftanlage bereitzustellen und
- die Kleinwasserkraftanlage im Zusammenhang mit dem Gesamtsystem unter realen Nutzungsbedingungen zu betreiben und den Betrieb elektrotechnisch zu optimieren und die Betriebsdaten auszuwerten.
Die gesetzten Arbeitsziele konnten aufgrund des zeitlich eingeschränkten Probebetriebes nicht vollständig erreicht werden, weshalb weiterer Forschungsbedarf besteht.
Datei-Upload durch TIBThe sub-project was carried out by Höschel & Baumann Elektro GmbH as part of the joint project ‘h2well-compact - Compact hydrogen supply system for decentralised mobility applications’ and pursued the overall objective of the joint project to develop and test technical components for a decentralised hydrogen economy. The aim of the sub-project was to develop a partially standardised technical solution that could be used to supply a decentralised hydrogen supply system with renewable electricity from small-scale, regional renewable energy plants. This partially standardised, technical solution was to be implemented as a model using the applicant's small hydropower plant in the < 100 kW output range and examined in terms of performance and
resource and energy efficiency in a trial operation. The following objectives were pursued:
- to analyse and evaluate the electrical and control infrastructure of the small hydropower plant with regard to the connection of electrolysis systems and to design a partially standardised control cabinet system for the connection of electrolysis systems to existing renewable energy plants,
- to develop a control system concept for the small hydropower plant to map operating regimes for trial operation to investigate the overall system under real conditions of use,
- to provide renewable electricity for the operation of a compact PEM pressurised electrolyser and a trailer-based compressor by the small hydropower plant and
- to operate the small hydropower plant in connection with the overall system under real conditions of use and to optimise the operation in terms of electrical engineering and evaluate the operating data.
The set work objectives could not be fully achieved due to the time-limited trial operation, which is why further research is required
Open Research Knowledge Graph
No full textAs we mark the fifth anniversary of the alpha release of the Open Research Knowledge Graph (ORKG), it is both timely and exhilarating to celebrate the significant strides made in this pioneering project. We designed this book as a tribute to the evolution and achievements of the ORKG and as a practical guide encapsulating its essence in a form that resonates with both the general reader and the specialist. The ORKG has opened a new era in the way scholarly knowledge is curated, managed, and disseminated. By transforming vast arrays of unstructured narrative text into structured, machine-processable knowledge, the ORKG has emerged as an essential service with sophisticated functionalities. Over the past five years, our team has developed the ORKG into a vibrant platform that enhances the accessibility and visibility of scientific research. This book serves as a non-technical guide and a comprehensive reference for new and existing users that outlines the ORKG’s approach, technologies, and its role in revolutionizing scholarly communication. By elucidating how the ORKG facilitates the collection, enhancement, and sharing of knowledge, we invite readers to appreciate the value and potential of this groundbreaking digital tool presented in a tangible form. Looking ahead, we are thrilled to announce the upcoming unveiling of promising new features and tools at the fifth-year celebration of the ORKG’s alpha release. These innovations are set to redefine the boundaries of machine assistance enabled by research knowledge graphs. Among these enhancements, you can expect more intuitive interfaces that simplify the user experience, and enhanced machine learning models that improve the automation and accuracy of data curation. We also included a glossary tailored to clarifying key terms and concepts associated with the ORKG to ensure that all readers, regardless of their technical background, can fully engage with and understand the content presented. This book transcends the boundaries of a typical technical report. We crafted this as an inspiration for future applications, a testament to the ongoing evolution in scholarly communication that invites further collaboration and innovation. Let this book serve as both your guide and invitation to explore the ORKG as it continues to grow and shape the landscape of scientific inquiry and communication
