    <title language="eng">On the porosity-dependent permeability and conductivity of triply periodic minimal surface based porous media</title>
    <abstract language="eng">With the fast development in the field of additive manufacturing, triply periodic minimal surface (TPMS) based porous media have recently found many uses in mechanical property tuning. However, there is still a lack of understanding in their porosity-dependent permeability and electrical as well as thermal conductivity. Here, we perform finite volume simulations on the solid and void domains of the Schoen gyroid (SG), Schwarz primitive (SP) and Schwarz primitive beam (SPB) TPMS with porosities between 63% and 88% in Ansys Fluent. A simple cubic lattice (CL) of equivalent porosity served as reference. The SPB and CL showed up to one order of magnitude higher permeabilities than the SG and SP. However, SG and SP have about 1.3 and 2.6 times the electrical and thermal conductivity of SPB and CL, respectively. Furthermore, the properties of SPB and CL are largely affected by the surface area density, whereas tortuosity variation does not impact permeability and conductivity to a major extent. Finally, empirical relations are adapted to describe the presented data and thus, they may enable future designers of TPMS based porous structures to fine-tune the geometries according to the requirements on permeability and electrical as well as thermal conductivity.</abstract>

    <abstract language="deu">Was ist QI?&#13;
Qualitätsinfrastruktur – Das Zusammenwirken von nationalen Institutionen im Bereich der Metrologie, Normung und Standardisierung, Akkreditierung, Konformitätsbewertung und Marktüberwachung, mit dem Ziel die Qualitätssicherung bei Produkten und Prozessen in Deutschland zu gewährleisten.&#13;
Unser Ziel ist es, unsere bewährte Qualitätsinfrastruktur (QI) noch besser zu machen und so einen Beitrag zur Lösung von sozioökonomischen, ökologischen und technologischen Herausforderungen unserer Zeit zu leisten. Eine der bedeutendsten technologischen Herausforderungen unserer Zeit ist die Digitalisierung. Die zentralen Akteure der deutschen QI wollen diese digitalisieren. Beteiligte Institutionen sind aktuell BAM (Konformitätsbewertungen in bestimmten Bereichen), DAKKS (Akkreditierung),  DIN/DKE (Normung), PTB (Metrologie). Wir wollen also ein Reallabor errichten, das die Wertschöpfungskette einer Tankstelle abbildet, also eine Wasserstofftankstelle beinhaltet, die dann mit erweiterter Sensorik ausgestattet werden soll. Somit sollen digitale Prozesse abgebildet werden können sowie sensorgestützte Verfahren zur qualitätsgesicherten Datenerfassung und -auswertung genutzt werden. Diese gesammelten Daten sollen dann in eine Dateninfrastruktur eingehen und mithilfe eines Datenmanagementsystems sowie künstlicher Intelligenz in einem Digitalen Zwilling zusammenlaufen, der die digitale Prozessüberwachung der Sicherheit möglich macht. Schließlich sollen die in QI Digital entwickelten digitalen Strukturelemente der QI erprobt werden, insbesondere die QI Cloud, Smart Standards und digitalen Zertifikate. Im Zusammenspiel ermöglicht das unter anderem die Entwicklung von Predictive Maintenance Verfahren für:&#13;
1. die Optimierung von Wartungszyklen und Minimierung von Ausfallzeiten&#13;
Erhöhung der Betriebssicherheit durch frühzeitige Identifikation kritischer Zustände im Gesamtsystem&#13;
2. Entwicklung verlässlicher Qualitäts- und Sicherheitsstandards &#13;
3. Digital-gestützte Risikobeurteilung und Konformitätsbewertung&#13;
Die im Pilotprojekte betrachteten Sicherheitsaspekte sind also zusammenfassbar als:&#13;
a) Auswirkungsbetrachtungen bei möglichen Fehlfunktionen oder Defekten&#13;
b) Die genannte vorrauschauende Instandhaltung und damit verbundene Lebensdauerprognose, die in Kombination eine bessere allgemeine Verfügbarkeit garantieren sollen&#13;
Als Grundlage hierfür benötigen wir aber Änderungen im Bereich der technischen Regeln und Normen, um die neuen digitalen Werkzeuge zuzulassen und nutzbar zu machen.</abstract>

    <abstract language="eng">BAM is part of the “Quality Infrastructure Digital” (QI Digital) initiative of the German Federal Ministry for Economic Affairs and Climate Action (BMWK). This initiative aims at coordinating a large cooperation project, “QI Digital” for making German and European quality management systems fit for the digital transformation. It is a fact that the digitization of new products and services is occurring much faster than quality management systems can be accordingly updated. Thus, the digital transformation of quality management is necessary to preserve the competitiveness of the German and European industries that stand for quality and safety in the global market. The Use Case “Reliable Hydrogen Refueling Station” of QI Digital aims at creating new solutions that are transferable to other technical systems and at further developing standards and technical rules as a contribution to technology transfer and innovation.</abstract>

    <title language="deu">Aspekte einer digitalen Lebenslaufakte (Impulsvortrag)</title>
    <abstract language="deu">Durch Einsatz neuer Technologien im Transport von komprimiertem Wasserstoff konnte eine Verdreifachung des Nutzlastverhältnisses erreicht werden. Diese neuen Speicher auf den Transportfahrzeugen müssten aber anders auf ihre Sicherheit überprüft werden, als dies heute gefordert wird. &#13;
Mit dem Markthochlauf Wasserstoff vervielfacht sich zudem die Anzahl der Transporteinheiten. Da sich im Zuge der neuen H2-Transportfahrzeuge aber auch die Anzahl der einzelnen Speicher pro Fahrzeug etwa verzwanzigfacht hat, kommen die Kapazitäten für die erforderliche wiederkehrende Prüfung an ihre Grenzen.&#13;
Dies könnte evtl. durch eine entsprechende Erhöhung der Prüfkapazitäten gelöst werden. Da dies aber weder praktisch machbar ist noch technisch wirklich sinnvoll, müssen alternative Ansätze z.B. durch digital erfasste zerstörungsfreie Prüfkonzepte gesucht werden. Hierzu bedarf es aber einer Lebenslaufakte, die beginnend von der Definition einer Bauweise über die Baumusterprüfung, Zulassung, Herstellung, erstmalige Prüfung, Verwendung und wiederkehrenden oder begleitenden Prüfungen bis zum Verschrotten alle Daten erfassen und verwalten kann. &#13;
Eine solche Lebenslaufakte könnte auch als eine Art digitaler Produktpass (DPP) verstanden werden.</abstract>

    <title language="eng">Risk management and consequence control in hydrogen transport - volume dependent pressure limitation as a scientific approach for consequence control</title>
    <abstract language="eng">With technological development, the transport units for compressed gases are becoming larger and their number is increasing. Simultaneously, the filling pressure for hydrogen in transport has increased far beyond the 200 bar, which has been the common European standard for decades. In total, this increases the potential consequences of an incident, which needs to get limited for ensuring acceptance in current practice with pressure vessels from large serial production. &#13;
Consequently, the measures for new developments of extremely large and highly pressurised pressure vessels should meet a risk based higher level of requirements. For this purpose, the so-called pressure-volume product was proposed as a safety related criteria to the relevant regulatory bodies in 2020. The approach was accepted, and a working group was set up at the United Nations for developing a broadly accepted limitation of today's established pressure vessels compared to future units with even more gas content. The path to the finally decided limit value of 1.5 million bar litres is presented here for hydrogen with its individual steps: ‘Boundary between major accident and disaster’, ‘The effect of pressure waves on the human body’, ‘The propagation of pressure waves’, ‘The reference value for population density’ and ‘Impact of pressure waves’. This result of the UN working group has been accepted in December 2023 and will lead to a binding limitation of the pressure volume product for the so called pressure receptacles by 2027. The work on units larger than this pV-limit is going on at ISO level.</abstract>

    <title language="eng">Safety assessment of MLI super-insulation systems for cryogenic liquid-hydrogen tanks in fire scenarios</title>
    <abstract language="eng">In the context of green energy transition, cryogenic tanks featuring MLI systems are emerging as a leading solution to store hydrogen in heavy-duty vehicles. However, the integrity of such tanks can be jeopardized by fire. In such a scenario, MLI materials degradation can occur, leaving the tank unprotected from the fire heat flux, with consequent rapid pressurization and a high risk of failure. This study presents an assessment of aluminum-based MLI for liquid hydrogen cryogenic tanks under fire exposure based on the estimation of the time to mechanical failure of the equipment. This is calculated through an innovative model that simulates the thermomechanical response of the tank, including the MLI thermal degradation and the pressure-relief valve (PRV) operation. The application to several case studies that consider a typical LH2 tank featuring a wide range of MLI configurations demonstrated the likelihood of failure in case of exposure to a hydrocarbon pool fire, providing also comprehensive insights into the impact of the insulation characteristics and operating conditions on the time to failure.</abstract>

    <title language="eng">Testing of vacuum insulation panels for liquefied hydrogen storage tanks</title>
    <abstract language="eng">For the future use of liquefied hydrogen (LH2) as a green energy carrier, new concepts for storage tanks and in particular their insulation are necessary. The methodology applied in current LH2 tanks has some disadvantages while manufacturing and operation of large tanks that may be required in the future. While liquefied natural gas tanks exist in the necessary capacities, they are incompatible with LH2 due to its significantly lower storage temperature. In this paper, the possibility of using vacuum insulation panels (VIPs) as an alternative to the conventional double walled, powder filled vacuum insulation is presented. The two systems are introduced and compared on a conceptual level with a focus on the loss of vacuum failure mode. Furthermore, a test rig that enables the testing and quantification of thermal properties of VIP based insulations in ordinary and loss of vacuum conditions is presented. The test rig is a boil-off calorimeter using liquefied nitrogen and features a square cold surface with a side length of 3 m. An overview over the planned testing and its goals is given.</abstract>

    <title language="eng">Effective elastic moduli and failure mechanisms of a random assembly of thin walled glass microbubbles</title>
    <abstract language="eng">In this work a methodology is presented to estimate the elastic properties and failure mechanisms of an assembly of random, brittle microbubbles. The approach is based on the mechanics of frictionless micro-contact between hollow spherical shells by employing relations from classical shell theory and verified by two dimensional axisymmetric Finite Elements. The estimated values are in agreement with available experimental values. Moreover, a granular type analytical homogenization model provides an isotropic elastic constitutive law to be used for the macroscopic deformation of an assembly of glass micro-bubbles when it is compressed by external loads. In addition, approximate estimates are also proposed for two important micro-failure mechanisms of such assemblies that relate either to the splitting or to the buckling of a brittle spherical shell, prior its complete crushing. The results are novel and are expected to enhance the application of glass microbubbles directly in acute thermal insulation problems such as liquid hydrogen storage.</abstract>

    <title language="deu">Die volumenabhängige Druckbegrenzung als Maßnahme zur Konsequenzsteuerung im Wasserstofftransport</title>
    <abstract language="deu">Mit der technologischen Entwicklung werden auch die Transporteinheiten für Druckgase größer und die zu transportierenden Gase wie Wasserstoff deutlich über die lange als Standard geltenden 200 bar hinaus komprimiert. Damit steigt das Konsequenzpotenzial eines Zwischenfalls, das nun begrenzt werden soll, um die bisherige Praxis mit wenigen Zwischenfällen von den Maßnahmen für die neuen Entwicklungen extrem großer Transportdruckbehälter abgrenzen zu können.&#13;
Hierzu wurde – ausgehend von einer technologisch und sicherheitstechnisch störenden Begrenzung des Volumens von Bergungsdruckgefäßen – das sogenannte Druck-Volumen-Produkt als Kenngröße und Konsequenzmaß vorgeschlagen. Um eine breit akzeptierte Abgrenzung der heute etablierten Druckgefäße gegenüber den zukünftigen Einheiten mit noch mehr Gasinhalt erarbeiten zu können, wurde eine Arbeitsgruppe bei den Vereinten Nationen eingerichtet, deren Weg zu ihrem Ergebnis „Einführung einer Obergrenze von 1.5 Mio. bar-Liter für das Druck-Volumen-Produkt von Druckgefäßen“ mit den Wasserstoff-&#13;
spezifischen Einzelschritten „Grenze zwischen Großunfall und Katastrophe“, „Die Wirkung von Druckwellen auf den menschlichen Körper“, „Die Ausbreitung von Druckwellen“, „Der&#13;
Referenzwert für die Bevölkerungsdichte“ und „Die Druckwellenberechnung“ hier dargestellt ist. Dieses Ergebnis der UN-Arbeitsgruppe wird bis 2027 zu einer verbindlichen Begrenzung&#13;
des Druckvolumenproduktes in Druckgefäßen führen.</abstract>

    <title language="eng">Comparative life cycle assessment of different vacuum insulation panel core materials for cryogenic storage tanks – with a focus on glass bubbles as a novel core material</title>
    <abstract language="eng">Developing a sustainable hydrogen supply chain is important in facilitating the energy transition towards climate neutrality. Hydrogen in its free form can be stored and transported either as a gas or a liquid. Due to gaseous hydrogen's comparatively low energy density, liquefied hydrogen (LH 2) is often preferred, especially with regard to long-distance transportation and storage in bulk. A notable challenge associated with LH2 is the inherent requirement to preserve it at a low temperature of -253°C. Consequently, the utilisation of thermally insulated tanks is necessary to minimise LH 2 evaporation. There is a lack of literature on the environmental impacts of insulation materials and concepts for cryogenic storage tank applications in the hydrogen supply chain. Hence, this study investigates a novel concept, namely vacuum insulation panels (VIPs), focusing on their core materials, with a view to assessing their environmental sustainability and circularity. A cradle-to-grave life cycle assessment (LCA) model is employed to investigate six distinct VIP core materials, namely, silica aerogel, rigid polyurethane foam, expanded perlite, glass fibre, fumed silica, and glass bubbles (hollow glass microspheres), with a special focus on the latter. The LCA results show that polyurethane foam and silica aerogel rank low in environmental performance, making them less suitable as primary choice. Expanded perlite is the most environmentally friendly material option, followed by glass fibre, glass bubbles, and fumed silica. Improvements to the environmental impact of glass bubbles can be achieved via the implementation of closed-loop recycling in their life cycle.</abstract>

    <title language="eng">A Comprehensive Numerical Study of the Behaviour of an LH2 Storage Tank in the Event of a Fire</title>
    <abstract language="eng">As the world moves towards green energy production, effective storage and transportation solutions become essential. To support this transition, energy carriers with minimal or zero environmental impact are required. Liquified hydrogen represents a promising candidate due to its emissions-neutral properties. However, its highly flammable nature necessitates adherence to strict safety codes and standards. Storing hydrogen often requires advanced super-insulation materials. To enhance the safety of cryogenic hydrogen storage tanks under extreme conditions, such as those encountered during fire accidents, it is crucial to understand the thermal behaviour of the tank. Predicting pressurization and potential failure in advance demands a robust and comprehensive model. However, still such models suffer lack of detailed heat transfer models which account for various sub-processes during an accident scenario. Hence, this study introduces a comprehensive model for the pressurization of cryogenic tanks equipped with multi-layer insulation (MLI) systemsin the event of fire, which comprises several sub-models. These sub-models account for heat transfer phenomena through the thermal insulation at nominal conditions and its thermal degradation during fire exposure, the fluid, the internal pressurization, and the performance of the pressure relief valve. This study provides valuable insights into the safety and the behaviour of hydrogen storage tanks under thermal loads.</abstract>

    <title language="eng">A modular concept for protection against debris flight - Design, properties and usage</title>
    <abstract language="eng">With advances in technological development, stationary and mobile storage units for compressed hydrogen are becoming larger and larger. Their number is also increasing. At the same time, their design has evolved from steel and aluminium to pressure vessels made of composite materials. For safety reasons the design approval of those composite cylinders requires fire engulfment tests, which are mainly organised as open-air tests always needs dedicated protection measures. Under some conditions those protections measures even reduce the effort for organisational safety measures if e.g. the emission of splinters can get totally prevented. Another aspect is the improved reproducibility of fire tests by reducing the influence of wind, especially wind turbulence. Between 2017 and 2019, BAM developed a stackable protective frame made of steel to safely capture splinters for the safe execution of high-energy impact tests. However, this frame was not flexible enough for the follow up project, which led to a completely new protection concept for (potentially) destructive tests on gas-filled pressure vessels. This concept is based on very robust building blocks with knobs and holes of a dimension of 1m x 0.5m x 0.5m made from welded steel. Despite their considerable weight of around 500 kg, they can be combined and stacked very easily like ‘Lego bricks’. The presentation will show the flexibility of the concept, some results of tests on the robustness against pressure waves and the effectiveness in wind attenuation. Finally, the interaction with a new, also modular burner concept for localised fires and full engulfment fires will be presented.</abstract>

    <title language="eng">Safety challenges of the hydrogen market ramp-up</title>
    <abstract language="eng">The presentation will provide some thoughts on the key safety challenges for staying safe during the market ramp-up phase of the rapidly expanding hydrogen economy. The focus is on storage aspects, but other topics are also covered. Each brief description of an aspect is followed by a proposal for solving the problem. Key words are safety aspects of hydrogen transport (CGH2 and LH2), risk control, consequence limitation, structural reliability control, safety monitoring through destructive and non-destructive testing, improvement of RCS through impact simulation, new approaches to safety assessment, outlook on the potential of NDT and digital product passports.</abstract>

    <title language="eng">Comparative performance assessment of multilayer insulation (MLI) systems for liquid hydrogen vessels in fire scenarios</title>
    <abstract language="eng">Multilayer Insulation (MLI) systems are a mature technology for cryogenic liquid hydrogen (LH2) tank thermal insulation. Recent tests evidenced that MLI materials may be damaged when exposed to fire, resulting in critical safety issues in the case of accidents. Thus, an innovative approach to the performance assessment of aluminum and polyester-based MLIs for LH2 tanks in fire scenarios was developed. A specific model integrating the  hightemperature degradation of MLIs and the thermodynamic modeling of the tank lading was coupled to specific key performance indicators. Results of the analysis applied to a vehicle-scale tank equipped with 80 MLI layers indicate that MLI degradation and consequent tank failure may occur in less than 20 min for external shell temperatures above 1160 K in the presence of full engulfment, regardless of insulation used. Conversely, degradation does not occur earlier than 3600s below 603 and 928 K for polyester and aluminum-based MLI, respectively.</abstract>

    <title language="eng">Repeatable testing of a cryogenic storage tank with variable insulation material in fire like conditions</title>
    <abstract language="eng">For decarbonizing the energy industry and transport, cryogenic energy carriers have great potential. The storage takes place in tanks with thermal super-insulations, which are in application for decades, but there is only limited knowledge about its behaviour in a fire scenario. This represents a major incident that may generate extraordinary loads on the tank and its insulation system, and that eventually lead to a sudden tank failure. This paper presents a test rig called the Cryogenic High Temperature Thermal Vacuum Chamber (CHTTVC), which can be used to test typical thermal superinsulation’s under cryogenic and fire-like conditions in parallel. The test method makes it possible to measure the heat flow through the thermal superinsulation over time and to investigate the degradation behaviour of the insulation within a test. In the paper results from the first tests are presented.</abstract>

    <title language="eng">Cryogenic storage system behaviour under fire : A study of the insulation impact</title>
    <abstract language="eng">The transition from fossil fuels to low-emission alternatives is essential to mitigate carbon emissions in energy-intensive sectors. Liquid hydrogen (LH2) is a promising energy carrier due to its high gravimetric energy density, but its storage requires advanced insulation to minimize heat ingress and prevent excessive boil-off losses. Multilayer insulation (MLI), perlite, and microspheres are commonly used under vacuum conditions, yet their performance under fire exposure remains a critical concern. This study investigates the thermal degradation of insulation materials and its impact on heat transfer in an event with extreme thermal load conditions using the Cryogenic High-Temperature Thermal Vacuum Chamber (CHTTVC). The heat flow dynamics are analyzed, and an equivalent heat transfer coefficient is proposed to quantify the impact of insulation deterioration as the outer wall temperature increases. Additionally, a novel liquid-vapor interface monitoring method is introduced to improve real-time detection of phase changes within the tank. The results highlight that insulation failure substantially increases the heat flow, which, if not mitigated, can lead to boiling liquid expanding vapor explosions (BLEVE), jet fires, or catastrophic tank failure. The findings provide valuable insights into optimizing LH2 storage safety and improving emergency response strategies for cryogenic tanks exposed to extreme thermal conditions.</abstract>

    <title language="eng">Repeatable Testing of a Cryogenic Storage Tank with Variable Insulation Material in Fire Like Conditions</title>
    <abstract language="eng">For decarbonizing the energy industry and transport, cryogenic energy carriers have great potential. The storage takes place in tanks with thermal super-insulations, which are in application for decades, but there is only limited knowledge about its behaviour in a fire scenario. This represents a major incident that may generate extraordinary loads on the tank and its insulation system, and that eventually lead to a sudden tank failure. This paper presents a test rig called the Cryogenic High Temperature Thermal Vacuum Chamber (CHTTVC), which can be used to test typical thermal superinsulation’s under cryogenic and fire-like conditions in parallel. The test method makes it possible to measure the heat flow through the thermal superinsulation over time and to investigate the degradation behaviour of the insulation within a test. In the paper results from the first tests are presented.</abstract>

    <title language="eng">Testing of vacuum insulation panels for liquefied hydrogen storage tanks</title>
    <abstract language="eng">For the future use of liquefied hydrogen (LH2) as a green energy carrier, new concepts for storage tanks and in particular their insulation are necessary. The methodology applied in current LH2 tanks has some disadvantages while manufacturing and operation of large tanks that may be required in the future. While liquefied natural gas tanks exist in the necessary capacities, they are incompatible with LH2 due to its significantly lower storage temperature. In this paper, the possibility of using vacuum insulation panels (VIPs) as an alternative to the conventional double walled, powder filled vacuum insulation is presented. The two systems are introduced and compared on a conceptual level with a focus on the loss of vacuum failure mode. Furthermore, a test rig that enables the testing and quantification of thermal properties of VIP based insulations in ordinary and loss of vacuum conditions is presented. The test rig is a boil-off calorimeter using liquefied nitrogen and features a square cold surface with a side length of 2 m. An overview over the planned testing and its goals is given.</abstract>

    <title language="eng">New concepts in liquid hydrogen storage</title>
    <abstract language="eng">On the way to the energy transition, cryogenic fluids such as Liquefied Hydrogen (LH2) or Liquefied Natural Gas (LNG) are very important. They enable the large-scale economic transport and storage of energy as well as they represent alternative fuels for energy-intensive mobile applications such as aircrafts, ships and HGVs. For the last one, the number of vehicles and fuel stations has increased rapidly in the last 10 years all over Europe. Does this also entail new risks, for instance from a BLEVE in case of fires? To answer this question, BAM has conducted several research projects over the last decades and intensified the research recently with several experimental, numerical, and empirical outcomes on how a tank with insulation behaves in a fire. The presentation shows an overview of this research. The findings are relevant for global standardization procedures and to improve the overall safety in chemistry and technics.</abstract>

    <title language="eng">Investigation of Realistic Fire Scenarios Involving Cryogenic Storage Tanks</title>
    <abstract language="eng">The number of vehicles using or transporting cryogenic fuels such as Liquefied Hydrogen (LH2) or Liquefied Natural Gas (LNG) increases fast in the land transportation sector. Does this also entail new risks for instance from a BLEVE? A key to answer this question is to research representative fires by its characterization and its effect on the insulation. At BAM’s technical test side in Germany, a test series was started to answer this question among others. This paper presents results on a pool fire under a colorimeter, that simulates a tank. The investigation points out, that the full fire characterization approach allows to represent the fire. The findings are relevant for the investigation of a representative design fire that is applicable for the approval and improvement of tanks as well as to research accident scenarios and their consequences.</abstract>

    <abstract language="deu">Die Bundesanstalt für Materialforschung und -prüfung (BAM) forscht und prüft für Sicherheit in Technik und Chemie an drei Standorten in Berlin, sowie auf dem Testgelände Technische Sicherheit in Horstwalde in Brandenburg. Hier haben wir weitreichende Möglichkeiten, Großversuche im Realmaßstab durchzuführen. Besonderes Augenmerk richten wir heute auf das Reallabor Wasserstofftankstelle. Diese voll digitalisierte technische Anlage, die die Wertschöpfungskette von Wasserstoff abbildet, wurde gerade eröffnet und steht nun Partnern aus Industrie und Forschung sowie kleinen mittelständischen Unternehmen oder Start-Ups zum gemeinsamen Forschen und Erproben neuer Technologie zur Verfügung. Ihre Besonderheiten umfassen z.B. eine umfassende Prozessüberwachung nach Industrie 4.0, die dafür nötige IT/OT Infrastruktur, Digitale Zwillinge auf verschiedenen Ebenen, großflächige Aufstellung und baulicher Schutz, Gas-Probenahmestellen auf dem Weg durch die Anlage und H2-Sensornetzwerke zur frühzeitigen Erfassung und Ortung von Leckagen.</abstract>

    <title language="eng">Testing of vacuum insulation panels for liquid hydrogen storage tanks</title>
    <abstract language="eng">Vacuum insulation panel (VIP) based insulation could present an alternative to the common double walled vacuum insulation for large liquefied Hydrogen (LH2) storage tanks. In this paper a brief introduction on VIPs and the envisioned design of VIP-based LH2-tank insulation is given. The design of a flat plate boil-off calorimeter for the testing of the insulation concept is shown, with regard to thermal design, mechanical design and instrumentation. Finally, an overview over the particular challenges for modelling VIP-based insulation and the proposed testing to be performed on the test rig is presented.</abstract>

    <title language="eng">Comparative life cycle assessment of vacuum insulation panel core materials for liquid hydrogen storage tanks – glass bubbles compared to conventional core materials</title>
    <abstract language="eng">The environmental performance of insulation materials for liquid hydrogen storage tank application is important to the development of sustainable supply chains. As new materials keep evolving, there is a need to assess their environmental impact. Therefore, this study investigates the environmental sustainability and circularity of cryogenic insulation concepts, namely vacuum insulation panels (VIPs), exclusively focussing on their core materials. Employing a cradle-to-grave life cycle assessment model, the VIP core materials are investigated with a special focus on glass bubbles. Based on the results, the global warming potential of the considered core materials, namely, glass bubbles, silica aerogel, fumed silica, expanded perlite, glass fibre, and polyurethane foam is 9.21∗10^−2, 7.00, 2.50∗10^−1, 3.63∗10^−2, 6.68∗10^−2, and 1.88 kg CO2 eq. per functional unit, respectively. In general, silica aerogel and polyurethane foam are the least environmentally friendly materials, while the most sustainable is expanded perlite, followed by glass fibre, glass bubbles, and fumed silica.</abstract>
