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.

But, tanks in the relevant scale of 40 000 to 200 000 m³ do not exist yet. The upscaling of liquid hydrogen (LH2) storage tanks from the current largest tank of 4700 m³ requires a new concept for thermal insulation. NICOLHy studies novel concepts based on multiple layers of vacuum insulation panels (VIPs). Current LH2 tanks rely on the intactness of a single vacuum layer that covers the whole tank. The multilayered VIP systems offer redundancy and improve manufacturability. The Article describes the progress within the project.

Hydrogen can be well integrated into the electrical energy infrastructure, and its production and use is free of direct GHG emissions. However, tanks are needed for worldwide storage and transportation, which require further development and upscaling. In the EU-funded NICOLHy project, novel insulation concepts based on Vacuum Insulation Panels (VIP) are being investigated. These aim to enable the safe, cost- and energy-efficient storage of large quantities of LH₂. Such large-scale LH₂ storage technology is necessary to build transport and stationary tanks with capacities ranging from 40,000 m³ to more than 200,000 m³ of LH₂, similar to current LNG applications. However, new design concepts are needed, as the technologies currently used for small and medium-sized storage are not suitable for upscaling. The main disadvantages of the current state of the art in terms of upscaling are long production times due to complex process chains, low failure tolerance, and the spherical shape of the tanks, which reduces payload in technical applications by up to 50% compared to other geometries. The novel concept aims to overcome these limitations by being modular, open-form, energy-efficient, time- and cost-efficient in production, operation, and maintenance, safe while being multi-failure tolerant, and suitable for both transport and stationary applications. To achieve these ambitious objectives, experts from all over Europe in the fields of thermodynamics, cryogenics, marine, chemistry, process, and safety engineering are working hand in hand. Within the NICOLHy project, several insulation concepts have been developed and will be benchmarked using a set of key performance indicators aligned with the overall project goals. During the development process, refined and detailed research questions were formulated, which are being addressed through ongoing theoretical and experimental studies. In this context, small to large-scale test rigs are being built to evaluate and quantify insulation materials and concepts. The presentation will showcase the NICOLHy project and its progress. NICOLHy will contribute to accelerating the integration of hydrogen into the European energy economy and industry—supporting the European Green Deal and fostering public trust in both policy and technology.

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.

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.

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 a safety assessment of non-combustible MLI 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.

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.

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.

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.

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.

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.
