“…The thermal conductivity of the wall should be as low as possible. For the reader's benefit, it is worth noting that much literature covering insulations is in tandem with the hydrogen storage tanks and are available for hydrogen applications [56,69,70]. It concludes that the preference must be towards the low-density foam and multi-layer insulation (MLI) under vacuum, as aerogels are still too fragile for now.…”

“…A numerical comparison of four combinations of insulation methods based on SOFI, MLI and vapor cooled shield (VCS) is available in the literature [69] where the latter is an active insulation method. It asserts that, for safety reasons, SOFI should always serve at least as a guarantee of insulation efficiency in case of vacuum leaks.…”

“…It asserts that, for safety reasons, SOFI should always serve at least as a guarantee of insulation efficiency in case of vacuum leaks. Part of the originality of the approach in this study is the different vacuum degrees considered [69]. However, since this work doesn't focus on aviation, it is hard to draw parallels.…”

The thermal management system architectures proposed for hydrogen-powered propulsion technologies are critically reviewed and assessed. The objectives of this paper are to determine the system-level shortcomings and to recognise the remaining challenges and research questions that need to be sorted out in order to enable this disruptive technology to be utilised by propulsion system manufacturers. Initially, a scientometrics based co-word analysis is conducted to identify the milestones for the literature review as well as to illustrate the connections between relevant ideas by considering the patterns of co-occurrence of words. Then, a historical review of the proposed embodiments and concepts dating back to 1995 is followed. Next, feasible thermal management system architectures are classified into three distinct classes and its components are discussed. These architectures are further extended and adapted for the application of hydrogen-powered fuel cells in aviation. This climaxes with the assessment of the available evidence to verify the reasons why no hydrogen-powered propulsion thermal management system architecture has yet been approved for commercial production. Finally, the remaining research challenges are identified through a systematic examination of the critical areas in thermal management systems for application to hydrogen-powered air vehicles’ engine cooling. The proposed solutions are discussed from weight, cost, complexity, and impact points of view by a system-level assessment of the critical areas in the field.

“…[1][2][3] Hydrogen energy, a sustainable energy source, has great application prospects due to the advantages of rich sources, high utilization rate, wide ranges of uses, and large calorific value per unit mass, and is gradually being used in the fuel cells, transportation, and aerospace applications. [4] However, the actual large-scale promotion of hydrogen energy is constrained by two factors: low-cost production and safe-efficient storage. [2] For hydrogen production, it is currently mainly extracted from fossil fuels, whereas some sustainable green hydrogen production technologies, such as electrolytic hydrogen production, biomass energy, and photocatalytic hydrogen production, have also been developing rapidly in recent years.…”

“…[18] Commonly used passive thermal insulation methods include multilayer insulation (MLI), spray on foam insulation (SOFI), and powder insulation. [4,19,20] MLI achieves a very high thermal insulation performance, and its apparent thermal conductivity can be as low as 10 À6 -10 À5 W (m K) À1 . [21][22][23] The disadvantage of MLI is that it is susceptible to vacuum changes.…”

The efficient storage method of hydrogen energy is a major concern in its practical application. Compared with other hydrogen storage methods, liquid hydrogen (LH2) storage has the advantages of high energy storage density and low storage pressure. However, the temperature of LH2 is significantly lower than room temperature, and heat leakage causes it to evaporate continuously. Thus, an efficient thermal insulation technology is a key to LH2 storage. Herein, based on the traditional multilayer insulation (MLI), a novel insulation system combining hollow glass microspheres (HGMs) that is not sensitive to vacuum with self‐evaporating vapor cooled shield (VCS) that can recover hydrogen cold‐energy is introduced and analyzed. Based on the layer‐by‐layer method, a thermodynamic calculation model is established, and related experimental verification is completed. The results show that the heat leakage of the proposed insulation system is decreased by 45% under high vacuum (10−3 Pa) and 81% under low vacuum (1 Pa) compared with the traditional MLI. The influences of the VCS position, LH2 storage pressure, hot boundary temperature, and vacuum on the thermal insulation performance of the composite thermal insulation system are also analyzed.
