Summary: As human space travel continues to advance, the need for long-term storage of cryogenic propellants becomes crucial, requiring effective cryo-fluid system management. Experimental measurements have shown that using boil-off gases of colder liquid hydrogen to insulate warmer liquid oxygen can reduce static boil-off, providing insights for future usage.

Summary: Hydrogen embrittlement is a well-known phenomenon in high-strength and storage materials, causing subcritical crack growth, fracture initiation, loss in mechanical properties, and catastrophic failure. The fundamental mechanism of hydrogen embrittlement remains unclear, although various mechanisms responsible for crack development, growth, and fracture have been discussed and reported.

Summary: The effect of cryogenic plastic pre-strain on the hydrogen embrittlement of an equimolar FeNiCoCrMn high-entropy alloy was investigated. As the pre-strain increased, the ductility loss under harsh electrochemical hydrogen charging decreased while hydrogen adsorption was promoted. This study provides an effective strategy for achieving high strength and improved hydrogen embrittlement resistance.

Summary: This paper investigates the assessment of leak tightness for pressurized hydrogen storage tanks, specifically for composite laminates. Three different homogenization methods are compared to obtain effective permeation coefficients. The Hashin-Shtrikman bounds method proves to be the most satisfactory. The effect of inter-fiber cracks is also examined to further evaluate leak tightness.

Summary: Mixtures of LiAlH4/FeCl2 and LiBH4/FeCl2 were prepared under cryogenic conditions using ball milling, with the optimal production conditions being milling for 30 minutes at -196 degrees C and 15 Hz oscillation frequency. Hydrogen release in LiAlH4/FeCl2 mixtures starts at around 60 degrees C, while LiBH4/FeCl2 mixtures exhibit dehydrogenation starting at 40 degrees C and finishing at about 300 degrees C. The formation of LiCl is considered the driving force behind the decomposition reactions in these reactive mixtures. Cryogenic ball-milling has a positive effect on production and low-temperature dehydrogenation of the studied samples.

Summary: In this study, carbon fiber composites with significant cryogenic mechanical and hydrogen-barrier properties were prepared by adding polyethylene films to the interlayers of carbon fibers. The cross-linked network structure and toughening effects of polyethylene resulted in higher adhesion force and strength at cryogenic temperatures. The addition of polyethylene films significantly reduced hydrogen permeability, making them suitable for the manufacture of linerless type V hydrogen storage vessels.

Summary: Natural gas distribution systems play a significant role in the US energy consumption, but as the system moves towards decarbonization, understanding the response of existing infrastructure to new operational modes becomes crucial. Opportunistic sampling can reduce data collection costs if it represents the entire asset base. Analysis of a dataset from a large natural gas distribution utility suggests that sampling locations affected by excavation damage can provide representative estimates of key characteristics across the asset base. This sampling approach can help utilities gather necessary data for a safe and reliable transition to a lower-emission system.
