Removing the Quantum Barrier to Sustainable LH2 Fuel in Aviation: A Mechanistic, Process, and Environmental Life Cycle Assessment of the Ortho-Para Conversion in Liquefaction
… is challenged by the high energy cost and boil-off losses associated with the exothermic ortho-to-para hydrogen conversion (OPC). A fundamental trade-off exists between the energy invested during liquefaction to achieve a high para-H2 content for storage stability and the practicality of …

The Role of Hydrogen Fuel in Hard-to-Decarbonise Modes of Transport: An Energy Systems Perspective
… and (4) the influence of weather induced boil-off on LH2 ship design. Methods such as energy systems analysis, thermodynamic concepts and numerical methods (e.g., Monte Carlo simulations) are utilised to construct models of LH2 fuelled aircraft and ships. These models are applied to …

Investigation of pressure-tube and calandria-tube deformation following a single channel blockage event in ACR-700
… and full pressure, resulting in rapid coolant boil-off and fuel overheating. Melting of the Zircaloy (Zry) components of the fuel bundle (cladding, end plates and end caps) can occur, with relocation of some molten material to the bottom of the PT. The hot spot caused by the molten Zry/PT …

Maritime Vehicle Routing under Uncertainty: Liquefied Natural Gas Shipping and Offshore Pipeline Damage Assessment Problems
… ship construction technology advances and random boil-off gas (BOG) generation. This is formulated as a two-stage stochastic mixed integer program. In the initial stage, a single production-inventory plan and routing schedule is determined before the realization of the random BOG generation. For …

Droplet growth kinetics on superhydrophobic surfaces and future work on combating cryogenic surface contamination
… require high capacity cryocoolers for zero boil-off (ZBO) systems. Due to parasitic heat loads, cryocoolers have low efficiency, making approaches to limiting these loads highly desired. Water cryodepositing onto low-emissivity cryogenic surfaces results in high parasitic radiative loads. In …

High-Resolution Experimental Measurements and Mechanistic Modelling of Saturated Cryogenic Pool Boiling Heat Transfer
… e.g., a fuel depot placed in orbit. The low boiling point of cryogenic fuels (hydrogen, methane, oxygen) makes them prone to boil when transferred through superheated pipes, or simply stored in fuel tanks, resulting in the presence of two-phase mixture. Boil-off gas can lead to pressurization …
