To ensure the safe and efficient operation of the liquid hydrogen (LH2) infrastructure, it is crucial to understand the thermodynamic processes in LH2 tanks. All LH2 tanks, both stationary tanks and tank trailers, experience pressurization due to heat inleak through their thermal insulation. The self pressurization rate over time is important for safe operation, but the complex thermodynamic...
Liquid hydrogen storage is accompanied by boil-off losses as heat leak penetrates the tank. However, these losses are also affected by tank operational scenarios which have been relatively unconsidered in the literature. To address this need, a reduced-order model capable of analyzing different operational scenarios was developed. Using this model, the present study investigates the effects of...
The self-pressurization behaviour of a cryogenic liquid due to the inevitable heat inleak into a closed cryogenic storage system is of great importance for the design of such a storage vessel. In recent years, the resurgence of cryogenic liquid hydrogen as a fuel in future sustainable transportation and logistics sparked new interest in this field of research. The cryogenic fuel tank...
Hydrogen is increasingly recognized as a cornerstone of the transition to sustainable energy systems. Storing hydrogen in liquefied form (LH₂) is particularly advantageous due to its relatively high energy density and scalability for storage and transport. However, managing boil-off rates (BOR) during storage and transportation remains a significant challenge. Hydrogen boil-off leads to safety...
Developing advanced infrastructure components, including Liquid Hydrogen (LH2) storage tank, is crucial to LH2 supply chain pathway development for maritime & international trade applications. Because of extreme cryogenic temperatures of LH2 at 20 K, the storage tank needs to be well insulated to minimize the boil off rate (BOR). While high vacuum insulation technology is commonly used for LH2...
In 2023, the global LNG industry's operational mandate reached a record high of 404 Million Metric Tonnes (MMT). In contrast, the long-term sustainability of LNG as a primary fuel is declining, particularly in view of the carbon-neutral objectives established for 2050. The proposed decarbonisation objectives for 2050, would render many re-gasification and liquefaction facilities at numerous...
Liquid hydrogen (LH2) storage offers significant advantages in storage density and operating pressure, showing promising prospects for mobile applications. However, experimental studies on tank internal thermodynamics typically involve smaller tank sizes and primarily focus on vertical tanks. Detailed studies of horizontal tanks, which are more suitable for vehicle applications, are limited,...
