Hydrogen is increasingly recognized as a clean energy carrier with significant potential for decarbonizing hard-to-abate sectors. In hydrogen transfer systems, liquid hydrogen (LH₂) is preferred over its gaseous form due to its higher density (i.e. 70 kg/m³ compared to 0.083 kg/m³ at atmospheric pressure). Generally, centrifugal pumps are a suitable choice due to the operating conditions...

This study evaluates the performance of a superconducting linear-actuator demonstrator that is based on a ReBCO layer-wound solenoid. The solenoid geometry was chosen in view of ease of manufacturing and scalability. Compared to a similarly-sized copper actuator with the same power consumption, the demonstrator is designed to generate a force that is 2 orders of magnitude greater. It comprises...

The rapid expansion of cryogenic technologies, such as quantum computing, necessitates robust, scalable, and high-throughput cryogenic testing infrastructure. As these systems transition from prototypes to commercial products, a significant bottleneck emerges in the need for efficient, production-level testing of numerous components at low temperatures. While many cryogenic systems are...

Cryocoolers are increasingly favored over baths or forced-flow cooling providing heat removal and thermal stability for magnets made of High Temperature Superconductor (HTS). Efficient heat transfer between magnet and cryocooler is crucial to the operation of such a system. Compared to conventional thermal buses, which are typically made of solid materials such as high-purity copper braids,...

The cryogenic re-liquefaction of Boil-Off Gas (BOG) is a critical step in LNG infrastructure, where methane vaporized due to unavoidable heat ingress must be recovered to mitigate energy losses and reduce greenhouse gas emissions. Methane's high global warming potential—over 80 times greater than that of CO₂ over a 20-year horizon—makes its release particularly concerning from both...

Regenerators are an integral part of regenerative-type cryocoolers, such as pulse tube, Gifford-McMahon cryocoolers, etc. The main function of a regenerator is to store and release heat during the cyclic operation of cryocoolers. The performance of the regenerator directly influences the performance of the cryocooler. Therefore, regenerators should be designed and optimised carefully. The...

The regasification of cryogenic liquids, such as liquefied natural gas (LNG), liquid hydrogen (LH₂), and industrial gases like nitrogen and oxygen, offers an unique opportunity for energy recovery during their transition from liquid to gas and subsequent gas heating to ambient temperature. Liquefaction of gases for their transport and storage occurs at extremely low temperatures and requires...

In macroscopic solid-state thermal diodes (MSTDs), spatial and temperature asymmetry arises from combining two materials whose thermal conductivities vary differently with temperature [1]. These devices offer strong potential for passive directional heat control in cryogenic environments. However, current state-of-the-art MSTDs exhibit rectification factors (RF) that remain too low for...

No-insulation (NI) high-temperature superconducting (HTS) coils offer improved thermal stability and self-protection compared to conventional insulated coils. Despite these advantages, quenches can still occur. The inherent current-sharing property of NI coils allows for coil design with potential recovery after a quench, provided the current redistribution is well characterized.
