CB&I and Shell Unveil First Commercial-Scale Liquid Hydrogen Storage Tank Design

At NASA’s Marshall Space Flight Center in Huntsville, Alabama, a major step toward global hydrogen trade has quietly taken shape. CB&I, in partnership with Shell, GenH2, and the University of Houston, recently unveiled a first-of-its-kind concept for affordable, commercial-scale liquid hydrogen (LH2) storage—designed to support international import and export operations....

Hidrogenii Commissions 15 Ton Per Day Hydrogen Liquefaction Plant in Louisiana

Hidrogenii, the joint venture between Plug Power Inc. and Olin Corporation, has announced the commissioning of its 15 metric-ton-per-day (TPD) hydrogen liquefaction plant in St. Gabriel, Louisiana. Among the largest electrolytic hydrogen liquefaction facilities in North America, the site marks a major milestone in strengthening the regional hydrogen supply chain...

New AI Tool Set to Speed Quest for Advanced Superconductors

Using artificial intelligence shortens the time to identify complex quantum phases in materials from months to minutes, finds a new study published in Newton. The breakthrough could significantly speed up research into quantum materials, particularly low-dimensional superconductors. The study was led by theorists at Emory University and experimentalists at Yale...

A Simple Way to Control Superconductivity

Scientists from the RIKEN Center for Emergent Matter Science (CEMS) and collaborators have discovered a groundbreaking way to control superconductivity—an essential phenomenon for developing more energy-efficient technologies and quantum computing—by simply twisting atomically thin layers within a layered device. By adjusting the twist angle, they were able to finely tune...

Bluefors Opens Lab Facility in Chicago

Bluefors, the world leading manufacturer of cryogenic measurement systems for quantum technology, announced the opening of a new lab facility in Chicago. The facility will be used to provide the Bluefors Lab service, bringing the service into the United States for the first time. Bluefors Lab provides startups, research groups,...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

In search of a calculation for designing a cryostat

I am a final year physics student at the University of Birmingham, and as part of a group I am currently designing a cryostat. One of the calculations I need to make (very soon!) is how much heat will be conducted down the walls. All information I have found so...

Safety of ethylene glycol and pressurized oxygen

We are reviewing the product design of liquid filled differential level gauges and want to insure that they meet the industry requirements. The former license owner had authorized that a fill fluid of ethylene glycol (68%) and distilled water (32%) could be used for oxygen service up to 500 psi....
