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,...

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

Air Separation and Liquefaction

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...

Power usage: cryogenic systems vs. regular refrigerators

A recent project highlighted to me that closed cycle cryogenic cooling systems use far more electrical power to reduce temperatures by a few watts than regular refrigerators. I am sure it must be something to do with the extra difficulty of removing the heat from the liquid nitrogen or similar...

Redundancy strategies for mechanical -80C freezers

I was wondering what kind of redundancy strategies are people using for their mechanical -80C freezers? I am aware of the following. Please add if you are doing something different. 1) 1 Backup freezer for every 10 freezers – Empty and maintained at -80C at all times 2) Backup C02...

Method to move components in a cryogenic environment

Does anyone know of a method with which to reliably move components in a cryogenic environment? We are interested in moving detectors in a cryogenically cooled (2K) vacuum chamber, which is contained within a larger cryostat/isolation vacuum with thermal shields. As the desired horizontal or vertical displacement is between 10...
