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,...

Two-Phase Flows

Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...

Supercritical Fluids

A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...

Brayton Cycle

The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
