Air Liquide Inaugurates Liquid Hydrogen Plant in Nevada

Oxygen, nitrogen and hydrogen are essential small molecules for life, matter and energy. They embody Air Liquide’s scientific territory and have been at the core of the company’s activities since its creation in 1902. A world leader in gases, technologies and services for industry and health, Air Liquide’s ambition is...

Artemis I Mission Availability

Editor: Rachel Kraft Image: CREDIT: NASA/KIM SHIFLETT Artemis I WDR (6-20-22) Update: ICPS Propellant Loading Begins The launch control team is filling the Space Launch System’s interim cryogenic propulsion stage (ICPS) with liquid hydrogen (LH2) followed by liquid oxygen (LOX) loading. The core stage LH2 and LOX tanks, meanwhile, are being...

Hydrogen Infrastructure Challenges Rival Aircraft Tech Hurdles

Of all the various renewable energy sources under development, hydrogen represents the so-called “holy grail” in the effort to eliminate carbon emissions from future aircraft, say many scientists. But while the technology exists today to build a hydrogen-powered aircraft, prompting several startup enterprises to develop fuel-cell-based vehicles for the burgeoning...

Airbus Facility to Develop Cryogenic Hydrogen Tank System for Future Planes

Airbus has announced that it is launching a facility based in the United Kingdom, where a new cryogenic hydrogen tank will be developed for its next generation of aircraft. The UK facility in Filton, Bristol has already started working on the technology’s development. The company recently released an Airbus news statement sharing that...

Taking Charge: Predicting and Improving Energy Storage Materials

 Perfection is a problem when it comes to how computers model materials for energy applications. Although a typical model assumes materials are perfect, in reality they have flaws at their interfaces and boundaries. At Lawrence Livermore National Laboratory, researchers simulate ion transport for ways to predict and improve materials for energy...

QED-C® Announces Four Projects Designed to Advance Cryogenics for Quantum Information Science and Technology

The Quantum Economic Development Consortium (QED-C), managed by SRI International, in strategic partnership with the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST), today announced a $2.3 million research program to advance cryogenic technologies that will enable innovation in quantum information science and technology (QIST). The program aims to...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

You are encouraged to read Cryo Central’s History...

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...
