H2 Storage System Successfully Scaled up

Since September 2023, AMBARtec has been testing its 7.5 kg H2 storage system in full operation with hydrogen. The aim was also to optimise the plant control and find the best system configuration in terms of energy balance. Maximum energy efficiency: AMBARtec’s storage system + SOECThe energy balance analysis shows...

Saving Florida’s Blighted Corals

Florida’s coral reefs are critical to the state’s economy. They protect beaches and play a vital role in supporting thriving fisheries. However, time may be running out to witness some types of live coral in the Florida Keys. A severe heat wave in the summer of 2023 killed many species, and...

CEC to Award Two Prestigious Scholarships at 2025 Conference

The Cryogenic Engineering Conference (CEC) will award two distinguished scholarships at the upcoming 2025 CEC/ICMC: the Donna Jung Memorial Scholarship Award and the Klaus and Jean Timmerhaus Scholarship Award. These awards are part of the CEC’s ongoing efforts to encourage the next generation of engineers and scientists in the field...

Beckman Institute Labs Bridge Advanced Imaging and Alzheimer’s Research

The Beckman Institute for Advanced Science and Technology at the University of Illinois Urbana-Champaign has embarked on a life-changing research project to advance the early detection and diagnosis of Alzheimer’s disease. With the support of a $3 million grant from the US National Institute on Aging of the National Institutes...

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...

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...

Resistance to embrittlement at low temperatures

Could anyone advise me about resistance to embrittlement at low temperatures for the alloys in subject, i.e. does the CF10M perform like the CF8M in the same cryogenic service (-215F)? Amara Maafi Amara.Maafi@bg-group.com

Need help with temperature dependent model

I am a fourth-year student at New Zealand University. My name is Xu Ke. I have a project to generate a temperature dependent model for inductor, capacitor and diode by using PLECS. PLECS is software which acts as a toolbox for MATLAB. In my models, the temperature is very low,...

In what form is water available in LN2?

Does anybody know in what form water is available in LN2? There probably is a block of ice in the bottom of the tank. But as water comes in many shapes, I can imagine snow or crystals floating free in the LN2. When water is available in LN2, could small...

Separating gases using cryogenics

We are looking for some consulting engineers who understand how to separate gases using cryogenics. We have a new process which takes biomass and converts it to 5 gases and we need to separate these gases into their pure forms. Thanks for your help. Malcolm Draper Energy Research Group LLC...
