How Hydrogen Fuel Cells and Combustion Could Revolutionize Racing

Hydrogen power is gradually making its mark on the motorsport scene. This year, we have already witnessed hydrogen race cars competing in the Fuji 24 Hours, hillclimbs, and the Dakar Rally. Looking ahead to 2025, the world’s first hydrogen championship, Extreme H, will debut, and by 2027, hydrogen prototypes are...

En Route Toward the First German Quantum Computer

Fraunhofer IPMS is collaborating on the development of an integrated German quantum computer based on superconducting quantum chips. Together with 24 German research institutions and companies, under the coordination of Forschungszentrum (FZ) Jülich, Fraunhofer IPMS is working on this quantum computer with the goal of improving error rates. At the halfway...

Lightweight Supramolecular Material for Compressed Hydrogen Storage

A team of chemists from the University of Hong Kong, Northwestern University, and Duke University has developed a supramolecular material capable of compressing hydrogen for storage without being too heavy. Their study, published in Nature Chemistry, demonstrates the use of porous organic crystals for hydrogen storage. Hydrogen has long been...

Indian Student to Research Liquid Hydrogen with Monash University

A Ph.D. student from India is conducting groundbreaking research with Monash University’s Department of Civil Engineering after being selected as the recipient of the prestigious Australian government-funded Maitri Scholars Program. Chennai native Rohith Prakash will focus on advancing the safe transport and storage of liquid hydrogen, with a particular emphasis on...

Rising Helium Demand Set to Double by 2035

A new report from IDTechEx suggests that global helium demand is set to double by 2035, driven by the wide-ranging applications of this vital element. Helium, a finite yet critical resource, is indispensable across multiple industries. From medical imaging to semiconductor manufacturing, helium’s unique properties—such as high thermal conductivity, chemical...

Cryogenic Therapy Puts the Freeze on Esophageal Cancer

Patients with esophageal tumors often experience malignant dysphagia, or difficulty swallowing due to an obstruction, complicating their treatment and preventing them from eating normally. The Advanced Center for Therapeutic Endoscopy at WVU Medicine J.W. Ruby Memorial Hospital is the first in West Virginia to offer an innovative solution to this...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Liquefied Natural Gas

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) 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...
