Scottish Homes to Be Heated by ‘100% Green’ Hydrogen Gas

Households in Scotland could be using “100% green” hydrogen for cooking and heating if plans for a new world-first gas network are approved. Under the proposal from gas distribution network company SGN, an initial 300 homes in Levenmouth will have access to clean hydrogen within two to three years.

Coldest Material in the Cosmos Could Help Scientists Find Dark Matter Particles

Researchers suggest the coldest material in the universe could reveal the presence of dark matter particles. In a new paper published early May in the journal Physical Review Letters, a group of Spanish scientists suggests magnetometers made using Bose-Einstein Condensates could be used to detect exotic spin-dependent forces. Bose-Einstein Condensates...

Mactac Unveils New Cryogenic Labels

Mactac, a North American adhesives, label and packaging company, has launched new cryogenic labelstocks for temperatures as low as -320º F. Mactac’s cryogenic labelstocks are intended for harsh environment applications where labels must withstand exposure to liquid nitrogen or ultralow temperature freezers, thaw cycles, chemicals and solvents.

Successful Trial Operation of World’s First Hydrogen-Powered Trains Completed

Alstom S.A. of Saint-Ouen, France, has announced that after 530 days and more than 180,000 driven kilometers, the successful trial operation of the world’s first two hydrogen trains was officially completed at the end of February.

VTT to Build Finland’s First Quantum Computer, Seeks to Bolster Finland’s and Europe’s Quantum Competitiveness

VTT Technical Research Center in Espoo, Finland, has launched a project to acquire Finland’s first quantum computer. The first phase of this three-phase project seeks to bolster Finland’s ability to design and build quantum computers and to create a competence base for future applications. The design and construction of the...

Coregas Supporting Coal-to-Hydrogen Project in Australia

A world-first project in Victoria, Australia, that will convert brown coal to hydrogen for export to Japan is being supported by the only Australian-owned industrial gas company, Coregas. The Hydrogen Energy Supply Chain (HESC) project will see liquefied hydrogen produced from Latrobe Valley brown coal transported to Japan for use...

Latest in Defining Cryogenics

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

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...
