Scaling Up Cryogenics for Quantum Computing

As we enter 2024, the field of quantum computing continues to develop rapidly. Accessibility to quantum processing and the scaling of systems are key factors in the growing industry. Cloud-based services offer one potential access route to quantum processing, but systems are also being deployed for customers to host on-premises....

‘First-Ever’ Cryogenic Refueling space Mission Announced

Two space infrastructure specialists, Space Machines Company and Spaceium, have joined forces to embark on what they believe to be the first-ever cryogenic refueling space mission in space in 2025. Under terms of a signed agreement, Canada’s Spaceium will integrate its cryogenic storage technology into Space Machine’s platform. Spaceium will then...

Air Products to Build Europe’s Largest Blue Hydrogen Plant

Air Products announced it will build, own and operate a state-of-the-art carbon capture and carbon dioxide (CO2) treatment facility at its existing hydrogen production plant in Rotterdam, the Netherlands. The facility is expected to be on-stream in 2026, and the resulting “blue” hydrogen product to serve ExxonMobil’s (Esso) Rotterdam refinery...

Maddox Industrial Group Announces Expansion to Gulf Coast

Maddox Industrial Group (MIG), a leader in delivering specialized industrial solutions to the air separation, energy, refining, petrochemical, wastewater, and other industries, has announced its strategic expansion into the Gulf Coast region. This growth is in collaboration with partner, Metalforms LLC (Metalforms), an industrial fabrication, services, and heat transfer solutions...

Can LH2 Preserve Our Last Clean Continent?

Antarctica is vital for cold research, from understanding our fragile climate to tracking local fauna. Energy is critical to this research as it supports expeditions and heating bases. Reliance on diesel import is leaving a dark legacy on the continent, as the buildup of black carbon is causing accelerated rates...

Commonwealth Fusion Cryo Team’s Just-in-Time Engineering

High temperature superconducting (HTS) tapes, which have emerged over the last decade, are enablers for new technologies. Specifically, high temperature superconducting magnets to enable commercial fusion energy are arguably the most tantalizing and potentially impactful. Fusion energy would be a long-envisioned source of firm, safe, carbon-free electricity whose successful development...

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...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...
