Sonatrach and Coolergy in Talks to Produce Blue LH2 for Global Supply

Sonatrach, Algeria’s state-owned oil and gas leader, is making strides in the renewable energy sector through a promising discussion with Coolergy S.L., a Spanish engineering company specializing in liquid hydrogen solutions. The meeting, involving Sonatrach’s director for green and renewable energy, Youcef Khanafar, and Coolergy’s CEO, Kirill Lyats, was held...

Webb Maps Full Picture of How Phoenix Galaxy Cluster Forms Stars

Researchers using NASA’s James Webb Space Telescope have finally solved the mystery of how a massive galaxy cluster is forming stars at such a high rate. The confirmation from Webb builds on more than a decade of studies using NASA’s Chandra X-ray Observatory and Hubble Space Telescope, as well as...

Innovative Liquid Hydrogen Tank Tech Gets ABS AIP

In a development that validates large-scale liquid hydrogen tank technology for shipping, HD Korea Shipbuilding & Offshore Engineering (HD KSOE) has received approval in principle (AIP) from ABS for a tank design that enables large-scale hydrogen transportation and storage. ABS completed design reviews based on class and statutory requirements. “Hydrogen is...

NASA’s NICER Continues Science Operations Post Repair

NASA crew aboard the International Space Station installed patches to the agency’s NICER (Neutron star Interior Composition Explorer) mission during a spacewalk on Jan. 16. NICER, an X-ray telescope perched near the station’s starboard solar array, resumed science operations later the same day. The patches cover areas of NICER’s thermal...

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...

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...
