Green hydrogen is the talk of the town these days, but how useful are all those colors of hydrogen that get referenced as a shorthand? It seems to me that we are better off adopting...
Valves are used all along the industrial gas and cryogenic gas supply chains – for production and transportation, for trans-fill operations into storage containers, and in end-use customer piping circuits.

Parts 1 and 2 of this this primer discuss three common types of flow isolation and control valves used in the cryogenic industry. Part 1, below, will focus on globe and gate valves, their basic...
Imagine that you are filling a cryogenic tank sitting on weight scales. You fill it to the proper fill density from a tank supplying very cold zero psi liquid and record the weight. You then...
Last month in part one of this article, we discussed the makeup of carbon dioxide (CO2) and the four phases or states of matter for CO2 that we typically deal with (solid, liquid, vapor, and supercritical...
The carbon dioxide (CO2) molecule is composed of one carbon atom covalently bonded to two oxygen atoms. At less than 0.04%, carbon dioxide is still the fourth most common gas present in the earth’s atmosphere....
There are a wide variety of hydrogen compressor and pump technologies in use today. Types of compressors include diaphragm, reciprocating piston, and centrifugal. Pumps for hydrogen applications consist of various kinds of positive displacement systems. Each compressor and...
Saturation is an important, yet often misunderstood concept in the cryogenic industry. A basic understanding of the term “saturation” is necessary to harness and exploit the benefits of using cryogenic liquids in our specific industries...
