1.0 Introduction to Cryogenic Fluid Management (CFM)

In September of 2022 I taught a short course on cryogenic fluid management (CFM) at NASA's Thermal and Fluid Analysis Workshop. The course covered analysis and design of liquid hydrogen systems as well as other cryogenic fluids used in power and propulsion applications.

Although the target audience was aerospace engineers and scientists, most of the topics are directly applicable to liquid hydrogen systems in general (e.g., energy, transportation, marine, etc.). As such, the course content can be used as a resource for the development of any liquid hydrogen system.

This first video is a short introduction. Subsequent videos posted over the coming weeks will cover the other topics presented during the course. My hope is that these edited clips will be easier to digest - and later revisit as needed - rather than posting the full ~3 hour video.

The reference report used to present the course topics can be accessed on the Training page at Any feedback on this material, or future topics of interest, are appreciated and can be emailed to:

The example calculations for these topics are discussed in the next post.

Matt Moran is the Managing Member at Moran Innovation LLC, and previous Managing Partner at Isotherm Energy. He's been developing power and propulsion systems for more than 40 years; and first-of-a-kind liquid, slush and gaseous hydrogen systems since the mid-1980s. Matt was also the Sector Manager for Energy & Materials in his last position at NASA where he worked for 31 years. He's been a cofounder in seven technology based start-ups; and provided R&D and engineering support to hundreds of organizations. Matt has three patents and more than 50 publications including the Cryogenic Fluid Management report series. More about him can be found here.
