Getting Started with Cool Fuels: Liquefied hydrogen and natural gas (Digital Files and Recording)

Liquefied hydrogen and natural gas fuels are seeing increased interest due to low carbon content and high energy per weight. However, the cryogenic and flammable nature of these liquid fuels adds considerable difficulty for even seasoned experimentalists. This introductory course covers the basics of project startup with liquefied hydrogen or natural gas including fluid specific information on: 1) Thermophysical properties, 2) Liquefaction and Storage, and 3) Safety Standards and Applications. Participants will leave having completed basic calculations on thermophysical properties, examples for constructing cryogenic test equipment, and processes for developing safety plans.

Jacob Leachman is an Associate Professor in the School of Mechanical and Materials Engineering at Washington State University (WSU). He initiated the Hydrogen Properties for Energy Research (HYPER) laboratory at WSU in 2010 to advance cryogenic and/or hydrogen systems. To this day the HYPER laboratory remains the only US academic laboratory focusing on cryogenic hydrogen. He earned a B.S. degree in Mechanical Engineering in 2005 and a M.S. degree in 2007 from the University of Idaho. His master’s thesis has been adopted as the foundation for hydrogen fueling standards and custody exchange, in addition to winning the Western Association of Graduate Schools Distinguished Thesis Award for 2008. He completed his Ph.D. in the Cryogenic Engineering Laboratory at the University of Wisconsin-Madison in 2010 under the advice of John Pfotenhauer and Greg Nellis.

He is the lead author of the reference texts “Thermodynamic Properties of Cryogenic Fluids: 2nd Edition” and “Cool Fuel: The Science and Engineering of Liquid Hydrogen” which is in development. In 2018 he received the Roger W. Boom Award from the Cryogenic Society of America. In 2021 he mentored the NASA Big Ideas Challenge winning team by solving the problem of lunar dust mitigation with liquid nitrogen sprays.
