Magneto-chemistry of catalysts for liquid hydrogen production and storage

" and "site-specific" experimental methods. The fourth section presents current industrial challenges, highlighting the importance of catalytic steps, and their modeling, in hydrogen liquefaction and storage. The irreversible nature of hydrogen flow through porous catalysts in liquefiers is discussed, and an original short-term hydrogen reservoir model is presented. It is based on the cryogenic, cybernetic, hydrodynamic and catalytic properties of a barrage system of successive microporous catalysts. Finally, break-even times for storage processes are introduced and discussed.
