Cryogenic Liquid Hydrogen (LH2) Vessels
Cryogenic liquid hydrogen (LH2) vessels are specialized pressure containers designed to store liquid hydrogen at its boiling point of -423°F (-253°C). These vessels require exceptional insulation systems and materials specifically selected for hydrogen compatibility to ensure safe containment of this extremely cold, flammable cryogen.
Why are Cryogenic Liquid Hydrogen (LH2) Vessels Needed?
Liquid hydrogen vessels are increasingly critical for the emerging hydrogen economy, aerospace propulsion, and industrial applications. LH2 provides the highest energy density per unit mass of any fuel, making it essential for space launch vehicles and fuel cell transportation applications where weight is critical.

Cryogenic Liquid Hydrogen (LH2) Vessels Frequently Asked Questions (FAQs)
What special considerations apply to liquid hydrogen vessels?
LH2 vessels require materials resistant to hydrogen embrittlement, excellent insulation to minimize boil-off, and safety systems addressing hydrogen’s wide flammability range (4-75% in air). Ortho-para hydrogen conversion during storage generates heat that must be managed through proper catalyst design or controlled venting.
How do you address hydrogen embrittlement concerns?
We select materials proven compatible with hydrogen service including austenitic stainless steels (304L, 316L) and aluminum alloys that resist hydrogen embrittlement. All welds and heat-affected zones are carefully controlled to maintain material properties. NASA and industry hydrogen compatibility data guides our material selection.
What safety systems are included for hydrogen service?
LH2 vessels include multiple safety systems including pressure relief devices sized for fire exposure, leak detection systems, emergency venting, and proper electrical classification for hydrogen atmospheres. Vessels are designed to codes including ASME, CGA, and NFPA 2 (Hydrogen Technologies Code).
