Energy Storage & Microgrids

Largest Liquid Hydrogen Dewar Zero Boil-off and Densification

Description: Design of the largest liquid hydrogen dewar tank in history that will hold 1.4 million gallons of liquid hydrogen. System eliminates boil-off and provides densification capability with an integrated cryogenic refrigeration unit and internal heat exchanger. Storage capacity is 50% greater than the current record holder that supported space shuttle launches for over 39 years. Performed under subcontract to Sierra Lobo and BRPH.

Customer: NASA Kennedy Space Center (KSC)

Status: Design completed and accepted by NASA. Construction started in 2019.
