  • Cryogenic Tank - an overview | ScienceDirect

    The boil-off rate of H 2 is typically 0.4%/day for 50 m 3 tanks, 0.2% for 100 m 3 tanks and 0.06% for 20 000 m 3 tanks (using double-walled vacuum-insulated spherical Dewars). Loss of hydrogen due to boil-off is a problem, although recent work indicates that for the most recent tank designs, venting occurs only in the case of …
