Ortho-H2 refueling for extended cryogenic pressure vessel dormancy
Patent
·
OSTI ID:1600288
A cryogenic hydrogen storage system reduces hydrogen loss by providing an initial supply of hydrogen wherein the initial hydrogen has an initial para/ortho hydrogen ratio. The initial hydrogen having an initial para/ortho hydrogen ratio is adjusted to produce final hydrogen having a final para/ortho hydrogen ratio with a greater amount of ortho hydrogen, The cryogenic hydrogen storage system is refueled with the final hydrogen having a final para/ortho hydrogen ratio with a greater amount of ortho hydrogen.
