Abstract
A hydrogen-based propulsion system is provided for storing hydrogen feed gas which evaporates over time from a storage vessel containing liquid hydrogen as a fuel. In particular, this system enables the evaporated hydrogen feed gas to be stored for later use in the propulsion unit and also provides a system for enabling the stored hydrogen gas to be cooled by evaporated hydrogen feed gas in transit to the propulsion unit.
