摘要

A conditioning and loading apparatus and method are disclosed for gas storage at cryogenic temperature and supercritical pressure. The apparatus is self-contained and portable and includes first and second precooling stages utilizing heat exchange with vented system fluids to cool the gas received by the apparatus at supercritical pressure. A third cooling stage includes heat exchange in a liquid nitrogen bath before loading of the gas into a container.
