PURPOSE: To provide simple, efficient and compact gas supply facilities usable for backup of main facilities for supplying gas under high pressure and capable of readily supplying particularly supercritical pressure gas under high pressure. CONSTITUTION: Facilities include a heat insulating reservoir 1 for storing gas at least partially liquefied under high pressure, a pipe passage 2 having an evaporator 3 for supplying gas to a user plant A, a first cold holding circuit 4 having a first heat exchanger 6 adapted to contact a fluid in a valve 5 and the first reservoir 1 in heat exchanging relation and a second pressure holding circuit 8 having a second heat exchanger 9 and a valve 10. These are used mainly as backup facilities for a main gas producing source 30.
