1. An apparatus for compressing and storing an oxygen-enriched gas, comprising;

  • an oxygen concentrator product tank having oxygen-enriched gas therein, wherein said oxygen-enriched gas contains at least about 70% oxygen by volume;

    a piston compressor operatively connected to said oxygen concentrator product tank to receive prioritized oxygen-enriched gas therefrom;

    said compressor operated by a power source other than oxygen-enriched gas from said concentrator product tank and being capable of compressing said oxygen-enriched gas to a high pressure; and

    a high-pressure storage container for portable storage of said high-pressure oxygen-enriched gas.
