1. A method of gasification of an environment of interest having the characteristic of a low concentration of gas, comprising the steps of:

  • preparing a powdered gas hydrate;

    mixing the hydrate with powdered ice which has a low concentration of a dissolved gas;

    pulverizing the mixture of the hydrate and the ice into small particles;

    encapsulating the mixture of the hydrate and the ice within a pressure vessel;

    applying a high pressure to the mixture;

    warming the pressure vessel and its contents to provide an aqueous suspension of the hydrate within liquid water formed from the ice upon warming;

    providing a conduit in communication with the pressure vessel and a catheter, the catheter having one or more high resistance exit ports so that sufficient pressure is maintained for continued stabilization of the hydrate prior to emerging from the catheter; and

    injecting the suspension of the particles into the environment of interest at a rate which permits mixing of the hydrate with the environment before decomposition of the gas hydrate or bubble coalescence can occur.
