This patent describes a method for generating power from LNG and storing energy. It comprises: providing a source of LNG at a temperature of about {minus}250{degrees} F. or lower, increasing the pressure of the LNG to at least about 400 psia, creating a reservoir of carbon dioxide liquid at about the triple point thereof which reservoir contains a substantial amount of solid carbon dioxide, vaporizing the LNG to natural gas by removing heat from CO{sub 2} at about the triple point temperature, heating the high pressure natural gas, expanding the heated natural gas to create rotary power, and employing the carbon dioxide in the reservoir in a useful manner which results in the creation of CO{sub 2} vapor that is subsequently reliquefied.
