An ice harvesting storage vessel (10) having an outer structural shell and insulated to maintain a frozen environment for ice filled containers (11) in a subterranean environment. The intake vent damper (16) opens during natural climatic sub-zero temperatures via temperature sensors (24,25) allowing cold air to flow into said vessel. The exhaust vent damper (17) operates in conjunction with the intake damper to allow warmer internal air to exit the vessel. Thermal sensors in conjunction with a thermostat control module close the vent dampers when external atmospheric temperatures exceed internal vessel temperatures. In addition, refrigerant line (22,23) circulate an antifreeze fluid via pump (30) throughout the vessel transferring cold temperatures to a heat transfer medium or antifreeze fluid for transfer to an adjacent facility or point of use.
