A method for regasification of liquefied natural gas (LNG) and an LNG regasification terminal employing said method. An LNG carrier is filled with LNG at an LNG hub and transports the LNG to a receiving terminal. The LNG is offloaded to LNG storage at the receiving terminal. The LNG storage has less storage capacity than the storage capacity of the carrier. The LNG is regasified at a regasification rate at the receiving terminal. The carrier is maintained at the receiving terminal until the carrier is empty, and then returns to the LNG hub to be filled with more LNG. The process is then repeated. The storage capacity of the LNG storage is sufficient to supply LNG for regasifying the LNG at the regasification rate until the carrier returns with additional LNG from the LNG hub. The carrier is the sole source of LNG for the receiving terminal.

A system delivers carbon dioxide to a sequestration facility which may have photosynthetic organisms, such as crops, plants, and trees. The system has a containment structure which houses a volume of liquid or solid carbon dioxide (dry ice). The containment structure has a containment structure inlet and a containment structure outlet. A gas source provides a fluid to the containment structure through the containment structure inlet. Upon entry into the containment structure, the gas or a saturated liquid encounters the solid or liquid carbon dioxide causing sublimation or evaporation, resulting in the formation of carbon dioxide gas or liquid which flows out of the containment structure through the containment structure outlet. The gas entering the containment structure may also have subcooled CO2 liquid or solid (snow), which replenishes the solid or liquid within the containment structure. To supplement evaporation or sublimation of the subcooled liquid or solid, heating means are used. A distribution line connected to the containment structure outlet delivers carbon dioxide gas or liquid which is flashed to gas upon release by CO2 emitters to the photosynthetic organisms.
