The Guangdong Dapeng LNG Cold Energy Aquaculture Pilot Project is the first cold energy aquaculture pilot project within an LNG terminal in China. The project was launched in May 2023, began on-site construction on October 12, started trial operation on November 30, and officially went into production on December 12. The project covers an area of 438.38 square meters and is equipped with 19 fiberglass composite breeding tanks measuring 3.5 meters in length, 2 meters in width, and 1.8 meters in height, 15 cold water temperature regulation pools measuring 3 meters in length, 1.2 meters in width, and 0.6 meters in height, and 17 tailwater multi-stage purification pools of the same size. The maximum breeding scale can reach approximately 50,000 kilograms per year. The types of aquaculture include grouper, snapper, abalone, and lobster, with multiple varieties in each category that can be rotated according to seasonal and market conditions. The LNG terminal process involves the heat exchange between seawater and ultra-low temperature (-162°C) liquefied natural gas (LNG) to vaporize it into natural gas, which is then transported to downstream users via pipelines. After heat exchange, the seawater temperature generally drops to 15~25°C, becoming a unique cold water resource that is very scarce in the southern maritime areas and is highly suitable for the growth of high economic value marine products that prefer lower temperatures. Compared with general aquaculture, these marine products grow healthier in a low-temperature environment, with more delicate and elastic flesh and better taste. The Guangdong Dapeng LNG terminal is located in a sea area with excellent water quality, with most indicators reaching the national first-class seawater quality standards. It is one of the best water quality areas among more than 20 LNG terminals in the country and is particularly suitable for aquaculture. Since the lower the seawater temperature, the higher the dissolved oxygen content, the abundant dissolved oxygen is conducive to fish growth and can reduce the concentration of ammonia nitrogen substances, improving the fish habitat. Moreover, the seawater, after being sprayed down from the top of the ORV (open rack vaporizer) at high speed, is even richer in dissolved oxygen, making it a natural high-quality breeding water source.
