Insights into LNG Cold Energy Aquaculture
The Dapeng LNG terminal, one of the largest LNG receiving stations in China, has successfully implemented cold energy aquaculture. This innovative project has transformed the way cold energy is perceived, turning what was once considered waste into a valuable resource. By utilizing the cold energy produced during LNG vaporization, CNOOC has created a sustainable model that integrates energy efficiency with aquaculture.
The cold energy aquaculture area resembles a marine aquarium, where species such as lobsters, groupers, and red fish thrive in controlled environments. Technical personnel continuously monitor water temperature and quality, ensuring optimal growth conditions for high-value fish species. This method not only enhances fish farming capacities but also significantly reduces energy waste.
Economic and Environmental Benefits
The economic benefits of this aquaculture model are substantial. The market price for high-value marine products cultivated through this method exceeds 100 yuan per 500 grams, and the overall costs are projected to decrease by 30% compared to traditional aquaculture practices. Additionally, the project is expected to save approximately 1.97 million kilowatt-hours of electricity annually, while reducing carbon dioxide emissions by 1,800 tons.
This pioneering approach serves as a model for green development, showcasing how energy resources can be effectively utilized to support sustainable practices in the aquaculture industry. The integration of LNG cold energy not only enhances productivity but also aligns with global efforts to reduce environmental impact.
