Solar power drapes over one of the world's extensive hybrid fish farms in China, boasting an impressive 370,000 solar panels.
A groundbreaking fishery-solar hybrid system in China, operated by Dajin Heavy Industry, has recently been connected to the grid. This innovative project, based in Tangshan, Hebei Province, adopts a unique "power generation above, aquaculture below" model, combining solar power generation with fish farming.
The system, spanning approximately 353 hectares, features 370,000 bifacial solar panels above fish ponds. These panels are designed to harvest more power via sunlight reflecting off water, making them ideal for placement above water. The solar panels provide shade to the aquatic environment, lowering water temperatures during hot days, which benefits fish metabolism and health.
This dual-use system offers several key advantages. It reduces water temperature, improving aquatic life metabolism and reducing the outbreak of aquaculture diseases. The cooler, shaded water also helps conserve water resources, a critical factor in water-scarce regions.
The solar energy generated is used to power aquaculture operations or fed into the grid, enhancing energy efficiency. The system also reduces evaporation from fish ponds, further conserving water resources.
The fishery-solar hybrid system is expected to generate approximately 400 million kilowatt-hours of clean electricity annually. Dajin Heavy Industry claims the project effectively improves local air quality by saving 120,000 tons of standard coal and reducing carbon dioxide emissions by 320,000 tons annually.
The project represents efficient land utilization by combining food production (fish farming) and energy generation on the same footprint. This is particularly beneficial in regions with limited land availability, enabling dual-use of land without displacing food production.
The benefits of fishery-solar hybrid systems are numerous. They improve aquaculture productivity and fish health, contribute to environmental sustainability, conserve water, reduce energy costs, and support land efficiency. These systems are being deployed in various countries to harness their synergistic benefits.
In other news, advancements in technology continue to astound. A cryogenic sensor reads atomic decay in days, which could reshape nuclear safety and care. A US firm has deployed the most powerful 60 kW roll-out solar arrays for NASA's lunar Gateway. An engineer has invented a single-step method to grow plastic alternatives using bacteria, and a new tech lets scientists extract lithium from water using a cheap, scalable membrane. These innovations underscore the rapid pace of technological progress and its potential to transform various industries.
