Foreign media: China has built and put into operation a world-first small-scale seawater comprehensive utilization facility in Rizhao, Shandong, which can convert seawater into fresh water at a cost of only 2 yuan per cubic meter (about 0.28 US dollars), while also producing green hydrogen and mineral-rich brine as by-products.
The facility is entirely powered by seawater and low-grade waste heat from surrounding steel and petrochemical enterprises, and has been operating stably for more than three weeks continuously without the need for additional fresh water or high-cost pretreatment. It processes 800 tons of seawater annually, producing 450 cubic meters of high-purity fresh water, 192,000 standard cubic meters of green hydrogen, and 350 tons of mineral-rich brine, achieving a circular economy model of "one input and three outputs."
The energy consumption for hydrogen production is 4.2 kilowatt-hours per cubic meter, and the annual hydrogen production can support 100 buses to travel 3,840 kilometers per year, which has significant demonstration value.
