China’s New Plant Turns Seawater Into Clean Resources

Quick Smiles:

• Innovative Chinese plant produces pure water, affordable green hydrogen, and valuable brine from seawater.
• Facility uses waste heat for emission-free hydrogen, making the process cost-effective and eco-friendly.
• Desalinated water costs half as much as in Saudi Arabia and far less than in California, setting new industry standards.

A cutting-edge seawater desalination plant in Rizhao, one of China’s sunniest and most sustainable cities, has dramatically outpaced industry leaders by producing not only low-cost fresh water, but also green hydrogen fuel and useful mineral brine.

Thanks to advanced engineering and the use of waste heat from a local steel foundry, the plant delivers affordable, emissions-free hydrogen, along with water priced at just US$0.28 per cubic meter—less than half the cost at some of the world’s biggest plants.

“This is not just about producing a canister of hydrogen; it opens up a new path for extracting energy from the sea,” said Qin Jiangguang, senior engineer at the Laoshan Laboratory.

By recycling brine into materials for marine chemical production and maximizing renewable energy, this facility is transforming challenges in desalination into sustainable opportunities.
