China's Seawater Breakthrough: Cheap Water & Green Hydrogen for 24 Rupees

  • China has developed a revolutionary technology to produce freshwater and green hydrogen from seawater.
  • The cost of production is 24 Indian rupees per cubic meter, significantly cheaper than existing methods in Saudi Arabia and the US.
  • A factory in Rizhao, Shandong, is the world's first to use seawater and waste heat to produce these resources.
  • The process yields freshwater, green hydrogen, and mineral-rich brine, addressing water scarcity and energy needs.
  • This technology has successfully overcome the corrosion problems typically associated with using seawater for hydrogen production.

Why It Matters: China's cheap seawater tech revolutionizes water and green energy production.
