Chinese desalination plant makes fresh water cheaper than tap water – plus green hydrogen

Holy grail! Desalination is salvation!

Strange both, Google and Bing search find only two news stories (and both are the same) about this important news item! One of the two articles is clearly awful spam and should not even have been retrieved as a top search result and it appears to reference the other article.

"China has launched a revolutionary facility in the eastern province of Shandong that produces fresh water from seawater for just two yuan (US$0.28) per cubic metre, generating green hydrogen as a by-product in a breakthrough that could redefine global water and energy systems."

Bing search result (based on SCMP article):
"The Shandong desalination plant in Rizhao is a groundbreaking facility that produces fresh water from seawater at a cost of just two yuan per cubic metre. This facility generates green hydrogen as a by-product and operates entirely using seawater and low-grade waste heat from nearby steel and petrochemical plants. It has achieved a "one-in, three-out" circular economy, producing 450 cubic metres of ultra-pure fresh water, 192,000 standard cubic metres of green hydrogen, and 350 tonnes of mineral-rich brine for marine chemical production. The facility's energy requirement is relatively low at roughly 4.2 kilowatt-hours per cubic metre of hydrogen produced, contributing to its economic viability and the case for replicating similar models in coastal or water-stressed regions."

'Key breakthrough' | Novel Chinese electrolyser produces hydrogen directly from seawater for 500 hours (behind paywall) "The pilot 110kW system eliminates the need for water desalination, while apparently producing H2 at similar efficiencies to conventional electrolysers"
