Chinese scientists have successfully developed a process of turning seawater into oxygen and hydrogen without the need for desalination, The South China Morning Post (SCMP) reports. If true, the process could provide an exciting avenue for producing large amounts of hydrogen for energy production at pennies on the dollar. Moreover, the entire process is powered by renewable sources like wind and solar. Moreover, the entire process is figuratively "swimming" in raw materials as it is situated on an offshore platform.

Working with seawater to make hydrogen can be challenging due to its complex composition of microorganisms and suspended particles. This can result in low electrolysis efficiency and equipment lifespan. The Chinese team, however, utilized an innovative new hydrogen production technology
A floating production facility measures 678 feet2 (63 m2). It has been developed to incorporate an innovative design combining a hydrogen production system with a stable offshore wind power supply system, resulting in an eco-friendly farm electrolyzing seawater into hydrogen without any adverse side effects or pollution.

According to the research team, after ten days of operation in seawater, the system managed to maintain an impressive ion rejection rate of over 99.99%, producing hydrogen that was at least 99.9% pure. To this end, the platform offers a cost-effective solution to current industrial production as it eliminates the need for desalination. If scaled up, it could produce hydrogen at around 11.2 yuan (US$1.57) per kilogram (2.2 pounds), significantly cheaper than the current mainstream cost of hydrogen production from natural gas, ranging from 20 to 24 yuan per kilogram.
