        On December 18, it was learned that China's first industrial-scale seawater hydrogen production research project has been completed at Sinopec Qingdao Refining & Chemical.  The project adopts a model combining direct seawater hydrogen production with green electricity for green hydrogen production, capable of producing 20 cubic meters of green hydrogen per hour. This not only explores new solutions for coastal areas to consume renewable green electricity and produce green hydrogen but also provides a new approach for the resourceful utilization of high-salinity industrial wastewater.
