SINOPEC was informed that China’s first factory-based seawater hydrogen production research project was completed in Qingdao, which not only provides an exploratory solution for the coastal areas to consume renewable green power to produce green hydrogen, but also provides a new possible path for the resourceful use of highly saline industrial wastewater.
The project adopts the mode of direct hydrogen production from seawater combined with green electricity production of green hydrogen, using part of the green electricity produced by Qingdao Refining’s on-water photovoltaic power station to decompose seawater into hydrogen and oxygen through electrolysis tanks, realising the direct electrolysis of seawater for the production of green hydrogen. The hydrogen produced will be integrated into the Qingdao Refining pipeline network system and used for blending into the refining production process or refuelling of hydrogen-powered vehicles.
The project can produce 20 cubic metres of green hydrogen per hour, and is China’s first 100-kilowatt-scale factory-scale seawater hydrogen production project implemented directly in a petrochemical park and recycled into industrial processes.
