China's first successful direct electrolysis of hydrogen production from oil and gas field wastewater without purification

Recently, China's first successful direct electrolysis of hydrogen production from oil and gas field wastewater without purification. During the test, the hydrogen production of the demonstration prototype reached the rated value, and on-site measurements showed that the hydrogen purity reached 99.999%.

This project uses in-situ direct electrolysis hydrogen production technology from seawater without desalination, which is the first time this technology has been applied in the field of hydrogen production from industrial wastewater. It will explore the future expansion of direct seawater hydrogen production technology into the field of energy conservation and environmental protection, and provide a route reference for hydrogen production from industrial wastewater such as petrochemical wastewater and steelmaking wastewater. At the same time, the R&D team is developing 100Nm3/h large-scale equipment and systems and actively promoting project demonstrations.

The success of this direct electrolysis hydrogen production project from unpurified oil and gas field wastewater, the technological breakthrough not only demonstrates China's independent innovation capabilities in the field of hydrogen energy production, but also provides new solutions for the environmental protection treatment and resource utilization of industrial wastewater. This achievement marks China's important progress in achieving high-level scientific and technological self-reliance and self-reliance, and will contribute Chinese wisdom and Chinese solutions to the development of the global hydrogen energy industry.
