The Green Methanol Integrated Demonstration Project in Taonan City, Jilin Province, has marked a milestone with the successful production of green methanol products. The project, spearheaded by Shanghai Electric, features an electrolytic water hydrogen production unit provided by Hydrogen Era, enabling continuous supply of green hydrogen. The collaborative operation design of an alkaline electrolyzer and a PEM electrolyzer allows for an efficient 'base load + peak shaving' operation mode, optimizing green hydrogen production. The project showcases high-performance electrolyzers by Hydrogen Era, including circular alkaline electrolyzers, plug-in square alkaline electrolyzers, and PEM electrolyzers, each offering unique advantages in energy consumption and current density. Certified by a third-party institution, these electrolyzers demonstrate internationally leading performance levels. The project's success validates the feasibility of multi-tank collaborative control and integrated system design, providing a practical model for large-scale hydrogen production from wind and solar power. Additionally, the project's alignment with national strategic initiatives and its support for the commercialization of hydrogen energy in China further solidify its significance in the renewable energy landscape.
