TCL Zhonghuan's 1,000 Nm³/h Alkaline Electrolysis Hydrogen Project Enters EIA Public Disclosure

An environmental impact assessment (EIA) report for a new 1,000 Nm³/h alkaline water-electrolysis hydrogen production project developed by Inner Mongolia Zhonghuan Crystal Material Co., Ltd., a subsidiary of TCL Zhonghuan Renewable Energy Technology Co., Ltd., has been released for public disclosure on China’s national platform for construction-project environmental information.

Located within the Phase 3 premises of Zhonghuan PV in Hohhot, Inner Mongolia, the project will make use of existing factory buildings to install a 1,000 Nm³/h alkaline water-electrolysis hydrogen production unit. The facility is designed to produce approximately 7.2 million Nm³ of hydrogen annually.

The project has a total investment of RMB 14.14 million (approximately US$1.96 million) and will not require additional land. The newly added facilities will include electrolyzers, gas-liquid separation systems, hydrogen purification units, pure-water preparation equipment and hydrogen cylinder banks.

Existing utility systems, accident containment facilities and hazardous-waste storage areas will be utilized to support the project, minimizing the need for additional infrastructure.

Process wastewater generated by the project will be treated and recycled through the existing wastewater treatment system. Domestic sewage will undergo pretreatment before being discharged to the Jinqiao Wastewater Treatment Plant.

General solid waste will be collected and recycled by equipment suppliers, while hazardous waste will be temporarily stored in the plant’s existing designated storage area before being transferred to licensed third-party operators for compliant disposal.
