Solution Overview
Custom-designed for the specific operating conditions of hydrogen‑cooled thermal power plants, this solution strictly adheres to hydrogen‑use standards in the power industry. It produces high‑purity hydrogen on‑site to meet the cooling requirements of the generating unit, integrating on‑site hydrogen production, local hydrogen replenishment, and redundant hydrogen storage into a single system. This ensures continuous unit operation and emergency standby capability, while leveraging surplus off‑peak electricity within the plant to reduce hydrogen‑production costs.
Core Advantages:
Hydrogen purity and pressure are matched to thermal power plant hydrogen‑cooled generator standards, ensuring stable and controllable operation.
24/7 continuous production, with hydrogen storage and buffering to ensure emergency backup
On-site hydrogen production at the station reduces the frequency of tanker truck transportation and associated safety risks.
Adapts to power plant load fluctuations and can leverage off-peak electricity to produce hydrogen, reducing costs.
Fully automated DCS centralized control, integrated with the power plant’s existing central control system
Meets the safety, explosion-proof, and interlock protection compliance standards of the power industry
System configuration: large-scale industrial electrolytic hydrogen production unit, purified water pretreatment and purification system, high-power intelligent rectifier system, DCS centralized control system, hydrogen purification and drying module, pressure‑stabilizing hydrogen storage and buffer system, and a multi‑level safety interlock protection system.
Practical Impact: A 100 kW hydrogen‑production project has been delivered to a thermal power plant in Liaoning, achieving domestic substitution for hydrogen‑based cooling equipment. Maintenance and retrofitting of imported hydrogen‑production units at thermal power plants in Zhanjiang and Zhuhai, Guangdong, have successfully replaced the original Teledyne equipment. Leveraging industrial‑grade alkaline electrolysis technology, this solution helps power plants reduce their reliance on externally purchased hydrogen delivered by tanker trucks, mitigate storage and transportation safety risks, and ensure the continuous, stable operation of generating units.
