Sunlight Hydrogen Energy's 2,000 Nm³/h Electrolyzer Delivers First-Year Performance Report: 3,200 Hours of Operation and 1,000 Start-Stop Cycles in Testing

Recently, Sungrow Hydrogen Energy announced that its HyGrow 2000 Nm³/h electrolyzer has successfully passed a rigorous practical test on the first anniversary of its launch. In a test simulating the fluctuating operating conditions of real-world wind and solar power generation, the electrolyzer accumulated over 3,200 hours of stable operation and completed 1,000 start-stop cycles. With outstanding measured data, it demonstrated exceptional performance in durability, efficiency, and stability, marking the product's true capability to adapt to large-scale green hydrogen production.

To address the core challenges in green hydrogen production scenarios, the HyGrow 2000 Nm³/h electrolyzer has undergone a series of forward-looking technological innovations. In terms of long-term durability, its bipolar plates adopt a unique composite solution of "corrosion-resistant alloy + laser cladding," combined with uniform-flow channels and buffer structure design, reducing coating porosity to below 1%. This fundamentally mitigates risks of erosion corrosion and localized high temperatures, enhances corrosion resistance by 3–5 times, significantly extends equipment lifespan, and delivers superior life cycle costs for customers.

In the aspect of high efficiency and low consumption, the product innovatively optimizes flow channel structure and electrolyte circulation system, effectively increasing the current proportion in the main reaction zone and suppressing side reactions. This breakthrough ultimately achieves a 3% improvement in current efficiency, directly leading to a noticeable reduction in system energy consumption and creating direct economic value for customers.

Particularly noteworthy is that this electrolyzer is specifically designed for unstable wind and solar energy input, featuring highly stable and reliable characteristics. Its "dual-safeguard" design—comprising reverse-current-resistant electrodes and a dynamic sealing system—serves as the key to handling frequent fluctuations. High-activity composite catalysts and advanced coating technology ensure performance stability during frequent start-stops, while modified composite sealing materials and a preload automatic adjustment system guarantee zero-leakage safety during long-term operation.

The industry believes that the comprehensive technological breakthroughs of Sungrow Hydrogen Energy's HyGrow 2000 Nm³/h electrolyzer not only present a convincing anniversary report but will also strongly advance the dream of large-scale green hydrogen application, steadily turning it into reality.
