CRRC Zhuzhou Institute's Third-Generation Alkaline Electrolyzer Completes 300+ Hours of Wind and Solar Power Fluctuation Testing, First in the Industry to Pass Third-Party Long-Term Verification

Recently, CRRC Zhuzhou Institute's AQ-1000 third-generation alkaline electrolyzer successfully completed a 300+ hour long-duration test simulating wind and solar power fluctuations at the Ordos Hydrogen Energy Alliance demonstration base, becoming the first electrolyzer enterprise in the industry to complete such a third-party long-duration test.

Test results showed that the electrolyzer's energy consumption was only 4.3 kWh/Nm³ at a current density of 3,000 A/m² (measured by the mass flow meter method), with virtually no degradation in energy consumption before and after the test. The load regulation range reached 25%–130%, with a power regulation rate of 5%/s, enabling it to perfectly adapt to the intermittent and fluctuating characteristics of new energy generation, demonstrating outstanding operational adaptability.

Adhering to the "reliable and safe" design philosophy, CRRC Zhuzhou Institute has established a rigorous full-process testing and validation system. The electrolyzer has already completed a step-by-step, full-dimensional in-house performance test covering "materials – small stacks – short stacks – full stacks." This third-party extreme test not only verified the product's energy consumption stability and sealing reliability under fluctuating conditions but also provided important technical support for the industry in addressing the challenge of adapting new energy to hydrogen production.
