CRRC Zhuzhou Institute in China Successfully Launched 2000 Nm³/h Electrolyzer, Taken a Leap Forward in Hydrogen Energy Technology
Zhuzhou, Hunan Province, China, October 12, 2024: CRRC Zhuzhou Institute successfully launched the independently developed 2000 Nm³/h electrolyzer, and unveiled a large-scale flexible green hydrogen production equipment solution, which marks a significant milestone in the company's hydrogen energy industry and injects new vitality into the country’s clean energy development and the realization of the "Dual -Carbon" goals. Mr. Li Donglin, Secretary of the Party Committee and Chairman of the company, and Mr. Mei Wenqing, Deputy General Manager, attended the launch ceremony.
The electrolyzer incorporates multiple advanced technologies, boasting industry-leading high current density, ultra-low energy consumption, stable parallel operation, and full automation.
- With a maximum current density of 4000 A/m², the electrolyzer achieves a 40% improvement over traditional electrolyzers;
- With a DC energy consumption of ≤ 4.3 kWh/Nm³, meeting the national Tier 1 energy efficiency standard;
- Featuring a self-developed intelligent control system, the green hydrogen production system can flexibly adjust its output within a range of 25%-110% to accommodate fluctuating renewable energy conditions;
- Offering a solution for minimally or unmanned hydrogen production, the electrolyzer features a real-time monitoring system for cell voltage and temperature, as well as an intelligent operation platform with one-button start/stop and fully automated operation.
CRRC Zhuzhou Institute provides a full range of hydrogen energy solutions, from materials to complete systems, including electrolyzers, separation and purification, control systems, and energy management. CRRC Zhuzhou Institute offers flexible, safe, and efficient green hydrogen production systems, including off-grid solutions.
The advantages of a 2000 Nm³/h electrolyzer for various applications
Compared to the industry-standard 1000 Nm³/h electrolyzer, a 2000 Nm³/h electrolyzer can significantly reduce project costs for a 1GW green hydrogen production plant. By saving over 21,000 square meters of land (equivalent to three football fields), construction costs are reduced by more than 30%. Additionally, the electrolyzer equipment costs are approximately 20% lower, and reduced piping further contributes to a more than 20% reduction in initial investment.
For a 1GW green hydrogen project operating 8,000 hours annually at an electricity price of 0.25 yuan/kWh, the hydrogen production cost adopting CRRC’s electrolyzers is approximately 80 million yuan lower annually compared to products with a specific energy consumption of 4.5 kWh/Nm³. With a 25-year electrolyzer lifespan, the total life cycle cost savings can reach 2 billion yuan.
In the context of China's carbon neutrality goals, green hydrogen production has become a strategic focus. By replacing 5 liters of diesel with 1 kilogram of hydrogen, which reduces carbon dioxide emissions by 15 kilograms, a 1GW green hydrogen project using CRRC Zhuzhou Institute's alkaline electrolyzers can achieve a substantial reduction of 60 million tons of CO2 over a 25-year lifespan.
