On July 26, 2025, the SPIC Da'an Wind and Solar Power to Green Hydrogen and Synthetic Ammonia Integrated Demonstration Project was officially put into operation in Jilin. Meanwhile, 12 IGBT hydrogen production power supplies delivered by Inbo New Energy were also successfully commissioned, providing reliable power support for PEM electrolyzers.
Inbo New Energy's IGBT Hydrogen Production Power Supply Products
In previous electrolytic water hydrogen production projects, electrolyzers mainly drew power from traditional power grids dominated by centralized power sources such as thermal and hydropower. However, the power for the Da'an Wind and Solar Power to Green Hydrogen and Synthetic Ammonia Project comes from a new-type power grid powered by renewable energy, which has lower power generation stability. Therefore, it imposes higher requirements on hydrogen production power supplies: they must better adapt to the volatility of wind and solar power generation, ensure the stable and efficient electrolytic water hydrogen production process, and improve the efficiency of green hydrogen output.
To meet the project requirements, Inbo New Energy designed hydrogen production power supply products adopting a two-stage topology scheme with full IGBTs: the front stage employs an IGBT fully controlled rectifier bridge to achieve rectification from alternating current (AC) to direct current (DC), actively adjusting power factor, current waveform, etc.; the rear stage adopts an IGBT chopper circuit to precisely regulate the DC output to the electrolyzer. Both the front and rear stages are fully controlled circuits, working in coordination to achieve precise control of the output voltage/current.
This hydrogen production power supply product converts the AC provided by the renewable energy power grid into the DC required by the electrolyzer, being more grid-friendly, causing less pollution, and improving the reliability of the renewable energy power grid. Meanwhile, it provides adjustable, stable, and reliable continuous DC to the electrolyzer.
Da'an Wind and Solar Power to Green Hydrogen and Synthetic Ammonia Integrated Demonstration Project
The SPIC Da'an Wind and Solar Power to Green Hydrogen and Synthetic Ammonia Project, commenced in May 2023 with a total investment of 5.956 billion yuan, is located in Da'an City, Baicheng, Jilin. It is the launching project of the "Hydrogen-Powered Jilin" initiative and a benchmark project for SPIC's green hydrogen-based operations.
The project includes 800,000 kW of new energy installed capacity (700,000 kW from wind power and 100,000 kW from PV), supported by 40 MW/80 MWh of energy storage and 60,000 standard cubic meters of hydrogen storage equipment. Designed with the concept of "green hydrogen consuming green electricity, green ammonia consuming green hydrogen, and integrated generation-grid-load-storage," it generates "green electricity" through wind and solar power, produces "green hydrogen" through electrolytic water, and then synthesizes "green ammonia" with nitrogen. After commissioning, it can produce 32,000 mt of green hydrogen and 180,000 mt of green ammonia annually, reducing carbon emissions by approximately 650,000 mt per year.
The project sets multiple global records in technology: the largest single-unit green ammonia project (180,000 mt/year installation), the largest-scale hybrid electrolytic water hydrogen production using alkaline and PEM electrolyzers (36,000 + 9,600 standard cubic meters/hour), the largest-scale DC microgrid hydrogen production (40 MW of new energy directly supplied), and the largest 48,000 standard cubic meters solid-state hydrogen storage device. Its self-developed flexible control system for "electricity - hydrogen - chemical" production has solved the problem of balancing wind and solar power fluctuations with production stability, and green ammonia has obtained the EU's low-carbon certification.
