Spotlighted on CCTV's 'Xinwen Lianbo' news broadcast: China's largest green hydrogen-to-ammonia project! Built with full 'hydrogen' power by CEEG

Amid the wave of energy transition, green hydrogen is gradually becoming a key force in achieving carbon neutrality. Recently, the Da'an wind-solar green hydrogen production and ammonia synthesis integration demonstration project reported by CCTV has drawn wide attention. As China's largest integrated green hydrogen-to-ammonia project, once completed and operational it will produce 32,000 tonnes of green hydrogen and 180,000 tonnes of green ammonia per year and cut carbon emissions by about 650,000 tonnes, accelerating the transformation of the energy structure and green, low-carbon development.

Behind this high-profile project, CEEG's presence is especially striking. To handle the project's complexity, the R&D team drew on exquisite technology and unremitting effort to overcome one technical challenge after another. More than ten ZHSFT series 96-pulse (48-pulse per unit) oil-immersed hydrogen-production rectifier transformers custom-built for the Da'an project have become an important guarantee of the project's stable operation.

01. Deep Accumulation, Empowering the Core

The Da'an project is an important innovative practice for China in the hydrogen field. At present, rectification devices for large-scale 1000m3/h water-electrolysis hydrogen production mostly adopt mainstream designs such as multi-pulse three-phase bridge thyristor rectifier systems. Such a system can adapt to the parameter requirements of various electrolyzers; the technology is mature and reliable, with low investment cost and a small footprint, making it suitable for new-energy hydrogen production scenarios powered by unstable sources such as photovoltaic and wind power.

Drawing on 35 years of deep technical accumulation, CEEG tailored the key power equipment solution for the Da'an project. The ZHSFT series oil-immersed hydrogen-production rectifier transformer adopts a multi-pulse thyristor rectifier system, which not only greatly compresses the equipment footprint but also optimizes the overall system architecture, and has yielded a number of invention patents and R&D achievements. In 2024, drawing on its exceptional R&D strength, CEEG was successfully accredited as a DEKRA Recognized Laboratory.

In terms of efficiency, the product achieves efficient electric energy conversion through the multi-pulse thyristor rectifier system, greatly reducing energy loss and significantly improving energy utilization efficiency. This not only fits closely with the concept of sustainable development and supports the green energy transition, but also substantially cuts operating costs and enhances economic returns for the country.

In terms of quality, CEEG has built a rigorous quality assurance system in which every step strictly follows lean production processes and quality management standards. This all-round, whole-process strict control ensures that every step of the product from production to operation is stable and reliable, laying a solid foundation for the safe and stable operation of the project.

02. Persistent Cultivation, Creating a Hydrogen Future

As an important component of future clean energy, hydrogen is vital to achieving global carbon neutrality. In the hydrogen field, CEEG has always maintained keen insight and an unremitting spirit of exploration. CEEG aims not only to be an active practitioner of carbon neutrality but also a powerful driver of the clean energy revolution, letting green energy create greater ecological value through continuous technological innovation.

CEEG's sustained investment and innovation in hydrogen projects fully demonstrate its determination and responsibility on the road to promoting green, low-carbon development and achieving the "dual carbon" goals. Going forward, CEEG will continue to leverage its technological advantages to contribute more to China's energy transition and sustainable development in more fields.
