Hitachi Energy has supplied rectifier transformers for a major electrolytic hydrogen project located in Songyuan, a city in northeast China. The project, developed by China Energy Engineering Corporation (CEEC), is part of a large-scale hydrogen industry park. These transformers are essential for providing a stable and reliable power supply, enabling hydrogen production from renewable sources and supporting the transition toward a cleaner energy future.
As the world’s leading hydrogen producer, China has identified hydrogen as a vital component of its national energy strategy. The country is actively working to replace fossil fuels with hydrogen in industrial processes and is promoting the use of green hydrogen for producing ammonia and methanol. In late 2024, China unveiled a roadmap to accelerate the adoption of clean hydrogen technologies, with a focus on reducing industrial carbon emissions and upgrading related infrastructure.
CEEC’s project is among the largest integrated green hydrogen, ammonia, and methanol facilities in the world. The development includes a phased construction of a 3-gigawatt renewable energy plant that will harness wind and solar power to produce hydrogen through water electrolysis. The green hydrogen will then be used to synthesize ammonia and methanol, creating a complete value chain from clean electricity to finished products.
Rectifier transformers play a critical role in hydrogen production via electrolysis by ensuring a steady power supply and boosting operational efficiency. Hitachi Energy’s transformers are known for their compact design, low energy losses, and high performance. They are built to withstand electrical harmonics and power surges, ensuring reliable and cost-effective hydrogen output.
With nearly eight decades of expertise in rectifier transformer technology, Hitachi Energy’s products are used in various industries including metallurgy, cement, chemical manufacturing, and now increasingly in hydrogen energy.
This initiative is part of China’s first batch of low-carbon technology demonstration projects, endorsed by the National Development and Reform Commission. It also serves as a flagship development under Jilin Province’s “Hydrogen Powering Jilin” strategy. Once fully operational, the facility is expected to produce up to 800,000 tons of green synthetic ammonia and methanol each year.
