Hitachi Energy has supplied high-performance rectifier transformers for a major green hydrogen production facility developed by China Energy Engineering Corporation (CEEC) in Songyuan, located in northeast China. This hydrogen industry park is part of an integrated renewable energy project designed to produce green hydrogen, ammonia, and methanol—supporting China’s transition toward a cleaner, low-carbon future.
The delivered transformer technology ensures a stable and efficient power supply for hydrogen production through water electrolysis, which is powered by wind and solar energy. Hitachi Energy’s advanced rectifier transformers are engineered with a compact structure, low energy losses, and high operational stability, making them ideal for large-scale hydrogen production. Their robust design also provides superior harmonic and current impact resistance, ensuring reliability and safety throughout the process.
“With our innovative transformer technology, we’re proud to support integrated renewable projects that combine hydrogen, ammonia, and methanol production—helping accelerate the global energy transition,”
said Zhang Jianhua, Senior Vice President of China and Head of Greater China Hub, Business Unit Transformers, Hitachi Energy.
Supporting China’s National Hydrogen Strategy
As the world’s largest hydrogen producer, China has made hydrogen a core part of its national energy strategy. The country is actively pursuing the replacement of fossil fuels in industrial processes and promoting the use of green hydrogen for the production of green ammonia and methanol. In late 2024, China introduced a national plan to fast-track clean hydrogen adoption, outlining specific actions to decarbonize its industrial base.
The CEEC project is one of the world’s largest integrated hydrogen-ammonia-methanol projects, aiming to deploy 3 GW of new wind and solar capacity to power electrolyzers that generate green hydrogen. This hydrogen is then used to synthesize 800,000 tons of synthetic ammonia and methanol annually, positioning the project as a key pillar of Jilin Province’s “Hydrogen Powering Jilin” initiative.
Proven Technology for the Hydrogen Economy
With nearly 80 years of experience in rectifier transformer development, Hitachi Energy has a proven track record in supplying energy conversion technologies for sectors like metallurgy, chemicals, and now hydrogen. Their solutions are helping industries reduce carbon emissions, boost energy efficiency, and accelerate the shift toward a renewable-based economy.
The Songyuan project is also among the first batch of low-carbon technology demonstration projects approved by China’s National Development and Reform Commission. It stands as a model for future hydrogen initiatives—demonstrating how integrated renewable infrastructure can deliver large-scale, climate-friendly alternatives to fossil-based chemical production.
