Hitachi Energy has supplied rectifier transformers for a green hydrogen production facility in Songyuan, northeast China, developed by China Energy Engineering Corporation (CEEC). The site is one of the largest green hydrogen-ammonia-methanol integrated projects globally.

The transformers are a critical component of the electrolysis process used to generate hydrogen from renewable sources. The system supports a stable power supply and is designed for high efficiency, harmonic resistance, and low energy losses--key factors for the industrial-scale production of green hydrogen.

The broader project involves phased construction of a 3-gigawatt wind and solar power base, with energy used to electrolyze water and produce hydrogen. 

China, already the world's largest hydrogen producer, is actively expanding green hydrogen as a part of its national energy strategy. In late 2024, the country released a plan focused on clean hydrogen adoption in industry and reducing dependence on fossil fuels.

Zhang Jianhua, Senior Vice President of China and Head of Greater China Hub at Hitachi Energy, stated: "With our innovative transformer technology, we're pleased to support our customers in building integrated projects of renewables, hydrogen, ammonia, and alcohol and jointly driving the growth of hydrogen-based clean energy and the process of the energy transition."

The initiative is part of the first batch of low-carbon technology demonstration projects approved by China's National Development and Reform Commission and is a flagship effort under Jilin Province's "Hydrogen Powering Jilin" initiative. The facility is expected to produce 800,000 tons of green synthetic ammonia and methanol annually.
