Hitachi Energy has supplied rectifier transformers to a large-scale green hydrogen initiative in Songyuan, northeastern China, developed by China Energy Engineering Corporation (CEEC). The equipment will ensure a stable power supply for hydrogen production via electrolysis, enabling the conversion of renewable energy into clean fuels such as ammonia and methanol.
The project, considered one of the world’s largest integrated green hydrogen-ammonia-methanol developments, involves the phased construction of a 3-gigawatt (GW) wind and solar power facility. The hydrogen produced will feed into the synthesis of ammonia and methanol, establishing a fully integrated value chain from renewable electricity to low-carbon chemical products.
China, currently the world’s largest hydrogen producer, has positioned hydrogen as a key pillar of its national energy strategy. A government plan released in late 2024 outlines the accelerated adoption of clean hydrogen across heavy industries, with specific measures to curb emissions and modernise energy-intensive processes.
The rectifier transformers from Hitachi Energy play a crucial role in maintaining the reliability and efficiency of the electrolysis process. Designed for high stability and low energy loss, the equipment provides resistance to electrical harmonics and surges, ensuring safe and consistent hydrogen production.
Commenting on the development, Zhang Jianhua, Senior Vice President for China and Head of the Greater China Hub, Business Unit Transformers at Hitachi Energy, said: “Green hydrogen is central to the decarbonisation of heavy industries. By supporting CEEC’s integrated project with our transformer technology, we are contributing to China’s energy transition and advancing the global shift towards cleaner fuels.”
The CEEC-led project has been designated a key demonstration site by China’s National Development and Reform Commission and is a flagship component of Jilin Province’s “Hydrogen Powering Jilin” initiative. Upon completion, it is expected to yield 800,000 tonnes of synthetic green ammonia and methanol each year.
