Hitachi Energy has provided rectifier transformers for electrolytic hydrogen production in a hydrogen industry park established by China Energy Engineering Corporation (CEEC) in Songyuan, China. This initiative aims to ensure a stable power supply for hydrogen production from renewable energy sources, aligning with China's emphasis on hydrogen as a core component of its national energy strategy. The project by CEEC is part of China's efforts to transition from fossil fuels to hydrogen in industries, particularly focusing on promoting green ammonia and methanol production through hydrogen utilization. Hitachi Energy's transformer technology, known for its compact design, low losses, and high stability, plays a crucial role in enabling efficient hydrogen production through water electrolysis. With nearly 80 years of experience in manufacturing rectifier transformers, Hitachi Energy offers solutions that are widely used across various industries, including hydrogen production. The project in Songyuan is significant as it forms part of China's large-scale green hydrogen-ammonia-methanol integrated projects, utilizing wind and solar power for hydrogen production and subsequent synthesis of ammonia and methanol. This comprehensive approach covers the entire value chain from clean electricity to hydrogen-based products. The initiative not only contributes to lowering carbon emissions and upgrading the industrial sector but also aligns with national and provincial low-carbon technology and hydrogen-focused strategies. Zhang Jianhua of Hitachi Energy highlighted the importance of green hydrogen in decarbonizing industries and reducing reliance on fossil fuels. The project is expected to produce a substantial amount of green synthetic ammonia and methanol, further driving the growth of hydrogen-based clean energy and supporting China's energy transition goals.
