As a demonstrative project for global energy interconnection, the Songyuan hydrogen energy industrial park in Jilin Province is designed to establish 3,000 megawatts of installed capability in total that can produce 800,000 tons of green ammonia and green methanol annually.
The project includes the construction of 15 hydrogen storage tanks, each with the capacity of 2,000 normal cubic meters and 64 alkaline electrolysers capable of producing a total of 67,200 Nm³ per hour. It can adjust its hydrogen production efficiency from 30 percent to 110 percent, and even beyond. It accomplishes four world records: the largest scale, largest hydrogen storage, most flexible load and the largest cluster for alkaline electrolysers for hydrogen production.
The project overcomes several world-class technical challenges, including the precise matching of wind, solar, storage and hydrogen-ammonia-methanol production systems, and adopts domestic equipment in key links of production.
By integrating wind and solar power generation with energy storage, electrolysis and flexible chemical synthesis, the project tackles a major renewable energy challenge — the mismatch between intermittent power supply and the steady operating requirements of industrial chemical plants.
The first phase is expected to produce 45,000 metric tons of green hydrogen and 200,000 tons of green ammonia and green methanol annually, with an installed capacity of 800 MW powered by renewable energy. This will save around 600,000 tons of standard coal equivalent annually and reduce carbon dioxide emissions by about 740,000 tons.
