Sungrow Brings the World’s Largest Green Hydrogen–Ammonia–Methanol Project Online

Sungrow has reached a major milestone in the global energy transition with the successful commissioning of the first phase of “Qingqing No. 1,” the world’s largest green hydrogen–ammonia–methanol integrated project, located in Jilin Province, China. The project officially entered operation in December 2025, while construction of the second phase is already underway.

As the core hydrogen technology supplier, Sungrow Hydrogen delivered and commissioned its hydrogen production system ahead of schedule, achieving stable operation and consistently high-purity hydrogen output from day one. The early success of the system highlights both the maturity of Sungrow’s hydrogen technologies and their readiness for large-scale industrial deployment.

A New Benchmark for Power-to-X at Industrial Scale

The Qingqing No. 1 project is designed as a phased development with an ambitious long-term vision. Once fully completed, it will integrate 3 GW of renewable energy generation capacity and enable the annual production of approximately 800,000 tonnes of green synthetic ammonia and methanol. This model allows surplus renewable electricity to be locally consumed and converted into high-value chemical products, addressing both grid flexibility challenges and industrial decarbonisation needs.

Beyond its scale, the project has established four global records:

• the largest integrated green hydrogen–ammonia–methanol project worldwide,

• the largest hydrogen storage capacity ever deployed,

• the widest operational load-flexibility range across the full process chain,

• and the largest single deployment of alkaline water electrolysis systems.

Together, these achievements mark a significant step forward for Power-to-X technologies moving from pilot concepts to fully industrialized solutions.

Flexible Hydrogen Production for a Variable Renewable World

At the heart of the project lies Sungrow Hydrogen’s flexible green hydrogen production system, engineered to cope with the inherent variability of renewable energy sources such as wind and solar. By maintaining stable operation across a wide range of load conditions, the system ensures high efficiency even under complex and fluctuating inputs.

Extensive validation under real-world operating scenarios has confirmed the system’s reliability, positioning it as a scalable solution for future large-scale hydrogen projects. This capability is critical not only for chemical synthesis applications, but also for the broader hydrogen economy, where flexibility and stability are essential to commercial viability.

Scaling Hydrogen from Demonstration to Infrastructure

Projects like Qingqing No. 1 signal a shift in green hydrogen development—from experimental installations to industrial infrastructure capable of supporting national and global decarbonisation strategies. Sungrow’s role in delivering standardized, high-capacity hydrogen equipment demonstrates how technology providers can accelerate this transition by reducing complexity, improving reliability, and enabling repeatable project models.

By integrating renewable power generation, hydrogen production, storage, and downstream chemical conversion into a single ecosystem, the project offers a blueprint for how excess green electricity can be transformed into dispatchable, transportable energy carriers.

A Strong Signal for the Global Hydrogen Market

The successful commissioning of the world’s largest green hydrogen–ammonia–methanol project underscores the growing maturity of hydrogen technologies and their expanding role in the energy system. For energy developers, industrial users, and policymakers alike, it sends a clear signal: green hydrogen is moving rapidly toward scale, standardisation, and real economic impact.

With proven performance under demanding conditions, Sungrow’s hydrogen solutions are now firmly positioned as a cornerstone technology for the next phase of the global energy transition.
