On October 26, 2022, the “Hydrogen Energy Promotes Jilin” Action and the Da’an Wind and Green Hydrogen Synthesis Integrated Demonstration Project Launch Activities were held at the Clean Energy Chemical Industry Park in Western Jilin (hereinafter referred to as “Da’an Project”).
The State Power Investment Corporation（SPIC) and Jilin Electric Power Co., Ltd. adhere to the innovative practice of ensuring national energy security, orderly advancing the goal of carbon neutrality, and accelerating the large-scale and high-quality development of emerging industries, thereby paving the way for a new era in hydrogen energy utilization and green electricity conversion.
The Da’an project is designed according to the “new idea of green hydrogen system” of “green hydrogen consumption of green electricity, green ammonia consumption of green hydrogen, and integration of source-grid-load-storage”. The total investment of the project is ＄0.92 billion, and the construction site is located in the west of Jilin (Da’an) Clean energy chemical industrial park, the project will build a total installed capacity of 800MW of wind and solar, a new 220 kV booster station, supporting 40MW/80MWh energy storage, and a new 46000Nm³/h hybrid hydrogen production (50 sets of PEM hydrogen production systems, 39 sets of alkaline hydrogen production system), 60,000Nm³ hydrogen storage and 180,000 tons of synthetic ammonia plant, pre-reduced CO₂emissions of 650,000 tons/year.
The project not only aims to open up the entire industrial chain of hydrogen energy and promote the construction of a new energy system but has also achieved six No.1 technologies in China and three leading technologies worldwide. Furthermore, it has been listed as a key project in 2022 by Jilin Province and recognized as a green electricity conversion industry benchmark project by SPIC.

Source: Jilin Electric Power Co., Ltd.As a provider of large-scale green hydrogen electrolyzers and solutions, LONGi Hydrogen successfully completed the shipment of the world’s first 10,000-ton green refining and chemical demonstration project named, Sinopec’s green hydrogen project, in 2022. The technology level of the product and delivery capabilities have gained initial market validation.
The Da’an project is the world’s largest green synthetic ammonia project that was launched this year. A total of 39 sets of 1000Nmynthetic ammonia project has been implemented this year. The bidding is divided into 4 sections, and LONGi Hydrogen won 15 sets of 1000Nm³/h electrolytic water hydrogen production system, with a market share of 38.5%, ranking first in the bidding.
LONGi Hydrogen has conducted several months of research and demonstration on the Da’an project, and proposed suitable product technical solutions for the scenarios of renewable energy hydrogen production and synthetic ammonia terminal applications:
First, provide 15 sets of products with international certification for system safety and energy consumption for off-grid hybrid hydrogen production. Three sets of 4-to-1 hydrogen production systems are used for flexible ammonia synthesis (every four 1000Nm³/h electrolyzers correspond to one gas-liquid separation skid, and the hydrogen production capacity of the system reaches 4000Nm³/h), and 3 sets of 1-to-1 electrolytic hydrogen production systems are used for DC microgrid;
Second, provide the latest technology for off-grid hydrogen production. Realize the perfect combination of high current density and high hydrogen production, optimize the structure of the gas-liquid separation frame to make it more compact, and effectively reduce the system investment.
Third, provide supporting equipment and solutions for new energy flexible hydrogen production. The product has a wide range of adjustment capabilities, and it is compatible with IGBT power supplies and thyristor power supplies at the same time. It also has a fast power regulation speed, which can perfectly meet the adjustment needs of large-scale wind-solar hydrogen production under fluctuating conditions.
In the process of its development, LONGi Hydrogen will continue to adhere to the design concept of “safe and reliable, efficient and value-added”, continuously increase investment in scientific and technological research and development, actively promote technological and product innovation, and focus on improving equipment automation capabilities to create a more digital and intelligent chemical industry. The plant provides global customers with electrolyzers and green power-based green hydrogen solutions. According to BNEF, LONGi’s hydrogen energy production capacity (1.5GW) attained the first rank globally in 2022, and it is scheduled to reach 5-10GW by the end of 2025, providing reliable value-added delivery guarantees for large-scale green hydrogen projects around the world.
