LONGi Hydrogen supplied four 1000 Nm³/h alkaline electrolyzers, along with associated systems including power supply, control units, gas–liquid separation, and purification equipment. The systems were delivered in accordance with international standards, including relevant EU directives and U.S. industrial codes.
As of late June, all four electrolyzers had undergone energization, current ramp-up, gas separation and purity checks, venting trials, and emergency shutdown drills. Initial results indicate stable operation and production of high-purity hydrogen and oxygen. Full commissioning is expected to follow.
The project is powered by 52 MW of wind energy and is designed to produce approximately 3,000 tonnes of green hydrogen per year. The hydrogen will be used in ammonia synthesis, enabling the production of around 500,000 tonnes of low-carbon fertilizer and potentially reducing CO₂ emissions by 30,000 tonnes annually.
This marks Uzbekistan’s first green hydrogen project and represents several milestones for LONGi Hydrogen: its first large-scale deployment in Central Asia, the first successful international operation of a 1000 Nm³/h ‘4-to-1’ electrolyzer system, and the first use of its technology in a green ammonia application outside China.
Designed as a closed-loop system, the facility integrates renewable power, hydrogen production, and ammonia synthesis to support industrial decarbonization.
