Longi wins bid to supply green ammonia megaproject

The Da’an project in Jilin is expected to produce 180,000t/yr

Chinese renewables technology firm Longi has won a bid to supply 15 electrolysers to the first phase of the 180,000t/yr Da’an green ammonia megaproject in the northeastern province of Jilin. The full project, estimated to cost $920mn, will include 800MW of wind and solar, 40MW of energy storage, 89 electrolysers capable of producing 46,000m³/h of hydrogen, and 60,000m³ of hydrogen storage capacity. Longi has 1.5GW of electrolyser production capacity—the highest in the world, according to research firm BloombergNEF—which it plans to scale to 5–10GW by 2025. 1.5GW – Longi electrolyser production capacity While China has set a relatively modest national target of 100,000–200,000t/yr of
