Chinese electrolyser manufacturer Longi Hydrogen has received regional government approval to build a 1GW alkaline-electrolyser factory in Inner Mongolia, China, adding to its existing 2.5GW of annual manufacturing capacity

Longi’s new 10bn-yuan ($1.4bn) plant, in the city of Ordos, is expected to begin construction in December this year and be finished by September 2026. Upon completion, it will produce 200 sets of 5MW alkaline electrolysers annually.

The Xi’an-headquartered company, which has electrolyser factories in Xi’an and Wuxi, has won orders for its machines from ten countries so far, with its latest order being a 5MW unit and balance-of-plant delivered to an undisclosed green H2 project in Namibia.
In April last year, Longi said it planned to increase its electrolyser manufacturing capacity to between 5GW and 10MW by the end of 2025, with an eye on expanding sales beyond its domestic market.

Inner Mongolia hosts some of China’s largest green H2 projects, including the world’s largest operating plant, the first 500MW phase of Envision Energy’s 2.5GW green H2 and ammonia facility.

In addition to approving Longi’s new factory, officials from the autonomous region have also greenlit the construction of a 2.2GW green H2/ammonia project and a 1.8GW green H2/methanol facility, which are set to be China’s second- and third-largest green H2 plants.
