Germany’s thyssenkrupp nucera is reported to have announced on 29 September 2026 that it secured a new chlor-alkali plant order from China’s Hongniu Lanzhou Environmental Protection Technology (Hongniu Lanzhou). Chlor-alkali is a process that electrolyzes brine to produce caustic soda (NaOH), chlorine and hydrogen, and is part of the basic chemical materials chain. The order value is said to be in the low double-digit million euros.
Hongniu Lanzhou is described as a subsidiary of Jiangsu Hongniu, and this is reportedly thyssenkrupp nucera’s first order from the customer. The project is reported to be located in northwest China.
thyssenkrupp nucera’s scope is said to cover licensing, engineering, procurement services, supply of key equipment and commissioning supervision. The technology applied is e-BiTAC v7, the latest-generation electrolyzer. The company is reported to state that it consumes less than 1,960 kWh of electricity per tonne of NaOH at a current density of 6 kA/m2.
Keisho Cho, CEO of thyssenkrupp nucera China and Japan, is reported to have said that the order reflects the confidence customers such as Hongniu Lanzhou place in the company’s technology, execution capabilities and chlor-alkali expertise. He also reportedly described the offering as a reliable, energy-efficient and future-ready solution for large-scale chlor-alkali production.
The order value is said to be in the low double-digit million euros. The power consumption benchmark is below 1,960 kWh per tonne of NaOH (at 6 kA/m2). The plant’s production capacity, target start-up timing and city-level location details have reportedly not been disclosed in the announcement.
The company is reported to say that the order could form the basis of a long-term partnership with Hongniu Lanzhou and strengthens its market position in northwest China’s chlor-alkali production hub.
First, because specific power consumption is a key operating-cost variable in chlor-alkali electrolysis, technology specifications that state power consumption may become a main criterion in equipment selection. Second, package supply from licensing through commissioning supervision shows that a model in which the technology provider is involved across design and equipment procurement remains viable. Third, a first order from a new customer opens the possibility of follow-on projects in a regional hub market. Fourth, with capacity and start-up timing undisclosed, the actual market impact will depend on further disclosures.
First, whether the production capacity and the construction and start-up schedule of the Hongniu Lanzhou project are disclosed. Second, how the EPC (Engineering, Procurement and Construction) contractor and follow-on equipment contracts are structured. Third, whether thyssenkrupp nucera secures additional chlor-alkali orders in northwest China. Fourth, how actual operating power consumption compares with the announced specification.
