The Norwegian company originally attained 75% of the facility in 2021 and has since upgraded the site to a 500MW-per-year electrolyser plant.

Tianjin has supplied equipment for two of the world’s largest green hydrogen projects, according to HydrogenPro. The firm designs and supplies high-pressure alkaline electrolyser at the plant.

The final 25% stake was purchased for CNY 3m ($400,000) in cash plus equipment worth CNY 1.8m ($250,000).

“This transaction is in line with HydrogenPro’s strategy of streamlining operations. We are pleased to secure full ownership of the plant, which is a very cost-efficient set-up with capacity to deliver on large projects,” explained CEO Jarle Dragvik.

“HydrogenPro is, as previously communicated, in dialogue with Longi under the cooperation agreement about optimisation of manufacturing footprint and further synergy recognition.”

Under the agreement with Chinese electrolyser OEM Longi, HydrogenPro could secure up to NOK 140m ($12.3m) in new equity as part of a wider partnership covering technology, manufacturing optimisation, and joint project development.

Both the deal with Longi and the acquisition of the Tianjin plant will help the Norwegian firm balance low-cost manufacturing in China with compliance in European markets, where stricter “Made in Europe” rules shape procurement and funding.
