Topsoe signed an agreement with Zhongneng Yida to provide Topsoe HydroFlex technology and catalysts to produce SAF.

Located at the city of Shijazhuang in the Shenze Economy Development Zone of Hebei province, the facility will produce 400,000 tons of SAF annually, utilizing used cooking oil (UCO) for the feedstock. When in full operation, Topsoe’s technology will expectedly enable an annual emission avoidance of approximately 930,000 tons of CO₂e.

Zhongneng Yida expects to start construction in the third quarter of 2025 with operations to commence in first half year of 2027. It is expected the facility will initially export to the European market, with plans to also target the local market in China.

This agreement follows Topsoe’s recent announcements to provide its HydroFlex technology, proprietary equipment and catalysts to Zhejiang Jianglan Bio-Energy Technology Co. Ltd in April 2025, Guangxi Free Trade Zone Chuangui Lingang New Energy Co., Ltd in January 2025, and Guangxi Free Trade Zone Hungkun Biomass Fuel Co., Ltd in April 2024.

With HydroFlex, customers can convert various fats, oils and greases into drop-in renewable jet and diesel that meet all globally accepted specifications for these fuels. Topsoe’s HydroFlex can be deployed in both grassroots units and revamps for co-processing or fully renewable applications.
