Horizon Delivers First 5 MW AEM Electrolyzer System to Chinese Steel Producer

Horizon Fuel Cell subsidiary HET Hydrogen has completed delivery of the world's first 5 MW Anion Exchange Membrane (AEM) electrolyzer system to Rockcheck Steel's industrial park in Tianjin, China.

The HET-A1000 unit is being installed as part of an integrated system combining photovoltaics, AEM hydrogen production, and hydrogen-enriched blast furnace smelting. The industrial site includes a 17 MW Building-Integrated Photovoltaic (BIPV) system alongside two 5 MW AEM electrolyzer systems, each with a production capacity of 1,000 Nm³/h.

The green hydrogen produced will support Rockcheck Steel Group's 'Low-Carbon Smelting Project Using Green Hydrogen,' reducing coal consumption and carbon emissions in the company's blast furnaces. Horizon introduced the HET-A1000 in late 2024, describing it as a megawatt-scale AEM product featuring low power consumption, wide operating range, rapid dynamic response, and use of low-cost materials. The company secured its first deployment with Tianjin Zhonghe Energy Management, a Rockcheck Steel subsidiary, in early 2025.

Horizon is currently working with the client to complete system commissioning and stated it will continue enhancing performance and reducing costs as it advances commercialization of megawatt-scale AEM technology.
