Information on the Target

GravitHy is a pioneering company based in Paris, France, dedicated to the production of sustainable iron. Established in 2022, GravitHy aims to contribute to the growth of a decarbonized steel market by producing reduced iron utilizing low-carbon hydrogen, significantly reducing emissions in the steel industry. The company plans to construct a hydrogen direct reduction iron manufacturing plant in the Fos-sur-Mer region of southern France, with an anticipated start of trial operations in 2028 and full operations in 2029. The total investment for this plant is projected at €2.2 billion, expected to create up to 500 direct jobs.

Equipped with around 750 MW of electrolyzer capacity—one of the largest in France and among the largest globally—the plant aims to produce 2 million tonnes of Direct Reduced Iron (DRI) and Hot Briquetted Iron (HBI) annually. This endeavor not only supports the steel demand but also strives to reduce greenhouse gas emissions, addressing the sector's significant ecological impact.
