GravitHy, Marcegaglia to cooperate on green steel
French greenfield low-carbon hot-briquetted iron (HBI) producer GravitHy, Italian flat steel and tube producer Marcegaglia and low carbon fuel company Elyse Energy have signed a memorandum of understanding (MoU) to develop complementary industrial projects in Fos-sur-Mer, France, GravitHy said in a statement on 4 February.
The agreement formalizes the shared commitment to explore and develop industrial collaborations within the Fos-sur-Mer port and industrial zone, creating a major European industrial green steel hub in the area.
The cooperation includes shared logistics, including railway infrastructure; and carbon capture and consecutive utilization of CO2 emitted by Marcegaglia for Elyse Energy’s fuel production. The companies will also collaborate on water and energy solutions, and creation of common energy storage solutions.
GravitHy is developing a low carbon HBI production plant with a capacity of 2 mt/y, which will be in operation by 2030. The project will reduce emissions by around 90% compared with conventional blast furnace (BF)-based steelmaking.
Marcegaglia is in the process of modernizing the Fos-sur-Mer plant which it acquired in 2024. After the upgrade, which is scheduled for completion by 2028, the plant will produce green steel using electric-arc furnace (EAF) technology. Capacity of the mill will be 2.1 mt/y of both carbon and stainless steel hot-rolled coil, which will be shipped for further processing to Marcegaglia’s plant in Ravenna, Italy.
In 2025, Marcegaglia signed an agreement with equipment supplier Danieli to supply the Fos-sur-Mer plant. Prior to its acquisition of the Fos-sur-Mer mill, Marcegaglia had no carbon steelmaking capacities and relied on imported slab for heavy plate rolling and on HRC purchases, mainly from outside the EU.
Elyse Energy, through its NeoCarb project, plans to start production of green chemicals, including methanol and electro-sustainable aviation fuel (e-SAF) from 2030, using captured CO2 as feedstock.
