Press Release : Elogen and Sarralle sign green hydrogen generation collaboration agreement for the steel industry

Elogen and Sarralle announce the signing of a collaboration agreement for the engineering, manufacturing, supply and commissioning of green hydrogen generation equipment for the steel industry.

Elogen, a leader in PEM[1] electrolysis, specialized in the design and assembly of electrolysers to produce green hydrogen, and Sarralle, a world leading design, engineering, manufacturing and installation company, have signed a collaboration agreement for the engineering, manufacturing, supply and commissioning of green hydrogen generation equipment for the steel industry. Both companies will work together to design and manufacture green hydrogen generation equipment, and to integrate both containerized and electrolysis plant solutions into the industry.

The collaboration includes the development of pilot projects of green hydrogen as a primary fuel source for the steel industry and the construction of electrolysis plants on said industrial sites. The steel sector, which generates around 9% of the world’s total CO2 emissions, is carrying out decarbonization actions in accordance with the European Union’s objectives to achieve a carbon-free economy by 2050.

The decarbonization of the steel industry will require significant technological advances, amongst which green hydrogen will play a key role. Additionally, customers are demanding lower carbon footprint products, investors are expressing increased interest in a sustainable industry, and regulations on CO2 emissions are becoming stricter. Decreasing renewable energy costs and improved electrolyzer technologies are expected to improve green hydrogen-based steel cost competitiveness.

Jean-Baptiste Choimet, Managing Director of Elogen, comments: “With this collaboration agreement, Elogen takes its technological solutions a step further towards their integration in energy-intensive industries. Sarralle will provide Elogen solutions with access to major global players in the steel industry. We look forward to incorporating our technology into future projects to help decarbonize this industry.”

Roberto Arroniz, Managing Director of Sarralle E&E: “Sarralle with international experience in the Steel, Energy & Environment sectors, we consider Elogen to be the ideal strategic partner to extend our hydrogen technology solutions, and provide the steel industry with a complete solution for green hydrogen, to achieve their decarbonization goals. These solutions encompass from hydrogen generation and its integration in the steel plants, to hydrogen combustion equipment.”
