Elcogen announces SYRIUS Project in green steel

HydrogenOne Capital Growth plc, the first London-listed fund investing in clean hydrogen for a positive environmental impact, reports that portfolio company Elcogen AS ("Elcogen"), a leading European manufacturer of solid oxide technology, has announced the launch of the Horizon Europe SYRIUS project, with Acciai Speciali Terni Spa, a leader in Europe's stainless-steel sector.

The SYRIUS project will seek to decarbonise the steel production process through hydrogen production and circular energy use. The SYRIUS project, which is backed by a €10 million grant from Horizon Europe, will integrate a 4.2 MW Solid Oxide Electrolyster (SOEC) into an Electric Arc Furnace (EAF) plant, which will enable sustainable steel production.

The SOEC will be installed at Acciai Speciali Terni in Terni, Italy. The facility will have capacity of over 1,000 tonnes per annum of stainless and specialty steel produced.  Elcogen's leading expertise in solid oxide cell and electrolysis technologies will provide stacks designed for large-scale production on a specialised platform. Baker Hughes, which is a strategic investor in Elcogen, will lead the design and production of the multi-stack electrolyser, managing the installation and testing of the equipment.

As at 31 December 2024, HydrogenOne's investment in Elcogen represented 18% (£21 million) of the Company's NAV.

Dr JJ Traynor, from the Company's investment adviser, commented: "SYRIUS marks an important development for Elcogen. In collaboration with strategic investor Baker Hughes, the company is set to roll out its innovative solid oxide technology into the green steel sector, which is a first for Elcogen, and this demonstrator opens an important market for the company."

Martin Skov Skjøth-Rasmussen, CTO of Elcogen said: "This is the largest SOEC project in Europe, backed by a formidable consortium of experts. By demonstrating the SYRIUS concept in a working steel plant, we are not only advancing industrial adoption but also providing a tangible, scalable solution that will unlock new market opportunities. We're talking about decarbonizing one of the most challenging sectors and endeavouring to make it commercially viable to do so. The potential impact of this initiative is truly exciting, and we're very proud to be a part of it."
