SYRIUS project launched to decarbonize steel industry Elcogen has announced the official launch of the Horizon Europe SYRIUS project, which aims to transform the steel industry by enabling hydrogen production and circular energy use within the steelmaking process.
Backed by a € 10 million grant and a timeline of less than five years, the project seeks to make a significant impact. At its core, SYRIUS will demonstrate the integration of a 4.2 MWel Solid Oxide Electrolyser( SOEC) into a real Electric Arc Furnace( EAF) plant, paving the way for more sustainable steel production. This electrolyser will be demonstrated at a steel plant in Terni, Italy, operated by Acciai Speciali Terni.
The SOEC will produce 100 kg / h of green hydrogen to help power a fuel-flexible 280 ton steel / h, 84 MWth slab reheating furnace. The electrolyser will work in tandem with the furnace, hydrogen storage, flexible energy loads, and two virtually integrated solar PV plants, all coordinated by a cutting-edge Energy Management System( EMS). SYRIUS will place industrial circularity at its heart by harnessing furnace off-gas heat recovery to generate steam for the SOEC, recovering byproduct oxygen in the furnace, and exploring water recycling options. The project is expected to cut CO 2 emissions from the steel reheating process by 5,600 tonnes per year.
According to Emerson, it offers exceptional leaktight performance, resistance to embrittlement, reliable seat tightness, and long service life. Traditional PRVs are often unsuitable for hydrogen, which can diffuse into metal components and cause embrittlement, increasing the risk of leaks and failure. Type 84 PRVs are specifically engineered for these challenges, with pressure ranges from 6,000 to 20,000 psig( 413 – 1,379 barg) for hydrogen and helium, and up to 21,756 psig( 1,500 barg) for other gases.
The valve reaches full lift at less than 5 % overpressure and ensures zero leakage at 90 % of set pressure. A unique cartridge assembly design ensures uniform spring pressure and secure seat sealing. Each valve is factory tested with helium and nitrogen, widely accepted substitutes for hydrogen.
Type 84 PRVs meet major industry safety and performance standards, including ASME Sections VIII and XIII, NB certification, and API 527.
Emerson introduces new PRV for highpressure gas applications Emerson has introduced the Anderson Greenwood Type 84 Pressure Relief Valve( PRV), designed to protect tanks and vessels used in hydrogen and other high-pressure gas applications.
The Type 84 PRV features Arlon ® 3000XT thermoplastic seating and ASME SA-479 Type S21800 stainless steel spindle material.
