How does SYRIUS work?
Spanning 54 months, the SYRIUS project aims to revolutionize the steel industry landscape by integrating a 4.2 MWel Solid Oxide Electrolyser (SOE) for producing 100 kg/h of green hydrogen into a into a real steel manufacturing plant.
SYRIUS is a European project supported by the Clean Hydrogen Partnership and its members.
Components
Solid Oxide Electrolyser (SOE) technology has great potential as an innovative high efficiency technology for renewable hydrogen production from steam electrolysis.
The favourable thermodynamics at higher operating temperatures gives a higher electric efficiency.
With respect to low temperature water electrolysers, the overall energy efficiency can be further increased by heat recovery.
The innovative features of the SYRIUS plant integration concept include the provision of hydrogen for a new reheating furnace equipped with fuel flexible burners able to operate with 0-100% hydrogen mixing with natural gas, allowing to reduce the CO₂ emissions of the process.
Additionally, the furnace can work with air enriched with oxygen from the electrolyser.
Heat recovery steam generator (HRSG) is a fully commercial and well-known technology for installation both in the power generation field and in industrial applications for heat recovery, such as the case of steel production processes.
SYRIUS will use the steam generated by the HRSG as source for the electrolyser.
SYRIUS will analyse the options for future water condensation from the flue gases.
Depending on the type of impurities which will be found during real operations, SYRIUS will evaluate the use of a Water Condensation Unit in the Solid Oxide Electrolysis Cell (SOEC) system.
