US-based decarbonisation tech company Utility Global (Utility) has produced hydrogen from blast furnace gas at a North American steel plant using its electrochemical reactor. Unlike conventional electrolysis, the system requires no electricity, potentially lowering emissions and operational costs for steelmakers.
Steelmaking is carbon-intensive and accounts for around 7% of global CO2 emissions. While green hydrogen is a potential decarbonisation solution, its production via electrolysis requires renewable electricity and infrastructure investment. Utility said its system converts industrial off-gases into hydrogen while capturing CO2 for reuse or storage.
Utility has tested the technology for over 3,000 hours at a major steel plant.
Known as H2Gen, the modular system is designed to integrate with steelmaking operations and can restart within 15 minutes after a feedgas disruption, according to Utility.
