Can Clean Hydrogen Be Produced Without The Colors? - CleanTechnica

The article discusses Houston-based Utility Global’s (UG) innovative approach to producing clean hydrogen without relying on the conventional color-coded classifications (green, blue, grey) typically used in the hydrogen industry. UG’s patented H2Gen system uniquely utilizes the inherent energy in industrial waste gases—such as off-gases from steel mills and methane-rich biogas from landfills and farms—to drive hydrogen production. This method bypasses the large electricity demands of traditional water electrolysis, effectively turning environmental liabilities into a free energy source. Additionally, the system captures a concentrated CO₂ stream, making carbon sequestration more feasible and cost-effective. A key challenge of UG’s technology lies in the precise control required for the electrochemical reactions within its solid oxide reactors, as minor fluctuations in temperature, pressure, or gas composition can affect efficiency and hydrogen purity. To address this, UG partners with Rockwell Automation, which provides an advanced control system (PlantPAx Distributed Control System) that continuously monitors and adjusts process variables in real
