This study demonstrates that Solid Oxide Electrolysis Cells (SOECs) can produce green hydrogen from treated municipal wastewater, presenting an innovative solution to reduce reliance on pure water sources and enhance sustainability. By optimizing thermal energy recovery, the system achieved an efficiency of 85%, generating up to 26.2 kg of hydrogen per cubic meter of wastewater. This novel approach could cover up to 20% of Italy’s 2030 energy needs, highlighting SOECs as a feasible technology for circular economy applications in hydrogen production.
