Role of electrolytes composition, ionic crossover and CO2 availability in bioelectrochemical methanation
• Dissolved CO 2 regulation enhances CH 4 purity up to 88% at stable production rates. • Ionic crossover causes salinity stress and limits bioelectrochemical methanation. • Electrolyte management mitigates salt accumulation and restores methanogenic activity. • Long-term stack operation identifies key constraints for scalable bioelectrochemical methanation.
