Dark fermentation for biohydrogen requires continuous alkaline dosing to control process acidification and expensive separation units to remove co-produced CO₂, resulting in high operational costs and energy consumption. Here, the authors introduce wollastonite as a dual-function agent to simultaneously enhance H₂ yield and capture CO₂.
