H2 storage and release cycles were started with BH: 135 mmol KHCO3 (13.5 g), 10 µmol Ru-5 (4.7 mg), triglyme/water (15 mL/10 mL), 60 bar H2, 90 °C, 18 h. After pressure release, FD was started: 90 °C, 12 h. The generated gas was measured with manual burettes. The gas was analyzed by GC. CO is undetectable in all cases (CO quantitation limit of the applied GC is <10 ppm).
