Supercritical cryo-compressed hydrogen storage for fuel cell electric buses
On-board performance of 500-bar cryo-compressed hydrogen storage in fuel cell buses was assessed with respect to refueling, discharge, dormancy and storage capacity. The effect of para-to-ortho conversion was considered in dormancy enhancement. The Type 3 cryo-compressed tanks were modeled using ABAQUS to determine carbon fiber requirement and Fe-Safe to determine the liner fatigue life. Stainless steel liner was preferred over aluminium to meet the required 15,000 cycles within the constraint for weight and volume. The system gravimetric and volumetric capacities for the onboard storage system that holds 40 kg H2 are 7.3 wt% (2.43 kWh/kg) and 43.0 g-H2/L (1.43 kWh/L), respectively. Compared to the current baseline 350-bar compressed hydrogen storage (ambient temperature) for fuel cell buses, the 500-bar cryo-compressed storage option can achieve 66% improvement in gravimetric capacity, 132% increase in volumetric capacity, and 36% savings in carbon fiber composite. The dormancy for 95% full tank exceeds the 7-day target
