The ultimate goal is to compete with conventional fueling times of diesel vehicles (roughly 10 minutes), which translates to an ambitious hydrogen gas mass flow rate of 10 kg/min average (20 kg/min peak) based on a maximum onboard vehicle storage potential of 100kg hydrogen gas. This rate is roughly 10 times the average mass flow rate currently used for light-duty FCEVs.
On April 26, 2022, the IHS team exceeded this mass flow rate goal, demonstrating an average mass flow rate of 14 kg/min (21 kg/min peak) with a 40.3 kg fill into a bank of 8 hydrogen storage tanks—similar to those used by HD vehicles—in 2.87 minutes. This intermediate milestone will pave the way for the project to meet the ultimate milestone of completing a 60-80kg fill in under 10 minutes with the fast mass flow rates.
