Systems for refueling cryo-compressed hydrogen tanks and methods for operating the same

At least one non-transitory computer-readable medium comprising instructions that, when executed, cause a refueler controller to at least:

• open a first valve to defuel a vessel prior to a refuel process based on a pressure of the vessel;
• cause a mixing tank to fill with at least cryo-compressed hydrogen based on the pressure of the vessel and a pressure of the mixing tank;
• open a second valve to initiate the refuel process of the vessel;
• cause a third valve to increase or decrease a flow of supercritical hydrogen from a supercritical hydrogen source to the mixing tank to adjust a temperature of the mixing tank in response to a temperature of the vessel not satisfying a target temperature of the vessel during the refuel process;
• and
• close the second valve to end the refuel process in response to the pressure of the vessel satisfying a target pressure of the vessel.

A method to refuel a vessel with cryo-compressed hydrogen comprising:

• determining a target pressure of a mixing tank based on a pressure of the vessel;
• filling the mixing tank with at least the cryo-compressed hydrogen based on the target pressure of the mixing tank;
• determining whether a flowrate of the cryo-compressed hydrogen satisfies a target flowrate;
• adjusting the flowrate of the cryo-compressed hydrogen in response to the flowrate not satisfying the target flowrate;
• determining whether a pressure of the mixing tank satisfies the target pressure of the mixing tank;
• adjusting the pressure of the mixing tank in response to the pressure not satisfying the target pressure of the mixing tank;
• determining whether a temperature of the vessel satisfies a target temperature of the vessel;
• adjusting a flowrate of supercritical hydrogen into the mixing tank at the pressure of the mixing tank based on the temperature of the vessel and the target temperature of the vessel;
• determining whether the pressure of the vessel satisfies a target pressure of the vessel;
• and
• ending a refueling process in response to the pressure of the vessel satisfying the target pressure of the vessel.
