High-Speed Liquid Hydrogen Refueling Infrastructure for Heavy-Duty Transport

transportTestedTRL 6

Imagine trying to fill a giant swimming pool with a garden hose; it would take forever. This project builds a super-powered pump and station that can move liquid hydrogen at massive speeds. It's like upgrading from a slow trickle to a fire hose, making it practical to fuel huge ships, planes, and trains quickly.

The business problem

What needed solving

Heavy-duty transport (ships, planes, trains) cannot switch to liquid hydrogen because current refueling is too slow. This creates a bottleneck that prevents the massive scale-up of zero-emission heavy mobility.

The solution

What was built

A high-capacity LH2 refueling station including a cryogenic pump, loading/dispensing systems, and a boil-off gas management system.

Business applications

Who can put this to work

Maritime
enterprise
Target: Port Authority or Ship Operator

If you are a port operator dealing with long turnaround times for hydrogen ships — this project developed a refueling station with a flowrate of 5 to 6 tons per hour that drastically reduces docking time.

Aviation
enterprise
Target: Airport Infrastructure Provider

If you are an airport manager dealing with the difficulty of fueling large aircraft — this project developed high-efficiency cryogenic pumps and loading systems to enable rapid liquid hydrogen delivery.

Rail
enterprise
Target: Train Fleet Operator

If you are a rail company dealing with the need for zero-emission heavy hauling — this project developed a system to refill 4-6 m3 cryogenic storage tanks with high reliability.

Frequently asked

Quick answers
