Zero-downtime
hydrogen infrastructure.
The AHSS buffers, compresses, and chills hydrogen on site — so transit fleets, heavy trucks, and material handlers refuel fast and back-to-back, without waiting on the station to recover.
One platform.
Sized to the site.
Every deployment begins with the same active storage core. As throughput requirements grow, modules are added in place — from a single VAS 180 at a depot to a VAS 720 on a heavy-haul corridor — with no change to the station footprint plan.
Two stations, one fleet.
Given identical hydrogen supply and demand, a conventional station stalls between fills while it recompresses and rechills. The AHSS holds a charged buffer at fill-ready pressure, so the following vehicle is never waiting on the equipment.
Built for the busiest corridors.
Active compression
An in-line active core holds fuel at fill-ready pressure between dispenses.
Reduced footprint
More usable storage per square foot; retrofits without acquiring land.
Higher reliability
Fewer thermal cycles on primary equipment, less unplanned downtime.
Modular scaling
Grow from VAS 180 to VAS 720 by adding modules, not rebuilding stations.
Lower cost per kilogram
Higher station utilization, less energy waste per dispense.
Retrofit-ready
Fits transit depots, truck stops, ports, and material-handling yards.
