ACTIVE HYDROGEN STORAGE SYSTEM / AHSS

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.

Modular architecture

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.

Performance / uptime

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.

Engineering Advantages

Built for the busiest corridors.

01

Active compression

An in-line active core holds fuel at fill-ready pressure between dispenses.

02

Reduced footprint

More usable storage per square foot; retrofits without acquiring land.

03

Higher reliability

Fewer thermal cycles on primary equipment, less unplanned downtime.

04

Modular scaling

Grow from VAS 180 to VAS 720 by adding modules, not rebuilding stations.

05

Lower cost per kilogram

Higher station utilization, less energy waste per dispense.

06

Retrofit-ready

Fits transit depots, truck stops, ports, and material-handling yards.
