Vessel Energy Systems

The first flat
pressure vessel.

For a century, storing gas under pressure has meant a cylinder — and the space a cylinder wastes. VESSEL is the world's first flat high-pressure vessel: the same stored energy, in a shape that fits best.

A World First

Round was the rule.
VESSEL changes that.

Since the first bar of gas was bottled, pressure has dictated one shape. VESSEL holds working pressure in a slim rectangular envelope that mounts flush, stacks well and fits neatly into the products it powers — a practical alternative to designing around the cylinder.

Our mission: make pressurised energy fit the spaces it serves, instead of making everything fit around the bottle.

The Technology

Same box.
More gas.

Put cylinders in a rectangular envelope and the corners are lost before a single bar is stored. The flat vessel is the envelope — one tank, one valve, no cage, and up to 60% more stored gas in the same space.

Three caged cylinders. One flat vessel. The same envelope.

Where VESSEL works

Technology

The first flat high-pressure vessel — how the platform works and why it wins.

Mobility

Trucks, transit, mining, vans and pickups — fuel inside the vehicle's own footprint.

Energy

Containerised storage that buffers grids and backs critical load.

On the Body

Diving, fire service and tight quarters — storage that follows the body.

Industrial Gases

Industrial Gases

Medical oxygen, everyday gas and marine suppression, flush to the wall.

VESSEL flat vessels on a city bus roofline

Transit

The roofline, reclaimed — flat vessels in a slim fairing, not domes on a bus.

Engineered in-house

Geometry, materials and manufacturing developed under one roof — the platform is ours from first principles to finished vessel.

One platform, many duties

A single flat architecture, skinned per application — the same vessel logic serves a truck, a container and a kitchen.

Three continents

Engineering, manufacturing and market development across Canada, the United Kingdom, Thailand, Singapore and Shanghai.

Wherever gas is stored, space matters.
VESSEL makes more of it.

Supported By

Vessel Energy Systems is a proud recipient of Alberta Innovates funding, supporting the development of the flat high-pressure vessel in Canada.
