Hydrogen Matrix Storage

Hydrogen Storage Revolution

Revolutionary capillary matrix technology for Hydrogen Storage replaces traditional heavy composite cylinders with lightweight, flexible hydrogen tanks for any shape or application.

Modern Solution

Capillary Matrix versus Traditional Composite

Traditional storages suffer from

Heavy tanks

Bulky and heavy, reducing payload and efficiency

Limited shapes

Rigid cylinders can’t fit compact or aerodynamic spaces

High leaks

Any damage causes total hydrogen loss

Our solution offers

Capillary matrix system

3 times lighter than traditional Tanks

Any shape possible

Flat, flexible, aerodynamic forms

Isolated damage

In case of leaks only affected capillaries lose hydrogen

Custom storage design

We engineer capillary-matrix hydrogen storage systems that conform to your geometry flat, curved, thin, or modular, integrate with your powertrain, and meet the pressures and standards your application requires.

Our micro-capillary architecture enables thin, non-cylindrical tanks that slip into spaces conventional composite cylinders can’t—unlocking efficient packaging across mobility, aviation, industrial, and energy sectors.

Our team stays with you from first sketches to certified hardware in the field: requirements capture, design, simulation, prototyping, and integration.

use cases

Vehicles & Mobility

Slim, modular tanks that cut system mass, free interior volume, and raise usable H₂ for real-world range.

In road and specialty vehicles, the same ability to make tanks in non-cylindrical forms lets you use the same 30 L capacity with far less system mass (13 kg vs 33 kg) and tuck modules into sills, tunnels, under-floor trays, or roof beams.

That frees trunk and cabin volume, simplifies crash-structure packaging, and raises the usable hydrogen fraction (9% vs 3.6% at 700 bar) – so the real-world range per fill grows without enlarging the vehicle. The multi-module layout also makes service easier and reduces long plumbing runs.

UAVs & Aircraft

Aerodynamic, airframe-shaped storage that extends endurance and stabilizes CG without adding drag.

Our capillary-matrix tanks can be shaped into low-drag fairings or wing/fuselage panels instead of hanging a bulky cylinder under the airframe.

That aerodynamic integration translates directly into longer missions at the same power – 108–140 minutes vs 54 minutes with composite tanks – while also improving stability in crosswinds and leaving more room for payload and avionics. Because the storage is distributed, designers can place mass closer to the center of gravity and fine-tune balance without redesigning the airframe.

Cross-Sector Enablement

Higher energy density in practical form factors – removing weight/packaging barriers to hydrogen adoption.

Across sectors, the technology removes key engineering blockers to hydrogen adoption. Higher specific energy (~880 Wh/kg vs ~293 Wh/kg in typical UAV systems) and higher volumetric energy (415–539 Wh/L at 700–1000 bar) mean more energy in the same weight and footprint, enabling longer flight times, practical vehicle packaging, and compact portable power.

The capillary architecture localizes any damage and minimizes auxiliary hardware, so projects that were previously constrained by weight, drag, or form-factor limits can move forward with simpler integration and better safety margins – without changing your platform’s core design.
