Flexyshell At A Glance. 

 

This site introduces Flexyshell - a new concept of pressure vessel design. It can be used across many applications, from small tanks for drones to large tanks for industrial storage.

The name “Flexyshell” reflects more than just a flexible wall. It also refers to flexibility in design, tank size, and materials. This ability to adapt the tank to each specific use is what makes Flexyshell suitable for hydrogen storage, transport and distribution across very different industries.

It uses a flexible membrane with external tendon reinforcement that resolves all internal and external loads into pure tension.

That combination is what makes Flexyshell lighter, inherently safer, and significantly more cost-effective than conventional tanks, with a design that scales efficiently to sizes and applications existing technologies cannot reach.

Flexyshell was not created to compete with today’s tank technologies, but to fundamentally replace them.

It is a new class of modular pressure vessels based on one unifying idea: that the strongest and safest structures are those working purely in tension. The principle is simple, but it changes everything.

 

You are invited to explore the concept of Flexyshell, examine the data, and join us in shaping the future of high-pressure energy containment.

 

How the Concept Was Born

Today, hydrogen is mostly stored in composite overwrapped pressure vessels (COPV). This is actually space technology from the 1970s, originally designed for single use. These tanks were never meant for industrial applications, but they have been pushed into that role simply because there was no alternative.

Engineers who work on COPVs know everything about COPVs — but they typically have no exposure to how pressure is handled in flexible risers, tendon-supported systems, or prestressed structures.

Flexyshell was born by combining well-established engineering principles from different disciplines to create a completely new concept. Those principles came from multiple industries that normally never talk to each other. That cross-disciplinary view simply doesn’t exist inside most highly specialized teams.

Large organizations tend to optimize within existing frameworks. They refine materials, improve manufacturing, add safety factors — but they rarely abandon the core architecture they already invested in.

But Flexyshell is not an improvement of the existing tanks, it’s a different way of building pressure vessels altogether.

 

Vision: Implementation and Transformation

The vision for Flexyshell is to see this concept implemented at the scale the hydrogen economy truly needs.

That process has now begun. Flexyshell has entered the proof of concept phase, and the first prototype pressure vessel is currently being designed and built. This initial prototype is focused on validating the core structural principles of the technology and providing the foundation for progressively larger and more advanced vessels.

The long term potential of Flexyshell extends far beyond this first prototype. It is not intended as a niche product, but as a generalized structural system that could transform pressure vessel infrastructure across multiple applications:

  • Extreme Scalability: Our goal is to develop pressure vessels tens of times larger than conventional composite tanks, enabling cost-effective bulk storage and transport of hydrogen.
  • A step change for hydrogen mobility: For cars, trucks, locomotives, and UAVs, Flexyshell’s lighter structural approach could make it possible to store significantly more hydrogen without increasing tank weight. This could raise usable hydrogen content from today’s typical ~5% toward a practical 7–10%, not through incremental optimization, but through a fundamentally different way of carrying pressure loads. The result could be longer range, higher payload, and improved economics across hydrogen powered vehicles.
  • Safety and Sustainability: Our goal is to establish a new approach to pressure vessel safety, where the structural architecture is designed to avoid catastrophic failure modes, while the use of thermoplastic and metallic components supports recyclability and a more sustainable hydrogen industry.

With the first prototype now under development, the next step is to collaborate with partners, including engineers, researchers, investors, industrial companies, and organizations that can help validate, develop, scale, and ultimately commercialize the technology.
