The concept of Flexyshell was born out of shared frustration. Our team—a small group of engineers with decades of combined experience in the design and maintenance of pressure systems—knew that the hydrogen economy would hit a technical plateau if it relied solely on conventional Composite Overwrapped Pressure Vessels (COPVs). We recognized that the combined stresses within thick, rigid shells inherently limited scalability, created unacceptable safety risks from brittle failure, and resulted in inefficient use of expensive materials.

We started with a fundamental question: What if we stopped trying to engineer materials to handle coupled, complex stresses, and instead, re-architected the vessel to handle only simple, pure tension?

Working together, we developed the principle of stress decoupling: using a thin, flexible membrane for hoop stress and a separate, external tendon system for axial stress. This breakthrough allowed us to overcome the size constraints of filament winding, simplify the manufacturing process, and, most critically, design a failure mode that is benign and predictable. After validating the concept's potential through extensive analysis, we filed a provisional patent, cementing our belief that Flexyshell is the structural answer the clean energy future requires.
