A pressure vessel for holding a pressurized fluid such as compressed natural gas ('CNG') includes two end cells and zero or more interior cells. The cell geometry ensures that the cells meet one another at tangential circular surfaces, thereby reducing the tendency of adjacent cells to peel apart. A web secured about the cells includes two sheets that are tangent to the cells. Unused volumes between the cells and the web contain wedges of foam or rubber. A valve provides fluid communication between the interior of the pressure vessel and a pressurized fluid line. The filled weight of one pressure vessel does not exceed the filled weight of a conventional gasoline tank that occupies substantially the same space as the pressure vessel. The pressure vessel may be configured with exterior recesses for engaging conventional gasoline tank straps.

Composite conformable pressure vessel

Pressure vessel end dome reinforcements are placed upon resin-impregnated fiber-wound pressure vessels to improve the strength-to-weight ratio of high performance pressure vessels, such as those that are used as rocket motors, gas generators, and the like. The reinforcement structures are assembled from gore pieces to form gore bodies over dome regions of the pressure vessels.
