The patent covers the application of discrete localised reinforcement that enables significant reduction in weight and cost of composite shells of pressurised cylindrical storage tanks.

Quantum recently announced the demonstration of this technology leap for lightweight carbon composite CNG and hydrogen fuel tanks, utilising selective fibre placement, to achieve significant reduction in weight and cost and demonstrating more than 20% reduction in material utilisation.

"This is a significant patent in that it provides an elegant solution to reduce both weight and cost of fuel tanks, thus enabling more widespread commercialisation of natural gas and hydrogen fuel cell vehicles," says Brian Olson, President and Chief Executive Officer of Quantum.

"We are in the process of refining this technology for phased introduction into commercial products."

Quantum Fuel Systems Technologies Worldwide (NASDAQ: QTWW), headquartered in Lake Forest, California, USA, develops natural gas fuel storage systems and vehicle system technologies including engine and vehicle control systems and drivetrains. Quantum produces lightweight CNG storage tanks for truck and automotive OEMs and aftermarket and OEM truck integrators.
