Quantum Fuel Systems Technologies Worldwide Inc. (Lake Forest, Calif.), a manufacturer of natural gas, alternative fuel systems and clean propulsion vehicle technologies, announced June 12 that it has received the notice of allowance from the U.S. Patent and Trademark Office for a new patent on lightweight composite shells of natural gas and hydrogen storage tanks.

Quantum's new patent covers what the company describes as a "breakthrough" application of discrete localized reinforcement that enables a significant reduction in the weight and the cost of the composite shells of pressurized cylindrical storage tanks. Quantum recently announced the demonstration of this technology leap for lightweight carbon composite compressed natural gas (CNG) and hydrogen fuel tanks, using selective fiber placement, demonstrating a more than 20 percent reduction in material use.

"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 commercialization of natural gas and hydrogen fuel cell vehicles," said Brian Olson, president and CEO of Quantum. “We are in the process of refining this technology for phased introduction into commercial products.”

Quantum currently produces one of the lightest and highest capacity natural gas and hydrogen onboard storage systems in the world. Developed at Quantum's technology campus in Lake Forest, Quantum's advanced CNG storage systems provide dramatic weight reduction, increased fuel storage capacity, and the capability to quickly integrate these systems.

Quantum credits the breakthrough to its nearly 20 years of lightweight storage and system integration experience with strong expertise in materials, system integration, vehicle control software, emission and durability testing, validation, and manufacturing capabilities.

Quantum Fuel Systems Technologies Worldwide, Inc. is a leader in the innovation, development and production of natural gas fuel storage systems and the integration of vehicle system technologies including engine and vehicle control systems and drivetrains. Quantum produces CNG storage tanks and supplies these tanks, in addition to fully integrated natural gas storage systems, to truck and automotive OEMs and aftermarket and OEM truck integrators. Quantum provides low emission and fast‐to‐market solutions to support the integration and production of natural gas fuel and storage systems, hybrid, fuel cell, and specialty vehicles, as well as modular, transportable hydrogen refueling stations. Quantum has operations and affiliations in the United States, Canada, and India.
