Quantum’s IP Portfolio for CNG, Hydrogen Fuel Systems Expands

Quantum Fuel Systems Technologies Worldwide Inc. says the U.S. Patent and Trademark Office has issued the company a patent that covers Quantum's pressure and flow management technology for on-board gaseous fuel storage systems, such as for compressed natural gas (CNG) and hydrogen alt-fuel vehicle platforms.

The new patent covers ‘a bi-directional fuel system comprising a fuel storage tank, a regulator, a check valve between the storage tank and the fill line and configured to allow flow into the storage tank; and a distal pressure delayer having an inlet connected to the fill line and an outlet connected to the tank valve.,’ according to the company.

‘The innovative pressure delayer provides important safety features to protect the various components during rapid natural gas refueling and consumption conditions,’ Quantum notes.

Quantum's intellectual property portfolio includes more than 60 patents (issued and pending) related to natural gas and hydrogen storage and metering systems and refueling, and hybrid-electric drivetrain systems.
