ANGP Offers Certified Adsorbed Natural Gas System for Light Duty Vehicles


Adsorbed Natural Gas Products (ANGP) recently announced that it has successfully installed the industry’s first ANSI NGV2 certified adsorbed natural gas (ANG) active storage system. The system, which ANGP calls its first generation (GEN 1) ANG System, is comprised of six activated carbon monolith-filled seamless aluminum cylinders, fully ANSI NGV2 certified for an operating pressure of 900 psig, and ANGP’s low-pressure fuel management system. The first system was successfully installed on ANGP’s 2014 Ford F-150 pick-up truck equipped with Ford’s CNG/LPG-ready 3.7L bi-fuel engine.

“Today we have met the challenge of producing a fully ANSI NGV2-certified low-pressure ANG storage system for motor vehicles,” said Bob Bonelli, co-founder and CEO of ANGP. “Our GEN 1 system proves that low-pressure storage for natural gas vehicles is not only a possibility, but a commercial reality complying with the most demanding certification standards in the industry.”

The ANGP GEN 1 ANG system features several industry firsts, including ANSI NGV2 certification, which was conducted by tank manufacturer Worthington Industries; monolith-filled cylinders, containing Ingevity Corporation’s Nuchar Fuelsorb activated carbon monoliths, developed and produced for ANGP; and ANGP’s patent pending fuel extraction and pressurization system (FEPS), which engages as tank pressure drops below 125 psig to ensure consistent fuel as the tank approaches empty. The FEPS is equipped with miniature compressor technology from Aspen Compressor.

This first production system is configured on the floor of the cargo box of the F-150. This system configuration allows for the full length and width of the cargo box to be used by installing a floor above the cylinders. Alternative configurations can be achieved by working with up-fitting companies and OEMs, include horizontal stacking in the front of the cargo box or “sunk” into a well below the cargo box of the truck to allow maximum depth while leaving the length and width of the cargo box available for use.
