Fremont Facility for Furthering Lower-Pressure CNG Storage
Cenergy Solutions has opened a test center in Fremont, Calif. for adsorbent natural gas technology – to which it’s applying a new, patent-pending dielectic gas desorption design.
If successfully commercialized, Cenergy’s ANG technology will allow operators to fill their natural gas vehicles at pressures under 500 psi and get range similar to that available from today’s 3,600-psi compressed natural gas fills.
The technology is applicable to existing CNG cylinders (F&F, April 15). It may also be applied to 350- to 500-psi containers that are lighter and can be designed to fit in various areas of empty space in a vehicle.
NGV Fueling at Home or Business
The technology developed and commercialized at the Fremont center “will enable consumers and businesses to transition gasoline and diesel vehicles to use natural gas and refuel at their homes and businesses,” the company says.
Cenergy’s first-generation ANG system is being tested by NW Natural, a natural gas utility company covering Oregon and Southwest Washington, by The Gas Connection in Denver, and by AAAA Generator in California, the company says.
For later iterations, Cenergy will employ dielectric heating inside the ANG vessel for better natural gas desorption.
The heating “causes the natural gas to release from adsorbents in order to fuel vehicles more efficiently,” the company explains. Equipment is being developed with Communications & Power Industries, which specializes in microwave components.
Nano-Carbon Is the Key
CPI is doing model testing for Generation II ANG cylinders and for a Generation III ANG conformable tank, Cenergy says.
Cenergy’s nano-engineered polymer-based carbon material for ANG is supplied by Seattle-based EnerG2.
