Cenergy Solutions Completes Successful Testing of ANG Technology

 

Cenergy Solutions has successfully completed its first round of field tests at the Clean World/Refuel CNG station in Sacramento, California. The results showed that four times more bio-methane was stored in the same size Adsorbent Natural Gas (ANG) cylinder compared to a conventional CNG tank without an adsorbent. Cenergy Solutions is continuing to do cycle testing to determine if the adsorbent natural gas will continue to perform at this level over time.

ReFuel currently stores biomethane in two 20,000 gallon storage tanks.  It is believed that they can store up to four times more biomethane gas—and perhaps more—in these tanks with an ANG system. ReFuel contacted Cenergy Solutions to field test the ANG system as a way to enhance their storage volume as production increases from CleanWorld’s digester over time.

“The results exceeded my expectations,” said Gary Fanger, COO of Cenergy Solutions said. “This test was conducted with our Generation I ANG cylinders. With our Generation II ANG cylinders, I expect the storage to substantially exceed the first test results.”

Cenergy Solutions’ ANG technology can be applied to virtually any type of natural gas storage system, including CNG vehicles, fueling stations, natural gas transport trucks and stationary natural gas storage. Cenergy is now retrofitting existing DOT compliant natural gas cylinders with their proprietary ANG system. This equipment will also make it possible to use low pressure (350–500 psi) tanks that are lighter and can be conformed to fit in various areas of empty space in a vehicle.

Cenergy’s technology can create a market for compact, affordable, low-pressure CNG Home Refueling Appliances (HRA’s) that will allow consumers to conveniently fill their vehicles at home by connecting directly to their utility gas line. It will also allow for CNG refueling equipment to be more easily and cost-effectively added to the network of public gas stations and truck stops due to the significantly lower capital investment associated with lower compression requirements.
