One of two technology advances for the use of adsorbent natural gas (ANG) fuel tanks in natural gas vehicles (NGV) has been installed in a commercial fleet van by California-based Cenergy Solutions.

A fleet customer sent a 2001 Dodge Ram B2500 van with a 5.2-liter V-8 engine to Cenergy for modification to use the ANG fueling tank system, according to Fremont, CA-based Cenergy COO Gary Fanger, who said the vehicle was originally made by Chrysler to run on compressed natural gas (CNG).

Cenergy technicians added an ANG tank, then tested the van to gauge performance and gas flow to the engine. ANG has been around for the last two decades, but several technological challenges have kept it from potential commercialization until now, according to Cenergy and others in the...
