Developed by Adsorbed Natural Gas Products, Inc. (ANGP) and Ingevity, the ANG system is made possible by the performance of Ingevity’s Nuchar activated carbon that significantly lowers the natural gas storage pressure, reduces the system’s complexity and captures the environmental benefits and cost savings of natural gas when used as a transportation fuel.
Adsorbed natural gas (ANG) technology is the use of a highly porous adsorbent material to densely store natural gas molecules at low pressures (900 psi and below). Under controlled depressurization, these molecules release and exit the storage system in response to the demand of the vehicle’s engine.
ANGP is working with Ingevity as its adsorbent manufacturer because of Ingevity’s global leadership in activated carbons for more than 100 years. Ingevity is the industry leader in adsorbent-based, on-board evaporative emissions control for gasoline fueled vehicles.
Ozinga Energy has purchased an ANG-equipped Ford F-150 and installed a dedicated, low-pressure fueling appliance at its headquarters in Mokena, Illinois. Already a strong supporter of alternative fuels, a large majority of Ozinga’s fleet of concrete trucks operate on compressed natural gas (CNG).
The Ford F-150 is fitted with the 5.0L V8 with CNG prep kit, set up for bi-fuel (gasoline/natural gas) operation. ANGP/Worthington Industries NGV2 compliant, aluminum ANG cylinders provide the gas storage. Designed for 900 psig operating pressure, the cylinders are spun closed around Ingevity activated carbon monoliths.
Ozinga Energy provides public-access CNG fueling for heavy-duty trucks at six stations throughout Illinois and California, and plans to evaluate the ANG technology to further expand their alternative fuel strategy to their fleet of light-duty trucks.
Ozinga Energy joins a growing number of US natural gas utilities and private commercial fleets to pilot ANG-equipped vehicles. SoCalGas (of Sempra Energy) in California and Atlanta Gas Light in Georgia announced demonstration fleets in 2019.
ANG enables a natural gas fueling solution for light-duty vehicles such as pickup trucks, SUVs and service vans, a segment that has traditionally been underserved by alternative fuel options. ANG is 50% less costly to operate than a gasoline-only vehicle; increases natural gas usage for a gas utility by more than 60%; and reduces greenhouse gas emissions by 25% compared to similar gasoline- and diesel-equipped vehicles.
Data from existing ANG field demonstrations and Ingevity’s own employee driver program continues to showcase the simplicity of fueling with low-pressure ANG appliances and highlights the value the technology can bring to the light-duty segment.
