Landfill Gas to RNG Plant – GHG Reductions and Economical

September 4, 2019

In August 2019, SCS Energy broke ground on construction of a 4,000-scfm landfill gas to renewable natural gas (RNG) plant in Indianapolis. Indy High Btu, LLC engaged SCS Energy to build the RNG plant under an engineer/procure/construct (EPC) agreement. Indy High Btu, LLC is jointly owned by Kinetrex Energy, Southside Landfill, and EDL Energy.

The RNG plant employs an iron redox scrubber for hydrogen sulfide removal, membranes for carbon dioxide removal and pressure swing adsorption for nitrogen removal. The plant is on schedule to achieve commercial operation in February 2020.

Kinetrex, as a major distributor of LNG, intends to convert the RNG into LNG. RNG from the plant will fuel trucks replacing nearly 8 million gallons of diesel a year. RNG is less expensive than diesel and significantly reduces the emission of methane and other greenhouse gases.

The Indy High Btu RNG plant is the third landfill gas-to-RNG plant designed by SCS to employ nitrogen removal, meeting pipeline specifications and maximizing gas recovery. Two other plants, including a 5,000-scfm project in Kentucky, which commenced operation in March 2018, and a 5,000-scfm project in Texas, which is currently under construction and scheduled to begin operations in November 2019, are both SCS Energy designs.

SCS Energy is a practice of SCS Engineers specializing in Biogas, Anaerobic Digestion, Renewable Natural Gas and Energy Systems for industrial and agricultural operations.
