In August 2019, SCS Energy broke ground on construction of a 4,000-scfm landfill gas to renewable natural gas plant in Indianapolis. Indy High Btu, LLC engaged SCS Energy to build the plant under an engineer/procure/construct (EPC) agreement. Indy High Btu, LLC is jointly owned by Kinetrex Energy, Southside Landfill, and EDL Energy.
The plant employs an iron redox scrubber for hydrogen sulfide removal, membranes for carbon dioxide removal and pressure swing adsorption for nitrogen removal. It is on schedule to achieve commercial operation in February 2020. Kinetrex, as a major distributor of LNG, intends to convert the biogas into LNG. This bio-LNG will fuel trucks replacing nearly 8 million gallons of diesel a year.
The Indy High Btu plant is the third landfill gas-to-biomethane 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.
