Canada-headed biogas upgrading technology supplier Greenlane Renewables Inc, has announced that its wholly-owned subsidiary, Greenlane Biogas North America Ltd., has secured a new CA$8.3 million biogas upgrading contract with an undisclosed client for landfill gas (LFG) project in California (CA), the United States (US). The project will supply Rule 30 gas quality standard renewable natural gas (RNG) to the Southern California Gas Company (SoCalGas) pipeline.
Engineering work for the client, whose name is being withheld at this time for confidentiality reasons, will begin immediately on the California-based landfill project. Order fulfillment will begin immediately upon completion of permitting and approval of submittals by the customer, expected by early to mid-2020, with delivery expected to occur within approximately six months of commencement.
The facility is expected to process 1,600 standard cubic feet per minute of landfill gas to produce ~97 percent pure biomethane, or approximately 380 000 gigajoules (GJ) (or 360 000 million British Thermal Units (MMBTU)) annually, of RNG for direct injection into the local gas distribution network owned and operated by SoCalGas, the largest natural gas utility in the United States.
In addition, the residual off-gas, a byproduct of the biogas upgrading process, will be blended with natural gas to generate power for on-site facilities and processes.
This project is designed to achieve stringent SoCalGas Rule 30 quality specifications and according to Greenlane, it could be the first of its kind to work in conjunction with power generation to target 100 percent methane recovery.
To date, there are no projects upgrading landfill gas into RNG for injection into SoCalGas’ network.
PSA technology selected
According to Greenlane, it’s pressure swing adsorption (PSA) technology solution was selected for this project based on several criteria, including reliability, overall life-cycle cost, and ability to work seamlessly with other processes.
This project is a great opportunity to showcase Greenlane’s advanced and reliable technology. Our solution is targeting 100 percent methane capture from the landfill site. Recovered landfill methane will be upgraded and then piped directly into SoCalGas’ natural gas grid, meeting their stringent Rule 30 gas quality standards with the residual off-gas blended with natural gas for onsite power generation. This is a real win-win for the environment and generates attractive economics, said Brad Douville, President & CEO of Greenlane.
