RNG and Brown Gas Virtual Pipelines™ for Landfill Operations
Confidential Blue-Chip RNG Offtaker | Landfill Site, ME | Agriculture
XNG deployed dual Virtual Pipeline™ systems to transport RNG and brown gas at a Maine landfill, bridging pipeline delays for a confidential blue-chip offtaker.
The Problem
A leading RNG offtaker required an interim solution to move captured landfill RNG before a permanent pipeline connection was complete. With RNG production at 1,200 MMBtu/day, delays in interconnection created a risk of flaring or wasted gas. At the same time, the landfill required an on-site energy source that wouldn’t consume its RNG output. A flexible, dual-fuel transport system was needed to support ongoing operations and preserve renewable gas for offsite use.
The Solution
XNG implemented two coordinated Virtual Pipeline™ systems: one delivering brown gas to power landfill operations, and another transporting RNG offsite for injection at XNG’s first of its kind merchant RNG injection facility in Eliot, Maine. XNG upgraded its Eliot, ME facility to meet EPA-BRRR RNG injection standards, making it the first such site in the Northeast U.S. Both systems were commissioned in April 2024, providing the client with an immediate, compliant, and scalable solution for managing RNG and fossil fuel needs.
- First audited RNG injection facility in Northeast U.S.
- Simultaneous delivery of RNG and brown gas
The Results
XNG’s dual-pipeline model enabled uninterrupted RNG capture and on-site energy supply ahead of pipeline completion. The Eliot facility’s EPA-audited capabilities ensured regulatory compliance, while mobile infrastructure mitigated project delays. This modular solution gave the client flexibility, resilience, and a pathway to full commercialization, showing how virtual infrastructure can unlock RNG value early in the lifecycle. With 1,200 MMBtu/day RNG production secured, and a daily capacity of over 10,000 MMBtu per day, the project set a precedent for modular, compliant RNG deployment in the region.
