New Renewable Natural Gas Project Planned for Lomira Dairy by Year’s End

LF Bioenergy and Christian Hill Dairy announced plans to develop a Renewable Natural Gas (RNG) facility that will convert dairy manure into pipeline-quality natural gas. The facility is scheduled to be commissioned in the fourth quarter of 2025.

The project will use anaerobic digestion technology to capture methane produced from manure, preventing the greenhouse gas from being released into the atmosphere. The captured gas will be processed and upgraded to RNG standards, then injected into a natural gas pipeline for use as a low-carbon energy source.

Project leaders say the facility will deliver multiple benefits, including reduced emissions, improved manure management, and a new revenue stream for the dairy. In addition to producing clean energy, the system is expected to reduce odors and improve nutrient handling on the farm.

LF Bioenergy officials noted that dairy-based RNG projects are playing an increasing role in national efforts to lower carbon intensity in the energy sector. By partnering directly with farms, the company aims to support rural economies while advancing climate goals.

Local officials said the project represents a significant investment in the Lomira area and highlights how agricultural operations can be part of the renewable energy transition. Construction planning and permitting are underway, with commissioning targeted before the end of the year.

Once operational, the facility is expected to operate year-round, contributing renewable energy to the grid while reinforcing the role of Wisconsin agriculture in sustainable innovation.
