Renewable Natural Gas (RNG) Production Starts at Clover Hill Dairy

Site Features CMD Gas Compression Equipment and Site Controller

(Campbellsport, WI) – A new gas processing facility at Clover Hill Dairy will provide clean transportation fuel for the growing renewable natural gas (RNG) industry.  The facility to upgrade the biogas produced from an existing digester will be managed by Nacelle Solutions in partnership with U.S. Gain, a leader in the development and distribution of RNG.

Nacelle will own, operate and maintain the equipment, which includes advanced natural gas compression technology, a centralized site controller and site support from CMD CNG Energy Solutions. The Clover Hill site is the first in a series of four Nacelle Wisconsin RNG farm projects involving CMD as an equipment and service vendor. The remaining three are scheduled to be operational within the next few months.

“Along with the latest in gas compression technology, CMD has developed a centralized site controller unique to the industry for the Clover Hill project,” says Brad Schmoll, CMD CNG Business Development Manager.  “The site controller connects the discreet components of the facility and provides centralized control, as well as consistent collection of metrics that are important for reporting to the EPA for the RIN program, and to verify that the gas is of pipeline quality.  The intuitive HMI color touch screen also provides productivity and output data and has built-in alerts for any component or system issues.”  The system delivers critical data in near real-time, improving operational efficiency and ensuring uninterrupted production.

U.S. Gain will coordinate the transportation of pipeline-grade gas for all four farms through one centralized injection point using a virtual pipeline, which utilizes tube trailers to move the gas without the need for a physical pipeline.

The Clover Hill Site was commissioned and operational in under 9 months, a considerable achievement considering the complications that can occur with RNG projects.

“Nacelle is pleased to have completed the Clover Hill Dairy RNG project on schedule and within budget and we are pleased with the smooth start-up,” said Gov Graney, Managing member of Nacelle Solutions, “A component of this success is attributable to selecting vendors like CMD, with the unique skill-set of advanced technology development in natural gas for fuel compression.”
