In the United States (US), officials with WTE LLC (WTE) and Hitachi Zosen Inova USA LLC (HZI USA) announced the construction of a renewable natural gas (RNG) facility that will generate approximately 120 000 MMBTUs annually from a Colorado dairy and deliver it to the California Low Carbon Fuel Standard (LCFS) market.

The announcement solidifies Wolf Creek Dairy’s commitment to sustainability, they turned to developer WTE LLC for assistance in defining and executing the project.

The WTE Wolf Creek RNG Facility is expected to begin generating RNG early this fall – enough fuel to displace approximately 1.2 million gallons of diesel off the road.

Membrane separation

HZI is supplying a 625 standard cubic feet per minute (SCFM) membrane biogas upgrading system including coarse desulphurization, raw gas pre-treatment, and a booster compressor for compressing the product gas, on-site installation, and programming and commissioning for feed-in into the local natural gas grid.

We are pleased to continue our relationship with HZI for this next dairy project. HZI has proven to be a reliable turnkey technology partner with significant in-house engineering and construction experience, said Doug VanOrnum of WTE.

This is the second project by WTE and HZI in the region.

HZI’s robust system dovetails very nicely with the world-class anaerobic digesters by DVO, Inc. that we employ, too, Doug VanOrnum said.

As businesses and governments make a significant shift to Net-Zero emissions, RNG projects like this one represent a significant environmental benefit with potential applications in many other agricultural settings across rural America.

This project reinforces HZI’s commitment to building resilient world-class renewable gas facilities in North America. We look forward to continuing working with WTE on many more projects across North America, said Heath Jones, Managing Director for HZI in North America.
