DTE has begun operations at its first dairy-based renewable natural gas (RNG) project in Wisconsin at Dairy Dreams, LLC, a farm in Casco. Manure generated by the cow herd at Dairy Dreams, LLC is collected in an anaerobic digester, where methane gas is generated and captured. This methane gas is then refined to meet pipeline-quality standards, then trucked to a DTE owned facility in Newton, WI, where it is injected into a natural gas transmission line, and then ultimately used as an alternative vehicle fuel.
While DTE currently operates five landfill gas-based RNG projects, this is the company’s first dairy based project. In the coming weeks, DTE is expected to begin operating RNG facilities with three other dairy farms in the state and will also begin construction on three additional Wisconsin dairy RNG projects by this summer.
