The manure of livestock offers tremendous potential for utilizing the vertical integration of seed to finished livestock and the production of energy out of animal waste is just a no-brainer. NRES is developing cost-effective systems for use in smaller applications where cost can be dramatically reduced compared to large, commercial systems. Despite their obvious value to Nebraska agriculture, poor electric buyback rates (NO net metering) and high capital investment has limited applications in the state to one.

At NRES, we feel we can do better than that and we are working to field simple and cost effective systems that can see broad application in Nebraska. Danny Kluthe at Olean Energy in Dodge, Nebraska, can also assist in reviewing the viability of the larger systems. Some photos of Olean Energy are included below.
