Ozinga Energy, established in 2012 by Ozinga Bros., Inc., focuses on clean fuels and renewable energy services. Based in Mokena, Illinois, the company develops and applies fuel solutions for its own fleet and for customers. It operates the largest public CNG/RNG fueling network in Chicagoland and provides end-to-end support for Time-Fill and Fast-Fill stations across the continental United States. A notable offering is a portable CNG compressor trailer packaged in a 14-foot unit, configurable for time-fill connections and capable of serving multiple Class 8 trucks overnight in temporary or semi-permanent deployments. Ozinga Energy also operates a gas-processing plant in Indiana that converts dairy-origin biogas into RNG injected into the national pipeline, with RNG that is chemically identical to natural gas but with a lower carbon footprint. The company further pursues EV charging solutions and other RNG and biogas projects, reflecting a broader engagement with alternative fuels.
