Green, Sustainable Microturbines

  1. 1. Microturbine Vertical Applications Best Value for Onsite Energy Generation CCHP CHP Resource Recovery Secure Power Resource Recovery
  2. 2. Biogas isn’t all you’re flaring Biogas Resource Recovery
  3. 3. What is Biogas Resource Recovery? <ul><li>Using otherwise flared gas as fuel for onsite power generation </li></ul><ul><ul><li>May have low Btu content </li></ul></ul><ul><ul><li>May have “sour” content (H 2 S) </li></ul></ul><ul><li>Biogases from </li></ul><ul><ul><li>Landfills • Wastewater treatment • Livestock • Food processing </li></ul></ul>
