Advantages of the Biomass Fired MicroTurbine

• Gas turbine operated on a clean working medium – Air

• Heat Exchanger - Simplicity & Minimal # components

• Lower environmental impacts – Eliminates the need for waste water/steam consumption or cleanup

• Commercial components available for Gasification and MicroTurbine Equipment

• Indirect fired gas turbines offer potentially higher over all efficiency

• Modular design allows for “Base Load” expansion to onsite need

Minimal R&D Investments in Biomass as a fuel have been made as compared to others such as fossil fuels and nuclear.$0 Private Industrial R&D Investments in Biomass as a “Renewable Fuel”Limited public program funding available for “DG” Biomass R&D projectsVenture Capital is non-existent for renewables in our uncertain energy market
