Generation of electricity from biomass in Australia has been quietly growing, in the areas of low cost waste fuel predominantly in the timber industry now has not developed it true potential.
The economics of steam are hard to justify under 5MW due to low efficiencies and high capital costs. Steam is easier to justify when there is a use for the excess heat (CHP), but this relies on a constant demand for heat when the system is generating.
Heat only biomass combustion systems are well established now, Steam Systems alone has excess of 30 biomass steam plants. However, the continuing and increasing demand for electricity has left power producers few economical options for truly green renewable electricity generation. Large-scale systems whilst providing economies of scale can suffer large fuel transportation costs in terms of fossil fuels used. This makes them less environmental friendly than they first appear.
Wood based biomass fuels have a much lower calorific value than fossil fuels and a low density.
Combining these factors; results in transporting biomass for large power generating systems expensive.

Small-scale power plants can reduce transport:
-
Provide power where it is needed
-
Power transmission loses account for as much as 20%
-
Reduced Reliance on Fossil Fuels
-
An increase in renewable energy use. |

Steam Engine Power

Alternative methods are currently being studied these include gasification and indirect firing of gas turbines.
-
Biomass combustion Gas Turbine system has successfully been proved
-
Biomass combustion is a base load system
-
Electrical efficiency is 27% nett
-
Lower heat loses results in overall system efficiency between 80-85%
-
Biomass combustion turbine can have a natural gas firing at a latter date doubling the kWel output
-
Biomass combustion turbine lifetime extended at the lower temperature
-
Biomass combustion based on combustion rather than gasification |
