Part 2 of Biomass

Advantages/Disadvantages of Biomass!! :D

Advantages

  • Theoretically inexhaustible fuel source
  • When direct combustion of plant mass is not used to generate energy (i.e. fermentation, pyrolysis, etc. are used instead), there is minimal environmental impact
  • Alcohols and other fuels produced by biomass are efficient, viable, and relatively clean-burning
  • Available throughout the world

Disadvantages

  • Could contribute a great deal to global warming and particulate pollution if directly burned
  • Still an expensive source, both in terms of producing the biomass and converting it to alcohols
  • On a small scale there is most likely a net loss of energy--energy must be put in to grow the plant mass

Distrabution of Biomass

Combusting biomass feedstock to create electricity does not contribute to global warming and helps avoid the release of other harmful emissions. Also, viable fuels are produced in many industries with no additional processing costs involved, further strengthening the financial viability of new plants on favorable sites.

Typical biomass fuels include a wide variety of material. Some common fuels are forestry by-products, agricultural wastes, municipal wastes, landfill gas, and syngas. There are also many next generation biomass feedstocks in different stages of commercialization. These new fuels have the potential to dramatically scale plant sizes and the feedstock supply chain, creating significant opportunities for additional generation fleet expansion.

The Siemens steam turbine portfolio is characterized by efficiency and durability. Siemens turbines can be built to be back-pressure or condensing, and single or multi-stage. They can also be equipped with singe or multiple controlled and uncontrolled extractions to satisfy particular process or district heating and cooling requirements.
