Biomass

Biomass is a clean renewable energy resource derived from the waste of various human and natural activities. It excludes organic material which has been transformed by geological processes into substances such as coal or petroleum. The energy of biomass is extracted from different sources: wood, waste, alcohol fuels, crops and landfill gases.

1. How does it work?
The harnessing of energy from biological mass (biomass) is a simple process. The waste wood and other sources are gathered in big trucks. The waste is then transported to a biomass plant. Here, the waste is burned, the heat created is used to boil water and the energy from the steam is used to rotate turbines and generators.

2. Where can you find "plants" of this source and why?
Around the world, we can find Biomass plants in:

  • The United States: Wood parts.
  • Mauritiues: sugar cane residue.
  • Southeast Asia: Rice husks.
  • Argentina: Cereal producer.
  • United Kingdom: Animal agriculture.

3. Can it be used in Spain, why?/why not?
We can use Biomass in Spain by the existence of a forest developed sector and the population who facilitates the use of the domestic Biomass.
In Spain, we can find Biomass in:

  • Andalusia: is the autonomous community with more consumption of Biomass.
  • In Navarra and Burgos: Biomass plants burn straw to generate electricity.

4. Is it expensive?
No, it isn't, because the fuel tends to be cheap.

5. What is the effect on the environment?
The Biomass energy, causes a low enviromental impact. The Biomass energy respects the environment because it doesn't emit greenhouse gases.

6. Are you dependent of other countries/people when you want to generate electricity with this energy source?
Unlike other sources of energy, the Biomass is an autochthonous source of energy not dependent on other countries either in production or price.

7. How much electricity is generated in one plant?
Nowadays, a Biomass plant can produce 10 to 30 MW.

8. What are the advantages and disadvantages of this energy source?
Advantages:

  • It makes sense to use waste materials where we can.
  • The fuel tends to be cheap.
  • Less demand on the fossil fuels.

Disadvantages:

  • Collecting or growing the fuel in sufficient quantities can be difficult.
  • We burn the biofuel, so it makes greenhouse gases just like fossil fuels do.
  • Some waste materials are not available all year round.

9. Is it sustainable?
Biomass is a sustainable fuel, that can deliver a significant reduction in net carbon emissions when compared with fossil fuels.
