Biomass

By: Katelyn, Brady, Boaz, & MK

What is Biomass?

  • Biological material derived from living or recently living organisms
  • Renewable and sustainable source of energy
  • Examples: Scrap lumber, manure, certain crops, and forest debris

How is it Generated?

  • Biomass is burned, which releases the plant's stored energy
  • Gasification of biomass- with the absence of oxygen at high temperatures, synthesis gas or methane is produced, which can then be used in a gas engine or turbine
  • Specific equipment is required to carry out these processes

Advantages

  • long term energy
  • Improves forest health and protects wildlife habitats
  • Protects air and water quality
  • Offers most dependable renewable energy source
  • Reduce dependance on oil

Disadvantages

  • expensive and inefficient compared to fossil fuels
  • coal is 20% less costly than biomass
  • Creates methane emissions and ash

Current State of Implementation of this Energy Source

  • One of the most commonly used renewable sources of energy, second only to hydro-power
  • Accounts for almost 15% of the world's total energy supply, as much as 35% in developing countries
  • Used for off-grid electricity generation and almost exclusively on a large industrial scale
