Study Notes
Biomass Energy Overview
- Biomass energy is an alternative to fossil fuels, aiming to reduce greenhouse gas emissions and combat climate change.
- Biomass energy comes from organic materials like sugar cane, wood, animal waste, grasses, food crops, and algae.
Biomass Feedstocks
- Biomass feedstocks include energy crops grown specifically for use in fuels, such as soy and corn.
- Organic industrial waste, like sawdust and discarded lumber, can be burned directly or converted into other energy sources.
- Algae is a promising biomass energy source due to its rapid growth and energy production.
Converting Biomass to Energy
- Converting biomass to energy involves processes like gasification, co-firing, fermentation, and pyrolysis.
- Gasification combines biomass with oxygen, producing carbon monoxide and hydrogen (syngas).
- Co-firing involves burning biomass alongside fossil fuels to reduce pollution emissions.
- Fermentation uses microbes to decompose sugars into carbon dioxide and ethanol.
- Pyrolysis involves heating biomass to produce combustible gases and bio-oil.
Biomass Energy Pros and Cons
Pros
- Biomass energy is potentially carbon neutral, as new sources absorb and sequester carbon dioxide during regrowth.
- Biomass energy is abundant, with sources like algae, corn, and soybeans.
- Biomass energy sources quickly renew themselves through continuous growth.
Cons
- Initial costs of equipment for processes like gasification and pyrolysis can be high.
- Transportation and storage of energy crops, wood pellets, and forestry waste can be cumbersome and costly.
- Dedication of arable land to energy crops reduces acreage for food crops and livestock.
- Biomass energy harvesting requires careful management to remain renewable and carbon neutral.
