What is biomass?

Biomass refers to organic matter that comes from living or recently living organisms, including plants, animals, and waste products. It serves as a renewable energy source, playing a crucial role in reducing reliance on fossil fuels. Common biomass materials include wood, agricultural residues, and municipal solid waste.

Types of biomass

  • Wood and wood residues: The largest source of biomass energy today is agricultural residues, which include straw, corn stalks, and other crop waste.
  • Animal waste: Manure from livestock can be converted into energy.
  • Municipal solid waste: Organic waste from households and industries.

Biomass conversion processes

Biomass can be converted into energy through several methods. One of the methods, direct combustion, involves burning biomass directly to produce heat. 

Another method, thermochemical conversion, involves heating biomass in the absence of oxygen to produce syngas (a mixture of hydrogen and carbon monoxide), bio-oil, and biochar. 

The biochemical conversion method utilises microorganisms to break down organic materials anaerobically, producing biogas (mainly methane) that can be used for heating or electricity generation.

The process of biomass energy production

Here are the steps involved in the production of biomass energy:

  1. Feedstock collection: Organic materials are collected from various sources such as farms, forests, and landfills.
  2. Preprocessing: This step may involve drying or grinding the biomass to prepare it for conversion.
  3. Conversion technologies: 
    • Combustion: Direct burning of biomass releases heat for electricity generation.
    • Gasification: Biomass is converted into syngas at high temperatures in a low-oxygen environment.
    • Anaerobic digestion: Organic matter is broken down by bacteria in a sealed environment, producing biogas.
  4.  Energy generation: The heat or gas produced can be used to generate electricity or fuel for vehicles.

Biomass energy statistics from across the globe  

  • Biomass accounted for approximately 5% of total U.S. energy consumption in 2023, with wood being the predominant source (The U.S. Energy Information Administration).
  • Europe wants 27% of its energy to come from renewable sources by 2030. Bioenergy has the potential to help reach this goal.
  • As of March 31, 2023, India’s biomass power potential was estimated at 28,447 MW, which accounts for approximately 1.35% of the total renewable power potential in the country. (Energy Statistics India 2024, MOSPI)
  • The Asian region is witnessing growing investments in advanced biomass technologies, including gasification and anaerobic digestion, to improve efficiency and reduce environmental impacts.

Environmental benefits of biomass energy  

Biomass energy is considered carbon-neutral because it recycles carbon dioxide absorbed by plants during their growth cycle. This process significantly reduces greenhouse gas emissions compared to fossil fuels. Moreover, utilising waste products for energy helps minimise landfill use and promotes sustainable waste management practices.
