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.
