Biomass refers to organic material from plants and animals, and it is a renewable energy source. It encompasses various materials, including wood and wood waste (like branches, dead trees, and wood chips), crops and their waste by-products, animal manure, and even the organic components of municipal and industrial wastes.

\

The use of biomass for energy purposes can be particularly appealing because it makes use of materials that might otherwise go to waste. Moreover, biomass is considered a renewable resource because its supply can be replenished on a human timescale, typically through the growth of plants.

When plants grow, they absorb carbon dioxide (CO2) from the atmosphere through photosynthesis, and when biomass is burned or decomposed, this CO2 is released back into the atmosphere. Ideally, this creates a closed carbon cycle with no net increase in atmospheric CO2 levels, which is beneficial for mitigating climate change compared to fossil fuels. However, the sustainability of biomass as an energy source depends heavily on how the biomass is sourced, managed, and utilised.

The utilisation of pyrolysis for processing biomass, optimised for producing electricity and process heat, represents a significant advancement in sustainable energy technology. In this process, organic biomass is thermally decomposed in an oxygen-limited environment, producing syngas, biooil, and biochar. The primary focus here is on maximising the yield of syngas, a combustible gas that can be directly used to generate electricity via gas turbines or engines.

The syngas, rich in hydrogen and carbon monoxide, serve as a versatile and efficient fuel for power generation, contributing significantly to the base load electricity supply. Additionally, the heat generated during the pyrolysis process can be captured and utilised for industrial processes, known as process heat.
