The Role Of Biomass Energy In Achieving Net Zero Emissions


The world leaders have committed to achieving net-zero greenhouse gas emissions by mid-century as a critical step towards limiting global warming. Achieving net-zero will require a combination of measures across various sectors including energy, transportation, and industrial sectors. One of the critical measures that can help achieve net-zero emissions is the use of biomass energy.

What is Biomass Energy?

Biomass energy is energy derived from organic matter such as plants, trees, and agricultural and municipal waste. It can be converted into various forms of energy such as electricity, heat, and biofuels.

Why is Biomass Energy important?

Biomass energy has several advantages that make it a crucial player in achieving net-zero emissions:

Carbon Neutrality

Biomass energy is carbon-neutral, meaning that as trees and plants grow, they absorb carbon dioxide (CO2) from the atmosphere. When the biomass is used for energy, it releases an equivalent amount of CO2 into the atmosphere. Therefore, the net carbon emissions are zero, making it an ideal alternative to fossil fuels.


Biomass energy is a renewable energy source. Trees and plants can be regrown, and agricultural and municipal waste will continually be produced, providing a sustainable source of energy.

Reduces Waste

Biomass energy reduces waste by utilizing agricultural waste, forestry waste, and municipal waste that would otherwise end up in landfills, contributing to environmental problems such as pollution and methane emissions.

Reduces Reliance on Fossil Fuels

Biomass energy can help reduce our reliance on fossil fuels, making it a crucial step towards achieving net-zero emissions.

Biomass Energy Technologies

There are three main technologies used to convert biomass into energy:


Biomass is burned to produce steam, which is then used to generate electricity or heat. Combustion systems are commonly used in power plants and industrial applications.


Biomass is converted into a gas, known as syngas, through a process called gasification. The syngas is then used in a gas turbine to generate electricity or heat.

Anaerobic Digestion

Organic matter is broken down by bacteria under anaerobic conditions, producing biogas that can be used for heat or electricity generation.

Applications of Biomass Energy

Biomass energy can be used in various sectors, including:

Electricity Generation

Biomass power plants generate electricity by burning biomass. According to the International Renewable Energy Agency (IRENA), biomass electricity production was 135 GW in 2020, accounting for 2% of global electricity generation.


Biomass energy is used for space and water heating in residential, commercial, and industrial buildings.


Biomass can be converted into biofuels such as ethanol, biodiesel, and renewable natural gas, which can be used as transportation fuels.

Challenges for Biomass Energy

Although biomass energy has several advantages, there are also challenges that need to be addressed to make it a viable option for achieving net-zero emissions:

Land Use

Biomass production requires land, which can compete with food production or natural habitats.


Biomass production needs to be sustainable to ensure that the biomass feedstock is regenerative and does not have negative environmental impacts, such as deforestation.


While biomass energy is carbon-neutral in theory, there are emissions associated with the production, transportation, and conversion of biomass into energy.


Biomass energy is a promising and versatile option in the effort to achieve net-zero emissions. It is a renewable, carbon-neutral, and waste-reducing source of energy that can reduce our reliance on fossil fuels. Although there are challenges that need to be addressed, biomass energy can play a significant role in reducing global greenhouse gas emissions.
