India's bioenergy initiatives toward Net Zero

Bioenergy, derived from organic materials like agricultural residues, forestry waste, and dedicated energy crops, is a versatile renewable energy form. It can replace fossil fuels in power generation, heating, and transportation fuels, thus directly cutting down greenhouse gas (GHG) emissions.

The Carbon Negative Potential

Bioenergy has the potential to be carbon neutral because the CO2 released during biomass combustion was originally captured from the atmosphere during plant growth. When combined with carbon capture and storage (CCS), bioenergy can become carbon negative (BECCS - Bioenergy with Carbon Capture and Storage), removing CO2 from the atmosphere and aiding in net negative emissions crucial for net zero goals.

Integration with Circular Economy

Using waste biomass (like agricultural residues, municipal solid waste, and industrial byproducts) for bioenergy supports circular economy principles by reducing waste and turning it into useful energy, further lowering the carbon footprint.

Challenges in Sustainability and Land Use

Sourcing biomass sustainably is critical. Poorly managed bioenergy initiatives risk deforestation, biodiversity loss, and competition with food production. To truly support net zero, bioenergy must prioritise sustainable feedstocks and avoid indirect land-use changes that could increase emissions.

Complement to Intermittent Renewables

Bioenergy provides dispatchable power— meaning it can be stored and used on demand— offering a critical complement to intermittent renewables like solar and wind. This flexibility supports grid stability, helping maintain a reliable, low-carbon energy system.

Technological Innovations

Advances in bioenergy technologies—such as second and third-generation biofuels (e.g., algaebased fuels), anaerobic digestion, and improved gasification—can increase efficiency and reduce environmental impacts. Supporting R&D is essential for scalable, cost-effective bioenergy solutions.
