NTPC disclosed accomplishment of integrating torrefied biomass co-firing up to 20 percent at the Tanda thermal facility in Uttar Pradesh. Meanwhile, NTPC Dadri initiated co-firing, blending 7-10% non-torrefied biomass with coal.
The declaration underscored the energy transition and policy research Division of NTPC Engineering’s efforts in exploring torrefied biomass usage to amplify biomass co-firing proportions sans extensive adjustments.
The milestone of co-firing 20 percent torrefied biomass at unit-four at the Tanda thermal plant in Uttar Pradesh signifies a significant stride for NTPC, epitomizing its commitment to curbing emissions from existing coal-powered assets and progressing towards net-zero emissions objectives.
Torrefied biomass, a byproduct of heating biomass minus oxygen, bears coal-like attributes, facilitating heightened co-firing rates sans substantial system overhauls. Currently, the Gross Calorific Value (GCV) and pricing of torrefied biomass pellets are on par with imported coal.
As reported by ETEnergyworld.com, NTPC’s emission reduction strategy encompasses the integration of biomass co-firing across both existing and forthcoming coal-based power plants.
Each increment in biomass co-firing holds the potential to curtail carbon emissions by a corresponding percentage. Additionally, biomass co-firing aids in mitigating air pollution arising from direct crop residue incineration in fields.
