India has been severely lagging in ensuring that at least 5% of coal used in thermal plants was mixed with biomass despite guidelines mandating them to do so. This recalcitrance by power manufacturers has prompted the Power Ministry to consider cutting coal supply to non-compliant plants, it emerged from the proceedings of an inter-ministerial meeting of the Environment, Agriculture and Power Ministries on Monday.
The Power Ministry in October 2021 had decreed that all thermal power plants ensure 5% compliance by October 2022. Biomass pellets have the same calorific value as coal and mixing them with coal saves consumption as well as reportedly cuts emissions.
The meeting to review progress of biomass co-firing in thermal power plants was held in New Delhi to prepare for the coming post-monsoon season that saw farm fires in north India and worsening air pollution. Biomass from stubble, which is often burned by farmers in open fields, can be used in coal plants to reduce pollution.
