Frequently Asked Questions

It depends on the coal grade. For Bituminous coal (GCV 6,000 kcal/kg), approximately 1.20 tonnes of biomass pellets (GCV 3,600 kcal/kg) are needed for equivalent energy output. Our calculator automatically adjusts for different coal types and grades.

For 7% co-firing at a 100 MW plant, approximately 500-600 tonnes of storage capacity is needed. Pellets must be stored in covered silos or warehouses to protect from moisture.

BIS 17062 certification is mandatory for industrial biomass pellets in India. This ensures minimum calorific value, maximum ash content, and consistent moisture levels.

Yes, most power plants start with 1-2% co-firing to test pellet compatibility with their boilers before scaling up to the mandated 7% co-firing level.

Carbon credits are claimed through Clean Development Mechanism (CDM) registration. Credits are tradeable on the India Carbon Exchange at rates of ₹500-800 per tonne CO₂ equivalent.

Biomass pellet ash contains high potassium and phosphorus content, making it valuable for potash fertilizer production. 95% of biomass ash can be sold to fertilizer manufacturers.
