Biomass Value Improvement and Techno-Economic Analytics in Power Plant

Abstract

The 23% NRE energy mix in 2025 is getting closer. An alternative fuel is needed to support the energy mix program and can improve power plant performance. Sawdust, which is the residual biomass from the furniture industry in Indonesia, has good potential to be reused as an alternative fuel and part of renewable energy. This research investigates further to improve the value of sawdust into biocharcoal as renewable energy cofiring that has a higher calorific value by pyrolysis process, and the optimum composition as a fuel mix component in coal power plant. The analysis process uses tabulation and has been validated by using SOLVER to make the cofiring composition so as to get optimization in order to get the most efficient fuel cost (cents/kWh) by setting up the calorific value target. In the economical sensitivity area, coal price has more affecting than biocharcoal price.
