Abstract

Co-firing is the efforts to reduce the use of fossil fuel (coal) form steam power plant. Adding biomass as a partial fuel to the boiler to reduce coal consumption thereby reducing carbon dioxide emissions which can have an impact on the greenhouse effect. This co-firing study implemented 5-20% palm kernel shells. The emission has decreased very significantly in the use of biomass by 20%, Carbon dioxide (CO2) from 7% to 0.9% and carbon monoxide (CO) from 759 Mg/Nm3 to 105 Mg/Nm3. Slagging index during is still within safe limits. Fouling index when coal firing and co-firings 5%, 15% and 20% are in the high category, while co-firing is 10% in the severe category. Base to acid ratio during co-firing test 5%, 10% and 15% in the high/severe category, while co-firing is 20% is still within safe limits. The potential for corrosion due to the presence of chlorine is Cl-induced active oxidation minor. The toxic properties samples obtained from various co-firings are still in safe condition and meet quality standards.

Abstract

Climate change is a global challenge that demands collective efforts, including from Indonesia, which aims to reduce greenhouse gas emissions by 31.89% through domestic efforts and 43.20% with international support. As part of a state-owned company, PLN contributes to this effort by integrating hydrogen business development into its strategic program. PLTU Banten 2 Labuan has a hydrogen plant with the potential to produce excess hydrogen for economic use. This research simulates three hydrogen production schemes to optimize performance and cost efficiency. The analysis reveals significant differences in terms of CAPEX, OPEX, LCOH, NPV, PI, IRR, DPP, and carbon emissions. Scheme 4, despite having the lowest emissions and OPEX, has very high CAPEX, with the highest LCOH of 7.41 USD/kg and poor financial performance (negative NPV of -217,908.33 USD, IRR of 3.62%, and PI of 0.59). Scheme 2, with the lowest LCOH of 3.79 USD/kg, is attractive but results in high carbon emissions (318,864 kg CO₂e). Scheme 5, with moderate CAPEX and LCOH of 4.03 USD/kg, performs best overall, showing positive financial indicators NPV of 163,593.97 USD, PI of 3.14, IRR of 32.62%, and a short DPP of 3.2 years. Scheme 5 is the most optimal and recommended for further implementation.
