Abstract

In order to meet electricity demand, Indonesia still relies heavily on fossil fuels, resulting in significant CO₂ emissions. Among various renewable energy, biogas has emerged as a viable alternative to fossil fuel-based power generation. This study provides a comprehensive assessment of potential of available raw materials for biogas production and presents simulation results of electricity generation.

Considering geographical distribution, POME and tapioca wastewater are identified as the most promising feedstock. The simulation results indicate that based on installed capacity, POME can generate approximately 2.4 MWe, while tapioca wastewater can yield around 3.25 MWe using gas engine technology. An economic feasibility analysis for 3 MW biogas power plant utilizing 2700 tons/day of tapioca wastewater indicates IRR of 20.83 % and a payback period of 5.01 years. A 10 % change in electricity price affects IRR by approximately 3.7–4.3 %. Biogas from POME and tapioca wastewater offers strong potential for renewable electricity in Indonesia.

印度尼西亚可持续发电的沼气潜力：机会和技术经济分析

为了满足电力需求，印尼仍然严重依赖化石燃料，导致大量二氧化碳排放。在各种可再生能源中，沼气已成为化石燃料发电的可行替代品。本研究对沼气生产的可用原料潜力进行了全面评估，并给出了发电的模拟结果。考虑到地理分布，POME和木薯粉废水被认为是最有前途的原料。仿真结果表明，以装机容量为基础，POME的发电量约为2.4 MWe，而采用燃气发动机技术的木薯废水的发电量约为3.25 MWe。利用2700吨/天木薯废水的3mw沼气电厂的经济可行性分析表明，内部收益率为20.83%，投资回收期为5.01年。10%的电价变化对内部收益率的影响约为3.7% - 4.3%。从POME和木薯废水中产生的沼气为印度尼西亚的可再生电力提供了巨大的潜力。
