Economic Feasibility Study of Syngas-Derived Garden Waste Biomass as Liquified Petroleum Gas Substitute in Indonesia: A Case Study for 1-Megawatt Updraft Fixed Bed Gasifier

Abstract

The price of international Liquified Petroleum Gas (LPG) has suffered in Indonesia, leading to its replacement with renewable ones, such as syngas. This study focuses on the techno-economic analysis of the 1-megawatt updraft fixed bed gasifier using a garden waste biomass. Three syngas price scenarios are considered, and the weighted performance index ranks the scenario and performs a sensitivity analysis on the best rank. The scenario of the 40% syngas price being less than the retail non-subsidized price fits and offers attractive economic feasibility to investors, balancing consumers' purchasing ability and government subsidies.
