Investigating Techno-Economic Feasibility of Geothermal Polygeneration in Nusalaut Island, Central Maluku District, Maluku Province

Abstract

As an archipelagic country crossed by the Ring of Fire, Indonesia has significant geothermal potential, and Nusa Laut Island is one of the islands with this potential. Thus, this research was conducted to study how to utilize low-medium geothermal energy to produce the needs of the population on Nusalaut Island. The configuration of geothermal poly generation is used to produce electricity, clean water, and a cooling system to preserve marine catches. The modeling confirms that it will generate 1.9 MWe of electricity, 21.8 m3 of fresh water production/hour, and a cold storage capacity of 36 tons of fish/ day.
