Sustainability Analysis of Renewable Energy Technologies on the Island of Batanta, Papua, Indonesia

Abstract

In this study, sustainable renewable energy technology was investigated for a remote island of Batanta (0.8647° S, 130.6494° E) near Papua island in the eastern part of Indonesia. The 453-km2 island is occupied by several tribes totaling a 2500 population with limited access to power lines. The island is surrounded by shallow oceans (10-30 m depth) with endangered coral and protected marine biodiversity. Oil spills during sea transportation and coral damage by large ships limit the energy supply to the island. Solar photovoltaic panels demonstrate the most feasible option for the electricity supply. However, other possible solutions are required to anticipate population growth. Alternative energy suppliers studied include hydrokinetic power, wind turbines, and a solar chimney. The water power can be made possible by creating a rain collector at the highest part of the island (1184 m) and employing a water turbine to generate electricity. The low-speed wind (around 2 m/s) of this island require wind turbines with a large diameter. However, the transportation and construction cost can be high. The design of a solar chimney electric generator is considered due to its zero emission along with a possible combination of desalination technology.
