Ocean Currents Energy for Electricity Generation and Its Potential in East Java Water, Indonesia

Abstract

Electrical energy is one of the vital needs of the coastal communities, especially in coastal areas that are not affordable electricity network. To meet these needs energy diversification efforts are undertaken, such as the utilization of the energy potential of ocean currents. The aim of this study was to determine the seabed morphology and properties of hydro-oceanography as a reference the exact location in the utilization of the energy of ocean currents. Location of research in the territorial waters of East Java. Research methods such as measurement of currents, tidal observation, observation of meteorological parameters and conditions of the seabed morphology and the coastal area of research. The study was conducted to estimate the potential energy of ocean currents are spatially and temporally by utilizing a hydrodynamic model simulation results and the results of current data measurement in the field, and convert them into power unit. Which will ultimately produced maps of potential energy from ocean currents of East Java waters territory. In comparison, there are several advantages of ocean current energy utilization compared to other energy generation, such as the production of electricity generated by ocean currents each year tend to be stable and more environmentally friendly because without using fuel. Potential sites for power plants in East Java waters of the ocean currents are respectively Madura Strait Region, Southern Water of East Java, and Bali Strait water.

Establishing an Agenda for Biofouling Research for the Development of the Marine Renewable Energy Industry in Indonesia

“…Based on the abundance of renewable energy resources available across the island nation of Indonesia, marine renewable energy shows promise as one of the options to be developed for provision of clean energy [2,[7][8][9][10]. There is recognised potential for marine renewable energy (MRE) to be implemented in many coastal areas of Indonesia to provide equal access to clean energy and enable coastal development that could be socially and economically beneficial for the community e.g., job creation [2].…”

“…Several studies have been carried out to explore marine energy potential throughout Indonesian waters. Hidayati et al [7] estimated the potential resource of ocean current energy in East Java waters using a hydrodynamics model simulation and field measurement validation. Based on these calculations, the most suitable locations with high ocean current energy are in Madura Strait (northern part of East Java), the Southern Waters of East Java, and Bali Strait [7].…”

Furthermore, a few other candidate sites in Indonesia waters have also been studied, including Riau Strait, Sunda Strait, Toyopakeh Strait, Lombok Strait, Alas Strait, Molo Strait, Larantuka Strait, Boleng Strait, Pantar Strait and Mansuar Strait with water depth ranging from 7 m to 150 m [8].…”

“…The potential locations having tidal current energy and wave energy resources in Indonesia are illustrated in Figure 2. [7,8,10,11]). Figure 2.…”

Assessment of Potential Marine Current Energy in the Straits of the Lesser Sunda Islands

“…An important initial step in exploring ocean energy is to characterize and to map the resources of ocean currents for generating electrical energy. The utilization of ocean currents to produce electricity, however, is still not developed favorably and need to study in more depth (Hidayati et al, 2016). Hence, site study and ocean current resources observation has been conducted by Marine Geological Institute in the selected straits of the Lesser Sunda Islands, such as Bali and East Nusa Tenggara area (Figure 1).…”
