The development of the IHL wave-current turbine to convert the ocean energy from both wave and current

Abstract

Indonesia has abundant of renewable sources of energy, among others: geothermal, solar, water, wind and marine therefore the promotion of the utilization of the renewable and sustainable energy is urgent. Since 2006 Indonesian Hydrodynamic Laboratory (IHL) BPPT has conducted research and developed a technology converts the ocean energy resources into electricity, the kinetic energy of marine current and the potential energy of wave. The prototype of marine current turbine, 2 kW and 10 kW respectively, had been installed in Larantuka Strait in 2010 and 2011 (http://www.youtube.com/user/erw4ndi). Since mostly the maximum speed of the marine current of many straits in Indonesia are in order 1.0 - 2.0 m/s, we developed the turbine prototype that can convert not only the kinetic energy of marine current but also the potential energy of the wave, called as wave-current rotor turbine, in 2013. The current usually mixes with wave height with order 0.4 - 0.8 m. A 2 kW prototype was installed under Suramadu (Surabaya - Madura) Bridge close to pier no. 56. The prototype showed a good performance especially in converting the kinetic energy of marine current. The research was continued in 2014-2016 under Ministry of Research and Technology (INSINAS RISTEK) budget scheme. Some innovations have been done to improve the performance of turbines.

Study of Supply Chain Management of Industrial Plan Manufacturing Development of Marine Power Turbine in Indonesia

“…Ai Yuningsih et al from P3GL-ESDM [4] have studied the potential of ocean currents in Larantuka Strait, East Nusa Tenggara which explained that the potential source of ocean current energy in Larantuka Strait, NTT is very potential to be used as a source of electricity generation. This supports the research report carried out by Erwandi et al from BRIN [5], which has initiated several measurements in Larantuka Strait -NTT area about the energy potential of ocean currents in the same location as a potential location for the installation of Ocean Current Turbine.Meanwhile, Yulhendri from the Center for the Study and Engineering of Marine and Fisheries Technology [6] conducted studies at different locations at western part of Indonesia, namely the Riau Archipelago. The results of the study explain that Sugi Island is the most suitable area for the implementation of ocean current power plants.…”

Experimental Study of the Influence Wave Period on the Performance Darrieus Turbine with Modification of the Blade Angle

“…So it can be seen that the Tip speed ratio (TSR) and efficiency three values of the turbine variation decrease with the increase in the wave period. There is a study that is almost the same as this study to increase the ability of vertical axis turbines by using angled blades to absorb wave energy other than marine energy in the Madura strait although with different blade types (Blade type-LHI 166) [6]. And it turns out that by using the tilt angle, the turbine can rotate if it is exposed to ocean waves even though the efficiency of the turbine test is lower than the theoretical efficiency (0.593).…”

“…A vertical axis turbine is one of the many technologies that may transform wave energy sources into electrical power. Studies by the Indonesian Hydrodynamics Laboratory on the design of a wave current rotor installed under the Suramadu Bridge in the Madura Strait indicate that the wave period affects the number of turbine revolutions [6]. Straits with weak ocean currents, usually the sea is wavy.…”

Biofouling dan Korosi pada Infrastruktur Energi Laut di Indonesia: Analisis Bibliometrik

“…Negara kepulauan Indonesia dengan sumber daya yang melimpah masih belum memanfaatkan potensi sumber daya energi terbarukan dari laut dengan optimal, mengingat hingga saat ini belum ada kapasitas pembangkit listrik energi laut yang terpasang di perairan tropis Indonesia. Beberapa penelitian yang telah dilakukan lebih banyak berfokus pada kajian potensi sumber daya (resources assessment) [12], pemodelan (modelling) [13,14], dan peningkatan kinerja komponen pembangkit, seperti turbin [15], osilasi pendulum [16] Beberapa peneliti telah melakukan kajian dampak biofouling dan korosi pada infrastruktur energi laut dan offshore wind di perairan beriklim sedang (temperate waters) [7][8][9]19]. Kajian yang terbaru di perairan beriklim sedang Eropa telah menghimpun database tentang organisme-organisme laut yang paling dominan menyebabkan terjadinya biofouling pada perangkat pembangkit energi laut [19].…”
