Singapore test runs first tidal turbine system

Intends to test feasibility of using tidal energy to generate electricity.

A research group at Nanyang Technological University has tested Singapore's first tidal turbine system. Built at the site of Sentosa Boardwalk, the tidal turbine system consists of two low-flow turbines mounted on the test bed, which are optimized for local conditions.

The two turbines can draw energy from tidal currents to generate up to 1,000 watts of energy per hour combined, enough to power 70 fluorescent light bulbs. Researchers said the energy generated during the test will be used to power lights at the Sentosa Boardwalk Turbine Exhibit.

The new tidal turbine test bed was designed, built and installed by NTU engineers from the Energy Research Institute in collaboration with the Sentosa Development Corporation. Sentosa Boardwalk is a bridge connecting the main island of Singapore and Sentosa Island.

NTU said that compared to typical turbines, these specially designed prototypes are able to work at higher efficiency despite low water speeds similar to those found in Singapore's waters.

Tidal energy’s key advantage as a renewable energy source is that tidal cycles are predictable, unlike conventional wind and solar energy, which are highly susceptible to weather fluctuations.
