Malaysia has a good potential in harnessing ocean thermal
energy from the Sabah Trough. The water depth at the Sabah Tough is 2900 m and the temperature is about 3 1C at the bottom
compared with 29 1C at the surface. This temperature difference
makes OTEC possible for use in Malaysia because according to the
scientific literature, an area with a 22 1C temperature difference
has the potential to generate renewable energy [53]. Recent
developments in OTEC show that ammonia is a good choice for
the organic Rankine cycle utilized in OTEC, from which a greater
output could be generated [54].
