Abstract. OTEC or Ocean Thermal Energy Conversion is one of an alternative<br />
ocean renewable enrgy using the temperature/thermal difference between wamer sea<br />
surface and cooler deep waters to run the turbine and electric generator. This<br />
technology has been implemented in some first world countries at the prototype scale<br />
to produce up to 1MWe, but considerably less efficient for the small scale prototype.<br />
Through various research cruises, BPPT has collected a lot of vertical/water column<br />
profiles of temperature all around Indonesia seas. Data analyses show that some<br />
areas meet the condition of 20⁰C temperature difference between sea surface and<br />
deep waters down to 700-800m located relatively close less than 10k to the nearest<br />
islands. Considering the available natural resources and steep marine continent<br />
geomorphology, Indonesia seas store a huge potential of natural resources, but the<br />
most recent available technologies limit to estimate viable resources to implement<br />
the OTEC technology at the pra-commercial scale. Implementation OTEC<br />
technology in Indonesia must remain depend on the mature of this technology in the<br />
world.<br />
