| Summary: | The sun is one of the largest sources of energy on planet Earth, and about 70 percent
of the earth is ocean. The specific heat capacity of sea water is greater than that of
air and land, causing the heat from the sun to remain in the ocean.The final project
research aims to estimate the potential of ocean thermal energy in Indonesian
waters based on monthly simulation data for 20 years from 2000 to 2020 from a
model with a resolution of 0.083° x 0.083° called the Copernicus Marine
Environment Monitoring Service (CMEMS). The area under review extends from
9°N – 11°S and 95°E to 141°E and is then focused on the Indonesian Exclusive
Economic Zone. This research reviews the reference depth which, according to
Nihous (2007),1000 meters is the minimum depth for cold water intake with a value
of ?T > 20. The minimum depth for cold water intake in Indonesian waters is found
to be in the range of 600 meters, and the consistent depth ranges from 600 meters
to 800 meters in the Makassar Strait, the Sulawesi Sea, and the Northern Papua
Sea. The power generated at the minimum and consistent depths for cold water
intake is 154,91 GW per month, 1858,97 GW per year, and 37.179 GW over 20
years for a depth of 600 meters with a consistent area of 1.044.496 Km2. |
