OTEC in Indonesia

Indonesia is the biggest of archipelago country that has many seas could be developing ocean thermal energy conversion (OTEC) technology. This technology in The Institute of Ocean Energy Saga University (IOES) Japan already developed to create chance to produce electricity. Indonesia also makes this in Mamuju west Celebes for electricity and hydrogen generation fit and properties test.
The differential temperature between sea level and deep sea only need 15oC and the deep around 500m to 1500m.




Ammonia as a fluid work at 24oC can be boil and creating a pressure to move a turbine. The OTEC output is not only produce electric power, but it can be improve to produce hydrogen gas from electrolysis process.


History of OTEC
In 1881, Jacques Arsene d’Arsonval, a French physicist proposed tapping the thermal energy of the ocean. It was d’Arsonval’s student, Deorge Claude who actuallt built the first OTEC plant in Cuba 1930. The system generated 22kW of electricity with a low pressure turbine.

Hydrogen Production
Hydrogen can produce via electrolysis using electric generated by OTEC process. The steam generated can used as a relatively pure medium for electrolysis with electrolyte compounds added to improve the overall efficiency.

Desalinated Water.
Desalinated water can be produced in open or hybrid cycle plants using surface condensers. In a surface condenser, the spent steam is condensed by indirect contact with the cold sea water. This condensate is relatively free of impurities and can collected and dispense to local communities where supplies of natural fresh water for agriculture or drinking are limited. System analysis indicates that a 2 MW plant could produce about 4300 meter cube of desalinated water each day (Block and Lalezuela 1985)
