What's Ocean Energy ?

Ocean stores vast energy resources in various forms. Effective recovery of energy-generating substances will produce environmentally-friendly energy, which will be replaced by fossil fuel. Practical application of ocean energy is highly expected to overcome energy and environmental issues.
 

Examples of ocean energy

Ocean thermal energy conversion Power generation using temperature difference between surface and deep seawater
Wave energy conversion Power generation using energy stored in waves
Marine current power generation Power generation using kinetic energy of marine current
Offshore wind power generation Power generation using wind on ocean
Tidal power generation Power generation using difference between rising and falling tide
Ocean salinity gradient power generation Power generation using salinity difference in seawater
Recovery of rare metals from seawater Recovery of rare metals such as lithium and uranium from seawater
Deep seawater Use of deep seawater at a depth of around 1,000 meters deep for processing foods, manufacture of cosmetics, mariculture, and other purposes

Study on Hydrogen energy is conducted as a secondary energy of ocean energy.

Hydrogen energy Hydrogen generation by electrolysis using pure water produced by desalination and electricity generated by ocean thermal energy conversion

The study on heat exchanger as a principal machine of OTEC are conducted. 

Heat exchanger  The thermal energy in seawater are extracted by heat exchanger 

Institute of Ocean Energy, Saga University (IOES) promotes the research of ocean thermal energy conversion, wave energy conversion, marine current power generation,  Offshore wind power generation, hydrogen energy and heat exchanger.
