What's Ocean Energy
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．
