Ocean energy
The term ocean energy encompasses various forms of mechanical, thermal and physical-chemical energy contained in the water masses of the world's oceans . Their technical use for energy generation is still in its infancy, but ocean energy - assuming appropriate technical progress - could make a significant contribution to the energy supply of mankind in the future.
Technologies for harnessing ocean energy include:
- Tidal power plants
- Ocean current power plants
- Marine thermal power plants
- Osmotic power plants
- Wave energy
- Wave power plant
The largest heat pump system that u. a. Uses seawater, is located in Stockholm as of 2016 . Using an electrical output of 200 MW, the system supplies a district heating network with a heating output of 660 MW.
Offshore wind farms and floating wind turbines , which are classified in the wind energy category, are usually not counted as marine energy . In addition, seawater, like water from other bodies of water, can serve as a heat source for heat pumps .
