Europe Leading Rising Wave Of Ocean Power
Turning tide for ocean power: Is marine energy coming of age?
3 August 2017 (The Cleantech Group via Hellenic Shipping News)
“Ocean energy still has a long voyage before reaching the relative level of investment and maturity of other renewables, but recent activities in the sector are hinting at promising developments and breakthroughs…There are at least four different technologies to harness the energy of the sea – ocean thermal energy, salinity gradient energy, tidal energy, and wave energy…Ocean thermal conversion exploits the difference in temperature between deep and surface waters, while salinity gradient generation converts the difference in salt concentration between fresh and saltwater…[Wave] energy converters capture energy from the motion of waves through either floating or submerged devices…[Tidal] turbines generate electricity from the tides caused by the gravitational force of the moon and can be mounted to the seabed like submarine wind turbines…Similar to offshore wind farms, the deployment of these technologies faces challenges from difficulties in grid connections, as well as the harsh (salty & stormy) and remote (underwater) environment…[A plethora of new start-ups have emerged but more] research, pilot projects and experimentation like these will still be necessary…” click here for more
