    A NEW LOOK AT THE WORLD’S OCEAN ENERGIES

    IRENA Evaluates Four Ocean Energy Technologies

    June 2014 (International Institute for Sustainable Development)

    “The International Renewable Energy Agency (IRENA) has published a series of technology papers exploring the potential for [four ocean energy technologies]: tidal energy; wave energy; ocean thermal energy conversion; and salinity gradient energy…[T]he potential of ocean energy is estimated at 100-400% of global electricity demand…[but] is expected to continue to be small in the short to medium terms…IRENA estimates the total technically harvestable tidal energy potential located near coasts at one terawatt…[D]espite over 100 pilot and demonstration [wave enery] projects over the world, only a handful of technologies are close to commercialization…[and] estimates for levelized cost of electricity in 10 MW demonstration projects is high, at €330-360/MWh…[O]cean thermal energy conversion as having the highest potential of all ocean energy technologies… 98 countries and territories have been identified as having viable [with zero impact] resources…Salinity gradient power, created from the difference in salt concentration between fresh and salt water, currently at pilot stage, has an estimated total technical potential of 647 GW, but is facing funding issues…” click here for more
