Ocean Energy Is Vital To The Low Carbon 2.0 Energy Transition
As the world seeks out new decarbonization strategies to address the impacts of climate change, the success stories of solar and wind need to be complemented by other renewable energy technologies. One of the most promising untapped resources can be found in the ocean.
While ocean currents flow at only 15%-20% of typical wind farm wind speeds, the density of water—approximately 800 times greater than air—yields much higher energy from these flows. These marine currents can be constant currents (as with gyre boundary currents) or tidal streams, which reverse twice daily with the lunar orbit. These currents are always present, unlike intermittent wind and solar.
