A key factor in the uptake of ocean energy will be predictability of produced energy (or water), as this will affect grid connections and the market price for electricity sold into local markets. Ocean currents, osmotic power, OTEC and submarine geothermal energy could potentially produce continuous, i.e., baseload, electricity, whilst tidal currents are forecastable for periods of days (with some modification due to weather). Even wave energy can be predicted 1-2 days in advance. All forms of ocean energy are less variable than wind energy.
