The vertical temperature distribution in the open ocean can be represented as two layers separated by an interface. The upper layer is warmed by the sun and mixed to depths of about 100 m by wave motion. The bottom layer consists of colder water formed at high latitudes. The interface or thermocline is sometimes marked by an abrupt change in temperature but more often the change is gradual.…

Marine hydrokinetic (MHK ) energy is clean, renewable, and available worldwide. It comes in two forms: vertical in waves and horizontal in currents, tides, and rivers. Apart from a few major ocean currents, most of the ocean currents have flow speeds less than 3 kn and most rivers have speeds less than 2 kn, making harvesting of their MHK energy by steady-lift technologies (turbines)…

Ocean thermal energy conversion (OTEC ) utilizes the thermal gradient available in the ocean to operate a heat engine to produce work output. Even though the concept is simple and old for almost one century, during last three decades, it has gained momentum due to worldwide search for a clean, continuous energy source to replace the fossil fuels. There are technological hurdles to overcome to…

The value of investments in renewable energy sources (RES) has increased rapidly over the last decade and in the last five years it outstripped that in fossil fuel generation. In Europe (EU) this was due to the combination of a strong: i) decrease of the Levelized Cost of Energy (LCoE) from RES, ii) increase of the reliability of renewable energy (RE) technologies, iii) policy pressure to…

Woolf et al.
Increasing interest is apparent in marine energy resources, particularly tidal and wave. Some TeraWatts of energy propagate from the world’s oceans to its marginal seas in the form of surface waves (≈ 2 TW) and tides (≅ 2.6 TW) where that energy is naturally dissipated. The seas and coastlines around the UK and its neighbours are notable for dissipating a significant fraction of the global…

Zhaoqing and Taiping. W.
Over the last decade, many studies have been conducted to estimate the upper limit of the theoretical resource of tidal stream energy and its associated influence on volume flux. However, studies aimed at evaluating the effects of tidal energy extraction on water exchange and transport timescale have been limited. This chapter provides a detailed review of different methods—from analytical…
