This paper reviews research in ocean engineering over the last 50+ years with the aim to (I)
understand the technological challenges and evolution in the field,(II) investigate whether …

Water‐current energy is an enormous and widely distributed clean energy in nature, with
different scales from large ocean flow to small local turbulence. However, few effective …

As an abundant, clean, and predictable source of renewable energy, tidal current energy
provides a cost-effective alternative to fossil fuels. Tidal current energy harvesting …

The existence of sunlight, air and other resources on earth must be used in an appropriate
way for human welfare while still protecting the environment and its living creatures. The …

Hydropower, which contributes to around 16% of global electricity and more than 72% of
renewable electricity, is expected to play an important role in the deep decarbonization of …

Tidal current turbine is one of the innovative and emerging technologies of marine
renewable energies because it offers constant and predictable energy source that can be …

Deploying triboelectric nanogenerator (TENG) units on and below the water surface has
been a conventional method for harvesting wave energy. However, this approach restricts …

Hydrokinetic energy conversion systems are the electromechanical devices that convert
kinetic energy of river streams, tidal currents, man-made water channels or waves into …

This paper synthesises published literature on run‐of‐river hydropower, highlighting its
potential to affect both the physical and ecological conditions of river systems. The paper …
