Levelised Cost of Energy for High Tip-Speed Ratio Tidal Turbines Operating in Less Energetic Flows

Chemical Engineering Transactions, 2023
The development of the tidal stream industry has been steady over the years. However, this growth is concentrated in areas of the world where the current magnitudes are high, mostly in the northern parts of the UK.

The influence of waves on morphodynamic impacts of energy extraction at a tidal stream turbine site in the Pentland Firth [PDF]

, 2018
Extraction of energy from tidal streams has the potential to impact on the morphodynamics of areas such as sub-tidal sandbanks via alteration of hydrodynamics. Marine sediment transport is forced by both wave and tidal currents. Past work on tidal stream

Substantial Research Secures the Blue Future for our Blue Plant

Renewable Energy and Sustainable Development, 2016
Earth, the blue planet, is our home, and seas and oceans cover more than 70% of its surface. As the earth’s population rapidly increases and available resources decrease, seas and oceans can play a key role in assuring the long-term survival of humankind.

Development of a contra-rotating tidal current turbine and analysis of performance [PDF]

, 2007
A contra-rotating marine current turbine has a number of attractive features: nearzero reactive torque on the support structure, near-zero swirl in the wake, and high relative inter-rotor rotational speeds.

Design, commissioning and performance of a device to vary the turbulence in a recirculating flume

, 2013
Ambient turbulent flow structures are one of the key drivers that will determine the rate of wake recovery downstream of tidal turbines. For second and third generation arrays or farms such a parameter is critical for the determination of inter-device ...
