A method for the spatial targeting of tidal stream energy policies
International Marine Energy Journal, 2018 Policy making is called to play a decisive role in the commercialisation of tidal stream energy projects. For they are site-specific, spatial targeting of policies is needed, so that tidal stream regulations (financial supporting mechanisms, consenting ...

Spatio-temporal variability of tidal-stream energy in north-western Europe. [PDF]
Philos Trans A Math Phys Eng Sci, 2020 Initial selection of tidal stream energy sites is primarily based on identifying areas with the maximum current speeds. However, optimal design and deployment of turbines requires detailed investigations of the temporal variability of the available resource, focusing on areas with reduced variability, and hence the potential for more ...

Life-stage and environmental influences on the recruitment of African freshwater eels into the uThukela River, South Africa. [PDF]
J Fish BiolAbstract Anguillid eel recruitment into east‐flowing rivers along the east coast of Africa is poorly understood. The few harvest records of anguillid eels from South Africa have highlighted anthropogenically derived environmental stressors as risks for further decline.

Tidal stream energy potential in the Shannon Estuary
Renewable Energy, 2022 The tidal and river in-stream energy resource in the Shannon Estuary (W Ireland) is investigated using of high-resolution numerical modelling and spatial analysis. Although freshwater discharges are large, their influence on the available resource is found to be all but negligible, the tide being the main driver of estuarine circulation.

Procedia Engineering, 2015 AbstractIn the recent decades, many efforts have been made by the coastal scientists and engineers for the explosion of tidal stream energy in China, as tidal stream energy is considered as one of most promising resources of marine renewable energy.

Tidal-stream power assessment—A novel modelling approach
Energy Reports, 2020 An alternative approach for simulating turbine array energy capture, momentum sink-TOC, was developed to improve conventional methodologies for assessing tidal-stream energy resource.

Galilean Equivalence for Galactic Dark Matter [PDF]
, 2006 Satellite galaxies are tidally disrupted as they orbit the Milky Way. If dark matter (DM) experiences a stronger self-attraction than baryons, stars will preferentially gain rather than lose energy during tidal disruption, leading to an enhancement in ...

Tidal energy extraction modifies tidal asymmetry and transport in a shallow, well-mixed estuary
Frontiers in Marine Science, 2023 Tidal energy extraction is increasingly being studied as a potential renewable energy resource in estuaries worldwide. Although it is understood that energy extraction via tidal stream turbines can modify currents and transport within estuaries, it is ...

Capital costs in tidal stream energy projects - A spatial approach [PDF]
, 2016 Tidal stream energy projects involve high amounts of capital, for which ex-ante economic assessments are crucial. Unfortunately, the existing models to estimate the capital costs of a tidal stream energy project are often oversimplified.

Journal of Marine Science and Engineering, 2019 Estimating the energy potential of tidal stream site is a key feature for tidal energy system deployment. This paper aims to compare two methods of prediction of tidal current velocities. The first one is based on the use of a fully three-dimensional (3D)
