“…Maximum current and maximum power density approached 1.8 m/s and 1.0 kW/m 2 , respectively. For the 16-day period considered, the energy density, or energy per square meter of turbine aperture is shown in Figure 8 The annual energy density per turbine in the Penghu Channel is less than that in the Ria de Muros (Spain) [5], but higher than that in the Severn Estuary (UK) [8]. …”

“…The kinetic energy of the flow is used, whereas tidal barrages use potential energy. Tidal current energy has several advantages, including the high predictability of tides, the high power density of water flow, the development of turbine technology, the lower investment relative to barrage structures, and the lower ecological impact compared with large hydraulic structures [5].…”

“…Sutherland et al [7] adopted a two-dimensional finite element model (TIDE2D) to evaluate the maximum tidal power potential of the Johnstone Strait, BC, Canada. Carballo et al [5] applied a two-dimensional horizontal finite element model to evaluate the tidal stream energy resources in the Ria de Muros, which is in the northwestern coast of Spain. Xia et al [8] used a refined depth-integrated two-dimensional hydrodynamic model to assess the potential tidal stream energy resources with and without the Severn Barrage in the Severn Estuary, UK.…”

Tidal stream speeds in straits are accelerated because of geographic and bathymetric features. For instance, narrow channels and shallows can cause high tidal stream energy. In this study, water level and tidal current were simulated using a three-dimensional semi-implicit Eulerian-Lagrangian finite-element model to investigate the complex tidal characteristics in the Taiwan Strait and to determine potential locations for harnessing tidal stream energy. The model was driven by nine tidal components (M 2 , S 2 , N 2 , K 2 , K 1 , O 1 , P 1 , Q 1 , and M 4 ) at open boundaries. The modeling results were validated with the measured data, including water level and tidal current. Through the model simulations, we found that the highest tidal currents occurred at the Penghu Channel in the Taiwan Strait. The Penghu Channel is an appropriate location for the deployment of a tidal turbine array because of its deep and flat bathymetry. The impacts of energy extraction on hydrodynamics were assessed by considering the momentum sink approach. The simulated results indicate that only minimal impacts would occur on water level and tidal current in the Taiwan Strait if a turbine array (55 turbines) was installed in the Penghu Channel.

“…Till the year 1990, for utilization of tidal power required a basin with an appropriate water level variation as comparative to the outside body of water, as an existing turbine required a significant hydraulic head to work [12]. The tidal energy involved ocean waters at high tide and low tide, although its waves show the movement of its flow horizontally [7].…”

Abstract. Tidal energy is one of the best predictable and reliable source of renewable energy. Therefore, this paper aims to map extractable tidal energy, and to determine potential locations to generate electricity from tidal power along the coastline of Sabah and Sarawak states of Malaysia. The data was obtained from Sarawak Marine Department, and analyzed by using ArcGIS version 10.3. There are two potential locations, namely Tawau in Sabah, and Pending in Sarawak, where 67.0kW and 115.4kW of optimum power generated were obtained respectively.

“…These resource assessments have been mainly carried out by means of hydrodynamic numerical models validated against field measurements [11]. However, the approaches used vary significantly for different parameters, such as the time scale of the assessments, the effects derived from the wave-current interaction, the inclusion of the TEC operation in the modelling strategy for a correct estimation of the tidal resource and performance of different TEC technologies and some aspects related to the economic point of view.…”

a b s t r a c tOver the next decades, tidal stream energy aims to become a fully commercially viable energy source. For this purpose, complete knowledge regarding tidal stream resource assessment is essential. In this context, the International Electrotechnical Commission has developed a technical standard for the assessment of the tidal stream resource, ''IEC 62600-201 TS: Marine energy -Wave, tidal and other water current converters -Part 201: Tidal energy resource assessment and characterisation", offering a vast set of recommendations in the fields of data collection, numerical modelling, data analysis and reporting of the results with the purpose of standardising tidal stream resource characterisation. The standard divides resource assessments into two different classes: feasibility and layout design. The model setup procedure (mesh resolution, boundary conditions) and the computational effort required vary significantly from one class to another. For these reasons, the objective of the present work is to explore the proposed standard using the Orkney Region (N Scotland) as a case study. Overall, it was found that the standard works well, offering a detailed characterisation of the tidal resource; however, in order to improve its manageability, some aspects related to the grid resolution requirements and the approach to model a tidal energy converter could be revisited for future editions.
