“…Tidal energy as a clean and renewable energy source, of which the benefits of carbon reduction are an important part of their environmental influence. Marine renewable energy from tidal barrages is carbon-free and has the potential to make a significant contribution to energy supplies now and in the future [11]. The reduced carbon emission can be considerable, both saving money and is a move in the right direction when it comes to tackling climate change.…”

“…However, how to select the optimal one from the 426 potential barrage sites (listed in Table 1) is a daunting challenge for decision-makers (DMs). Numerous studies concerning tidal energy have been carried out in the past, mainly focusing on the following aspects: turbine technology [3][4][5][6], sediment transport simulation models [7][8][9][10] resource assessments [11][12][13], and cost-benefit analysis [14,15]. It can be seen that many scholars have paid considerable attention to tidal energy in the recent years, however, compared with the aforementioned aspects, valid researches on TPP site selection are rare.…”

Abstract:The site selection plays an important role in the entire life cycle of a tidal power plant (TPP) project. However, some problems decrease the evaluation quality of TPP site selection: (a) suitable and effective methods are scarce since the TPP site selection involves multiple forms of data; (b) there is no comprehensive evaluation index system due to the unilateralism of existing criteria. In this paper, we firstly propose a novel method based on interval number with probability distribution weighted operation and stochastic dominance degree. It takes all stakeholders' preferences into consideration and can simultaneously deal with different forms of data in the TPP site selection; then, a comprehensive evaluation index system for TPP site selection is constructed on the basis of academic literature, feasibility research reports and expert opinions in different fields. It takes the factors of construction conditions, existing policies, social impacts as well as ecological and environmental impacts which reflects the inherent characteristics of TPP site selection fully into account. Finally, a Chinese case study is given to illustrate the applicability and effectiveness of the proposed method.

“…In preceding studies, this involved the calculation of the energy output for a tidal cycle of mean tidal conditions or simulating full spring-neap cycles and extrapolating the results to the year assuming that the spring-neap simulations are representative, e.g. [2], [32]. There, the average amplitude of the simulated period was used to calculate the annual potential energy.…”

Abstract-Tidal range energy projects present an attractive means for the predictable and large-scale generation of electricity from the marine environment. In particular, proposals are under consideration in UK waters, with their feasibility currently being under high levels of scrutiny. This is due to a combination of potential environmental and socio-economic impacts that are challenging to quantify in the absence of a standardised methodology. At present, numerical models are being developed to provide robust resource/impact assessments and inform future designs. However, modelling inconsistencies in the representation of tidal power plants, operational algorithms, and turbine technology parameters can be observed in the studies to-date. This has made comparisons between proposed designs difficult to accomplish and rely upon. We present a series of models that progressively and consistently introduce spatial dimensions in resource prediction applications. The capabilities and limitations of each of these models are discussed with regard to the evaluation of energy resource and potential hydrodynamic impacts of tidal power plant proposals. Results highlight that a range of hydrodynamic scales should be considered, employing updated parametric models relating to the turbine technology capabilities. These steps will inform optimisation analyses and the robustness of tidal power plant proposals.

“…The tidal barrage were typically comprises turbines of either unidirectional or bi-directional [6]. The tidal barrages were planned to generate electric power by ebb or flood mood or can be both the ways [18]. In general, tidal barrage structure needs a very high investment cost [20] and thus, these schemes were not economically much appealing to the investor due to their delayed in time line of profit [21].…”

“…The water level would flow in and flow out through the channel by which turbine rotates as soon as the forces applied onto the turbine (example shown in figure 1) [7]. [7] The tidal barrage is a dam, which blocks the incoming and outgoing tides and then builds a water head [18]. It makes use of potential energy due to its alteration in height between high and low tides [19].…”

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.
