“…Information on ESI for sector III is relevant. However, it is necessary to know the ESI for each municipality whether the installation of tidal dams is to be considered since these enterprises occur in specific areas 1,80 . Therefore, ESI of each municipality was calculated to determine their profile with regards to the capacity of installing tidal dams, as Figure 5 demonstrates.…”

“…Tidal energy is a technology used in coastal areas to produce clean electricity and minimize carbon dioxide (CO 2 ) emissions to the atmosphere. The driving force of this renewable source originates from astronomical phenomena produced by the movement of the moon and the sun in relation to the earth 1 . Various techniques for energy exploitation can be used to convert mechanical tidal energy into electricity such as wave absorption floats, hydrokinetic turbines taking advantage of tidal currents, and storage dams that employ potential energy from tidal cyclic behavior 2 …”

This study proposed an environmental sustainability index (ESI) to aid the identification of suitable areas for the installation of tidal power plants (TPPs) in coastal areas. Geographic Information System (GIS) and multicriteria analysis (MCA) were integrated to construct the proposed method. ESI consisted of a subindex of environmental fragility (EFI) with six components (geology, geomorphology, vegetation, slope, pedology, and land use), selected from the scientific literature. Therefore, the method serves as a guiding tool for coastal regions without existing information on the environmental impacts generated by this type of energy system. A consultation process with experts, the Delphi method, was conducted to assign weights to the components and subcomponents of the proposed ESI method. The study tested the method on a case study at the sector III of the coastal zone of the state of Pará (CZP), Brazil. The simulations considered scenarios with the installation of TPP of different scales. Scores close to 3 were considered less fragile sites in the ESI. The municipalities with the best ESI performance were São Sebastião da Boa Vista for scenarios I (2.7721) and II (2.126), and Soure for scenario III (1.9908). Moreover, ESI analysis revealed that small tidal dams for sector III are more feasible than medium and large dams. The use of GIS integrated with MCA provided a useful tool to analyze different parameters and visualize areas with the greatest environmental potential. There are challenges associated with complexity of MCA, dependency on expert's opinion, and subjectivity of the weighting system. In addition, limited data is available for the region, which hindered us to explore more fragility parameters.

“…From the perspective of transmission efficiency, most marine renewable energy power stations are close to the load center; thus, it is unnecessary to build high‐voltage lines for long‐distance power transmission with a high cost. From the perspective of added economic benefits, marine renewable power stations, especially tidal power stations, are capable of stimulating the development of tourism, aquaculture, reclamation of farmland and transportation industry in the surrounding areas (Figure ).…”

Summary The rapid development of China's economy cannot be separated from the massive consumption of fossil fuel. However, potential risks such as the extreme shortage of fossil fuel and the resulting environmental problems are becoming more and more prominent. As a substitution for fossil fuel, renewable energy is playing an increasingly important role in the energy structure adjustment. As a special type of renewable energy, marine renewable energy has been paid much attention by China's government and scientific researchers because of its properties such as cleanness, environmental protection and large reserves. Under the background of energy structure adjustment and electricity market reform in China, the marine renewable energy power market has a bright future. Through querying an amount of literature and information, this paper makes a strategic analysis based on the understanding of the resource endowment, the current industrial status, and policy environment. Then, the PEST‐SWOT strategy analysis model was adopted to analyze the internalities (strengths and weaknesses) and the externalities (opportunities and threats) of the factors affecting the development of marine renewable energy power industry. Then, some countermeasures from the four angles of strategic positioning, institutional arrangement, environmental education, and technical support are proposed to address the weaknesses and threats. Through the research, some conclusions and policy proposals are finally put forward to promote the sustainable development of the industry.

“…Descriptions of thirteen multi-basin concepts were summarised by Bernshtein [23], drawing information from ideas since the 19 th century in an attempt to provide baseline power. Only a single small-scale scheme of this type has been recorded: the Haishan tidal power plant in China, featuring a capacity of 0.25MW since 1975 [24,25]. Linked-basin tidal power systems have been considered for other sites such as the Bay of Fundy [26] and as part of the Severn Estuary tidal power feasibility studies in the UK.…”

On the potential of linked-basin tidal power plants: An operational and coastal modelling assessment

et al. 2020

Single-basin tidal range power plants have the advantage of predictable energy outputs, but feature non-generation periods in every tidal cycle. Linkedbasin tidal power systems can reduce this variability and consistently generate power. However, as a concept the latter are under-studied with limited information on their performance relative to single-basin designs. In addressing this, we outline the basic principles of linked-basin power plant operation and report results from their numerical simulation. Tidal range energy operational models are applied to gauge their capabilities relative to conventional, single-basin tidal power plants. A coastal ocean model (Thetis) is then refined with linked-basin modelling capabilities. Simulations demonstrate that linked-basin systems can reduce non-generation periods at the expense of the extractable energy output relative to conventional tidal lagoons and barrages. As an example, a hypothetical case is considered for a site in the Severn Estuary, UK. The linked-basin system is seen to generate energy 80-100% of the time over a spring-neap cycle, but harnesses at best ≈ 30% of the energy of an equivalent-area single-basin design.
