“…13 Examples include distance from market, geology, bathymetry, seabed slope and stability, seabed character, protected areas, shipping lanes, subsea cables, energy storage, grid connection requirements, extreme met-ocean conditions and visual impact. 3,[46][47][48][49] Resource focused GIS tools Some GIS tools focus on little other than the renewable energy resource itself. Nevertheless, these often incorporate other interesting features such as the ability to assess technical output at a particular site of interest enabling an indication of how a renewable energy project would perform, in terms of power produced, at the specified location.…”

Accurate and up-to-date Geographic Information System (GIS) and Techno Economic (TE) tools are pertinent to helping to develop the renewable energy sector. This paper reviews the state of the art in existing GIS and TE tools for renewable energy and proposes a methodology to develop a coupled GIS-TE software tool that is geared specifically to Marine Renewable Energy (MRE) applications and bespoke to Irish and Western UK waters. Methods for approaching GIS and TE analysis within existing tools for renewable energy are presented and compared. Many existing tools of this nature have some interesting functionalities, but most are unsuitable for MRE; are limited by a lack of information on both the technology and the site; and focus solely either on GIS or TE aspects of analysis. Additionally, almost all of those with a TE focus are not open access. The proposed tool aims to incorporate increased resolution and site relevance of resource data; the most up-to-date geospatial data for site selection; and will provide site specific TE indicators and recommendations for contemporary MRE devices. The result will be the development an open-access GIS-TE software tool for MRE.

“…In order to achieve their carbon peak and neutrality goals as soon as possible, the Chinese government has formulated a series of policies to accelerate the implementation of renewable energy alternatives with a focus on supporting technological breakthroughs in the fields of renewable energy, nuclear energy, and hydrogen energy and vigorously develop clean energy such as wind power, photovoltaics, and ocean energy [3][4][5][6]. At present, ocean energy is considered as a type of clean and rich renewable energy, and technological advances in this area have increased the potential of generating power from the ocean [7][8][9][10][11][12][13]. As an ocean energy source, wave energy has received increasing attention and ocean energy development, especially in wave energy converters, has begun to show benefits.…”

“…Wave energy generators are gradually becoming valued by different developers of wave energy devices across the world in terms of their low cost, convenient laying, and high efficiency. Therefore, there many types of wave energy converters have been invented [12,[14][15][16][17][18]. The latest survey conducted by the State Oceanic Administration shows that the ocean's renewable reserve is approximately 1.58 × 10 6 MW and the explorable reserve is 4.3 × 10 5 MW in China [19][20][21].…”

The development and utilization of wave energy is inseparable from the wave energy converter, and its stability is an important condition for operation. Heave is the biggest factor affecting the stable power generation of wave energy converters. The key method to solve this problem is to install a suitable heave plate. Therefore, the design of the heave plate is particularly important. Based on a new type of horizontal rotor wave energy converter, this paper proposes three different shapes of heave plate design schemes and completes the calculation and modeling of the engineering prototype. First, the three types of heave plate devices were numerically simulated using hydrodynamic calculation software to compare their stable performances and verify the feasibility of the scheme. Subsequently, an experimental model was made according to the parameters of the engineering prototype, and a tank experiment was carried out under the same working conditions to further study the influence of the heave plate installation distance on the stability of the wave energy generator. The results showed that when the distance was between 10 mm and 20 mm, the average amplitude change was large, and when the distance was between 20 mm and 30 mm, the average amplitude change was small. Therefore, the installation distance should be between 20 mm and 30 mm. In the case of the same heave plate area and installation distance, the average amplitude of the chamfered heave plate device was smaller than the other two types, indicating that its stability was better. The optimization of the shape and installation distance of the heave plate proposed in this study has obvious effects on improving the stability of the device and provides a reference for the design of the wave energy converter device.

“…The local wave resource assessment can be based on buoy measurements, reanalysis results, and satellite altimetry data commonly through spectral analysis. See also [9][10][11][12][13][14]. Such studies are usually confined in the statistical description of particular wave spectral parameters, such as significant wave height defined as ≅ 4√ 0 ; energy period , , = ⋯ , −2, −1,0,1, ⋯ , is the − order spectral moment, ( ) is the spectral density function, and is the spectral frequency; see, e.g., [15].…”

In the context of wave resource assessment, the description of wave climate is usually confined to significant wave height and energy period. However, the accurate joint description of both linear and directional wave energy characteristics is essential for the proper and detailed optimization of wave energy converters. In this work, the joint probabilistic description of wave energy flux and wave direction is performed and evaluated. Parametric univariate models are implemented for the description of wave energy flux and wave direction. For wave energy flux, conventional, and mixture distributions are examined while for wave direction proven and efficient finite mixtures of von Mises distributions are used. The bivariate modelling is based on the implementation of the Johnson–Wehrly model. The examined models are applied on long-term measured wave data at three offshore locations in Greece and hindcast numerical wave model data at three locations in the western Mediterranean, the North Sea, and the North Atlantic Ocean. A global criterion that combines five individual goodness-of-fit criteria into a single expression is used to evaluate the performance of bivariate models. From the optimum bivariate model, the expected wave energy flux as function of wave direction and the distribution of wave energy flux for the mean and most probable wave directions are also obtained.
