Abstract:The South China Sea is a major shipping hub between the West Pacific and Indian Oceans. In this region, the demand for energy is enormous, both for residents' daily lives and for economic development. Wave energy and wind energy are two major clean and low-cost ocean sources of renewable energy. The reasonable development and utilization of these energy sources can provide a stable energy supply for coastal cities and remote islands of China. Before wave energy and wind energy development, however, we must assess the potential of each of these sources. Based on high-resolution and high-accuracy wave field data and wind field data obtained by ERA-Interim reanalysis for the recent 38-year period from 1979-2016, the joint development potential of wave energy and wind energy was assessed in detail for offshore and nearshore areas in the South China Sea. Based on potential installed capacity, the results revealed three promising areas for the joint development of nearshore wave energy and wind energy, including the Taiwan Strait, Luzon Strait and the sea southeast of the Indo-China Peninsula. For these three dominant areas (key stations), the directionality of wave energy and wind energy propagation were good in various seasons; the dominant wave conditions and the dominant wind conditions were the same, which is advantageous for the joint development of wave and wind energy. Existing well-known wave energy converters (WECs) are not suitable for wave energy development in the areas of interest. Therefore, we must consider the distributions of wave conditions and develop more suitable WECs for these areas. The economic and environmental benefits of the joint development of wave and wind energy are high in these promising areas. The results described in this paper can provide references for the joint development of wave and wind energy in the South China Sea.

“…We must estimate the energy production of some proposed state of the art WECs to develop a pilot plant of wave energy in these key locations, which may be more useful for the practical development of wave energy. In this paper, we refer to the work of Vannucchi and Cappietti [38], who evaluated the performances of six different state of the art WECs to find which device was the best suited for Italian areas. This work is meaningful for wave energy development.…”

“…In this paper, we selected five different state of the art WECs that were used by Vannucchi and Cappietti [38], including AquaBuoy (>50 m) [39], AWS (>50 m) [40], Pelamis (>50 m) [41], Oyster (≈15 m) [42] and Wave Star (Nearshore) [43], by considering the water depths of S1, S2 and S3 (62 m, 60 m, 16 m, respectively) and the suitable water depths of these WECs. The main features of these WECs are shown in Vannucchi and Cappietti [38].…”

“…The main features of these WECs are shown in Vannucchi and Cappietti [38]. Then, we employed three indices, including the electricity production (P e , kW), capacity factor (C f , %) and capture width (C w , m), which were indicated by Vannucchi and Cappietti [38] to analyze the energy production and determine the best suited WEC in each key location off the coast of China around the Zhoushan Islands.…”

Based on ERA-Interim reanalysis wave field data for the 36 years from 1979 to 2014, the temporal and spatial distributions and development potential of wave energy are studied in detail in the offshore and relatively nearshore waters adjacent to the Zhoushan Islands. The results show that areas of relatively high wave energy are located in the offshore waters to the east and southeast of the Zhoushan Islands. The potential wave energy in relatively nearshore waters (water depths from 10 m to 65 m) is relatively higher and especially in the nearshore waters to the southeast of the city of Taizhou, Zhejiang Province, which are suitable locations for wave energy development. The conclusions provide scientific guidance for wave energy development in the sea areas adjacent to the Zhoushan Islands.

This paper intends to provide the reader with an overview of the Special Issue on Wave Energy Converters. Through 16 contributions from authors of 10 different countries, a number of key topics have been tackled, including resource assessment, engineering design, and financial analysis. As a whole, the Special Issue forms an interesting and helpful compendium on the state of the art of wave energy extraction and exploitation.Keywords: Wave Energy Converters; resource assessment; feasibility study; engineering design Wave Energy (WE) has the potential to be a valuable contributor to the renewable energy mix, as it is abundant, inexhaustible, and relatively well predictable compared to other sources. Accordingly, it has aroused considerable interest over the last twenty years and more than 1000 Wave Energy Converters (WECs) have been patented worldwide.Despite using a wide specter of variants, the working principles of WECs can be conveniently categorized into three groups, namely the Oscillating Water Column (OWC), Wave Activated Bodies (WAB), and OverTopping Devices (OTD). In the OWC technology, a cushion of air is trapped within a partly submerged chamber, where the water level rises and falls with the waves. The oscillating motion forces the air to pass through a turbine, which rotates in the same direction irrespective of the direction of flow. WABs exploit the relative motion of the different parts of the device; hydraulic systems are generally employed to compress oil, air, or water, which are then used to drive a generator. In the OTDs, a sloping plate leads the waves to overtop into a reservoir and the energy is extracted via a turbine that works with small head differences (below 3 m) and large flow volumes.In spite of the large body of work already carried out, WE is still far from being a real competitor of wind and photovoltaic energy, which are now commercially viable alternatives to fossil fuels. In view of this, the following research items deserve greater attention to speed up the development path:(a) Assessment of the available and exploitable resources; (b) New technical solutions to enhance the performance of the devices; (c) Development of engineering tools for reliable technical and economical design; (d) Analysis of the device impact on the marine environment; (e) Development of criteria for optimization of the projects and feasibility analysis; (f) Development of new technologies. This Special Issue includes 16 papers from authors of 10 different countries, which provide the reader with food for thought on each of these topics.
