Abstract
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.
Highlights
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
Despite using a wide specter of variants, the working principles of Wave Energy Converters (WECs) can be conveniently categorized into three groups, namely the Oscillating Water Column (OWC), Wave Activated Bodies (WAB), and OverTopping Devices (OTD)
The problem of enhancing the efficiency of a WEC of the OWC type was addressed in Experimental Research on Primary and Secondary Conversion Efficiencies in an Oscillating Water Column-Type Wave Energy Converter [3]
Summary
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. 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.
