A review on technology based on wave energy conversion

Ocean waves are a vast, mostly untapped energy resource, and the potential for collecting energy from waves is enormous. Research in this field is motivated by the need to fulfil renewable energy goals, but is relatively immature compared to other renewable energy technologies. This study presents the overall state of wave energy and analyzes the device types that reflect current wave energy converter (WEC) technology, especially concentrating on work being done inside the United Kingdom. The potential power take-off systems are defined, followed by a study of some of the control methods to improve the efficiency of point absorber-type WECs. There is a lack of consensus on the optimum technique of collecting energy from the waves and, while past innovation has typically concentrated on the idea and design of the main interface, issues emerge about how best to optimize the power train. This essay ends with some recommendations of future advancements.
