This paper describes one of the innovative wave energy converters under development by the Lancaster University Renewable Energy Group. An offshore point-absorber wave energy converter, PS Frog Mk 5 consists of a large buoyant paddle with an integral ballasted ‘handle’ hanging below it. The...

This paper presents an experimental study of a new resonant-in-surge wave energy converter concept that is a successor to the “Frond” and “Wraspa” WECs investigated at Lancaster University and elsewhere. The concept is of a buoyant, rigid, surface-piercing diaphragm, the edges of which...

The future success of wave energy in the renewable energy mix depends on the technical advancements of the specific components and systems, on the grid access availability and, ultimately, on the economical profitability of the investment. Small and remote islands represent an ideal framework...

An understanding of the fundamental system dynamics of wave energy converters (WECs) is required to safely and reliably benefit from the available wave energy resource to produce electricity. The effects of the geometry, mooring system, and mass distribution on the idealized power takeoff of a...

Ocean is one of the renewable sources of energy that can supply part of the world's energy needs and thus reduce the rate of consumption of fossil fuels and other non-renewable resources. The wave energy can be converted to electricity or other forms of usable energy. Water waves have a...

Recent studies show that there is a correlation between water level and energy absorption values for the studied wave energy converters: the absorption decreases when the water levels deviate from average. The situation appears during tides when the water level changes significantly. The main...

World energy demand is increasing at an alarming rate and producing electricity from alternative or renewable energy sources is becoming necessary. There are many technologies to extract electric energy from sea waves such as: the oscillating water column, the point absorber, the overtopping...

The electrical power integration of a heaving point absorber wave energy converter to a remote island community of population 100 is investigated. A wave resource assessment, taking into account the local geography, is completed. The operational concept and specifications of the wave energy...

Wave energy is a renewable source, which has not yet been exploited to a large extent. So far the main focus of wave energy conversion has been on the large wave energy resources of the great oceans on northern latitudes. However, large portions of the world potential wave energy resources are...

In the first part of the investigation, a new latching control technology is proposed, and it has been shown that the new latching control technique is capable of greatly improving wave energy conversion in regular waves. In this part of the research, a new analysis technique is developed for...
