Products [WECs] Wave Energy Conversion Buoys

Wavebob was a wave energy converter which was in development between 1999 and 2013 when the company was closed owing to funding difficulties. [1]


It commenced the first of a number of sea trials in Galway Bay in Ireland during which it was tested as a 1/4 scale device for short periods at the SEAI 1/4 Scale Wave Power Testing facility [2] which is located in the inner bay inside the natural Aran Islands breakwater and where devices under test are exposed to c.1/3 of the expected energy of the 'Full Atlantic Ocean'. [3] [4]

Galway Bay bay

Galway Bay is a large bay on the west coast of Ireland, between County Galway in the province of Connacht to the north and the Burren in County Clare in the province of Munster to the south. Galway city is located on the northeast side of the bay. The bay is about 50 kilometres (31 mi) long and from 10 kilometres (6.2 mi) to 30 kilometres (19 mi) in breadth. The Aran Islands are to the west across the entrance and there are numerous small islands within the bay.

Ireland Island in north-west Europe, 20th largest in world, politically divided into the Republic of Ireland and Northern Ireland (a part of the UK)

Ireland is an island in the North Atlantic. It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest on Earth.

Aran Islands Group of three islands on the west coast of Ireland

The Aran Islands or The Arans are a group of three islands located at the mouth of Galway Bay, on the west coast of Ireland, with a total area of about 46 km2 (18 sq mi). They constitute the barony of Aran in County Galway, Ireland.


Wavebob used the lift and fall of ocean waves to drive generators [5]

The Wavebob consisted of two oscillating structures. These structures must be able to absorb in a variety of conditions and be robust to survive in the harsh marine environment. The structures are controlled by a damping system that can respond to predicted wave height, wave power and frequency. The tank structure (a semi-submerged body) uses captured sea water mass as the majority of its inertial mass. This significantly reduces the cost associated with structural materials.

Wavebob developed its business through an Open Innovation Model and was partnered with leading energy companies such as Chevron and Vattenfall. It briefly established a joint venture company with Vattenfall called Tonn Energy [6] to develop commercial wave farms off the west coast of Ireland.

Wave farm The installment of one or several wave power devices in one place

A wave farm – or wave power farm or wave energy park – is a collection of machines in the same location and used for the generation of wave power electricity. Wave farms can be either offshore or nearshore, with the former the most promising for the production of large quantities of electricity for the grid. The first wave farm was constructed in Portugal, the Aguçadoura Wave Farm, consisting of three Pelamis machines. The world's largest is planned for Scotland.

Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC).

Mullet Peninsula

The Mullet Peninsula —also known as the Mullet and sometimes as the Erris Peninsula—is a peninsula in the barony of Erris in County Mayo, Ireland. It consists of a large promontory connected to the mainland at Belmullet, a town of about 2,000 inhabitants, by a narrow isthmus. There are several villages on the Mullet peninsula including Aughleam, Elly, Corclough and Binghamstown. It is about 33 km long and 12 km wide at its widest parts, and about 200 metres at the narrowest part. Its northernmost point is Erris Head. The peninsula's doglegged shape forms two bays, Blacksod Bay and Broadhaven Bay.

The Pelamis Wave Energy Converter was a technology that used the motion of ocean surface waves to create electricity. The machine was made up of connected sections which flex and bend as waves pass; it is this motion which is used to generate electricity.

An OE Buoy or Ocean Energy Buoy is a wave power device that uses an Oscillating Water Column design. It was deployed in half-scale test mode in Spiddal near Galway in Ireland for over two years between 2007 and 2009.

CETO is a wave-energy technology that converts kinetic energy from ocean swell into electrical power and directly desalinates freshwater through reverse osmosis. The technology was developed and tested onshore and offshore in Fremantle, Western Australia. In early 2015 a CETO 5 production installation was commissioned and connected to the grid. As of January 2016 all the electricity generated is being purchased to contribute towards the power requirements of HMAS Stirling naval base at Garden Island, Western Australia. Some of the energy will also be used directly to desalinate water.

The Oyster is a hydro-electric wave energy device that uses the motion of ocean waves to generate electricity. It is made up of a Power Connector Frame (PCF), which is bolted to the seabed, and a Power Capture Unit (PCU). The PCU is a hinged buoyant flap that moves back and forth with movement of the waves. The movement of the flap drives two hydraulic pistons that feed high-pressured water to an onshore hydro-electric turbine, which drives a generator to make electricity. Oyster is stationed at the European Marine Energy Centre (EMEC) at its Billia Croo site in Orkney, Scotland.

Marine energy or marine power refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world’s oceans creates a vast store of kinetic energy, or energy in motion. Some of this energy can be harnessed to generate electricity to power homes, transport and industries.

Tidal stream generator a type of tidal power generation technology

A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from run of river or tidal estuarine sites. Certain types of these machines function very much like underwater wind turbines, and are thus often referred to as tidal turbines. They were first conceived in the 1970s during the oil crisis.

The Aegir wave farm was a planned wave farm off the south west of Shetland. The project was developed by Aegir Wave Power, a 2009 formed joint venture of Vattenfall and the wave power technology developer Pelamis Wave Power. The wave farm would have had capacity from 10 MW potentially up to 100 MW. Following the collapse of Pelamis in November 2014, the project was cancelled by Vattenfall in February 2015.

Oscillating water columns (OWCs) are a type of Wave Energy Converter (WEC) that harness energy from the oscillation of the seawater inside a chamber or hollow caused by the action of waves. OWCs have shown promise as a renewable energy source with low environmental impact. Because of this, multiple companies have been working to design increasingly efficient OWC models. OWC are devices with a semi-submerged chamber or hollow open to the sea below, keeping a trapped air pocket above a water column. Waves force the column to act like a piston, moving up and down, forcing the air out of the chamber and back into it. This continuous movement force a bidirectional stream of high-velocity air, which is channelled through a Power-Take-Off (PTO). The PTO system converts the airflow into energy. In models that convert airflow to electricity, the PTO system consists of a bidirectional turbine. This means that the turbine always spins the same direction regardless of the direction of airflow, allowing for energy to be continuously generated. Both the collecting chamber and PTO systems will be explained further under "Basic OWC Components."
