The Technology Strategy Board funding follows the support given earlier this month to AWS Ocean Energy by the Scottish Government’s WATERS programme (Wave and Tidal Energy: Research, Development and Demonstration Support).

Funding will further develop AWS Ocean Energy’s AWS-III, a ring-shaped multi-cell surface-floating wave power system.

The funding from the Technology Strategy Board is part of a £7m million funding package awarded to 9 wave and tidal stream research and development projects.

Simon Grey, Chief Executive of AWS Ocean Energy, says: “This latest funding is very welcome as we continue to develop our AWS-III wave energy device.

“Our trials on Loch Ness will restart in September for a 6 week period and thereafter a detailed assessment of the trial results will be undertaken before we start building and then deploy a full-scale version of one of the wave absorption cells.”

A single utility-scale AWS-III, measuring around 60 m in diameter, will be capable of generating up to 2.5 MW of continuous power.

AWS Ocean Energy says it is seeking industrial and utility partners to enable the launching of a 12-cell, 2.5 MW pre-commercial demonstrator in 2012 and subsequent commercialisation of the technology.

The Engineer UK, July 6 2010

Aquamarine Power and AWS Ocean Energy today secured approximately £4.39m to continue development of their wave energy devices.

The WATERS fund (Wave and Tidal Energy: Research, Development and Demonstration Support) has provided Aquamarine Power with more than £3m to develop its 2.4MW Oyster demonstration project in Scotland while AWS Ocean Energy received £1.39m to develop its AWS-III surface-floating wave power device.

Phased installation of the Oyster 2 project will begin at the European Marine Energy Centre (EMEC) in Orkney in Summer 2011. In-depth coverage of Oyster from The Engineer’s 2009 Awards Supplement can be read here.

The Oyster demonstration project will consist of three 800kW hinged flaps, each measuring 26m by 16m. The flaps are moved by the motion of near shore waves, which in turn drive two hydraulic pistons that push high-pressure water onshore to drive a conventional hydro-electric turbine.

Aquamarine Power claims each flap will deliver 250 per cent more power than the original Oyster prototype, which was successfully deployed at EMEC in 2009.

The three devices will be linked to a single onshore 2.4MW hydro-electric turbine. The new devices incorporate modifications that are expected to facilitate the production of more energy, be simpler to install and easier to maintain.

AWS Ocean Energy will use its funding to further develop the AWS-III device, a ring-shaped, multi-cell, surface-floating wave power system.

It is claimed that a single utility-scale AWS-III, measuring around 60m in diameter, will be capable of generating up to 2.5MW of continuous power.

Scale testing of the AWS-III on Loch Ness is currently being carried out to provide design data and confirm the AWS-III’s commercial potential.

The £15m WATERS scheme, which is run and administered by Scottish Enterprise, has been designed to support the construction and installation of pre-commercial full-scale wave and tidal stream device prototypes in Scottish waters.

BBC News, June 11, 2010

A renewable energy company has gone “back to the future” to develop a device to harness power from waves.

AWS Ocean Energy chief executive Simon Grey said its prototype AWS-III on Loch Ness had evolved from “forgotten” technology first seen in 1985.

He said the device could eventually be used in the Northern Isles.

The technology was also tested on Loch Ness in the 1980s, but the Conservative government of the time suspended the wave energy programme.

Highlands Liberal Democrat MP and chief secretary to the Treasury, Danny Alexander, has visited the test site.

He said the progress being made by the company was impressive.

Mr Grey said Inverness-based AWS Ocean Energy was exploring the idea of a machine which had rubber rather than steel components.

Further research led to staff uncovering the similar concept from the 1980s.

He said: “We discovered that the work done in 1985 was rated as the most promising by the Department of Energy at the time.

“We have since taken that design and evolved it further so it is more cost effective in terms of producing power.”

EIGHTIES REVISITED

  • AWS Ocean Energy is updating technology first tested in 1985
  • The Conservatives were also in government at the time
  • Government was funding “green” energy projects then as it is today
  • The film Back to the Future was released in 1985

Mr Grey said the wave energy programme in the 1980s was fully funded by the UK government but the work was later suspended.

He said: “When interest in wave energy re-emerged people assumed that because it hadn’t happened in the past then those ideas wouldn’t work and they had to find new ideas.”

The chief executive said AWS-III was a re-working of a concept people had “forgotten about”.

The ring-shaped machine on Loch Ness is one tenth of the size of the device that could eventually be generating electricity on a commercial scale.

Full-scale machines could be deployed in the sea around Orkney and Shetland following further tests in 2012.

Investment of £2.3m was secured from the Scottish government to develop the AWS-III.

In 2008, AWS Ocean Energy said it had set its sights on winning the world’s largest prize for marine energy innovation.

It said it planned to double its workforce in 12 months, in part to improve its chances of securing the Scottish government’s Saltire Prize.

Following a visit to the test site on Loch Ness, Mr Alexander said: “Power from our seas can make a significant contribution to our energy security and the future of our environment.”
