AWS Ocean Energy is a Scottish company established to commercialise theArchimedes Wave Swing or AWS wave energy technology

The unique, patented AWS technology will deliver the step-change in

economics needed to make commercial wave power a reality. AWS OceanEnergy has acquired all of the IP rights to this technology

We have tested the technology at full-scale in open water (Portugal 2004)

We have recently raised 2million of institutional investment allowing us toimplement our business plans

We intend to install a pre-commercial demonstrator during 2008. This will befunded via a stock-market (AiM) floatation

Our business model is to deliver the AWS product via strategic partnershipswhilst retaining the IP development within AWS Ocean Energy

Technology principles

The AWS is a submerged air-filled

piston that expands and contracts in

response to wave pressures

Relative movement of the two partsof the device is converted directly to

electricity by a linear generator

Resonant system that can be tuned

to predominant waves

First commercial units rated at

1.25MW sufficient to power 625

homes large wind turbineequivalent

Utility scale, high efficiency, simple,

robust design, minimal maintenance


4/13

AWS Advantages

The AWS has unique advantages due to its sub-

sea location and the unique way in which it

captures power

Storm avoidance in retracted position and robust

design provides high survivability

The minimal maintenance which can be carried out

on-station by ROV provides high availability

High power density reduces footprint and makes

AWS the natural choice for utility developers Environmental impact is minimal and positive effects

on marine life may be experienced

High energy production per tonne of steel ensures

competitive economics

Safety for operatives and other maritime stakeholders

built-in

Key considerations for utility customers making

AWS the only real choice


5/13

Technology verification

The AWS was successfully tested at full scaleoffshore Portugal in October 2004

The tests verified the technology delivering

AWS wave power to the Portuguese grid Power capture met predicted levels and

numerical models are verified for future work

The simplicity and resilience of the device was

demonstrated

The development team gained significant

experience

The operations were carried out without

expensive O & G sector vessels

Selected top in significant 3rd party reviews

Several electricity utilities

Major oil & gas company

AWS MK II Demonstrator project

Pilot plant in Portugal was designed to test technology at full scale but wasnot designed as a long-term demonstrator

Pilot plant was not optimised as a pre-commercial product

Next stage in development process is to achieve long-term demonstration of

the pre-commercial product hence AWS MK II

Key aims for demonstrator are:

Demonstrate safe and reliable construction and deployment

Demonstrate device performance over several seasons

Demonstrate AWS advantages in survivability and low environmental impact

Demonstrate safe and reliable operation and maintenance

Prove initial cost models and verify possibilities for cost reduction to allow pre-

commercial projects

Demonstrator scale to be sufficiently large to provide credible demonstration

of technology whilst containing cost and technical risk


8/13

EU FP6 Project aims

The Proposed EU FP6 has the following specific aims:

Demonstrate practicality of construction process and provide cost indicators for

future cost reduction

Demonstrate practicality, safety and reliability of deployment process

Demonstrate power capture and verify numerical models

Demonstrate survivability in extreme conditions

Demonstrate reliability over full operating range

Demonstrate operational features, including remote shut-down & safety

Demonstrate maintenance procedures

Monitor and assess the environmental effects

Monitor and assess effects on other marine users

Provide a comprehensive report and disseminate information

However for budget reasons only certain key parts of work are to be

supported under the programme

Programme

The programme for the demonstrator is as follows:

We expect commercial sales to follow quickly once the demonstrator

produces first power

First pre-commercial mini-farm is expected to be commissioned by Q3/2009

A view of the future 2050 vision

World energy demand has doubled in 40 years, driven bypopulation growth and economic development in the thirdworld

Development of hydrogen and other enabling technologies

removes current geographical and variability constraints tocontribution by renewables

Environmental and consumer concerns dictate that renewablesprovide a significant proportion of world energy

A mature wave power industry with utility scale developmentsbeing promoted world-wide

Annual capital expenditure on wave power in excess of 1.0billion

AWS Ocean Energy is the global leader in provision of wavepower solutions and expertise with annual profits in excess of150 million
