The wave energy industry has huge potential

The Commonwealth Science and Industrial Research Organisation (CSIRO) have evaluated the potential market in Australia for Ocean Renewable Energy (ORE). They have low, medium and high cases. The medium case has this type of energy producing 24 TWhr/yr of power by 2050, or 5% of Australia‚Äôs power demands. (Click here to view the CSIRO's report Ocean Renewable Energy: 2015-2050) 

In the Australian context, using Tasmania as an example, ORE would help level the yearly electricity supply load. Tasmania currently has more energy generation in summer. In contrast, wave energy would produce greater energy in winter. 

In a region such as South Australia, there is already a large dependency on highly variable renewable supply. The nature of ORE, is that this technology provides a much more stable supply as wave energy is three times less variable than wind power*.

The advantage of ORE, is that moves Australia energy supply towards meeting its renewable energy targets, doing so with a more reliable steady renewable energy supply.

But the potential is not just limited to Australia. International modelling has also been performed by the CSIRO. They predict the mid range case for installed wave energy capacity by 2025 is 449 GW, which puts the size of the global market at 166 times the size of the Australian market*.

 

The competitive landscape - what are the advantages of AMOG's solution?

Many of the existing Wave Energy Converter (WEC) offers are yet to be fully or successfully commercialised. AMOG has developed a new WEC that offers several advantages over these existing products in this area. 

The AMOG WEC full scale prototype is projected to produce a 50 percentile power of 600kW. If the AMOG WEC takes up 10% of the available wave energy market in Australia (due to competition in wave energy devices), this results in 450 units for Australia alone. Nationally, this technology has the potential to be installed in regions like Western Australia, South Australia, Tasmania, and Victoria.

The base for AMOG's design is a 25m floating vessel with a damped pendulum, the latter based on the principles of Dynamic Vibration Absorbers (also known as Tuned Mass Dampers) which have been used in many technologies since ~1900, including car engines, bridges, cable structures, and even hand-held electrical shavers. In the case of AMOG's WEC, the system is tuned to maximise power from incoming waves, extracting energy from the the pendulum damping via electromotive force (EMF).

This design delivers:

Simplicity.

The novelty of the concept offers tremendous reliability advantages that have plagued other products - the only mechanical moving part is the pendulum connection.

Lower Cost.      

Use of wholly Commercial Off The Shelf components (COTS) keeps construction costs low and it is inexpensive to install.

Survivability.

In survival conditions the mode of operation changes to minimise platform motion. With years of mooring technology experience, AMOG is also investigating release scenarios to enable the vessel to weathervane.

Experience.

AMOG has been working in the floating offshore oil and gas industry for more than 25 years.

AMOG is currently planning a 1/3 scale (approx) technology demonstration of the AMOG WEC. This is planned to occur during Summer 2018 at FaBTest, Falmouth, Cornwall, in the UK.

Why AMOG?

AMOG has been providing high-end engineering consulting services to the offshore oil and gas sector for more than 25 years. Over this time, we have developed a reputation for providing innovative solutions to the complex engineering problems often presented by the challenges of working in ocean environments. 

As Joint Industry Project leaders, AMOG invest heavily in research and development and we have brought this knowledge and experience to the design of our of wave energy device.

For more technical information on AMOG's WEC, you may like to refer to AMOG's peer-reviewed technical paper, "A New Class of Wave Energy Converter - the Floating Pendulum Dynamic Vibration Absorber," published as part of the proceedings of 36th International Conference on Ocean, Offshore and Arctic Engineering.  

 

If you would like more information on AMOG's WEC, or are interested in investing or in partering with AMOG on this project, please contact Dr Hayden Marcollo or Prof Andrew Potts on +61 3 9542 3700.

 

Currently, there are no active RFQs for AMOG FaBTest Project 

 

 

AMOG's Wave Energy Converter is protected by patent (pending).
