The 5 Challenges of Wave Energy Conversion

  • Challenge 1

    How to efficiently convert wave energy into a useful energy form.

  • Challenge 2

    Ease and cost of manufacture, transportation, installation and permitting.

  • Challenge 3

    Adaptability to a wide variety of different locations and ocean conditions.

  • Challenge 4

    Survivability in the ocean over time and maintainability.

  • Challenge 5

    Levelised cost of electricity competitive with other energy generation alternatives.

Our 5 Solutions for Wave Energy Conversion

  • Solution 1

    Having a unique design that harnesses energy from all six degrees of wave movement

  • Solution 2

    A compact, compliant design which is simple to manufacture, can be assembled near to location and is easy to install

  • Solution 3

    Standard design is effective in a range of ocean conditions and is location neutral. Ancillary equipment can be adapted to suit specific locations and conditions.

  • Solution 4

    Survivability in worst conditions is ensured by embracing offshore standards in the design basis, while using composite materials provides a low maintenance operation.

  • Solution 5

    Through simple manufacture and ease of installation and maintenance both Capex and Opex are minimised to facilitate a competitive cost of energy.

The Protean™ Wave Energy Convertor (WEC) system is based upon internationally patented and patent pending intellectual property.
The Protean™ WEC technology has a number of advantages over other wave energy technologies currently being investigated internationally.
Efficient Design: Converts all 6 degrees of wave movement into energy

Low Cost: Durable floating structures designed for survivability and low cost mass production and deployment

Transportable: Sized to be shipped around the world in standard containers

Easy to Install: Designed for simple installation with no need for heavy lift equipment or subsea drilling

Scalable: Easily scalable with additional units being added and removed simply with minimal disruption

Reliable: Using multiple units in an array configuration and fail safe designs provides a relaible source of energy

Inbuilt Energy Storage: Energy is stored using compressed air which enables a low cost, efficient power delivery system to modulate energy supply. 

The Protean™ WEC system is based upon a point-absorber wave energy converter buoy device which floats on the ocean surface and extracts energy from waves by the extension and retraction of a tether to its gravity base on the sea bed. 

The Protean™ WEC is based on globally accepted and proven ocean buoy technology and is designed to withstand the harsh ocean environment; a critical issue for wave energy conversion systems. Major design benefits include:

  • Scalability – the Protean™ WEC system is designed to provide low cost energy for a wide range of applications, from small to large scale production.

  • Versatility – the Protean™ WEC system is designed for dedicated or simultaneous production of electricity or the desalination of seawater.

  • Affordability – the Protean™ WEC system concept provides cost effective, consistent and reliable renewable energy in low and higher energy wave resource locations.

The Protean™ WEC is designed for cost effective manufacture, deployment and maintenance. Its design has been trialled at a small scale in the ocean off Perth, Western Australia, proving the system can successfully convert the power from waves into usable energy. The concept design is based upon a compact architecture which targets power production from a small, low cost design aimed at keeping the projected levelised cost of energy down.

Zero Carbon

Wave energy is a renewable energy resource.

Reliable and constant

Wave's relative reliability and constancy put it way ahead of wind and solar resources. Unlike solar, the wave resource is available night and day, and it is more constant than both wind and solar PV. Estimates suggest the cost of integrating wave into existing energy systems could be 10 per cent less than costs of integrating wind and solar PV.

Predictable Demand

Wave is much more predictable and consistent than other renewables with proven ability to accurately forecast three days ahead. The inherent consistent nature of the wave resource and slowly changing patterns allows for better supply-demand management, planning and integration.

Greater power density

Wave has greater energy density compared with most renewable energies, which means that more energy can be produced from a given environmental footprint.

Proximity to population and industry

Excellent wave resources are located near large populations and industries all around the world – where both electricity and clean water are in high demand. According to the US Department of Energy, 50 per cent of the United States population live within 50 miles of either coast. The Australian Bureau of Statistics states that in Australia 85 per cent of the population lives within 50km of the coast
