Oceanlinx is an international renewable energy company with a unique and commercially efficient system for extracting energy from ocean waves and converting it to electricity, or for utilising that energy to produce clean, fresh water from sea water.

Oceanlinx’s core patented technology is an Oscillating Water Column (OWC) device, based on the established science of wave energy, but one which – when compared to other OWC technologies – offers major improvements in the design of the system, the turbine, and in construction technique.

We recognise the importance of patents to protect our intellectual property. Over the years Oceanlinx has invented, developed, tested and overseen many key technological advances, including the Denniss-Auld Turbine. Having worldwide patents in wave energy extraction, turbine blade control and wave energy focusing, allows us to protect our product and continually invest in our objective of maintaining our international leadership in wave energy conversion.

The company’s key strengths are:

• Turbine technology: The patented Denniss-Auld turbine: developed by Oceanlinx, this turbine is revolutionary in being significantly more efficient at converting the energy in the OWC airflow into electricity. The turbine overcomes the endemic problems of turbine stall associated with the bi-directional airflow of OWC systems. The unique characteristic of this turbine is its blade pitch control system which enables it to rotate in the same direction, irrespective of the reversing direction of the air flow.
• Efficiency: The Denniss-Auld turbine is significantly more efficient than the Wells turbine (which is most commonly used in other OWC devices) at converting wave energy into electricity (source: Oxford Oceanics, 2007 – Internal Report)
• Technology maturity: Oceanlinx is one out of only two wave technology developers with full-scale devices deployed to convert wave energy into electricity (source: Emerging Energy Research, 2009)
• Simplicity: The Oceanlinx unit has only one principle moving part, which is located above water. All the technical equipment operates above the water, thereby improving reliability and providing easy access for maintenance and repair.
• Product diversity:  The Oceanlinx unit is capable of producing either clean energy or potable desalinated water, driven by the Denniss-Auld turbine.
• Generic components: The power generation and desalination units are simple and cost-effective, with the majority of the electrical and mechanical parts being “off the shelf” items.
• Proven design:  The technology has been successfully constructed and tested since 2005 with the first full scale Oceanlinx wave plant installed at Port Kembla in NSW, Australia
• Robust: The latest Mk3 design is to deliver 25 years continuous operation and to withstand 1 in 100 year storms, yet can be fabricated in most local workshop facilities.
