Seatricity's Oceanus 2 Wave device deployed at Wave Hub

Seatricity has developed the Oceanus wave energy generation technology and undergone several rounds of extensive sea trials of device prototypes in Antigua.

The team has made significant progress in a short space of time and at considerably lower cost than other competitors in the wave energy sector, having achieved hydraulic power generation at EMEC with their Oceanus 1 device.

Seatricity signed a contract with Wave Hub Ltd to install an initial demonstration device in 2014, followed by a 10MW array.

The aim of the demonstration device is to prove the survivability of the scaled up Oceanus 2 device, whilst verifying the power yield available at the Wave Hub site.

The first Oceanus 2 was assembled at A&P Falmouth, with other components being delivered from throughout the UK.

Oceanus 2 is Seatricity’s second generation wave energy device.

In the simplest terms, a float travels up and down with the waves and operates a pump to pressurise sea water which is piped ashore. Many individual pumps are connected together to produce substantial amounts of pressurised water. It is a self latching double acting hydraulic pump point absorber. This means it retracts to the lowest point of the wave trough before pumping.

We have designed, developed and patented what we believe to be the first economically viable, practical and reliable wave energy plant in the world. Seatricity’s technology has overcome many of the challenges encountered by previous attempts at harvesting wave energy in a similar manner. Our team of passionate marine engineers and energy executives have worked tirelessly over the past four years to create a fully working second generation demonstrator device, which has been installed at Wave Hub

Benefits of the Oceanus 2 design:

  • Power capture from even calm seas
  • Uncomplicated design with only one moving part
  • Inexpensive to manufacture from readily available components and easy to service
  • Proven service life of many years
  • No springs, weights, pulleys, gearboxes or other rotating machinery, all of which have a limited life in a marine environment
  • No electrical equipment of any kind is used at sea, except for standard solar powered lanterns used for maritime marking purposes
  • System control is operated onshore with no electrical connection to the units
