CETO Wave Power Device Project

 

Harnessing wave energy could provide one of the ways to generate affordable, renewable energy and, in so doing, reduce greenhouse emissions. Renewable Energy Holdings (REH) plc believe the CETO (Cylindrical Energy Transfer Oscillating) wave power device has the potential to do this. They set out to acquire the intellectual property and, to inform the investment decisions, REH commissioned us to review the CETO I device based upon design, model tests and offshore prototype testing.

The CETO (Cylindrical Energy Transfer Oscillating) devices pump high-pressure sea water to shore where it can be used to run a Pelton turbine generator to produce electricity or used to make fresh water through reverse osmosis desalination. The original prototype was CETO I. PB engineers visited the prototype testing site near Fremantle. The visit included viewing the CETO I prototype and associated test facilities and location, as well as collection of the data relating to CETO I and the evolved design for CETO II. This service combined PB's marine engineering capabilities with power generation knowledge.

CETO II is the second generation prototype which is currently undergoing sea water testing and CETO III is the commercial concept. Since our initial report on the CETO device we have been acting as engineering advisor to REH for the CETO project and we have been involved in milestone certification, site specification and site selection. The next step with CETO is the deployment of pre-commercial full scale CETO III devices.
