Abstract
The AquaGen project has developed a prototype water-hydraulic power take-off (PTO) as an alternative to an oil-hydraulic systems. The project has also developed a toolbox of engineering designs, models and manufacturing methods needed to deliver a commercial scale PTO. This has been achieved with funding from the FP7 Support for the Benefit of SMEs programme with the more specific objective of supporting innovative, value-generating start-ups. The engineering development has been completed with the main purpose of providing a direct comparison of the cost benefits of a water-hydraulic PTO against oil hydraulic PTO for the first commercial scale of the FPP Poseidon P80 (a 1.6MW WEC device). A marketing and exploitation plan has been developed primarily focusing on the wave energy conversion application.
