MegaRoller – Follow the Surge!

Tuesday 1 Oct, 13:00 – 14:30


Learn more about the cutting-edge technologies and concepts used in the MegaRoller project at this dedicated side event.

The Horizon 2020 project MegaRoller will develop and demonstrate a Power Take-Off (PTO) for wave energy converters. The PTO is developed in conjunction with oscillating wave surge converters (OWSCs), a class of wave power technology that uses bottom-hinged plates oscillating in pitch following the surge movement of the water particles in the nearshore zone (10m-25m water depth).

If you are already registered for OEE2019, you can register for this side event free of charge by modifying your registration.

The development and demonstration of the PTO for a 1MW OWSC device is based on multiple hardware innovations (modular design, twin drive trains, intelligent cylinders, standardized central power unit and novel accumulator arrangement) and software innovations (wave-by-wave damping control, advanced efficiency control, energy storage control, power smoothing and prediction).

The project will therefore generate extensive know-how in the area of PTO design and PTO control systems, with the aim to decrease the LCOE of next generation OWSC devices below €150/MWh. The methodologies used in the project (such as wave-by-wave damping control and prediction, standardized power units) will be applicable to many other Wave Energy Converter types and generate new standards (algorithms) for PTO control, thus benefiting the broader ocean energy community.

In this side event, consortium members will present the MegaRoller’s activities, an analysis of LCOE, and environmental monitoring practices.
