MegaRoller is a collaborative research and innovation project which aims to develop and demonstrate a next-generation Power Take-Off (PTO) solution for wave energy converters.
The proposed PTO technology for a 1MW oscillating wave surge converters (OWSC) device is based on multiple hardware and software innovations. MegaRoller is therefore expected to generate extensive know-how in the area of PTO design and control system, at the same time decreasing the levelised cost of electricity (LCOE) produced thanks to OWSC devices below €150/MWh.
The methodologies used in the project will be applicable to many other types of wave energy converters. MegaRoller will also propose new standards for PTO control, thus benefiting the whole ocean energy community.
In the short term, the project hopes to increase the power conversion from 70 to 88%, improve reliability of the converters (double the lifetime and service intervals), decrease operation & maintenance costs by 75%, boost power density by 2.8 times and improve power quality.
By 2050, MegaRoller's 40,000 MW power plants could generate 400,000 jobs in Europe only and decrease CO2 emissions by 110 M annually.
