TWEFDA VERSUS EXISTING TECHNOLOGIES
Continuous Resource: Renewable energies, such as solar or wind, are resources of intermittent availability. Tides and waves are however, although variables, virtually continuous resources.
Capacity Factor: The capacity factor for wind farms was about 37.4% in 2018 reaching 63% with the avant-garde Haliade-X. The estimates for the capacity factor for our ES-Wave are over 80% as a generator and close to 100% by using its dual capabilities.
Small Space: The physical size of the ES-Wave, and the space it requires, are a fraction of what wind turbines would require to create a similar amount of energy. This is because the array of devices can be placed much closer together (wind turbines need to be separated from each other using a larger area because their blades create turbulences in the wind flow; the ES-Wave does not suffer from such interferences) Comparing the Beatrice wind farm (84 turbines and 131 Km²) with our Renewable Energy Hub (6 ES-Wave occupying 18,390 m²), the ratio is more than 500 times less spatial footprint per device.
Easy & Safe Maintenance: The ES-Wave is a lot easier and safer to maintain than a wind turbine. The generator is almost flat to the sea surface, reducing the height a maintenance engineer needs to climb in order to reach their target. For example, the nacelle of wind turbines is situated usually almost at 100 meters or more from the sea surface. Most of the maintenance will be done in the central point of the REH with plenty of space and almost with no risks. If the maintenance needs to be done in the ES-Wave this can be jacked up to be above sea oscillations (meaning that the maintenance operations will be undertaken in a very safe environment). For any major maintenance, the ES-Wave can be disconnected and towed to shore.
