Wave motion is slow, powerful and highly fluctuating in the short term, making wave energy devices inherently large and costly.
The peaks of the captured power are more than 10 times higher than the average, even within a given sea state.
The peak power is equivalent to the investment / life cycle cost of a wave energy converter and the average power production over the year is equivalent to the income. Read more
OHT is developing a power take-off (transmission) with power smoothing for wave energy converters based on an ingenious a mechanical gearbox and gravity accumulator that provides a close to constant torque throughout the system and also a constant speed to the generator.
Peak power more than 10 times higher than the maximum allowed output power can be captured and utilized over time without overloading the generator.
The OHT power take-off technology can potentially be used by a wide range of wave energy converters.
Increases power output. High peaks of energy can be captured and utilized over time and the conversion efficiency is increased.
Reduces investment cost. Oversizing of components is greatly reduced which reduces cost of components, all the way from the prime mover to the electrical grid.
Improves quality of power. Power is smoothed before the generator which provides high quality power without using electrical energy storage. Read more
