The Penguin Wave Energy Converter

Wello has solved challenge of producing green energy from oceans by re-purposing existing technologies and business models. The Penguin wave energy converter is based on form and re-purposes existing technologies from wind energy. Supply chain is scalable by using off-the-shelf components and shipyards to manufacture the devices. This simple andpatented device is targeted to produce electricity at lower cost than off shore wind.

From the beginning of the development Wello has been focusing on all five elements of LCOE:

1) Low initial cost

2) Low installation cost

3) Limited maintenance requirement resulting to low operations cost

4) High performance with direct conversion

5) High reliability with enclosed structure, simplicity, industrial components and traditional and proven maritime technology

Wello’s technology is totally unique. It is the only one that converts waves to electricity directly with continuous rotational movement (in comparison to back and forth movement with discontinuity). In a floating element based on shape, motion energy is directly captured by a generator, resulting to direct conversion from motions to electricity without hydraulics, joints or gears. All parts are sealed inside of the floating hull.

Wello is utilizing same components that are used in wind turbines, which means that the WEC will be cost competitive with offshore wind energy. Manufacturing can be done by most shipyards. Deployment can be done cost efficiently with small vessels available locally. Device durability is achieved by having one floating vessel containing all components. In addition to that only industry proven components have been used. Operations and maintenance is easy, it is similar to maintaining any floating device. Remote connection allows also monitoring and adjustment.

Wello’s patented key invention is to convert wave movement to gyration, which is then amplified. Asymmetric shape of the floating device is used to capture the movement to a spinning rotator inside the device. Power is directly led from the rotator to generator using the same shaft eliminating conversion losses.
